S’mores Cookie Bars: Your New Favorite Treat
If you’re anything like me, you’ve had those evenings where all you want is a cozy fireside s’mores experience but without the fuss of roasting marshmallows. Enter s’mores cookie bars! They combine everything we love about classic s’mores—gooey marshmallows, rich chocolate, and crunchy graham crackers—into a brilliant cookie bar that makes dessert a total breeze.
What Are S’mores Cookie Bars?
S’mores cookie bars are a delightful twist on the traditional campfire treat. Imagine layers of buttery cookie dough studded with chocolate chips, all topped with melty marshmallows and a sprinkle of crushed graham crackers. They’re soft, chewy, and incredibly moreish. Plus, making them requires less effort and cleanup than roasting marshmallows outside. You get to enjoy all those flavors in every bite, perfect for sharing (or keeping all to yourself).
Ingredients Overview for S’mores Cookie Bars
Here’s what you’ll need to whip up these delicious treats:
- Unsalted Butter: About 1 cup, softened. This gives a rich flavor.
- Granulated Sugar: 1 cup for sweetness.
- Brown Sugar: 1 cup packed, adding moisture and a caramel touch.
- Eggs: 2 large eggs to bind everything together.
- Vanilla Extract: 1 teaspoon for that lovely aroma and flavor.
- All-Purpose Flour: 2 cups. This is the structure of your bars.
- Baking Powder: 1 teaspoon to help them rise.
- Salt: A pinch to balance out the sweetness.
- Chocolate Chips: 1 cup, semi-sweet or milk chocolate—pick your favorite!
- Marshmallows: 2 cups, mini or regular. Go for the fluffiest ones you can find.
- Graham Cracker Crumbs: About 1 cup, to mimic the classic s’mores base.
Quick substitution ideas: You can swap unsalted butter for coconut oil if you want a dairy-free version. Brown sugar can be replaced with coconut sugar for a healthier take. And if you’re feeling adventurous, try adding peanut butter instead of some of the butter for a chocolate-peanut flavor.
Step-by-Step Instructions for S’mores Cookie Bars
- Preheat Your Oven: Start by setting your oven to 350 degrees Fahrenheit.
- Prepare Your Pan: Line a 9×13 inch baking dish with parchment paper. This helps with easy removal after baking.
- Cream the Butters and Sugars: In a large bowl, mix together the softened butter, granulated sugar, and brown sugar until creamy.
- Add Eggs and Vanilla: Beat in the eggs one at a time, then stir in the vanilla extract until everything is combined.
- Mix the Dry Ingredients: In another bowl, whisk together the flour, baking powder, and salt. Add this mixture gradually to the wet ingredients until just combined.
- Fold in the Chocolate Chips: Gently mix in the chocolate chips.
- Spread in the Pan: Pour half of the cookie dough into the prepared baking dish, spreading it out evenly.
- Add the Marshmallows: Sprinkle the marshmallows over the dough, followed by the graham cracker crumbs.
- Top with Remaining Dough: Dollop the remaining cookie dough on top of the marshmallows and crumbs; it doesn’t have to be perfect.
- Bake: Place the dish in the oven and bake for 25 to 30 minutes, or until the edges are golden.
- Cool and Slice: Let them cool in the pan for a bit before slicing into squares. Enjoy!
