Cookie Dough Cupcakes/Chocolate Buttercream

Cupcakes
Makes 22 to 24 cupcakes (2 1/2 inches each)
Preparation time: 15 Minutes
Baking time: 23 to 27 Minutes
Assembly time: 10 Minutes

24 paper liners for cupcake pans (2 1/2-inch size)
1 package (18.25 ounces) plain yellow cake mix
1 package (3.4 ounces) vanilla instant pudding mix
1 cup whole milk
1 cup vegetable oil
4 large eggs
1 teaspoon pure vanilla extract
1 package (1 pound) frozen cookie dough (see "the Cupcake Doctor says" below)
Chocolate Buttercream (see below)

1. Place a rack in the center of the oven and preheat the oven to 350 degrees F. Line 24 cupcake cups with paper liners. Set the pans aside.
2. Place the cake mix, pudding mix, milk, oil, eggs, and vanilla in a large mixing bowl. Blend with an electric mixer on low speed for 30 seconds. Stop the machine and scrape down the sides of the bowl with a rubber spatula. Increase the mixer speed to medium and beat 2 minutes more, scraping down the sides again if needed. The batter should look well blended. Spoon or scoop a heaping 1/4 cup batter into each lined cupcake cup, filling it two thirds of the way full. (You will get between 22 and 24 cupcakes; remove the empty liners, if any.) Cut the frozen dough pieces in half to make 24 pieces. Place a frozen cookie dough piece on top of each cupcake. Place the pans in the oven.
3. Bake the cupcakes until they are golden and spring back when lightly pressed with your finger, 23 to 27 minutes. Remove the pans from the oven and place them on wire racks to cool for 5 minutes. Run a dinner knife around the edges of the cupcake liners, lift the cupcakes up from the bottoms of the cups using the end of the knife, and pick them out of the cups carefully with your fingertips. Place them on a wire rack to cool for 15 minutes before frosting. They may sink a bit in the center.
4. Meanwhile, prepare the Chocolate Buttercream.
5. Place a heaping tablespoon of frosting on each cupcake and swirl to spread it out with a short metal spatula or a spoon, taking care to cover the tops completely. The cupcakes are ready to serve.
Store these cupcakes, in a cake saver or under a glass dome, at room temperature for up to 3 days or in the refrigerator for up to 1 week. Or freeze them, wrapped in aluminum foil or in a cake saver, for up to 6 months. Thaw the cupcakes overnight in the refrigerator before serving.The

Cupcake Doctor says...
If you use the 18-ounce logs of refrigerated chocolate chip cookie dough (instead of the 1-pound packages of frozen dough), cut them into 24 equal pieces and freeze them before using them in this recipe. It's important to use frozen dough, because you don't want it to bake completely and become a cookie. You want the center to be gooey when you bite into it.

Chocolate Buttercream
Makes 3 cups, enough to frost 24 cupcakes (2 1/2-inch size) generously
Preparation time: 10 minutes

8 tablespoons (1 stick) butter, at room temperature
1/2 cup unsweetened cocoa powder
3 cups confectioners' sugar, sifted
3 to 5 tablespoons milk1 teaspoon pure vanilla extract

1. Place the butter and cocoa powder in a large mixing bowl. Blend with an electric mixer on low speed until the mixture is soft and well combined, 30 seconds. Stop the machine and add the confectioners' sugar, 3 tablespoons of the milk, and the vanilla. Blend with the mixer on low speed until the sugar is incorporated, 1 minute. Increase the speed to medium and beat until light and fluffy, 1 minute more. Add 1 to 2 tablespoons more milk if the frosting is too stiff.

5 Tips for Making Buttercream Frosting
About 3 cups of confectioners' sugar produces the right amount of buttercream frosting for a batch of 24 cupcakes.
Use 1 tablespoon liquid to 1 cup sugar to 2 tablespoons plus 2 teaspoons butter.
Sift the confectioners' sugar to prevent lumps in the frosting.
Begin with soft butter. If needed, soften the butter in the microwave.
For a white buttercream frosting, begin with unsalted butter. Beat it on medium-high with an electric mixer to lighten the color. Use milk as the liquid.

I actually got this recipe from Lindsay Craig when she brought it to a Cowboy watching party at the Leach's home. They are so good!
