Strawberry Lemonade Cake - lemon cake mix and strawberry pie filling combine to make one amazing dessert! Top the cake with a quick cool whip lemon pudding frosting. This cake is the most requested cake I make! Lemon cake mix, strawberry pie filling, eggs, vanilla, milk, vanilla pudding mix, powdered sugar, lemon extract, and cool whip. I have to bring it to all of the potlucks I'm invited to. It is always the first dessert to go and everyone asks for the recipe! Make it today!
