When we got these awesome Square Le petit Gateaux cupcake papers in stock, I immediately thought of popcorn cupcakes. I baked the cupcake, topped with a little buttercream and then piled on baby white marshmallows. Once the marshmallows were in place, I took some gold lustre on a paint brush and dabbed at the marshmallows, this gave a look of browning and butter. I'm think they look super cute. And with all that marshmallowy goodness, they were super tasty to eat!
