Gluten-Free Single-Layer Yellow Cake Recipe

Elizabeth Barbone

This simple layer cake only takes about an hour to make. It goes well with chocolate buttercream. However, if you don't want to finish the cake with buttercream, a citrus glaze works well. To make, start by zesting your favorite citrus fruit. Then, in a small bowl, combine 1 cup powdered (confectioner's) sugar with 2 tablespoons milk or citrus juice, like lemon or grapefruit. Stir. Add one teaspoon of citrus zest. Thin, as needed, until the glaze is pourable but still thick.
