These delicious bars are made with our favorite s'mores ingredients: graham crackers, milk chocolate, and miniature marshmallows. They're easy to make, and you don't need a campfire! Feel free to tailor the recipe with some chopped nuts or coconut, or use semisweet or white chocolate chips. A combination of chocolate and peanut butter would be excellent as well.

The buttery crushed graham cracker crust is topped with milk chocolate chips or plain milk chocolate bars and mini marshmallows for a delicious oven-baked s'mores treat.
