Instructions
CUPCAKES
Preheat the oven to 350° F. Using the paddle attachment on your mixer, combine the butter and brown sugar. Cream together on medium-high speed until light and fluffy, about 3 minutes. Add eggs one at a time, beating well after each addition and scraping down the sides of the bowl . Whisk the flour, baking powder, baking soda, and salt together in a medium bowl. Alternating add the dry ingredients to the mixer bowl with the milk on low speed, beginning and ending with the dry ingredients, mixing each addition just until incorporated. Blend in the vanilla. Fold in the chocolate chips with a spatula.
Divide the batter evenly between 24 cupcake liners. Bake for 18-20 minutes, until a toothpick inserted in the center comes out clean. Allow to cool in the pan for 5-10 minutes, then transfer to a wire rack to cool completely.
FILLING
Cream butter and sugar in a mixing bowl on medium-high speed until light and fluffy(about 2 minutes). Add flour, sweetened condensed milk and vanilla and beat until smooth. Stir in the chocolate chips. Cover with plastic wrap and refrigerate until the mixture has firmed up a bit, (about1 hour).
After cupcakes have cooled, fill the cupcakes by cutting a cone-shaped portion out of the center of each cupcake. Fill each hole with a chunk of the chilled cookie dough mixture.
FROSTING
Beat butter and brown sugar with the paddle attachment on high speed until creamy and fluffy. Mix in the confectioners’ sugar until smooth. Beat in the flour and salt. Mix in the milk and vanilla extract until smooth and combined.
