Ingredients for S’mores Cookie Bars
Creating the perfect S’mores Cookie Bars requires some simple yet essential ingredients. Let’s dive into what you’ll need to bring these delightful treats to life!
- Unsalted Butter: Start with ½ cup (8 tablespoons or 113g), softened to room temperature. This is key for that perfectly creamy texture.
- Brown Sugar: You’ll need ¾ cup (150g), packed. This adds a deep, rich sweetness that complements the s'mores flavor.
- Egg: One large egg at room temperature helps bind the ingredients together, creating a deliciously chewy bar.
- Vanilla Extract: A teaspoon of pure vanilla extract elevates the flavor profile, making each bite irresistible.
- All-Purpose Flour: One cup (125g), spooned and leveled, is needed for the cookie base. This gives structure to your bars.
- Graham Cracker Crumbs: Use 1 cup (120g), which you can make from about 8 full-sheet graham crackers. This is a must for that authentic s’mores taste!
- Baking Powder and Salt: Just ½ teaspoon of baking powder and ¼ teaspoon of salt enhance the flavors beautifully.
- Semi-Sweet Chocolate Chips: One cup (180g) adds that melty, chocolatey goodness we all crave in a s'mores dessert.

Preparing S’mores Cookie Bars
Making S’mores Cookie Bars is a delightful way to revisit childhood memories while indulging in a sweet treat that’s perfect for any gathering. Follow these simple steps to bring this delicious recipe to life.
Gather your ingredients
Before you get your hands doughy, it’s crucial to gather all the ingredients. Here’s what you’ll need:
- ½ cup unsalted butter (softened)
- ¾ cup packed brown sugar (light or dark)
- 1 large egg (room temperature)
- 1 teaspoon pure vanilla extract
- 1 cup all-purpose flour
- 1 cup graham cracker crumbs (about 8 full sheets)
- ½ teaspoon baking powder
- ¼ teaspoon salt
- 1 cup semi-sweet chocolate chips
- 1 heaping cup marshmallow creme
Don’t forget to preheat your oven to 350°F (177°C) and line your baking pan with parchment paper! This ensures easy removal once your delectable creation is ready.
Cream the butter and sugar
In a large mixing bowl, you’ll want to cream the unsalted butter and brown sugar together. Beat them on medium-high speed for about 3 minutes until it looks fluffy and smooth. It’s a fun step where all the magic begins! Then, add in the egg and vanilla extract, blending until combined. You might notice the mixture seems a bit curdled; don’t worry, that’s totally normal!
For extra tips on this step, you can check out this guide on how to cream butter and sugar.
Combine dry ingredients
In a separate bowl, whisk together your all-purpose flour, graham cracker crumbs, baking powder, and salt. This combination not only binds the bars but also provides that essential graham cracker flavor. Gradually mix this dry blend into the creamed mixture at medium speed until everything is well combined. You’ll see it transform into a sticky yet heavenly dough.
Assemble your bars
Now comes the fun part: assembling your S’mores Cookie Bars. Press about two-thirds of the cookie dough into the prepared pan—don’t stress if it’s a bit uneven! Next, spread a layer of marshmallow creme on top carefully; it can be quite sticky. Then sprinkle your chocolate chips evenly. Finally, mold the remaining cookie dough into flat pieces atop the chocolate chips, letting some of the delicious layers peek through.
Bake to golden perfection
Place your creation in the oven and bake for 25-30 minutes. Keep an eye on them; the bars should be lightly golden brown when done. Once they’re baked to perfection, transfer the pan to a wire rack and allow the bars to cool completely. This patience pays off big time when you finally cut into those gooey, chocolate-filled delights!
Now that you know how to prepare your S’mores Cookie Bars, you can enjoy this sweet adventure any time you want! Whether it's for a casual night in or a backyard get-together, these bars are sure to be a crowd-pleaser.

Variations on S’mores Cookie Bars
S’mores Cookie Bars with a Twist
Want to elevate your S’mores Cookie Bars experience? Try adding a swirl of peanut butter or Nutella to the marshmallow layer for a deliciously creamy surprise. You could also sprinkle in some chopped nuts for added crunch, or switch up the chocolate by using dark chocolate chips or white chocolate for a unique flavor profile.
Gluten-Free S’mores Cookie Bars
For those following a gluten-free diet, creating S’mores Cookie Bars is simple! Substitute the all-purpose flour with your favorite gluten-free flour blend. Just ensure the graham cracker crumbs are also gluten-free, which are available at many grocery stores or online. Enjoy the same gooey, sweet goodness without the gluten!
By exploring these variations, you'll find the perfect way to customize your cookie bars to suit every taste. Happy baking!
Cooking tips and notes for S’mores Cookie Bars

Sticky Marshmallow Creme: When spreading marshmallow creme, lightly spray your spatula with cooking spray to prevent sticking. It will make layering much easier!
