These Peanut Butter S’mores Bars combine classic campfire flavors into a deliciously chewy, gooey treat. With a buttery peanut butter cookie base, crunchy graham cracker crumbs, melted chocolate chips, and a sweet marshmallow crème topping, these bars bring the nostalgic taste of s’mores indoors without the need for a campfire.

  • Total Time: 45 minutes
  • Yield: 9-12 bars

Ingredients

Cookie Base

  • 1/2 cup butter (1 stick), room temperature
  • 1/4 cup peanut butter
  • 1/4 cup brown sugar
  • 1/2 cup white sugar
  • 1 large egg
  • 1 teaspoon vanilla extract
  • 1 1/3 cups all-purpose flour, spooned and leveled
  • 3/4 cup graham cracker crumbs (about 6 full sheets)
  • 1 teaspoon baking powder
  • 1/4 teaspoon salt

Filling and Topping

  • 1/3 cup peanut butter
  • 1 1/2 cups milk, semi-sweet, or dark chocolate chips
  • 7 ounces marshmallow crème (1 jar)

Instructions

  1. Prepare the Cookie Base: Preheat your oven to 350°F (175°C). In a large mixing bowl, cream together the 1/2 cup of butter, 1/4 cup peanut butter, brown sugar, and white sugar until smooth and fluffy. Add the egg and vanilla extract and mix well.
  2. Mix Dry Ingredients: In a separate bowl, whisk together the all-purpose flour, graham cracker crumbs, baking powder, and salt. Gradually add these dry ingredients to the wet ingredients, mixing until just combined to form a dough.
  3. Form the Base Layer: Press two-thirds of the dough evenly into the bottom of a greased or parchment-lined 9×9 inch baking pan to form the base layer. Make sure the surface is compact and level.
  4. Add Peanut Butter Layer: Spread the 1/3 cup peanut butter evenly over the base layer to create a smooth peanut butter layer.
  5. Top with Chocolate and Marshmallow: Sprinkle the 1 1/2 cups chocolate chips evenly over the peanut butter layer, then dollop the marshmallow crème over the chocolate chips. Use a spatula or knife to gently swirl the marshmallow crème to cover the chocolate chips partially.
  6. Finish with Remaining Dough: Crumble the remaining one-third of the dough over the marshmallow and chocolate layer, distributing it evenly to top the bars.
  7. Bake: Place the pan in the preheated oven and bake for about 25-30 minutes, or until the top is golden brown and the edges are set.
  8. Cool and Serve: Remove the bars from the oven and let them cool completely in the pan on a wire rack. Once cooled, cut into squares and serve.

Notes

  • Ensure butter is at room temperature for easier mixing and better texture.
  • Use real marshmallow crème for the best authentic s’mores flavor; it can be found in most grocery stores near peanut butter or baking supplies.
  • Press the base layer firmly to avoid crumbling when slicing.
  • Store leftovers in an airtight container at room temperature for up to 4 days or refrigerate to keep longer.
  • For a nuttier texture, consider adding chopped peanuts or substituting crunchy peanut butter.
