What is the best way to store leftover brownies?

To keep the brownies fresh, store them in an airtight container. These brownies can be stored at room temperature.

How do you keep the brownies from sticking to the baking pan?

You need to be sure that you’re greasing the baking dish. Before you add the batter to the bottom of the prepared pan, spray it with nonstick spray!

Can I use marshmallow fluff on top instead of marshmallows?

You can get that toasted marshmallow taste however you want. As long as you have some marshmallow goodness on top of these graham cracker squares, you’re going to have good memories and flavors of this dessert!
