Cookies & Cream Cupcakes with Peanut Butter-Oreo Buttercream

Oreo cupcakes


My brother's birthday was a few weeks ago, so my mom had us all over for dinner to celebrate. I volunteered to bring dessert and texted him to see what he would like. His response was "something oreo-like" and then later, he said "oreo based, peanut butter based, anything really is good"…hmm. Two years ago, I made him this oreo cake, which was delicious, but a little time consuming. I set out to searching and decided on cupcakes. Not only are they easy to transport, but they were also easier to share leftovers with work colleagues, because let's face it, who is going to want a piece of half eaten cake when they can have their own fresh cupcake? I decided to use this recipe as my post for First on the First this month because the theme was cake decorating, and while I have decorated cakes before, I have never made a "fancy" frosting. Between the frosting, the way it was piped, and the peanut butter cup garnish, I thought that my cupcakes were decorated quite nicely!

For the Cupcakes:
24 Oreos Halves, with cream filling attached 
2 1/4 cups Flour
1 teaspoon Baking Powder
1/2 teaspoon Salt
8 tablespoons Butter, at room temperature
1 2/3 cups Sugar
3 Egg Whites, at room temperature
2 teaspoons Vanilla Extract
1 cup Milk
20 Oreo Cookies, coarsely chopped

Line the wells of two cupcake pans with 24 paper liners. Place an Oreo half in the bottom of each liner, cream side up. In a medium bowl, combine the flour, baking powder, and salt; stir together with a fork and set aside. In the bowl of a stand mixer, combine the butter and sugar and beat on medium-high speed until light and fluffy, about 2 minutes. Add the egg whites, one at a time, beating well after each addition. Add the vanilla extract. With the mixer on low speed, beat in half of the dry ingredients just until incorporated. Add the milk and beat until just combined, then add the remaining dry ingredients. Gently fold in the chopped Oreos with a  rubber spatula until evenly incorporated, being careful not to over-mix. Evenly divide the batter between the prepared cupcake liners. Bak et at 350 degrees for 18-20 minutes, rotating the pans halfway through baking, until a toothpick inserted in the center comes out clean. Allow the cupcakes to cool in the pans for 5-10 minutes, then transfer to a wire rack to cool completely. 

For the Frosting:
1/2 cup Butter, at room temperature
1/4 cup Shortening
1/4 cup Peanut Butter
2-3 cups Powdered Sugar
2-3 tablespoons Milk
Pinch of Salt
3 tablespoons Oreo Crumbs

Separate about 8 Oreos and discard the cream filling. In a food processor or a bag, crush the cookies into fine crumbs. In a large bowl, beat the butter and shortening, on high, until fully combined, then beat in the peanut butter. Scrape down the sides of the bowl and add 2 cups of the powdered sugar, 2 tablespoons of milk, and the salt. Beat the mixture on low, slowly increasing the speed to high, and continue beating for 2 minutes. Add more powdered sugar, 1/4 cup at a time, until you have reached your desired consistency. Add the cookie crumbs and beat on high for 2 minutes.
