A light and fluffy healthy smash cake with no butter, no oil, and no sugar. Most importantly (since this cake is meant to make a big mess on baby’s first birthday), this cake just requires five ingredients.

And just like that, our baby girl turned one. We wanted the classic smash cake photo on her first birthday, but every recipe I found seemed overly complicated with fruit purees and a long list of ingredients. I wanted something simple, so to the kitchen I went! And came out many tests later with this little gem – an angel food-inspired healthy smash cake that is light, fluffy, and made with just egg whites, cake flour, cream of tartar, pure vanilla extract, and heavy cream (for topping).

The reality is that a smash cake is just for the baby, so it doesn’t need to be fussy. Make or buy a regular cake for the adults (I served my favorite Chocolate Bundt Cake)but give the birthday girl or boy this little sugar-free birthday cake. He or she will make a glorious mess and you won’t have to worry about baby’s first sugar crash.

What is a Smash Cake

A smash cake is a small cake served to a baby at their first birthday party. The cake is served whole so that the kiddo can “smash” into it, grabbing it with their hands or leaning in to take a big bite. The goal is for the birthday boy or girl to have fun, make a bit of a mess, and for their adoring family and friends to get some sweet photos. (Scroll down for examples of my daughter’s “smash” photos!)

By definition, a smash cake is little. Ideally, it should be baked in a 5×3-inch pan (<– be sure to select the “5×3 inch” size). This little pan seems like a one-trick pony, but I’ve been using mine all summer long to make this cake (with the addition of some sugar) as an afternoon snack for the kids or light dessert for the adults. If you only use the pan once, just pass it on to someone else with a baby that is turning one.

Ingredients for Angel Food Smash Cake

One of the best things about this recipe is that it has very few ingredients. All you need is:

  • Egg Whites – Egg whites are the foundation of this light and fluffy cake. Separate the egg whites and egg yolks carefully to be sure no yolks are in the mix. (Don’t want to waste those leftover yolks? Use them to make lemon curd.) The egg whites eliminate the need for any other leavening like baking powder or baking soda. 
  • Cake Flour – Cake flour has a lower protein content than all-purpose flour, so it creates more tender baked goods. You want your angel food cake to be light and fluffy, and cake flour will help you get there. Don’t skip this ingredient. (And that extra cake flour? Store it in the freezer and later you can use it to make the infamous New York Times Chocolate Chip Cookies.)
  • Cream of Tartar – This acidic powder helps to stabilize egg whites so they stay light and fluffy as they bake. Don’t skip it.
  • Pure Vanilla Extract – This will contribute a light vanilla flavor to the cake. Feel free to skip this ingredient if you’d prefer to keep things simple.
  • Heavy Cream – Heavy cream (or whipping cream) is whipped into a light topping for this cake. This makes a great, unsweetened, “frosting” that leads to wonderful messiness for photos.

Sugar in Baby’s First Birthday Cake

Many people prefer not to give their baby sugar on their first birthday. There’s no reason to add sugar to a smash cake, since most babies will smash the cake and make a fun, photograph-friendly mess without the taste of sugar.

The basic recipe below is for a sugar-free cake which tastes like unsweetened light, fluffy white bread. If you’re okay with a small amount of sugar, you’ll find measurements for adding it. Adding the optional sugar makes this a cake that any dessert-loving adult would also love.

Do you need cream of tartar in angel food cake?

Don’t skip cream of tartar in angel food cake. The cake will rise higher with cream of tartar and will give it that light and fluffy texture that is so unique to angel food cake.

How to Make Smash Cake

A smash cake is a very simple cake made by beating egg whites with cream of tarter and pure vanilla extract until soft, fluffy peaks form. Gently fold in cake flour and a small amount of sugar. Pour the batter into a 5×3 pan and bake at 350 degrees F until golden and set, 20 minutes. Frost with whipped cream, top with berries, and serve to your little one!

Below are the detailed steps with photos.

Step 1: Separate Egg Whites and Egg Yolks

You just need egg whites for this cake. It’s important to carefully separate the egg whites and egg yolks. If any egg yolk is in the mixture, the egg whites won’t form the soft peaks you need in order to give the cake its light, fluffy texture.

You’ll also want to let the egg whites come to room temperature (about 20 to 30 minutes) before making the cake. Room temperature egg whites will beat into soft, fluffy peaks more easily.

Step 2: Beat Egg Whites into Soft, Fluffy Peaks

This is the most important step (and the one I get the most questions about!). Combine the egg whites with cream of tartar and pure vanilla extract and then beat them using a hand mixer or in the bowl of a stand mixer with the whisk attachment. The egg whites need to form soft, fluffy peaks. This should take 3 to 4 minutes of beating on medium-high, but don’t worry so much about the time. Focus on how the egg whites look. When they are properly mixed, the entire mixture will be opaque, white, and evenly fluffy throughout. Look for soft peaks that rise out of the mixture when you lift the beaters out and gently tip over on themselves at the top.

Step 3: Fold in Cake Flour

Gently dust the top of the egg whites with cake flour. Many larger angel food cake recipes have you sift the flour before adding it, but in the small amounts used for this cake, there’s no need to take that extra step. Just sprinkle the flour over top and use a whisk or spatula to gently fold the dry ingredients into the egg whites until evenly combined. Take your time with this step – stirring too hard or fast will compress the egg whites and cause your cake to lose volume.

Step 4: Bake and Invert to Cool

Gently pour the batter into an ungreased 5×3-inch pan (<– be sure to select the “5×3 inch” size). Bake until the top of the cake is light golden brown, about 20 minutes. The baking time may vary slightly depending on the pan you use (see the recipe below for tips.) When the cake comes out of the oven, invert it and cool it upside down. This seems strange but it will help the cake to maintain its height. You can cool it upside down on a cooling rack or just use two small cans or jars to support it.

How to Decorate Your Smash Cake

Keep it simple when decorating this mini cake. Fluffy whipped cream makes the most fun baby messes since it is light and easy for the birthday boy or girl to grab and play with. You can keep it unsweetened or very lightly sweetened if you want to keep sugar to a minimum. While you can use a colorful whipped cream, be careful not to add too much food coloring or it will dye your baby’s face and hands.

The “frosting” for this smash cake recipe is homemade whipped cream made from beating heavy / whipping cream until light and fluffy. For an easy (and photo-friendly) way to add the frosting, transfer the whipped cream to a small ziptop / plastic bag. Seal the bag and then cut off one corner. Gently squeeze the whipped cream out over the top of the cake in billowy rounds. Top it with fresh berries. 

Tip: Wait to frost the cake right before serving so that the whipped cream holds its shape.

Tips for a Light, Fluffy Angel Food Smash Cake

  1. Use a regular pan, not one that is labeled as non-stick. 
  2. Do NOT grease the pan and do  not use parchment paper. As the cake bakes, the egg whites will rise by clinging to the sides of the pan. You will release it from the pan by running a knife around the edges once it cools.
  3. Let the egg whites come to room temperature before using.
  4. Beat the egg whites until soft, fluffy peaks form. Don’t worry so much about the timing, just keep an eye out for opaque, white peaks that stand up and then tip over on themselves at the top.
  5. Gently fold in cake flour. Don’t stir too hard or you’ll compress the air bubbles in the egg whites.
  6. Cool the cake upside down to allow air to circulate and prevent it from sinking as it cools.

Choosing a Pan for Smash Cake

(Updated July, 2020) When I first published this smash cake recipe, I used a 5 x 3-inch springform pan that is no longer available. Since that time, I have been searching for alternative cake pans to recommend. I have tested this cake with all three of the options below:

  • 5×3-inch Cheesecake Pan (BEST OPTION; be sure to select the “5×3 inch” size): for a cake that looks just like the one in these photos, this pan is your best bet. It is exactly the same dimensions as the pan I originally used and makes a sweet little cake with tall sides. (Warning: This is a sturdy pan but it’s a pain to clean. After baking with it, I soak it and then run it through the dishwasher on the top rack.)
  • 5×2-inch Springform Pan: This is a petite little pan that actually measures slightly less than 5 inches wide and 2 inches tall. It is about the same width as the cake shown above, but has shorter sides. The recipe below makes enough batter to fill two of these small pans. I’ve heard from many readers who use two of these pans to make an adorable mini two-layer cake!
  • 6×3-inch Springform Pan: This is a wider pan than I used for these photos with sides that are the same height. The cake it bakes is 1 inch wider than the cake shown above in photos, so it is still a small cake that is great for smashing. Since this pan is slightly bigger than the pan used to create this recipe, I would recommend using the slider in the recipe below to make a double recipe. You may have some leftover batter, but this will insure you have enough batter to fill the pan.

Sifting Cake Flour

Most full-size angel food cakes require sifting the flour to insure that it can be easily mixed in without deflating the egg whites. This step is not necessary of making a single batch of the recipe as written. Just lightly dust the flour over the entire surface of the egg whites before mixing it in. If doubling or tripling the recipe, it’s a good idea to sift the cake flour since you will be using more of it over a small surface area.

Make Angel Food Cake Ahead

To make this cake ahead, bake it according to the instructions and allow it to cool completely. Wrap it in plastic wrap and refrigerate for up to 3 days (let it come to room temperature before serving.) You can also wrap it tightly in plastic wrap and freeze it for up to 4 months (defrost completely before serving).

Healthy Smash Cake Recipe

A light and fluffy healthy birthday smash cake with no butter, no oil, and no sugar. Most importantly (since this cake is meant to make a big mess on baby’s first birthday), this cake just requires five ingredients.
This is an angel food style cake, so be sure to follow the instructions on beating the egg whites and gently folding in the dry ingredients so that the cake will rise high and be light and fluffy. This cake is best baked in a 5×3-inch pan (see the notes for other options).
Prep: 20 minutes
Cook: 20 minutes
Servings: 4

Equipment

  • 5×3-inch round pan

Ingredients 

For Cake:

  • 4 Egg Whites, room temperature (from large eggs; reserve yolks for another purpose or discard)
  • 1/3 cup Cake Flour
  • 3 Tbsp Granulated Sugar (optional; see note)
  • 1/4 tsp Cream of Tartar
  • 1/4 tsp Pure Vanilla Extract (optional; adds flavor but is not neccesary)

For Topping:

  • 1/3 cup Heavy / Whipping Cream
  • 2 tsp Granulated Sugar (optional; see note)
  • Fresh Berries (optional)

Instructions 

  • Before getting started, set out the egg whites and let them come to room temperature (about 20 to 30 minutes). This will make them easier to beat into fluffy peaks.
  • Make cake: Preheat oven to 325°F. Set out a 5×3-inch round pan. Do NOT grease the pan. Place the pan on a sheet pan (just in case any batter spills out as it bakes).
  • If adding the optional sugar, whisk together cake flour and 3 Tbsp sugar in a small bowl. Set aside.
  • Using a hand mixer or in the bowl of a stand mixer with the whisk attachment, combine egg whites, cream of tartar, and vanilla. Beat on medium-high speed until the egg whites form soft, fluffy peaks, 3 to 4 minutes. (Note: This is the most important step in making this cake. Beat the egg whites until the entire mixture is opaque, white, and fluffy throughout. The peaks should stand up straight with a little bit of a curl at the top when you lift the beaters out of the mixture.)
  • Sprinkle the cake flour over the top of the egg whites. Use a whisk or spatula to gently fold the flour mixture in, being careful not to compress the fluffy egg whites.
  • Pour the batter into the springform pan. (Note: Fill the pan right up to the top, rounding it gently with a spatula to create a smooth surface.)
  • Bake until cake is set and the top is a light golden brown, 20 minutes.
  • Remove cake from oven and invert over a cooling rack or two glasses / cans. Allow cake to cool completely upside down (for at least 1 hour).
  • Run a knife around the edges of the cake to gently release it from the pan. 
  • Make whipped cream: Using a hand mixer or in the bowl of a stand mixer, combine cream with 2 tsp sugar (if using). Beat cream on medium-high until light, fluffy, and firm enough to spread over the top of a cake, 3 to 5 minutes.
  • Just before serving (and when the cake is completely cool), spoon whipped cream over top of cake. (Note: If you want an even more photo-friendly topping, you can transfer the whipped cream to a small ziptop / plastic bag. Seal the bag and then cut off one corner. Genty squeeze the whipped cream out over the top of the cake in billowy rounds.)
  • Top the cake with fresh berries, if you'd like. Serve!

Notes

Sugar – Sugar is completely optional. If you prefer a sugar-free option for your baby’s first birthday, just skip all of it. Without sugar, the cake tastes like a light and fluffy white bread.
Sifting cake flour – If making the recipe as written, you should not need to sift the cake flour. Just lightly dust it over the entire surface of the egg whites before mixing it in. If doubling the recipe, it’s a good idea to sift the cake flour since you will be using more of it over a small surface area. This will help to insure that the flour can be easily incorporated (no lumps) without deflating the eggs.
If not serving right away, wrap baked (and cooled) cake in plastic wrap and refrigerate for up to 3 days (let it come to room temperature before serving.) Cake can be frozen, tightly wrapped in plastic wrap, for up to 4 months. Defrost completely before serving.
Baking Instructions for different pans:
  • 5×3-inch Cheesecake Pan: This is my favorite pan for making this recipe. Follow instructions above as written.
  • 5×2-inch Springform Pan: This recipe makes enough batter to fill two of these small pans. Divide batter between two pans (or bake one at a time, refrigerating batter until you are ready to use it) and bake each for 15 minutes.  
  • 6×3-inch Springform Pan: This is a wider pan than shown in photos. Use the slider next to “servings” above to make a double recipe. You may have some leftover batter, but this will insure you have enough batter to fill the pan. Bake this cake for 22 to 24 minutes. 
Allergy Note: This recipe contains dairy, eggs, and wheat. Please follow medical guidance when introducing new foods to your baby, and always talk to your child’s pediatrician if you have questions or concerns about food allergies / sensitivities.

Second only to the smash cake, June’s favorite thing about her birthday was the balloons. She played with them all day long. (So did her big sisters.)

  1. Hi I plan on making this for my son’s first birthday and I currently buy xl eggs (I will be doubling the recipe) I’m wondering if since the recipe calls for 8 large egg whites if I could use 7 xl egg whites and it still be good?

  2. Hi! I tried your recipe. Not sure why is it rock hard 🥲🥲🥲 is it the process of mixing the flour to egg white I did wrongly? I pour the flour into the egg white and mix tgt.

    1. Oh goodness – I’m so sorry to hear that! I’m sure it’s just that the egg whites weren’t beat until they were stiff enough. They really need to hold their shape.

  3. 5 stars
    Hi Jess, I did a test-bake of your recipe last weekend and the cake turned out fluffy as described! I used a 6-inch pan but did not double the recipe and I managed to make a 2-layer cake.

    There are a couple of questions I’d like to ask:
    1) How to keep the top of the cake flat to avoid slicing it thus reducing the cake height?
    2) If I were to make a 3-layer cake, would it be possible for me to do 1.5x of the recipe and divide the batter into 3 6-inch pan? Or does the cake need some height up to the top brim of the pan to rise?

    Appreciate your inputs on these. Thanks a lot!

    1. Hi Tania! The rounded top of the cake is usually a result of the cake baking too hot. Ovens can vary so much in temperature. If you don’t have a thermometer in your oven to double-check the temp, try just lowering the heat by 25 degrees celcius and see if that helps the top to stay flat. It might just need an extra minute or two to bake. But if you’re making a three layer cake, I wouldn’t worry too much about this since you can slice the rounded top off. To your second question – YES! Just do 1.5x of the recipe and divide it between three pans. The batter will rise just fine even if it doesn’t reach the top of the pan, but just keep an eye on the cakes as they bake since you won’t have the exact bake time – just pull them when they’re barely golden brown on top. I hope that helps!
