This month over at Chef-in-Training I am sharing these Reese Double Brookies. Kind of obsessed would be an understatement. This brownie-cookie-Reese’s-Oreo combination is pretty much the ultimate brookie. Are you familiar with a brookie? It’s basically a brownie-cookie that comes in a few different forms.

This version is packed with peanut butter flavor! First of all, I used the new Oreo Reese’s Peanut Butter Cup flavor. Good call Nabisco.

Then I packed in some additional peanut butter flavor with peanut butter chips instead of chocolate chips. Finally, there is about a dozen Reese’s Peanut Butter Cups mixed into the cookie dough. Triple Peanut Butter for the win.

Brookies can be as easy or as complicated as you make them. I often use a boxed brownie mix and then a homemade cookie dough. However, you can totally use the pre-made dough.

I have stuffed my brookies with ButterfingersCadbury eggsThin Mints, and Marshmallow Oreos.  You can alternate the flavors in so many ways!

These Reese’s Peanut Butter Brookies are the perfect combination of brownies and cookies, with Reese’s and Peanut Butter Chips.


For the Brownie Layer

  • 1 Pk Reese’s Oreo Cream Cookies
  • 1 Box (18oz) brownie mix
  • 1 Large egg
  • ⅓ cup Vegetable oil
  • ¼ cup Milk

For the Cookie Layer

  • ½ cup Unsalted butter
  • ½ cup Light brown sugar
  • ½ cup Granulated Sugar
  • 1 Large egg
  • 2 teaspoons Pure vanilla extract
  • 1¾ cups All-purpose flour
  • ½ teaspoon Salt
  • ½ teaspoon Baking soda
  • ¾ cup Peanut Butter Chips
  • 12 Reese’s Peanut Butter Cups


For the Brownie Layer

  1. Preheat oven to 350° F.
  2. In a medium sized bowl, combine brownie mix, egg, vegetable oil and milk. Beat until thoroughly mixed.
  3. Line a 9×13” pan with parchment paper or a baking mat. Pour brownie mixture over the baking mat and spread evenly. Set Oreo cookies in a line over top of the brownie mix.

For the cookie layer

  1. Soften butter in the microwave 10-15 seconds. Combine butter with both light brown sugar and granulated sugar. Mix until smooth and mixture becomes fluffy.
  2. Add egg and vanilla extract and beat until egg is thoroughly incorporated.
  3. In a separate bowl, combine flour, salt and baking soda. Slowly add flour mixture to dough batter while mixing at a low speed. Once all the flour has been added, increase speed to medium until dough forms.
  4. Chop Reese’s Peanut Butter Cups into small pieces. Add all but ¼ C into the cookie dough. Add peanut butter chips and fold into cookie dough.
  5. Take the cookie dough and drop chunks onto the top of the brownie mixture, gently pressing them down into brownie batter. Add remaining ¼ C Reese’s Peanut Butter Cups and press gently onto the top of the cookie dough.
  6. Bake for 23-25 minutes at 350°F. Remove from oven and allow to cool completely before cutting. Since I used a baking mat, I was able to completely remove the sheet of brookies from the pan before cutting.
