I have been making cakes for a while and do NOT know what I did wrong...
I'm making a sheet cake with a star cake on top. I iced each one while frozen (I always do that - makes the cake extra moist, waaay easier for me to smooth the icing, no crumbs in the icing, etc...), and did the writing and piping. I had not stacked them yet, but I left them sitting for a while, and when I returned, I noticed 2 or 3 cracks forming on the top of each cake's icing!
Why did it do this?
How do I repair it without starting over? Will spreading a little more icing over the top 'seal' the cracks back up?
Icing a frozen cake doesn't help cracks... as the cake warms up it expands... and can cause those cracks. Ive heard some people make several small holes in the frozen cake before frosting so it has room to expand.
It looks wonderful! You would never know you had any cracking issues.
