The cakes should start to shrink from the sides of the pans only after removal from the oven. Let the cakes cool in the pans on racks for 10 minutes. Loosen the sides with a small metal spatula and invert onto greased wire racks. To prevent splitting, reinvert so that the tops are up and cool completely before wrapping airtight. Store 2 days at room temperature or 5 days refrigerated.
Texture is best the same day as baking.
