Shimmy Shimmy Cocoa Puff

I wanted to come up with a yummy cupcake for my son's blessing party, so here it is:

Chocolate Banana Pizazz Cupcakes

Ingredients:
3c sifted flour
1 1/2 tsp baking soda
3/4 tsp baking powder
3/4 tsp salt
1 tsp cinnamon
1 1/2 sticks unsalted butter (softened)
1 1/2 c packed light-brown sugar
3 eggs
4 ripe bananas, mashed
3/4 c buttermilk
1/2 tsp vanilla
24 hershey kisses unwrapped
1 can cream cheese frosting
1/4 c peanut butter
1/4 c powdered cocoa

Directions:
Preheat oven to 350.  Line muffin tins.  Whisk dry ingredients in a large bowl.  Cream butter and  brown sugar with mixer attached with the paddle attachment until light and fluffy (about 5 min).  Add eggs, 1 at a time, beating after each addition.
Reduce speed to low.  Mix in vanilla and buttermilk.  Then slowly add the mashed bananas.  Add in dry ingredients in 3 additions.  Divide batter among muffin cups, filling each 2/3 full.  Place a hershey kiss in the center of each cupcake, pressing firmly so it sinks to the bottom and is covered by the batter.
Bake cupcakes 20 min or until tester comes out clean.  Let cool in tin on wire racks.
While cooling, mix frosting and peanut butter together.
Frost  cooled cupcakes with the peanut butter frosting.  Sprinkle with the cocoa powder.  (For a lettered effect, get a sticker in the size and font and letter you like and place it on the cupcake before sprinkling powder, then remove sticker and repeat on the rest)
