Place all ingredients except blueberries into the bowl of a stand mixer or into a blender and whip until light and frothy.
Stir in the blueberries.
Pour into silicone molds or other mini cupcake molds
Bake for 35-40 minutes, or until a toothpick inserted into the center of a cakelet emerges clean.
For best results, wait until they’ve cooled before attempting to unmold. Although if you don’t, you have an excuse to scarf the broken ones before serving the rest.
