How to Make Chocolate Peanut Butter Cookies
Be sure to see the recipe card below for full ingredients & instructions!
- Whisk together the dry ingredients in a large mixing bowl. Then beat in the wet ingredients until the dough is smooth.
- Make balls of dough and place them on the prepared baking sheet. Use a fork to press a crisscross pattern into the top of the cookies.
- Sprinkle each cookie with a little extra sugar, and then bake.
- Remove from the oven and allow to cool for 3-5 minutes. Serve and enjoy your cookies!
Ingredient Notes
- Peanut Butter Cookie Mix: Forms the base of our cookies.
- Cocoa Powder: If you want a less chocolatey cookie you can substitute this for ½ cup of chocolate chips instead. The cookie will taste more like a peanut butter cookie and have chocolate pieces in it.
- Egg: Binds the cookie dough together.
- Salted Butter: You can use unsalted butter if you prefer. I always add a pinch of salt when using unsalted butter.


While you can use any unsweetened cocoa powder you prefer, I like to use natural cocoa powder here because the baking soda helps to neutralize the acidity of natural cocoa powder, letting its rich flavor shine.
Peanut butter cookie dough is exceptionally dense and does not spread well in the oven. Adding the criss-cross fork marks presses the dough down to an even thickness, allowing the cookies to bake more evenly.
Absolutely! Simply add ¼ cup of cocoa powder to your favorite peanut butter cookie recipe. You may need to add a bit of water to the dough to make up for the addition of the cocoa powder.
Chocolate peanut butter cookies can become dry if you add too much cocoa powder. Be sure to measure the cocoa powder using a kitchen scale or the spoon-and-level method to ensure that you don’t add too much!

Tips for the Best Chocolate Peanut Butter Cookies
- If you don’t have multiple baking sheets, be sure to cool your baking sheet between batches. You can also cover the cookie dough and refrigerate it between batches to help ensure that the cookies don’t flatten out too much. To help your baking sheet cool faster you can fan it in the air several times or hold it in front of a fan to help cool it.
- Be sure to whisk together the cookie mix and cocoa powder well before adding the other ingredients or you may end up with peanut butter cookie mix chunks in your cookies. The cocoa tends to be fine enough it doesn’t clump but the cookie mix may if not well mixed.
- Don’t overbake the cookies. If they are overbaked, they will get hard and crispy. The cookies should have a set look to them and the edges should be just firm when you remove them from the oven. They will continue to set as they cool.
- These cookies can be eaten warm or cooled. If you want to reheat them you can microwave them for 10 seconds but be sure to include a damp paper towel when doing so to keep the cookies soft!

Peanut butter and chocolate cookies make a wonderful pair, don’t they? These are the perfect cookies to share with family and friends, but we won’t blame you if you have them all to yourself. They’re just that good!
