In under an hour, your kitchen will smell like a cozy campfire, and you’ll have a batch of irresistible cookie bars ready to brighten any gathering—or your next quiet night in.

KEY INGREDIENTS IN S'MORE COOKIE BARS

Before diving into the baking action, let’s take a closer look at the star players that make these cookie bars shine. You’re working with straightforward pantry staples, each chosen for the unique texture and flavor it brings to the table.

• Unsalted butter

Brings a rich, creamy base and helps create a tender crumb. By using unsalted, you control the saltiness and ensure the sweetness of the marshmallows and chocolate shines.

• Granulated sugar

Adds clean, granulated sweetness and aids in creating a slightly crisp edge on the bars when they bake.

• Brown sugar

Packed with molasses, it keeps the interior chewy and imparts a subtle caramel note that pairs beautifully with graham crumbs.

• Large eggs

Provide structure and moisture, binding dry ingredients together so the bars hold their shape when sliced.

• Vanilla extract

Enhances all the sweet flavors, rounding out the profile with a warm, aromatic depth.

• All-purpose flour

Forms the backbone of the dough, giving each bar its satisfying cookie texture.

• Graham cracker crumbs

Infuse that unmistakable campfire flavor directly into the dough, reinforcing the classic s’more taste.

• Baking soda

Helps the cookie base rise just enough for a light, tender bite without spreading too thin.

• Salt

Balances sweetness and boosts the richness of both chocolate and marshmallows.

• Semi-sweet chocolate chips

Deliver melty pockets of chocolate throughout, striking the perfect balance between sweet and slightly bittersweet.

• Mini marshmallows

Create gooey, cloud-like pockets that toast lightly on top and stay delightfully soft inside.

• Graham cracker pieces

Layered between dough halves for extra crunch and visual appeal, they reinforce the s’more nostalgia.

HOW TO MAKE S’MORE COOKIE BARS

Time to transform those ingredients into a heavenly tray of dessert bars. Follow each step carefully, and you’ll be rewarded with the perfect balance of cookie chew and marshmallow goo.

1. Preheat your oven to 350°F (175°C). Line a 9x13-inch baking pan with parchment paper, leaving an overhang on two sides to make removal a breeze.

2. In a large mixing bowl, cream together the softened butter, granulated sugar, and brown sugar until light and fluffy, about 2–3 minutes with an electric mixer.

3. Add the eggs one at a time, beating well after each addition to ensure an even texture. Stir in the vanilla extract until it’s fully incorporated.

4. In a separate bowl, combine the all-purpose flour, graham cracker crumbs, baking soda, and salt. Gradually add this dry mixture to the wet ingredients, stirring just until mixed—overmixing can lead to denser bars.

5. Reserve ¼ cup each of the chocolate chips and mini marshmallows for later. Fold the remaining chocolate chips and marshmallows into the dough until they’re evenly distributed.

6. Spread half of the dough into the prepared pan, using a spatula or lightly greased fingers to press down and form a solid base layer.

7. Arrange the broken graham cracker pieces evenly over the dough—this will add extra crunch and that signature s’more look.

8. Dollop the remaining dough over the graham crackers in spoonfuls, then gently spread with a spatula. It’s okay if some graham pieces peek through.

9. Sprinkle the reserved chocolate chips and marshmallows on top for a melty, toasted garnish.

10. Bake for 25–30 minutes, or until the top turns golden brown and the marshmallows have a slight toast.

11. Allow the bars to cool completely in the pan on a wire rack. Once cool, lift out using the parchment overhang, cut into bars, and serve.

HOW TO STORE S’MORE COOKIE BARS

Once you’ve baked these irresistible morsels, keeping them fresh and gooey is all about the right storage method. Whether you plan to enjoy them over a few days or save extras for weeks to come, here are tips to preserve their texture and flavor. Properly stored, these bars maintain that perfect balance of crisp edges and marshmallow softness, ensuring every square tastes as delightful as it did straight from the oven.

• Room temperature, airtight: Place completely cooled bars in an airtight container or a resealable bag, separating layers with parchment paper. Stored at room temperature, they’ll stay fresh for up to 5 days.
• Refrigeration: For a more chilled, fudgy bite, seal bars in an airtight container and refrigerate for up to 1 week. Let them reach room temperature or warm briefly before serving to revive gooeyness.
• Freezing: Individually wrap each bar in plastic wrap, then place in a freezer-safe bag. Freeze for up to 3 months. Thaw overnight in the fridge or at room temperature, then warm in the microwave for that fresh-baked feel.
• Reheating: Whether refrigerated or frozen, pop a bar in the microwave for 10–15 seconds or warm in a low oven (300°F/150°C) for about 5 minutes. This brings back the melty marshmallow peaks and soft cookie crumb.
