Stir in two-thirds of the bacon.Fill paper-lined muffin cups two-thirds full. Bake at 375 for 18-22 minutes or until a toothpick inserted near the center comes out clean. Cool for 10 minutes before removing from pans to wire racks to cool completely.Frost cupcakes. Sprinkle with remaining bacon; dust with remaining cocoa if desired I would not top with cocoa if using the maple butter cream frosting I would just top with bacon. Refrigerate leftovers.Yield:22 cupcakes.
