Don’t forget about what’s inside the cake. Fruit fillings, custards, or pudding turn your cupcake into a fragile house of cards. They spoil faster than a carton of milk left in the sun. I once made chocolate cupcakes with a cherry compote center, and after six hours on the counter, they started smelling like a science experiment.
If your cupcake is plain vanilla or chocolate with no filling, it’s much more forgiving. Think of it like a loaf of bread—sure, it’ll get a little stale, but it won’t make you sick. Just pop it in the microwave for ten seconds, and it’s party time again.
