Layer lemon, lime and grapefruit-flavored cakes with lemon curd for a citrus-packed dessert that tastes like spring.
The white cake directions call for egg whites only. Use the leftover yolks to make homemade lemon curd!
Store leftover scraps of cake in the freezer for later if ever you find yourself in need of just a little bite of cake.
Other citrus fruits will work, too! Use the same measurements for peel and juice that are specified above.
