Its totally normal! The Starbucks ones have to be peeled off too… I think its the nature of the batter. It should peel off quite easily though- if your cupcake is crumbling then its too dry and needs more moisture. I tend to slightly underbake my cupcakes if I’m not filling them as they stay soft and gooey on the inside. Speaking of Starbies, have you tried the red velvet cupcake? Its amazing! The chocolate and vanilla are just meh.
Duuuuuddeee, I’m sad
sweeet!!! good luck! it’ll turn out perfectly, trust me!
