Dark chocolate cake, whole oreo cookie baked into the top, vanilla buttercream mixed with crushed oreos..As you bite into the cupcake, you can see a layer of cookie under the icing
Line cupcake tins with papers and place one oreo cookie in the bottom of each tin. Fill 3/4 way with chocolate cake batter (any chocolate box mix works perfectly or I love Hershey's Perfectly Chocolate Cake recipe). The cookies will float to the top. Bake according to box or recipe, normally around 15-18 minutes. Once cooled, ice with recipe below:
Whip 2 sticks of butter until light and fluffy, gradually mix in 2 1/2 c powdered sugar. Once thoroughly mixed, add in 1 cup crushed oreos (just the cookie side, separate the whites..i sometimes add a handful of the separated whites to the buttercream to give it a more oreo taste.) Mix in 2 tsp vanilla.
Once piped, decorate with oreo chunks or half a cookie as pictured.
