Experimenting in the kitchen is a majorly fun, creative way for a group of teenage girls to spend a slumber party. Get busy making the evening's treats such as homemade pizza, ice cream and cupcakes, or even set up a popcorn bar to create some interesting new flavors! It's a fun way to ensure that everyone will be fed for the night; come the morning, another brilliant idea is to make pancakes and waffles for breakfast!
