I sprayed my pan with a little oil, but I don’t think it’s necessary if you have a non stick pan. Preheat oven to 450F.
Then spread chocolate chips over the bottom of your pan and then layer marshmallows on top.
Bake for 5-7 minutes depending on how toasty you want your marshmallows. For extra crisp, cover with tin foil while baking. Let cool for at least 5 min so you don’t burn yourself, then dive in.
