At the MS bakery, everything that is a snack (under $4) has the little sign posted on it. There were lots of sweets listed as snacks.
For counter service, I ordered a cinnamon roll (which are huge - and I know that is said a lot on the DIS boards, but really it was big and airy) and a french toast loaf and a drink and it counted as a CS credit.
I think the cimmamon roll was $4.29 (I am pretty sure it was just over $4) but the french toast loast was just under $4 (this was in May) and the drink was $2.09 (? it was a large fountain drink) I know the total came to $10.65 and it was enough for my mom and I for breakfast.
