Pancake Cupcakes!!!!

(From http://thesimpleme.com/2009/06/04/pancake-cupcakes/)

2 cups Original Bisquick mix
1 cup milk
2 eggs
cooking spray
12 tbsp filling: try Nutella, fruit jam, or cream cheese
confectioners sugar for sprinkling
maple syrup for serving

Preheat oven to 400 degrees. Generously coat the bottom & sides of a 12-muffin tin with cooking spray. Make Bisquick pancakes per instructions on the box. Fill each cup in the muffin tin half-way. Add 1 tbsp of filling to the middle of each muffin, then cover with the remaining pancake mix. Bake 20 minutes. Remove from oven, place on serving dish & use a flour sifter to sprinkle with sugar. Serve with warm syrup.

Suggestions from site include putting them in mini muffin tins and baking for 15 min. I would like to add blueberries to the pancake mix.
