Note
Maximize the Cereal Flavor: Let the Lucky Charms cereal soak in the milk for at least 20 minutes to extract as much flavor as possible. The longer it steeps, the more flavor gets infused into the batter and buttercream!
Perfecting the Marshmallow Meringue Filling: Ensure the egg whites are at room temperature before whisking, and use a clean, grease-free bowl for the best stiff peaks.
Creating a Beautiful Green Swirl: When piping the buttercream, place the white and green frostings side by side in the piping bag for a seamless swirl effect.
Keeping the Cupcakes Moist: Gluten-free cupcakes can dry out quickly. Be sure not to overbake them, and store them in an airtight container if not serving immediately.
