To make buttercream frosting, MIX unsalted butter, powdered sugar, heavy cream, vanilla extract and fine table salt; use a whip attachment, starting slowly and gradually increasing the speed until light and fluffy. ADD more cream or powdered sugar as needed to get the desired consistency.
● Insert wooden toothpick into cupcakes; if it comes out clean, they are ready.
● Use wooden toothpicks to prop up marshmallow ears if they won’t stay up.
● Do not cut the marshmallows ahead of time. Cut each right before adding the sprinkles to help adhere the sugar.
● If short on time, use boxed cake mix for the batter, and then use decoration instructions to complete.
