I want to make a mushroom cake, can someone tell me how to do one please. Thank you so much.

Do you want a flat one? 2d? 3d?

I love to eat mushrooms, but that doesn't sound like it'd taste all that great!

OK, I'd say if you want a 3d type and you have the ball cake pan or similiar larger bowl type pan, you could do it with several smaller rounds underneath it. You could use a Pyrex bowl if you need to.

I was thinking along the same lines as CakeMan for a 3d one. Small rounds (maybe 6in) and the wonder mold or pamper chef bowl.

For 2d you could do the same thing, just cut it in half and lay it against the board.
