We were pleasantly surprised when the 3-layer "magic" cake turned out to be incredibly easy—just six ingredients!—and downright delicious. The magic happens when the cake batter separates into three distinct layers in the oven. Thanks to a low oven temperature (325°F), the liquid-y batter settles into a thick, fudgy bottom layer and a custard center, and the whipped egg whites rise to the top to form the layer of delicate sponge cake. Once you've mastered the basic Magic Cake recipe in this video, feel free to experiment with a bevy of different flavors.
