Now imagine all of that nostalgic goodness, baked into a soft, chewy bar you can enjoy anytime. That’s what we’re making today, and trust me, it’s worth every bite.
Behind the Recipe
The idea for these bars came during a chilly evening when I was craving the comfort of s’mores but didn’t feel like setting up a fire pit. So I started playing around in the kitchen and, a few tests later, these heavenly S’mores Bars were born. They’re simple, comforting, and packed with texture and flavor, just like the treat we all know and love.

Turning them into bars is a newer twist, perfect for indoor enjoyment and easy serving. It’s a cozy, mess-free way to experience that classic fireside treat.

- Let the bars cool completely before slicing to get clean, sharp edges.

Kitchen Tools You’ll Need
Nothing fancy, just the basics to get you baking:
Mixing Bowls: For combining your dry and wet ingredients separately.
Hand or Stand Mixer: Helps cream the butter and sugars until light and fluffy.
Rubber Spatula: For folding in the dry ingredients and chocolate chips.
9×9 Baking Pan: The ideal size for even, thick bars.
Parchment Paper: Makes removing the bars from the pan a breeze.
Cooling Rack: So your bars don’t get soggy bottoms.
Ingredients in Best S’mores Bars
These ingredients come together to recreate the classic s’mores flavor in bar form, with a perfect balance of crunch, goo, and sweetness.
- Graham Cracker Crumbs: 1 and 1/2 cups. The base that gives these bars their signature flavor and a hint of crunch.
- Unsalted Butter: 1 cup (softened). Adds richness and holds the crust together.
- Granulated Sugar: 1/2 cup. For sweetness and structure.
- Brown Sugar: 1/2 cup (packed). Adds moisture and a deep, caramel-like flavor.
- Vanilla Extract: 2 teaspoons. Enhances the chocolate and marshmallow flavors.
- Large Egg: 1. Binds the dough and adds structure.
- All-Purpose Flour: 1 and 1/4 cups. The bulk of the dough base.
- Baking Powder: 1 teaspoon. Helps the bars rise slightly and stay soft.
- Salt: 1/4 teaspoon. Balances the sweetness.
- Semi-Sweet Chocolate Chips: 1 cup. Melt into gooey pools of chocolate throughout the bars.

Ingredient Substitutions
Need to swap a few things? No problem.
Graham Cracker Crumbs: Crushed digestive biscuits or vanilla wafers.

Semi-Sweet Chocolate Chips: Milk, dark, or white chocolate chips work too.
Mini Marshmallows: Chop up large marshmallows into smaller pieces.
Ingredient Spotlight
Graham Cracker Crumbs: These bring that toasty, nutty flavor and a slightly gritty texture that mimics campfire s’mores.

Instructions for Making Best S’mores Bars
Alright, let’s get to the fun part—baking! Here are the steps you’ll follow to make these dreamy bars.
- Preheat Your Equipment:
Preheat your oven to 350°F (175°C) and line a 9×9 inch baking pan with parchment paper. - Combine Ingredients:
In a mixing bowl, cream the softened butter with granulated and brown sugar until fluffy. Add the egg and vanilla, beating until well combined. In a separate bowl, whisk together flour, graham cracker crumbs, baking powder, and salt. Gradually mix the dry ingredients into the wet until fully combined. - Prepare Your Cooking Vessel:
Spread two-thirds of the dough evenly into the prepared pan, pressing it into the corners with a spatula. - Assemble the Dish:
Sprinkle the chocolate chips evenly over the dough, then top with mini marshmallows. Drop spoonfuls of the remaining dough on top, leaving some marshmallows exposed for toasting. - Cook to Perfection:
Bake for 25 to 30 minutes, until the edges are golden and the marshmallows are lightly toasted. - Finishing Touches:
Cool completely in the pan on a wire rack before slicing into squares. - Serve and Enjoy:
Slice, serve, and get ready for sticky fingers and big smiles.
Texture & Flavor Secrets
These bars are all about contrast. The graham cracker crust is firm but buttery. The chocolate chips melt into soft pockets of richness. And the marshmallows? They puff and toast to perfection, giving you that golden chewiness that defines a true s’more.
Cooking Tips & Tricks
A little extra care makes a big difference:
- Bake until the edges are just golden—don’t overbake or they’ll be dry.
- For extra gooeyness, press a few extra marshmallows on top halfway through baking.
- Want perfect slices? Chill the pan for 15 minutes before cutting.
What to Avoid
Here are a few common missteps and how to fix them:
- Overbaking: Results in dry bars. Stick to the timer and check the edges.
- Skipping parchment paper: Makes removing bars messy. Always line your pan.
- Under-mixing: Leave no streaks of flour for even texture.
