Key Lime Layer Cake Tastes Like Sunshine

(If you don’t have three pans, the cake can be baked in batches. Bake and cool the first batch of cakes as instructed. After removing the cakes from the pans to cool, wash and dry the pans and then prepare by spraying with cooking spray, lining the bottom with parchment and spraying once more. Pour the batter into the prepared pans and bake as instructed.)
