Ingredients

• 6 tablespoons unsalted butter (, melted and cooled slightly)
• 1/2 cup lightly packed brown sugar
• 1 teaspoon vanilla
• 1 large egg yolk
• 1/3 cup all-purpose flour (, spooned & leveled)
• 1/2 cup graham cracker crumbs
• 1 and 1/4 cup milk chocolate chips (, or whatever you prefer)
• 1 and 1/4 cup mini marshmallows

How to make S’mores Bars Recipe

Step 1: First things first, preheat your oven to 350°F. Take an 8×8-inch square baking pan and line it with aluminum foil, leaving some overhang on the sides to act as “handles” later. Grease the foil with non-stick cooking spray or a little butter and set it aside.

Step 2: In a medium-sized bowl, combine the melted butter, brown sugar, vanilla, and egg yolk. Use a wooden spoon or spatula to stir everything together. Make sure your butter has cooled down a bit so it doesn’t accidentally cook the egg yolk!

Step 3: Stir the all-purpose flour and graham cracker crumbs into the wet ingredients until just combined. The mixture will be thick, like a cookie dough. Spoon or press this batter into the bottom of your prepared pan, creating an even layer for the crust.

Step 4: Bake the graham cracker crust for about 12 minutes. Once done, remove it from the oven. Now, switch your oven setting from bake to broil.

Step 5: While the crust is still warm, sprinkle the chocolate chips evenly over the top. Let them sit for a few minutes to start melting, then use a spatula to gently spread the chocolate into a smooth, luscious layer. Finish by sprinkling the mini marshmallows all over the melted chocolate.

Step 6: Carefully place the pan back into the oven under the broiler. This part is fast, so don’t walk away! Watch the marshmallows closely for 2-5 minutes until they are puffed and beautifully golden brown on top. As soon as they reach your desired level of toastiness, remove the pan from the oven.

Step 7: Patience is key! Allow the bars to cool at room temperature for at least an hour before cutting. If you’re in a hurry, you can cool them for 10 minutes on the counter and then transfer them to the fridge. They will be incredibly gooey when warm, but letting them cool fully will make for much cleaner slices.

How to serve S’mores Bars Recipe

These bars are divine on their own, cut into squares and served at room temperature. For an extra decadent treat, serve a slightly warm bar with a scoop of vanilla bean ice cream and a drizzle of chocolate or caramel sauce. They are perfect for packing in lunchboxes, bringing to a bake sale, or arranging on a platter for your next party.

How to store S’mores Bars Recipe

Store any leftover S’mores Bars in an airtight container at room temperature for up to 3 days. The marshmallows will be softest on the first day. You can also store them in the refrigerator, which will make them firmer and chewier. For longer storage, you can freeze the bars for up to 2 months. Just be sure to wrap them tightly in plastic wrap and then place them in a freezer-safe bag. Thaw at room temperature before serving.

Tips to make S’mores Bars

• Watch the Broiler: The broiler works very quickly. Marshmallows can go from perfectly toasted to burnt in a matter of seconds. Keep the oven door cracked and your eyes on the prize!
• Use Foil Slings: Don’t skip lining the pan with foil and leaving an overhang. This makes it incredibly easy to lift the entire slab of bars out of the pan for clean, even cutting.
• Cool Completely for Clean Cuts: As tempting as it is to dive in, letting the bars cool completely is the secret to getting sharp, tidy squares. If you prefer a messier, gooier experience, by all means, cut them while they’re still warm!
• Change Up the Chocolate: While milk chocolate is classic for s’mores, feel free to experiment! Dark chocolate chips will add a rich, intense flavor, while a mix of peanut butter chips and chocolate chips is also a delicious combination.

FAQs About S’mores Bars Recipe

Can I use large marshmallows instead of mini ones?

You can, but you’ll need to cut them into smaller pieces first. Mini marshmallows create a more even, consistent topping that’s easier to spread and cut through. If you use whole large marshmallows, you’ll have very large pockets of marshmallow rather than an even layer.

Why did my chocolate seize or get clumpy when spreading?

This can happen if any moisture gets into the chocolate. Be sure your spatula is completely dry. Also, spreading the chocolate chips on the crust right after it comes out of the oven is key, as the residual heat does most of the melting work for you.

Can I use pre-made graham cracker crumbs?

Absolutely! Using store-bought graham cracker crumbs is a great time-saver. If you’re making your own, you’ll need about 8-9 full graham cracker sheets to get 1/2 cup of crumbs. A food processor makes quick work of this.
