For best flavor, generously ice the cupcake with a delicious icing before adding the fondant circle. Rolled fondant should be thin.Use either side of the mat. One side will give a raised impression, while the other will give a recessed impression.The diameter of baked and iced cupcakes may vary according to recipe, amount of batter, and amount of icing used. Choose a cutter sized to completely cover the top of the iced cupcake.
