Hi all. Hoping to get some clarification. Toward the end of the Warm Nutty Carmel Brownie recipe after you take it out and put it on the cooling rack. Do you seriously just smush the carmels into the brownies or do you just let them melt on top? I'm a little confused. I'd love to try it but would like to have some clarification first. I was also wondering how you handle food allergies, etc. I'm new but with this recipe it would be a concern of mine of what if one of the hosts guests were allergic to nuts. Thanks.
