Looks like dessert right? It tastes like it too, but in a package that’s packed with protein and is a hit with my kids, these Peanut Butter Oatmeal Smoothies are on regular rotation for afternoon snacks and just for fun any time of day.

Ever tried adding oats to your smoothies? Apart from the boost of whole grains, they give this recipe a hearty texture that resembles a chocolate peanut butter milkshake. Who doesn’t want that? 

The dominant flavor in this smoothie recipe comes from peanut butter powder. If you’ve never tried peanut butter powder, this is your sign to give it a shot. I love that it has more concentrated peanut flavor without the added heaviness and calories of traditional peanut butter. In a Greek yogurt smoothie, the powder gets blended right in, with a smooth texture and great flavor. And if you’d rather just use creamy peanut butter, that works too! Both options are in the recipe card below. I make this oatmeal peanut butter smoothie recipe at least once a week for breakfasts and snacks, and it truly never gets old.

Why You’ll Love This Peanut Butter Oatmeal Smoothie

As if the creamy texture and sweet, peanut butter chocolate flavor weren’t convincing enough, this recipe comes together with six simple ingredients and optional chocolate chips for topping. 

All you need is a blender and 5 minutes, and it’s ready to drink! Even little ones can’t get enough and often think they’re getting a dessert for breakfast, which makes for a fun treat you can feel good about serving. 

Ingredients 

• Rolled Oats – Quick oats will also work. If gluten is a concern, make sure to look for oats that are certified gluten-free. 
• Greek Yogurt – For the richest taste and creamiest consistency, I recommend full-fat yogurt, but any percentage will work. I typically use plain yogurt, but vanilla tastes great, too, if you want a little extra sweetness. 
• Milk – This blends the ingredients. Use any kind you have on hand. 
• Banana – One banana gives the smoothie the creamiest texture. 
• Ice – Don’t skip this! It’s the key to achieving a thick, fluffy smoothie. 
• Peanut Butter Powder – I find this works so well in smoothies because it gives tons of rich peanut flavor without the richness and calories of classic peanut butter. I buy it at Trader Joe’s or at any grocery store (look for brands like PB2). If you can’t find powder, regular peanut butter works just fine – see the recipe for measurements.
• Chocolate Chips – I use mini chocolate chips because I like to save a few for the top of the smoothie, but regular chocolate chips are totally fine too. 

How to Make It

1. Blend the flavorful and textured – This is important. First blend all of the ingredients except the ice – the rolled oats, peanut butter powder, chocolate chips, banana, Greek yogurt, and milk. Blend until nice and smooth. Take your time with this step to get the oats fully blended so they aren’t gritty in the finished product. 
2. Add the ice – Add the ice and blend until smooth but still cold. 
3. Serve – Pour the mixture into four glasses, sprinkle mini chocolate chips on top, if using, and enjoy! 

Possible Variations and Additions

• Fruit – Add some strawberries or blueberries for a fruity twist. 
• Protein – Include a scoop of your favorite plain, vanilla, peanut butter, or chocolate protein powder. 
• Greens – Mix in a handful of frozen spinach. It might change the color slightly, but you won’t taste it! 
• Flavor Enhancers – Add a dash of cinnamon, vanilla extract, or maple syrup for a slightly different taste. 
• Coffee – Add a shot of espresso for a peanut butter chocolate mocha flavor. 
• Cocoa Powder – Enhance the chocolate flavor further with a spoonful of cocoa powder. 
• Dairy-Free – Use a plant-based yogurt and dairy-free milk alternative to keep this peanut butter oatmeal smoothie dairy-free-friendly. 
• Peanut-Free – Swap the peanut butter powder with an almond powder or cashew powder for a peanut-free option.
