These cupcakes are my go-to recipe when I'm baking for school functions or birthday parties, the kids love them! You can make the cakes ahead of time and store in an airtight container for 4 days or freeze for up to 2 months. Top them with the buttercream before serving.
Cachous are small sugar pearls used for cake decorating. Find rainbow coloured or silver cachous in the cake decorating aisle at the supermarket.
