How could I dry out a cake to use for a show. Instead of using a form. I have searched here but nothing is coming up. I have heard of drying them in the oven but dont know what temperature and for how long. Does anyone have any experience with this?? Thank you

I've seen a recipe for "show cakes" before. It's meant to be used for cakes which must be edible, rather than dummy/styrofoam.

Although it's technically edible, it's neither light nor especially tasty, but it holds up well.

I'll see if I can't find the recipe again. I'm guessing someone here at CC has it.

What if you didn't add any oil or moisture when baking to start with? Then perhaps put it in the oven with just the light on.

You can use RKT too.

A styrofoam dummy would be my first choice. When we didn't know that dummy cupcakes were available, we air dried our own cupcakes for future displays. The problem is they will always ooze oil even years after they're dried as hard as a rock. If you're making a form recipe, just make sure it doesn't include oil.
