You’re baking away in the kitchen and you run out of powdered sugar. You’ve got cookies in the oven and you can’t run to the store! Kila Peeples discovered a way to get more of your key ingredient using two items that you can find in your pantry. Put a half cup of regular sugar in a mixer, along with a tablespoon of cornstarch and mix for about five minutes. Kila tried this out and then made two batches of frosting, one with store-bought powdered sugar, and another with the sugar she made.
