Cuisine: American
Ingredients: 1 cup unsalted butter, softened; 1 cup brown sugar; 1/2 cup granulated sugar; 2 large eggs; 2 teaspoons vanilla extract; 2 1/2 cups all-purpose flour; 1 teaspoon baking soda; 1/2 teaspoon salt; 1 1/2 cups graham cracker crumbs; 1 1/2 cups semi-sweet chocolate chips or chopped chocolate; 1 1/2 cups mini marshmallows

Imagine biting into a golden, buttery graham cracker crust layered with gooey marshmallow and melty chocolate, all packed into a soft and chewy cookie bar. These Smores Cookie Bars are everything we love about the classic campfire treat, but baked into a decadent square you can enjoy any time of year. Whether you’re hosting a party, planning a bake sale, or just craving something sweet and nostalgic, these bars deliver comfort in every bite.

What makes these bars irresistible is the contrast of textures—the crisp edges of the cookie dough, the stretchy marshmallow center, and the rich burst of chocolate in every bite. They’re fun to make and even more fun to share, though no one will blame you for keeping a few for yourself.

These bars are not only quick to throw together, but they also use simple ingredients you probably already have in your pantry. No need for a campfire or skewers, just a trusty baking dish and a sweet tooth. They’re perfect for summer gatherings, cozy fall nights, or even as a festive winter dessert when you’re dreaming of warmer days.

What Kind of Chocolate Should I Use?

You can absolutely go with traditional milk chocolate bars for a classic s’mores flavor. However, semi-sweet chocolate chips, dark chocolate chunks, or even a mix of your favorites can bring more depth and richness. If you’re feeling adventurous, try chopped peanut butter cups or caramel-filled chocolate squares for a fun twist.

The charm of this dessert is in its simplicity. Each ingredient serves a purpose to capture that perfect s’mores bite, and together they create a bar that is chewy, melty, and totally addictive.

Mini marshmallows

Step 1: Prepare the Base

Preheat your oven to 350°F and grease a 9×13 baking dish or line it with parchment paper. In a large bowl, cream together softened butter with brown and granulated sugars until light and fluffy.

Step 2: Build the Dough

Beat in the eggs one at a time, followed by vanilla extract. In a separate bowl, whisk together flour, baking soda, and salt. Gradually add the dry mixture into the wet ingredients until just combined. Stir in graham cracker crumbs until evenly mixed.

Step 3: Add the S’mores Magic

Fold in the chocolate and mini marshmallows, saving a small handful of each to sprinkle on top. Press the dough evenly into your prepared baking dish and scatter the reserved chocolate and marshmallows over the surface.

Step 4: Bake to Perfection

Bake for 20 to 25 minutes or until the edges are golden brown and the center is set but still soft. Let the bars cool completely in the pan before slicing into squares for the cleanest cuts.

These bars are best served slightly warm when the marshmallows are gooey and the chocolate is just melty enough. You can easily reheat them in the microwave for 10-15 seconds to get that fresh-from-the-oven feel. This recipe yields about 16 to 20 bars depending on how large you cut them, making it great for sharing.

To store, keep them in an airtight container at room temperature for up to 3 days. For longer storage, refrigerate for up to a week or freeze individually wrapped bars for up to 2 months.

Hot Chocolate or Mocha

The richness of hot cocoa complements the toasted marshmallow and chocolate flavors perfectly.

Cold Brew Coffee

A chilled coffee drink contrasts beautifully with the warm, chewy bar.

Vanilla Ice Cream

Add a scoop on top of a freshly warmed bar for a s’mores sundae vibe.

Strawberry Milkshake

The fruity flavor adds a light contrast to the dense sweetness of the bars.

Whipped Cream and Crushed Nuts

A dollop of cream and a sprinkle of pecans or walnuts adds texture and flair.

Fresh Berries

Serve with strawberries or raspberries for a bright pop of freshness.

Glass of Milk

Sometimes classic is best—cold milk with a gooey cookie bar is simply unbeatable.
