Hi Amelia!
Mmm, cupcakes! I must be hungry this morning, because this question spoke to me!
Be Our Guest Restaurant is a family favorite and I adore the Master's Cupcake and the Lemon Meringue Cupcake. I was thrilled when they added the Master's Cupcake to the breakfast menu because it's Disney and regular rules don't apply, right?
When you pre-order your meal, you will pay for it when you arrive and can tell them then that you would like to use a Quick-Service Credit for the meal and a Snack Credit for your cupcake. My experience has been that the cupcakes are a valid Snack Credit, but please be aware that this can change at any time.
Have a delightful dining experience and a wonderful vacation, Amelia! If there is anything else that we are able to assist you with, please send us another question. We'd love to hear from you!
Magical Wishes,
Lauren
