Oreo Brownie Cookies
Chewy, chocolatey, and a slight crunch. These oreo brownie cookies are delicious and so easy to make! You can make the dough from scratch using our double chocolate cookie dough recipe which uses cocoa powder and chocolate chips (you would use oreo cookie crumbs instead of chocolate chips and make an extra half batch of frosting), but I really love making these cookies with a brownie box mix. The flavor is delicious and it makes for a chewier cookie!
I like rolling the cookie dough in crushed oreo crumbs right before baking. It creates a crispy outer texture. You DO NOT need to do this though. If you prefer a softer texture, simply scoop the dough and bake it! This recipe makes 20-22 cookies.

How To Make Oreo Brownie Cookies
Crushed Oreo Cookies
Crush oreo cookies in a blender or food processor. You’ll need 1 cup of crushed cookies for the brownie batter cookie dough and the rest will be used for rolling the cookie dough balls in and sprinkling over the finished cookies.
Whisk dry brownie mix and 1 cup of cookie crumbs together in a mixing bowl. Add melted butter, eggs, and butter. Mix/stir well.
Chill the dough for 30 mins. in the refrigerator.
Scoop cookie dough balls using a medium cookie scoop (2 Tablespoon size) and roll in crushed cookies.
Place cookie dough balls on a parchment paper-lined baking sheet. The cookies will spread slightly so only bake 6-8 cookies per pan.
Bake cookies in the oven at 375 degrees for 10 minutes.
Let cookies cool on the baking sheet 7-10 minutes before transferring them to a wire cooling rack. Allow cookies to cool completely.
Beat vanilla frosting ingredients together using an electric mixer. Spoon frosting over cooled cookies and sprinkle with crushed cookie crumbs. Store cookies in an airtight container or covered in plastic.
