  1. I have a question about how to reheat. I am planning on making this is a glass 8×8 baking pan. In order to reheat it says to put it on stove and heat through? Are you thinking that we should defrost it first? I’ve never placed a glass baking pan directly on the stove and I feel like going from frozen to heated in glass will make the pan crack….

    1. Going from frozen to stop top directly would 100% make the glass crack. So yes, you would need to defrost first for sure 🙂
