You could double layer on a trivet yes
But I could fit 14 in my 7L rectangular one
Or if you can’t do two batches 🙂

How do you put 14 cupcakes in your SC . Is there a stand you can buy to double up on?

Hi, I am wanting to try this. I note the recipe uses egg whites only not the full egg. Is it possible to use the basic cupcake recipe to cook in the slow cooker? Or will it not work? Please advise thanks.
