Preparation Phase & Tools to Use

Creating your S’mores Cookie Bars is a straightforward affair, but having the right tools on hand ensures a seamless and enjoyable experience. Here are the essentials you’ll need:

  • Mixing Bowls: Large mixing bowls allow you to combine your ingredients thoroughly and effectively without worrying about spills.
  • Electric Mixer: An electric mixer takes the workout out of creaming the butter and sugars, ensuring a light and airy dough.
  • Spatula: Use a sturdy spatula for scraping down the sides of the bowls and folding in ingredients.
  • Baking Pan: A 9×13 inch baking pan is ideal for these cookie bars, allowing for even baking and easy cutting.
  • Parchment Paper: Line your baking pan with parchment for easy removal and cleanup.

Preparation Tips:

  • Preheat your oven early, so it’s ready when you are.
  • Soften your butter adequately—room temperature is key for achieving that creamy, properly blended mixture.
  • Gather all your ingredients beforehand. This makes the cooking process smoother and keeps your focus on baking.

Ingredients for S’mores Cookie Bars

To bring these bars to life, you’ll need the following ingredients:

  • 1 cup Unsalted butter, softened: Gives the bars a rich flavor and a tender texture.
  • 1 cup Brown sugar, packed: Adds sweetness and moisture, resulting in a chewier cookie.
  • 1/2 cup Granulated sugar: Balances the flavors and creates a delightful sweetness.
  • 2 Large eggs: Provide structure and help bind the ingredients.
  • 1 teaspoon Vanilla extract: Infuses warmth and enhances the overall flavor.
  • 2 1/2 cups All-purpose flour: Aids in creating the perfect chewy base.
  • 1 teaspoon Baking soda: Leavens the dough for a light and fluffy texture.
  • 1/2 teaspoon Salt: Brings all the flavors together beautifully.
  • 1 cup Graham cracker crumbs: Introduces that classic s’mores flavor and crunch.
  • 1 cup Chocolate chips: The star ingredient, melting beautifully into every bite.
  • 1 cup Mini marshmallows: Soft, fluffy bites that offer delightful gooeyness.
  • Extra chocolate chips and marshmallows for topping: Take your bars to the next level of indulgence!

Feel free to substitute ingredients as needed. For instance, use coconut oil for a dairy-free version, or swap out the chocolate chips for your favorite nut butter chips for a unique twist.

How to Make S’mores Cookie Bars

Follow these simple, delicious steps to create your S’mores Cookie Bars:

  1. Preheat your oven to 350°F (175°C) and line a 9×13 inch baking pan with parchment paper for easy removal.
  2. Cream the butter and sugars: In a large bowl, use an electric mixer to cream the softened unsalted butter, brown sugar, and granulated sugar until light and fluffy. This should take about 2-3 minutes.
  3. Add eggs and vanilla: Beat in the eggs, one at a time, then mix in the vanilla extract until everything is well combined.
  4. Combine dry ingredients: In a separate bowl, whisk together the all-purpose flour, baking soda, salt, and graham cracker crumbs. Add this mixture to the wet ingredients, mixing until just combined.
  5. Fold in chocolate chips: Gently fold in the chocolate chips and mini marshmallows, ensuring they are evenly distributed throughout the dough.
  6. Spread in the pan: Pour the cookie dough into the prepared baking pan, spreading it evenly. Sprinkle extra chocolate chips and marshmallows on top for added richness and to achieve that gooey s’mores look.
  7. Bake: Pop the pan in the preheated oven and bake for 25-30 minutes or until the edges are golden brown and a toothpick inserted in the center comes out clean.
  8. Cool: Allow the bars to cool in the pan on a wire rack before slicing into squares. This enables the marshmallows and chocolate to set beautifully.

Tip: For ultimate gooeyness, slice them while they are still warm.

Chef’s Notes & Helpful Tips

  • Make-ahead tips: You can prepare the dough in advance and store it in the refrigerator for up to 2 days. When you’re ready to bake, allow it to soften slightly at room temperature before spreading it in the pan.
  • Cooking alternatives: If you have an air fryer, you can bake these bars at 320°F (160°C) for 15-20 minutes or until set. Adjust the timing accordingly based on the size of your air fryer basket.
  • Customization ideas: Switch up the chocolate by using dark chocolate chips or even white chocolate. You could add nuts, dried fruit, or even a swirl of peanut butter for an extra special treat.

Common Mistakes to Avoid

  • Overmixing the dough: Mixing too much can lead to denser bars. Mix just until the dry ingredients are combined.
  • Not measuring the flour correctly: Make sure to spoon the flour into the measuring cup and level it off. Avoid scooping directly from the bag, as this can lead to too much flour.
  • Baking too long: These bars continue to cook slightly after they come out of the oven. Check them a few minutes early to prevent dryness.

What to Serve With S’mores Cookie Bars

These delightful S’mores Cookie Bars pair beautifully with a variety of accompaniments that elevate the experience:

  • Vanilla Ice Cream: A scoop of creamy vanilla ice cream adds richness and balances the sweetness of the bars.
  • Hot Chocolate: A warm cup of hot chocolate makes for the perfect companion, especially on chilly evenings.
  • Fresh Berries: A side of fresh raspberries or strawberries cuts through the richness and adds a refreshing burst of flavor.
  • Caramel Sauce: Drizzle some salted caramel over the top for a decadent twist.
  • Coffee: The deep, rich notes of coffee complement the sweetness of the cookie bars beautifully.
  • Milk: A classic pairing, enjoying these bars with a glass of cold milk is simply blissful.

Storage & Reheating Instructions

Store any leftover S’mores Cookie Bars in an airtight container at room temperature for up to 5 days. If you want to keep them fresh for longer, refrigerate them for up to a week. To freeze, place individual bars in freezer-safe bags or containers. They can last in the freezer for up to 3 months. When ready to enjoy, thaw at room temperature or gently reheat in the microwave for a few seconds until just warm, letting the chocolate soften deliciously.

Hi, I’m Clara!

I'm a food lover and a firm believer that anyone can learn to cook with a little curiosity and courage. My story with food didn’t begin in a tiny apartment with a two-burner stove and a stack of cookbooks from the local library. I was broke and desperate to make something anything that felt like home.
