This is what I came out with. The cupcake is a chocolate base with Oreo cookie chunks, and the frosting is a vanilla buttercream full of Oreo crumbs. The Oreo filling added such a sweet taste to the frosting, and it was delicious. Casey ate 6. In one day. I think it's safe to say that he enjoyed them.
Here are the recipes I used. Really though, you can just make your favorite chocolate cake recipe and add in some Oreo pieces.
Oreo Cupcakes from HERE
1 1/2 cups all purpose flour
1/2 cup unsweetened cocoa
1 1/4 cup sugar
3/4 teaspoon baking soda
1/2 teaspoon baking powder
1/2 teaspoon salt
2 eggs
1/2 cup vegetable oil
1 teaspoon vanilla
3/4 cup milk
3/4 cup hot water
24 Oreos, broken into pieces
1/2 cup unsweetened cocoa
1 1/4 cup sugar
3/4 teaspoon baking soda
1/2 teaspoon baking powder
1/2 teaspoon salt
2 eggs
1/2 cup vegetable oil
1 teaspoon vanilla
3/4 cup milk
3/4 cup hot water
24 Oreos, broken into pieces
Preheat oven to 350 degrees. Line tray with 12 baking cups. Place Oreo pieces in the bottom of each cup.
Mix the flour, cocoa, sugar, baking soda, baking powder and salt in a large mixing bowl using a wire whisk. Add the eggs, oil, vanilla and milk and mix well until thoroughly combined. Add the hot water and mix until combined. Transfer the batter (it will be very liquid) to a large measuring cup and then pour batter into each baking cup about three quarters full. Bake for 16-18 minutes.
Cookies and Cream Frosting
1 cup (2 sticks) butter
1 pound powdered sugar
2-3 tablespoons milk
Oreo cookie crumbs
For my crumbs, I just put about 12 or so Oreos in the food processor and pulsed them into crumbs.
Beat the butter on medium high speed until it is light and fluffy. Star
t adding in powdered sugar in 1/2 cup batches, and beat until combined, scraping down the sides of the bowl as needed. Slowly add in milk until you have reached the consistency you are looking for. Finally, with the mixer on low speed, add in your Oreo crumbs. I used quite a bit of crumbs because I wanted my frosting to really taste like the cookies. If you prefer a not so chocolaty frosting, just use a small amount.
