Step 1

Prep: Preheat the oven to 325° F. Line two baking sheets with parchment paper or a silicon mat, set them aside.

Step 2

Cookie batter: In a microwave safe bowl, combine the cocoa powder, butter, and shortening. Microwave for 1.5-2 minutes, and stir together until the cocoa fully dissolves. Add the sugar and then mix again until well blended.

Step 3

Stir in the eggs and vanilla extract, mix to combine all ingredients. Add in the dry ingredients, the flour and salt. Mix well and then fold in the chocolate chips.

Step 4

Assemble: Scoop the dough into heaping tablespoons-sized portions of dough and use your hands to divide the dough in half, place an Oreo cookie between the two parts, and then bring the dough up and over to fully enclose the cookie inside.

Step 5

Bake: Place the cookies in the preheated oven and bake for 18-20 minutes. You should be able to see the tops of the cookies crack just slightly.

Step 6

Allow the cookies to cool for about 10 minutes before removing them from the baking sheets. Transfer them to a wire rack and let them cool completely. If the brownie part of the cookie has spread a bit, you can opt to trim it with a knife or cookie cutter. Serve & enjoy!
