Oreo Peanut Butter Brownie Cakes

Preheat oven to 350ºF and line a 12-muffin baker with paper liners. Spray paper liners with cooking spray.

Prepare brownie batter (oil, sugar, vanilla, eggs, flour, cocoa powder, baking powder, and salt) and leave in the mixing bowl. For each cupcake cup/cake, spread 1 teaspoon of peanut butter over 2 Oreo cookies and stack them on top of each other. Put the stacked Oreos in the cupcake liner with the peanut butter on the top. Spoon 2 tablespoons of brownie batter over each of the stacked Oreos and let it run down the sides of the cookies.

If you have leftover brownie batter, bake separately in a separate pan or muffin tins. Bake cookies and brownies for 20-22 minutes, until brownies are cooked through. Let cool completely then serve.
