Chocolate Peanut Butter Cupcakes

I like to use the Nestle Chocolatier CLASSIC chocolate cake recipe. If you use their other recipe, it has too much of a coffee taste in it.

CAKE
6 oz. Nestle Chocolatier Dark Chocolate bar, melted, and then let cool for five minutes
2 cups flour
1 teaspoon baking soda
1/2 teaspoon salt
1 1/4 cups granulated sugar
3/4 cup softened butter
1 teaspoon vanilla
3 eggs
1 cup milk

Fill cupcake lined muffin tins half full and bake at 350* for 15 minutes.

FROSTING
1 stick softened butter
1 cup peanut butter
2 cups powdered sugar
3 tbsp milk

I crunched up butterfinger for the tops. I suggest not doing this part beforehand if it is going to be a few hours before they're served. They don't stay crunchy on the frosting for more than a few hours.
