To prepare a zesty lemon celebration cake recipe, you'll first need to prepare your cake batter. You can use any cake mix that you have on hand, but it's best to use an all-purpose flour and baking powder mix. Mix the dry ingredients with the wet ingredients until they're just combined. Pour the batter into the prepared cake pan. Bake the cake for 35 to 40 minutes, or until the toothpick inserted in the center comes out clean. Serve warm or at room temperature.
