has anyone used the pan with the 6 mini scoobys to make cupcakes / mini cakes? Or does anyone know if they can be used for this?

I have not used Scooby, but I did the Spongebob Mini's for my nephews class on his birthday. They were so fun and cute!!

Yes, I've used this pan a bunch of times for my granddaughters and great-nephew & niece. They take longer than you'd think with all the different colors but it is not hard, just time consuming. I like to put some pudding into the cakes and the kids love it.

I was looking at that pan at the store the other day, and the picture on the front was brownies. Then you would have the brown color for Scooby.

Or use Chocolate Cake mix, I do want to try brownie mix the next time.
