vanilla-cupcakes-with-rainbow-buttercream

These soft vanilla cupcakes are made using a slightly tweaked version of my signature sponge cake recipe – the same one I use for my layer cakes. They bake up beautifully every time, whether you're making minis or full-sized cupcakes. Finished with a vibrant rainbow swirl of American buttercream, they're perfect for parties, gifting, or just because! This recipe is simple, reliable, and ideal for both beginners and seasoned bakers alike.
