S'mores Bars Recipe with Peanut Butter

In the heartwarming tale of S'mores Cookie Bars recipe with peanut butter, it was my imaginative daughter, Georgia, who crafted this magical recipe. I know it's not a Crockpot Recipe like my Crockpot Peanut Clusters or Apple Pie Dump Cake but I promise this sweet treat is easy to make. And I think next time I just might make it in the Crockpot!

With her bright eyes brimming with wonder and enthusiasm, she selected the finest ingredients – graham cracker crumbs, semi-sweet chocolate chips, peanut butter chips, marshmallow creme, and, of course, rainbow sprinkles. Together, we created this recipe just for her with all her magical imagination! As she scattered the rainbow sprinkles like stardust, the kitchen filled with magic. When we finally tasted our creation, it was not just a sweet treat but a testament to how cooking can create the best memories.

S'mores Bars Ingredients (Full Recipe In Recipe Card)

Before we dive into the step-by-step instructions, let's take a look at the ingredients you'll need to make these mouthwatering s'mores bars. The great thing is that you probably already have most of them in your pantry:

  1. Unsalted Butter: Softened to room temperature, butter adds richness and moisture to the cookie dough.
  2. Brown Sugar: Packed light or dark brown sugar imparts a deep, caramel-like sweetness that complements the other flavors in the bars.
  3. Egg: One large egg, also at room temperature, provides structure and moisture to the dough.
  4. Vanilla Extract: A teaspoon of pure vanilla extract enhances the overall flavor profile of the bars.
  5. All-Purpose Flour: The foundation of the cookie dough, all-purpose flour adds structure and thickness. I use gluten-free flour.
  6. Graham Cracker Crumbs: These are crucial for capturing the signature graham cracker flavor and creating the classic s'mores base. I use gluten-free graham crackers.
  7. Baking Powder: A small amount of baking powder gives the bars a gentle lift and ensures they're not overly dense.
  8. Salt: Just a quarter teaspoon of salt balances the sweetness and enhances the overall flavor.
  9. Chocolate Chips: Both semi-sweet chocolate chips and peanut butter chips are added to the dough for a delightful combination of flavors and textures.
  10. Marshmallow Creme: The hero of the recipe, marshmallow creme provides the gooey, marshmallowy goodness that's synonymous with s'mores.
  11. Rainbow Star Sprinkles (Optional): These are a fun and colorful addition, perfect for adding a touch of whimsy to your bars.

Step-by-Step Instructions for S'mores Bars Recipe with Peanut Butter:

Now that we've covered why you'll love this s'mores bar recipe and the ingredients you'll need, let's get into the nitty-gritty of making these irresistible treats.

  1. Preheat your oven to 350°F (175°C) and line an 8x8-inch (20x20 cm) square baking pan with parchment paper, leaving some overhang on the sides for easy removal.
  2. In a large mixing bowl, cream the softened butter and brown sugar together until smooth and creamy.
  3. Add the egg and vanilla extract to the butter-sugar mixture and beat until well combined.
  4. In a separate bowl, whisk together the all-purpose flour, graham cracker crumbs, baking powder, and salt.
  5. Gradually add the dry ingredients to the wet ingredients and mix until a thick cookie dough forms.
  6. Press half of the cookie dough into the bottom of the prepared baking pan, creating an even layer.
  7. Fold in the semi-sweet chocolate chips, peanut butter chips, and sprinkles. The dough should be studded with these delightful morsels.
  8. Spread the marshmallow creme over the cookie dough layer. This might be a bit sticky, so using an offset spatula or greased hands can help.
  9. Take the remaining cookie dough and crumble it over the marshmallow creme. This creates a rustic, textured topping.
  10. If desired, sprinkle rainbow sprinkles over the top for a pop of color.
  11. Bake the bars in the preheated oven for approximately 25-30 minutes, or until the edges are golden brown and the center is set. Be sure to keep a close eye on them during the last few minutes to avoid over-baking.
  12. Allow the S'mores Cookie Bars to cool in the pan for at least 30 minutes before using the parchment paper overhang to lift them out.
  13. Once the bars have completely cooled, slice them into squares and indulge in the gooey, delightful goodness.

FAQs About S'mores Bars with Peanut Butter

  1. Can I use other types of cookies?

Yes, you can get creative with the crust. While graham crackers are the traditional choice, you can experiment with other cookies, such as Oreos, to create a unique flavor profile.

  1. Can I make these bars in advance?

Absolutely! S'mores bars can be made in advance and stored in an airtight container at room temperature for a few days. You can also refrigerate them to extend their shelf life.

  1. How do I prevent the marshmallows from sticking to the knife when slicing?

To prevent the marshmallows from sticking to the knife, you can lightly grease the knife with non-stick cooking spray or dip it in hot water before each slice. This will make the cutting process much smoother.

  1. Can I make these s'mores bars gluten-free?

Yes, you can make gluten-free s'mores bars by using gluten-free graham crackers and gluten-free flour which is what I use, or a suitable substitute for the crust. Be sure to check that all your other ingredients are also gluten-free.
