This recipe is a copycat of a chain bakery's delicious cake! Lemon cake mix, lemon pudding mix, sour cream, eggs, oil, lemon juice and water are combined to make this yummy cake batter. A basic cream cheese frosting is made with cream cheese, butter, vanilla and powdered sugar. Piping the frosting on the cake instead of spreading the frosting, makes this lemon cake a double for the bakery version!
