These flourless peanut butter brownie cookies are rich, soft-baked and chewy— that you won't believe that there's no flour or butter! With just 8 ingredients and no chilling, you'll find any excuse to make them. I recommend using mini chocolate chips to pack more into each cookie.

Recipe Testing: What Worked & What Didn't

When I was recipe testing these peanut butter chocolate cookies, I needed to experiment a bit. There were a few modifications that I made in each batch to either the eggs, peanut butter or cocoa powder.

Let me explain how I got here.

Extra Egg: Adding an extra egg not only provides structure to the cookie but it also increases the chewy factor with the extra egg yolk. These cookies needed to be dense, chewy and fudgy so it was a no brainer for me to add the extra egg.
Peanut Butter: I tried a with a few types of peanut butter— homemade, natural and commercial— but found using Jif (or similar) the texture was the best. Though, the others still did come out tasty! I also slightly increased the amount to help bind everything together and to help prevent the cookies from drying out.
Cocoa Powder: Too much made the cookies dry but too little didn't give them enough chocolate to call them "peanut butter chocolate cookies."

Ingredients You Need

This cookie recipe has 9 basic ingredients which allows the flavor to truly shine.

Peanut Butter: Not only does the peanut butter provide flavor, it also acts as both butter and flour in these cookies. You can use homemade or commercial peanut butter, however the type you use will slightly alter the texture. I prefer the texture of Jif.
Sugar: Using a combination of granulated sugar and brown sugar sweetens the cookies and helps keep the center soft.
Eggs: Binds everything together.
Cocoa Powder: It's not a brownie cookie without chocolate. You want to use unsweetened cocoa powder — here's a helpful post to know the difference.
Baking Soda: Helps the cookies rise while baking.
Vanilla Extract & Salt: Flavor!
Chocolate Chips: Optional, but is it a cookie without chocolate chips?

How To Make These Flourless Cookies

These flourless cookies are incredibly simple to make and come together quickly— in just 1 bowl!

Combine Wet Ingredients: Whisk the eggs, peanut butter, sugar and vanilla together until smooth.
Stir in Dry Ingredients: To the dough, fold in the cocoa powder and baking soda until it's well combined. You want the cookie dough to be mixed together well— depending on how thick and/or how cold the peanut butter is, you might have to use some arm muscles.
Add the Chocolate Chips: Fold in the chocolate chips.
Roll into Balls: For each cookie, take about 1.5 Tablespoons of dough. Roll into a ball and place each onto the prepared baking sheet.
Bake: Bake for 9-10 minutes. Slightly press with the back of a spoon to flatten to the cookies and add in a few chocolate chips. The cookies will look very soft and under-baked but that's what you want. As they cool, they will "set" and firm up.

Sure, flourless cookies are nothing new but after these disappeared within a day, I knew that they deserved a place on my website. With soft centers, slightly crumbly edges— these are a texture lover's dream cookie.
