Preheat oven to 350ยบ and line a 12-cup muffin tin with cupcake liners.
Prepare brownie batter according to box instructions. In each cupcake liner, add an Oreo. Top with a tablespoon-size ball of cookie dough and top with another Oreo.
Pour over brownie batter mix until each is almost full, fully covering the top Oreo.
Bake until a toothpick inserted in the center of the brownie cup comes out almost clean, 20 to 22 minutes.
Let cool, then make ganache: In a small heatproof bowl, add chocolate chips. Pour over hot heavy cream and let stand 3 minutes, then whisk until smooth and no clumps remain.
Spoon ganache over each cupcake and serve.
