This lemon meringue cake recipe is a showstopper dessert that is sure to impress. The cake is light and fluffy, with a tangy lemon flavor that is balanced by the sweetness of the meringue. To make this cake, you will need flour, sugar, baking powder, salt, eggs, butter, milk, lemon zest, lemon juice, and egg whites. Cream the butter and sugar together, then add the eggs one at a time. Mix in the dry ingredients and the wet ingredients, alternating between the two. Pour the batter into a greased cake pan and bake for 25-30 minutes. To make the meringue, beat the egg whites until stiff peaks form, then gradually add the sugar. Spread the meringue over the cooled cake and bake for an additional 10-15 minutes, or until the meringue is golden brown. Let the cake cool before serving.
