Ingredients for S’mores Cookie Bars
Here’s what you’ll need to make this delicious S’mores Cookie Bars:
½ cup butter – Go for unsalted butter to control the saltiness of the dough, ensuring your bars are perfectly balanced.

2 teaspoons ground cinnamon – Adds warmth and an extra layer of flavor, making these bars irresistible.
2 teaspoons vanilla extract – Use pure vanilla extract for the best flavor, elevating the sweet notes throughout.
2 large eggs – Helps bind the ingredients together and adds a rich texture.
2 cups all-purpose flour – The base for your cookie dough; sifted flour gives your bars a softer bite.
2 teaspoons baking powder – For that perfect rise and fluffiness, ensuring your bars are soft and chewy.
1 teaspoon sea salt – A pinch of salt brings out all the flavors, enhancing the sweetness of the dough.
1 cup semi-sweet chocolate chips – These are the heart of the dessert, melty and rich in every bite.
12 oz bag large marshmallows, cut in half – These will top your bars, adding that beloved s’mores flavor and texture.
2 milk chocolate candy bars, cut into small pieces – Melts beautifully over the warm marshmallows and adds another layer of chocolatey goodness.
8 graham crackers, broken into small pieces – The classic s’mores crunch that ties it all together, bringing that authentic taste to your dessert.
How to Make S’mores Cookie Bars
Follow these simple steps to prepare this delicious S’mores Cookie Bars:
Step 1: Preheat the Oven
Preheat your oven to 350℉ (180℃) and prepare a 9×13 inch baking pan by lining it with parchment paper, or give it a generous coat of butter or cooking spray. This will help your cookie bars come out easily, preventing any unnecessary wrestling matches with the pan.
Step 2: Melt the Butter
In a large mixing bowl, melt the butter in the microwave until it’s nice and gooey. No one likes a stiff cookie dough, and melting that buttery goodness is the first step to cookies that melt in your mouth.
Step 3: Mix in the Sugars
Add the brown sugar and white sugar to the melted butter, mixing until it’s fully incorporated and creamy. You want a nice, smooth mixture that smells like sweet heaven.
Step 4: Add Flavor and Eggs
Stir in the ground cinnamon, vanilla extract, and eggs until everything is well combined. The warm smell of vanilla and cinnamon will have your taste buds dancing in anticipation.
Step 5: Combine the Dry Ingredients
Gradually mix in the flour, one cup at a time, followed by the baking powder and sea salt. Use a spatula or wooden spoon for this, and don’t forget to scrape down the sides of the bowl for an even mix.
Step 6: Fold in the Chocolate Chips
Now it’s time for the chocolate chips! Gently fold them into your cookie dough, and you will want to taste a little of this heavenly mixture (just a tiny bit; we need enough for the bars!)
Step 7: Bake the Cookie Bars
Transfer the dough into your prepared baking pan, spreading it out evenly. Bake for about 20 minutes until the edges are lightly golden brown, and a toothpick inserted in the center comes out mostly clean. The kitchen will smell divine!
Step 8: Add the Marshmallows
Once you take the pan out of the oven, place the halved marshmallows cut side up across the top of the baked cookie bars. Put it back in the oven for a quick broil for about 2 minutes or just until they turn a lovely golden brown. Watch them closely; no one wants burnt marshmallows!
Step 9: Top It Off
After broiling, remove the cookie bars from the oven and allow them to cool slightly before sprinkling on the chocolate bar bits and graham cracker pieces. This creates that irresistible s’mores assembly everyone loves!
Step 10: Cool and Serve
Let the bars cool completely in the pan before slicing them into generous squares. Share with friends or hoard them for yourself—no judgment here!
Enjoy these S’mores Cookie Bars with a cold glass of milk, and you’ll find every bite transports you back to those warm summer nights by the campfire. They’re perfect for any occasion, and trust me, your friends and family will love you for it!
