This cake is fabulously make-ahead: simply bake, cool, and frost up to one day in advance. It keeps well in the fridge for 5 days, tightly wrapped. For freezing, wrap unfrosted cake tightly and freeze up to 2 months, or freeze individual frosted pieces for grab-and-thaw treats. Swaps: use a 1:1 gluten-free flour blend, or a vanilla glaze in place of cream cheese frosting. Try a little orange zest, chopped pecans, or sugared cranberries for a twist!
