To start, you need to whip up some chocolate cupcake batter. I prefer my recipe that I have finally figured out for myself, so here it is again if you need it.
Chocolate Cupcake Recipe
2 cups room temperature unsalted butter
2 cups sugar
3 eggs
1 teaspoon vanilla
2 1/2 cups all purpose flour
1 cup cocoa powder
2 teaspoons baking powder
1/2 teaspoon salt
1 box instant chocolate pudding
1 1/2 cups milk
When filling your cupcake liners, fill them slightly over half-way full. If you fill them like normal and then add the cookie dough, your cupcakes will over-flow when they bake.
Now, for your cookie dough, you are more than welcome to mix that up from scratch. I bought a tub of cookie dough and used that. ;)
I used a half tablespoon and scooped out the cookie dough and rolled it into a ball. Place it in the center of your cupcakes and push down slightly. Your cupcakes will bake up around the cookie dough.
Bake these at 350 degrees for about 15-16 minutes. You don't want to over bake these and the cookie dough will settle in the middle when you take them out, so don't panic.
Cookie Dough Frosting
3 sticks butter
3 1/2 cups powdered sugar
2/3 cups packed light brown sugar
1 cup all purpose flour
3 tablespoons milk
2-3 teaspoons vanilla
chocolate chips for garnishing, if desired
I don't usually prefer the taste of alot of butter in a frosting recipe, but for this, it worked well. If you don't like the butter at all (which I usually don't), feel free to substitute it with shortening.
Top your cupcakes with the frosting and chocolate chips, and you're good to go!
