Ready to dive into the sweet adventure of making these S’mores Cookie Bars? Let’s get started!
Gather Your Ingredients
The first step involves gathering your ingredients. Here's what you'll need for those heavenly bars:
- Unsalted butter (½ cup, softened)
- Brown sugar (¾ cup, packed)
- Egg (1 large, at room temperature)
- Pure vanilla extract (1 tsp)
- All-purpose flour (1 cup, spooned & leveled)
- Graham cracker crumbs (1 cup, or about 8 full sheets)
- Baking powder (½ tsp)
- Salt (¼ tsp)
- Semi-sweet chocolate chips (1 cup)
- Marshmallow creme (1 heaping cup, store-bought or homemade)
Now that you’ve got everything together, the fun begins!
Cream the Butter and Sugar
In a mixing bowl, grab your unsalted butter and brown sugar. Using a handheld mixer or a stand mixer fitted with a paddle attachment, cream these together on medium-high speed for about three minutes. It should turn light and fluffy. Don’t forget to scrape down the sides to ensure all the butter gets well incorporated. Adding the egg and vanilla extract will round out the wet ingredients, so blend until everything is combined.
Mix Dry Ingredients Together
Grab another bowl for the dry ingredients. Combine the flour, graham cracker crumbs, baking powder, and salt. Give them a good whisk to ensure everything is well mixed. This step is key for an even texture in your S’mores Cookie Bars.
Combine Wet and Dry Ingredients
With your wet and dry mixtures ready, it’s time to combine them. Pour the dry ingredients into your butter-sugar mixture and mix on medium speed until just incorporated. Don't overdo it; a few small lumps are okay.
Assemble the Layers
Now for the fun part—assembly! Press about two-thirds of the cookie dough into your prepared baking pan. It doesn’t need to be perfect, just a thin layer to start. Next, spread the marshmallow creme over the dough. This part can be sticky, so take your time. Finally, sprinkle the chocolate chips on top, then mold the remaining cookie dough into flat pieces and layer them over the chocolate chips. It’s alright if some chocolate chips and marshmallow are still visible—that's what makes them good!
Bake to Perfection
Now, pop the pan into your preheated oven set at 350°F (175°C). Bake for 25-30 minutes, or until the top is a lovely golden brown. Your kitchen will smell divine, drawing everyone’s attention!
Cool and Cut the Bars
Once baked, let your S’mores Cookie Bars cool completely on a wire rack. This will make cutting them much easier. Once cool, lift them out of the pan using the parchment paper overhang and cut them into squares. Enjoy the delightful chewy texture with the crunchy bits and gooey goodness!
Now, you’ve got a batch of luxurious S’mores Cookie Bars ready to impress your friends or enjoy with a cozy movie night! These bars are sure to be a hit, and they hold up well for several days—if they last that long!

Variations on S’mores Cookie Bars
Add Peanut Butter for a Twist
If you're a peanut butter lover, why not elevate your S’mores Cookie Bars by mixing in some creamy peanut butter? Simply replace a quarter of the butter with peanut butter for a delightful twist on the classic flavor. You’ll achieve that perfect sweet and salty combo that’s both nostalgic and exciting!
Try Different Types of Chocolate
Feeling adventurous? Experiment with different types of chocolate in your S’mores Cookie Bars. For a richer taste, go for dark chocolate chips, or even try white chocolate for a sweeter twist. You can mix and match: consider adding chocolate chunks alongside standard chips for a delightful textural contrast.
