Cookie Dough Cupcakes

Are these not the cutest cupcakes you've ever seen? They taste pretty good too. I found this recipe on Annie's Eats. The original recipe had a cookie dough filling inside but I didn't have time to do all of that and I thought they were good without it.
Cupcakes:
3 sticks butter, softened
1 1/2 c. brown sugar
4 large eggs
2 2/3 c. flour
1 tsp. baking powder
1 tsp. baking soda
1/4 tsp. salt
1 c. milk
2 tsp. vanilla
1 c. chocolate chips
Beat butter and brown sugar together until fluffy, about 3 minutes. Add eggs, one at a time. Combine the dry ingredients in another bowl. Add the dry ingredients, alternating with the milk, beginning and ending with the dry ingredients. Blend in vanilla. Fold in the chocolate chips with a spatula. Pour batter into paper lined muffin pans. This recipe made about 24 cupcakes. Bake at 350 degrees for 15-20 minutes. Let cool before frosting.
Frosting:
3 sticks butter
3/4 c. brown sugar
3 1/2 c. powdered sugar
1 c. flour
3/4 tsp. salt
3 Tbsp. milk
2 1/2 tsp. vanilla
Beat the butter and brown sugar until fluffy. Add powdered sugar, flour, and salt. Beat in milk and vanilla. Continue beating until frosting is light and fluffy.
Decorate cupcakes with a tiny chocolate chip cookie and some mini chocolate chips. So cute!
