I made these cupcakes with my granddaughter. I let her measure all the ingredients and put them in the bowls. My kitchen counter had flour from one end of it to the other. She also proceeded to drop the bag of confectioners’ sugar on the floor but together we cleaned it up. She had so much fun and the cupcakes were delicious. She couldn’t wait for them to come out of the oven.

- Put a mini peanut butter cup on top of the batter before baking. Press slightly into the batter.
- These cupcakes are so moist they don’t really need iced but if you like icing here is a frosting you can make.
