How to Save and Reheat S’mores Bars

  • Seal s'mores cookie bars in an airtight container, placing parchment paper between layers to prevent sticking. They'll stay fresh for up to 5 days in the refrigerator.
  • Wrap individual bars tightly in plastic wrap, then place in a freezer-safe container. Freeze for up to 3 months, maintaining their delicious flavor and texture.
  • Store in a covered container away from direct sunlight and heat. Consume within a week for optimal taste and freshness.
  • Warm refrigerated or frozen bars in the microwave for 10-15 seconds, or in a preheated oven at 300F for 5-7 minutes until slightly soft and gooey.

Treats and Drinks to Pair with S’mores Bars

  • Pair Craft Cocktails: Mix a marshmallow-infused vodka martini with a graham cracker rim, highlighting the s'mores bar's classic flavors and adding a sophisticated adult twist.
  • Create Beverage Harmony: Serve cold milk or creamy chocolate milk alongside these bars, delivering a nostalgic childhood comfort that perfectly complements the rich, sweet dessert.
  • Match Dessert Wines: Select a sweet port or moscato wine that echoes the cookie's caramelized sugar notes and provides a luxurious counterpoint to the gooey marshmallow and chocolate layers.
  • Enhance Coffee Experience: Brew a robust espresso or dark roast coffee, whose bitter undertones will beautifully balance the s'mores bar's intense sweetness and create a delightful flavor contrast.
  • Gluten-Free S'mores Cookie Bars: Replace wheat flour with a gluten-free blend and use gluten-free graham cracker crumbs to create a celiac-friendly version that maintains the classic flavor profile.
  • Vegan S'mores Cookie Bars: Swap butter with coconut oil, use a flax egg replacement, select dairy-free chocolate chips, and utilize vegan marshmallow creme to craft a plant-based alternative.
  • Reduced Sugar S'mores Cookie Bars: Substitute brown sugar with coconut sugar or monk fruit sweetener, use dark chocolate chips with higher cocoa content, and incorporate almond flour for a lower-sugar option.
  • Nutty S'mores Cookie Bars: Add chopped almonds or pecans into the dough mixture and sprinkle additional nuts between layers for extra crunch and rich, toasted flavor complexity.

FAQs

  • Are graham crackers essential for this recipe?

Graham cracker crumbs provide a signature s’mores flavor and texture. If you don’t have them, substitute with ground digestive biscuits or crushed vanilla cookies.

  • Can I use different types of chocolate?

Absolutely! While semi-sweet chocolate chips work best, you can experiment with milk chocolate or dark chocolate chips for varied flavor profiles. Just ensure they’re evenly distributed across the marshmallow layer.

  • How do I prevent the marshmallow creme from sticking to my spatula?

Lightly grease your spatula or spray it with non-stick cooking spray before spreading the marshmallow creme. This trick helps reduce sticking and makes spreading much easier.

  • What if my dough is too sticky to handle?

Chill the dough in the refrigerator for 15-20 minutes before pressing it into the pan. This will make it firmer and easier to manipulate without sticking to your hands.

  • Combine the classic campfire treat with a cookie bar format, delivering a mouthwatering blend of graham cracker, marshmallow, and chocolate in every single bite.
  • Create a crowd-pleasing treat that appeals to both kids and adults, perfect for gatherings, potlucks, or a sweet weekend family dessert that everyone will love.
  • Prepare these bars in advance and store them easily at room temperature, making them an ideal dessert for busy households or unexpected sweet cravings.

Ingredients for Gooey S’mores Bars

Base Ingredients:
  • Butter: A rich, creamy foundation that adds softness and flavor to the cookie bars.
  • Brown Sugar: Provides deep sweetness and helps create a moist, chewy texture.
  • Egg: Binds the ingredients together and adds structure to the cookie dough.
  • Vanilla Extract: Enhances the overall flavor with its warm, sweet aroma.
Dry Ingredients:
  • Flour: The main structural component that gives the cookie bars their base.
  • Graham Cracker Crumbs: Adds a classic s'mores flavor and unique texture to the dough.
  • Baking Powder: Helps the cookie bars rise and become light and fluffy.
  • Salt: Balances the sweetness and brings out the other flavors in the recipe.
Topping Ingredients:
  • Marshmallow Creme: Creates the gooey, classic s'mores-like layer in the middle of the bars.
  • Semi-Sweet Chocolate Chips: Provides rich chocolate flavor and melty texture throughout the dessert.

Step 1: Preheat and Prepare the Oven

Set your oven to a warm 350F (177C).

Line an 8-inch or 9-inch square baking pan with parchment paper, letting the edges hang over for easy removal later.

Step 2: Create the Butter Mixture

In a large mixing bowl, cream softened butter and brown sugar using a handheld or stand mixer.

Beat on medium-high speed for about 2 minutes until fluffy and well combined.

Step 3: Incorporate Wet Ingredients

Add:
  • Egg
  • Vanilla extract

Beat until blended, scraping down the bowl’s sides to ensure everything mixes thoroughly.

Step 4: Blend Dry Ingredients

In a separate bowl, whisk together:
  • All-purpose flour
  • Graham cracker crumbs
  • Baking powder
  • Salt

Ensure all dry ingredients are evenly distributed.

Step 5: Combine Mixtures

Fold dry ingredients into wet mixture, beating on medium speed until just combined.

The dough should have a slight graham cracker texture.

Step 6: Create the Base Layer

Press two-thirds of the dough into the prepared pan, creating an even bottom layer.

Don’t worry about sticky fingers – it’s part of the fun!

Step 7: Add Marshmallow Layer

Spread marshmallow creme evenly over the dough.

Work carefully to achieve a smooth, consistent layer.

Step 8: Sprinkle Chocolate

Distribute semi-sweet chocolate chips across the marshmallow layer, ensuring even coverage for maximum chocolate enjoyment.

Step 9: Top with Remaining Dough

Flatten remaining dough and layer over the chocolate chips.

It’s okay if some chocolate or marshmallow peeks through.

Step 10: Bake to Perfection

Bake in the preheated oven for 25-30 minutes until the top turns light golden brown.

Your kitchen will fill with an irresistible aroma.

Step 11: Cool Down

Remove from oven and let the pan cool completely on a wire rack.

Patience is key for perfect cutting.

Step 12: Serve and Enjoy

Lift bars out using parchment paper overhang.
