It looks beautiful and tastes like something from a fancy bakery, but the best part is that your kids can help make it. S’mores Cookie Bars are the latest craze in our house because they bring all the joy of a campfire right into our cozy kitchen.
We all crave that perfect mix of crunchy graham crackers, melty chocolate, and gooey marshmallows when the sun starts to set. There is something so nostalgic about these flavors that makes every bite feel like a warm summer memory being made in real time.
I am so excited to share my favorite version of this treat that is simple enough for any afternoon. I promise this will be the easiest way to satisfy that sweet tooth without ever having to light a match.
What Makes This Special
Imagine a soft, buttery cookie that tastes exactly like a graham cracker, topped with thick pieces of milk chocolate and toasted marshmallows that pull apart in the most wonderful way. It is the ultimate comfort dessert that feels both festive and wonderfully simple.
Prep Time: 20 minutes | Cook Time: 30 minutes | Total Time: 50 minutes | Yields: 16 servings
Ingredients You Will Need
For the Cookie Dough
- 1/2 cup unsalted butter, softened
- 3/4 cup granulated sugar
- 1 large egg, room temperature
- 1 teaspoon vanilla extract
- 1 1/3 cups all-purpose flour
- 3/4 cup graham cracker crumbs
- 1 teaspoon baking powder
- 1/4 teaspoon salt
For the Gooey Layers
- 2 cups mini marshmallows
- 7 ounces milk chocolate bars, broken into pieces
How to Make It
Gather your little helpers and get ready for the sweetest kitchen moment of your week.
- Preheat your oven to 350°F (175°C) and line your favorite square baking pan with parchment paper so the bars are easy to lift out later.
- In a large bowl, cream the softened butter and sugar together until the mixture looks light and fluffy like a cloud.
- Add the egg and vanilla extract, beating the mixture until everything is well combined and smells wonderful.
- Whisk together the flour, graham cracker crumbs, baking powder, and salt in a separate bowl until mixed.
- Gradually mix those dry ingredients into your butter mixture until a thick, soft dough forms in your bowl.
- Press half of this cookie dough into the bottom of your prepared pan until you have a nice, even layer.
- Place the chocolate bar pieces over the dough, then scatter the mini marshmallows on top for that classic campfire look.
- Flatten the rest of your dough into small sections and place them over the marshmallows, pressing gently to tuck everything in.
- Bake for 30 to 35 minutes until the top turns a beautiful golden brown and the marshmallows are perfectly toasted.
- Allow the bars to cool completely in the pan before you cut them into 16 squares to ensure they stay together.
Tips for the Best S’mores Cookie Bars
- Use a heavy-duty freezer bag to crush your graham crackers into fine crumbs for the smoothest dough texture.
- Avoid over-mixing the dough once you add the flour to keep the bars soft and tender rather than tough.
- Wait for the bars to be totally cool before slicing so the chocolate and marshmallow layers have time to set firmly.
I hope these bars bring a little bit of that magical summer glow into your home today. There is nothing quite like sharing a gooey treat with the people you love most.
