For the best results, make sure to follow the instructions in this recipe to get dense, flat-topped cupcakes that are perfect for decorating.
Don't overfill the cupcake liners with batter or you'll end up with messy cupcakes. I like to use a 1-tablespoon cookie scoop for this recipe.
If your frosting is too thin, add more powdered sugar until it reaches the desired consistency. You can also add a tablespoon or two of heavy cream or enough milk to help thin out the frosting.
