Ingredients
(Yields: 15 cupcakes)
- Cupcakes:
 - 4 oz. unsweetened baking chocolate, broken into pieces
 - 3/4 cups (1 1/2 sticks) unsalted butter
 - 2 cups sugar (granulated)
 - 3 eggs
 - 1 t. vanilla
 - 1 c. all-purpose flour
 - 15 Oreo cookies
 - 15 mini Oreo cookies
 - Oreo Buttercream
 - 3 cups powdered sugar
 - 1 cup (2 sticks) unsalted butter, room temperature
 - 2 tablespoons milk
 - 1 teaspoon vanilla
 - 8 Oreo cookies
 
Directions
- Line 15 cupcake holders with paper liners. Preheat the oven to 350 degrees Fahrenheit.
 - Place the chocolate and the butter in a large, microwave-safe bowl. Heat in the microwave on high for about one minute, until the butter is melted and the chocolate is just melted. Give it a good stir to mix it all together.
 - Stir in the granulated sugar, then add the eggs, stirring in one at a time. Then stir in the vanilla.
 - Add the flour and stir well. The batter should be smooth and light-ish brown.
 - Add about a tablespoon of batter to each muffin cup.
 - Place one Oreo cookie on top of each cup of batter.
 - Top with the remaining batter, dividing between the 15 cups.
 - Bake at 350 degrees for 23 – 27 minutes, until the brownies are set but not overbaked. Cool completely.
 - For the buttercream, seal the Oreo cookies in a Ziploc bag and crush with a rolling pin until they’re small crumbs.
 - In a stand mixer with the paddle attachment, mix the butter, powdered sugar, milk, vanilla and Oreo crumbs. Start out on the lowest setting (this helps avoid a powdered sugar blizzard) and then increase to medium once the powdered sugar is well-incorporated. Mix until completely blended.
 - Once the cupcakes are completely cooled, top with the Oreo buttercream. You can use a pastry bag with a big frosting tip, or, if you can’t find yours, a Ziploc bag works in a pinch. Just fill a big bag with the frosting, cut the corner off and squeeze the frosting out the corner onto the cupcake. Magic!
 - Top off with a mini Oreo.
