These are sooooo good! No exaggeration. The topping is light and fluffy and not overly sweet, and you would never know that the cupcakes were vegan. The recipe come from Vegan Cupcakes Take Over the World. Once you taste these cupcakes, there will be no doubt that these can take over the world! The mousse topping makes enough for probably 2 dozen cupcakes, so go ahead and double the cupcake recipe...they are sure to disappear in no time. Preparation time doesn't include the 1 hour refrigeration time for the mousse.
