Hello Kimberly and welcome back to the Disney Parks Moms Panel!
The simple answer is yes! However, the real answer needs a bit more explanation. In general, things that are
Quick-Service Dining breakfast items are not, of course, considered a snack: pancakes, breakfast platters, etc. Most other items that are not logically a meal and are marked with the purple and white Disney Dining Plan icon are considered snacks. This includes individual fresh fruits, yogurt parfaits, assorted danishes, and...yes... cupcakes! Can cupcakes be eaten for breakfast? The answer is always YES! Each Resort Quick-Service Dining location has somewhat different items available, but I am confident you will find something to feed your morning.
I hope this helps with your planning, if you have more questions, come on back to the Disney Parks Moms Panel- we love to help!
See ya real soon,
Anne
