Kitchen Sink Cookies are soft and chewy cookies packed with chocolate chips, pretzels, potato chips, and toffee (everything but the…). Make them as written, or swap in your favorite mix-ins.
My kids still don’t totally understand why these are called “Kitchen Sink” Cookies, but they know they love them. When I started testing this recipe, with each batch, the kids said more chocolate chips, more pretzels, more potato chips, more toffee!
We packed these cookies full of sweet and salty fillings until they couldn’t possibly hold more. And then we added a few extra chocolate chips. You’re welcome.
Ingredients for Kitchen Sink Cookies
- Unsalted Butter – These cookies were tested with unsalted butter. If using salted butter, skip adding the additional salt.
- Flour, Baking Soda, Kosher Salt, Light Brown Sugar, White Sugar, Egg, Pure Vanilla Extract – Just regular cookie-baking ingredients.
- Mix-Ins – These have a great sweet and salty balance with chocolate chips, toffee bits, potato chips, and chopped pretzels. See below for more ideas!
- Flaked Sea Salt – At our house, we love a light sprinkle of flaked sea salt (I use Maldon) on top of the warm cookies. It’s totally optional but gives the cookies a hint of extra salt and a tiny bit of crunch.
Roll Cookie Dough in Toppings (Optional, but fun!)
It’s purely aesthetic, but if I’m delivering these cookies to someone or serving them to friends and family, I like to roll the dough in some extra toppings. It means that before you take a bite, you get a sneak peak of all the delicious things inside.
How to Freeze Cookie Dough
Frozen cookie dough is like money in the bank. (Though I have to keep it in my downstairs freezer…and out of reach.) You can bake one at a time or the whole batch any time you need them. The best way to freeze cookie dough is:
- Form cookie dough into balls and line up in a single layer on a sheet pan
- Transfer sheet pan to freezer until dough is frozen solid, 2 to 3 hours.
- Transfer dough to a freezer-safe bag and seal, removing as much air from the bag as possible.
- Freeze for up to 6 months.
To bake cookies from frozen: Bake the cookie dough directly from the freezer at 325°F / 163°C for 16 to 18 minutes. (This lower temperature and longer cook time is important for the dough to defrost and cook all the way through.)

These look AMAZING!! So you think the recipe could be modified to be dairy free?
I haven’t tried a dairy-free option, but I bet it could be made to work. If you find a good dairy-free sub please do share!
I make a similar cookie using a flourless peanut butter recipe (1c peanut butter, 1 egg, slightly less than 1c sugar, 1/2tsp baking soda, 1tsp vanilla, 1 pinch of salt). That’s good as is, but i love adding whatever mix ins i can find in the house!
We sub Earth Balance sticks instead of butter in baked goods all the time amd no one would know the dairy difference! (Food allergy life)
These turned out perfect!! I can’t wait to make them again
Yay – so glad you liked them Emily! We made them this weekend too!
My new favorite cookie recipe! It’s just SO good. Thank you! Happy Holidays from the Phils.☺️
Yay! So glad you loved these as much as we do. Happy Holidays!
My cookies didn’t flatten out, they stayed thick and didn’t melt down too much out of the ball shape. They were cakey and crumbly instead of moist and gooey. What could I have done wrong?
You probably didn’t let the butter soften enough.
These cookies are amazing! My whole family loved them and the kids didn’t believe all the fun ingredients that were inside. I even added pecans and shredded coconut the second time I made them. I am amazed that these cookies stay soft – even days after baking. Delicious, Thanks!!
So glad they were a hit with the family! Pecans and shredded coconut sound great!
I made these cookies vegan by subbing in 3 tablespoons of aquafaba instead of 1 large egg, using plant-based butter and dark chocolate. They were AMAZING and all 20 of the cookies I made were eaten at the dinner party of only 8 people! I will definitely be making them again!
Yum – so glad the vegan subs worked!!
Is it okay to freeze with all the Mix-ins (i.e. potato chips and pretzels), or can the dough itself be frozen and then thawed to add all the mix-ins?
I prefer to fold in the mix-ins, form the dough balls, freeze, and then bake straight from frozen. You definitely could make the dough and defrost to add the mix-ins, but in my experience the texture of the mix-ins is good as long as you bake the cookies straight from frozen.
