Highlights of our Simple Peanut Butter Cake Mix Cookies
- Easy prep work & clean up. With minimal ingredients, you can whip up these cookies quickly without much effort. That means an easy clean up too, my kind of recipe!
- No Dough Chilling. Save time with a cookie recipe that doesn’t require chilling the dough, allowing you to bake right away.
- Consistent Texture: Using a boxed cake mix ensures a reliable base, resulting in cookies that are soft on the inside and slightly crisp on the outside.
Cake Mix Peanut Butter Cookie Ingredients
Cake mix: You need one 13.25-oz box of Butter Recipe Yellow Cake Mix.
Water: Add water to moisten the cookie dough.
Peanut butter: 1 full cup of creamy peanut butter will flavor these cookies perfectly.
Eggs: Bind the ingredients together by adding 2 eggs to the dough.
Sugar: Use granulated sugar to create a sweet, crispy cookie topping.
Tips for making Peanut Butter Cookies with a Cake Mix
Full directions are in the recipe card below, but here are a few things to keep in mind:
- Swap out cake mixes! If you don’t have a yellow cake mix, you can use white, butter, or even a chocolate cake mix would be delicious.
- Go chonky! I know so many people love creamy peanut butter but I happen to really enjoy chunky peanut butter. The assed crunch is so tasty.
- Create the classic peanut butter cookie top. Don’t skip the step of making the sugar crisscross topping on these cookies. It adds the traditional look with a bit of added sweetness everyone loves.

Storing & Freezing peanut butter cookies
These cake mix cookies will stay fresh for up to 5 days if stored in an airtight container at room temperature.
For longer storage place them in an airtight container or freezer bag and freeze for up to 3 months. Ensure they are well-wrapped to prevent freezer burn. Thaw at room temperature before serving.
Can you add mix-ins to cookies?
You can absolutely add in ingredients to these cookies! I’d start with about ⅓ or ¼ cup of chopped nuts, mini chocolate chips, mini M&M’s or even mini Reese’s Pieces. They all sound amazing!

Can you make these cookies with a sugar-free cake mix?
Yes, you can use a sugar-free cake mix to make peanut butter cookies! The cookies may have a slightly different texture and sweetness compared to those made with regular cake mix, so mix up the dough and then taste it, to make sure it’s what you’re going for. Feel free to add in a bit of water or more peanut butter to get the right consistency.
