I have two baked chocolate fudge cake layers. One is perfect, the other fell slightly in the center due to slight underbaking. A skewer inserted in the center now comes out clean. Can I still use the layer with the slightly fallen center? I’m thinking to use it as the bottom layer of the 2. Here’s the question: Should I put the top side down on the sunken layer to frost, or should I put the slightly fallen center facing the top so the middle frosting layer covers it?? Please help! I would love to not have to bake a new layer. I need the cake for tonight…eek!
