For the cupcake, use your favorite vanilla cake recipe, or a box mix, whatever you fancy. I used my favorite recipe which is as follows:
1 cup (2 sticks) unsalted butter, room temp.
2 cups sugar
4 large eggs
2 3/4 cup all purpose flour
1 1/2 teaspoon baking powder
1/8 teaspoon salt
1 cup milk
2 teaspoons vanilla.
Preheat oven to 350. Line cupcake pan with paper cups. In a mixer, mix the butter alone for about 1 to 2 minutes, let it get light and airy. Add the sugar and this important, beat the sugar and butter together for 2-3 minutes. This will seriously help your cupcake out! (trial and error) Add the eggs one at a time, allowing the egg to mix for 30 seconds each time...again, this is an important step you don't want to miss! Add in the baking powder, and then gradually add in the flour and last, the milk. Seems a little weird..usually you alternate..but trust me, this recipe works! Add the vanilla, and mix until just blended...be careful not to over mix! (at this point, you could add chopped chocolate pieces in with this if you want a more intense chocolate flavor to your cookie dough palate.) Fill each cupcake paper with about 2 tablespoons of batter, or if you have a ice cream scoop, use that. I tend to under fill the liners, unless I have the large nut cup size Bake for 20 minutes or until the cake bounces back up if touched with your finger..let cool mean while....
Cookie Dough Filling:
4 tablespoon unsalted butter, room temp
6 tablespoons brown sugar
1 cup plus 2 tablespoon all purpose flour
7 ounces sweetened condensed milk
1/2 tsp vanilla
1/4 cup mini chocolate chips..and sense I didn't have those on hand, I just chopped the chips I had into smaller bits..
Cream together the sugar and butter. Add in the flour and then the condensed milk with the vanilla. Mix in the chocolate. You can let the dough chill if you want too...I did not and am glad I went with my gut on this one...I will explain later....
Brown Sugar Buttercream
2 sticks of unsalted butter
1/4 cup or so of brown sugar
mix these together until the sugar is dissolved in the butter and then add:
2 cups powdered sugar
2 tablespoons milk or whip cream
1 tsp vanilla
mix until smooth, add more milk or cream if needed. You want the frosting to be spreadable.
To assemble your cupcakes, Cut a hole in each cupcake using a paring knife, I have also used the back end of a frosting tip..cut the excess cake off the top of your piece of cake you just cut. Fill a piping bag with the cookie dough filling..see, if it was chilled, it would be harder to work with, and I am all for easy steps! Place the top part of the piece of cake you cut back on the cupcake, hiding your filling, and then pipe on the buttercream, sprinkle with chocolate chips...sit back with a glass of milk and bite into heaven!!! :) Oh yeah, repeat the first couple of steps until all the cupcakes are done!
