I'm sure it's the humidity, but the swirls are sliding off my cupcakes. The swirls themselves are not melting, but sliding off in one piece.
I thought about a toothpick between the layers of swirl but that only (potentially) works if I deliver them.
Thought also about roughing up the top of the cupcake a bit where no one would see it, but not sure that would work.
Last night I sifted dry ingredients for five carrot cakes including 2 t of cinnamon/batch. There was much sneezing. Last night my throat and nose were burning. Today I my sinuses are a mess. So... Cinnamon or coincidence--thoughts?
