Chocolate Lemon Cake

A moist chocolate cake filled with lemon curd with lemon Swiss meringue buttercream.

Chocolate and lemon may seem like an odd combo, but it's delicious in this chocolate lemon cake! The tart lemon curd filling and lemon frosting offset the rich, moist chocolate sponge.

Flour, sugar, cocoa powder, baking powder, baking soda, salt, egg, egg white, oil, buttermilk, vanilla, coffee, and lemon curd (for the filling).

First, combine the egg, egg white, oil, buttermilk, and vanilla extract. Whisk together vigorously.

Step 1

Add the flour, sugar, cocoa powder, leaveners, and salt to a large bowl. Fold the wet ingredients in with a rubber spatula. Then mix in the coffee.

Once the butter is incorporated, beat in the lemon juice until the frosting is smooth and creamy.
