Neapolitan Marshmallow Treats
Layers of vanilla, chocolate, and strawberry create the most adorable potluck dessert ever!
Wrap bars individually in plastic wrap and place in an airtight container. Store at room temperature up to 1 week.
To weight the cookies down, cover the surface with a sheet of waxed paper and a sheet of foil. Place another 13x9-inch baking pan on top of cookies; add a few unopened cans of food to the top pan for weight.
