To make the cake she needed to bake 4 rounds cakes, and let them cool, while she went out.
My instructions were: When the timer goes off, check them, when they're done, put them somewhere to cool.
In the end MaryBeth told me, "Just put them in the garage upside down on a sheet with something heavy on top of them."
Well I think this is appropriate. It is the garage after all!
I guess I could have made the title of the post, 'Have you ever used polyurethane and a hammer to make a cake?'
