Place paper baking cups in muffin pans, and lightly coat with cooking spray. Spoon batter into cups, filling them ¾ full.
03Bake at 350°F for 20 to 25 minutes or until a wooden toothpick inserted into the center of a cupcake comes out clean. Remove the cupcakes from the pan and cool completely on a wire rack.
04Blend softened cheese and butter in mixer. Add sugar and vanilla. Beat in enough milk or cream to reach desired consistency. Frost each cooled muffin with a bit of frosting before serving.
