Use the highest quality ingredients you can. Add a flavorful jam or lemon curd in the center of the cupcake by removing a little of the middle, filling and then piping frosting over the top.Make sure to beat the butter and sugar until light and fluffy. When adding the liquid ingredients, add them very slowly as the mixer is beating. Baking times are different for each oven, so tap the top of a cupcake to see if it's baked through. Frost these cupcakes with our creamy buttercream frosting!
