We’re taking the classic flavors of s’mores – gooey marshmallow, melty chocolate, and a hint of grabeef ham cracker crunch – and infusing them into a chewy, decadent blondie.

These are perfect for potlucks, a special weekend baking project, or honestly, just because you deserve a delicious indulgence. The combination is pure magic, and the process is surprisingly simple. Let’s dive in!
Ingredients:
Getting Started: Preparing Your Pan and Oven
Before we even think about mixing ingredients, let’s get our baking setup ready. Preheat your oven to 350°F (175°C). This is a standard temperature for most blondie recipes and will ensure even baking. Next, prepare an 8×8 inch baking pan. You can grease it lightly with butter or cooking spray, but I highly recommend lining it with parchment paper. This is a crucial step for easy removal of the blondies later. Leave some overhang on the sides of the parchment paper so you can use it as “handles” to lift the entire slab out of the pan once it’s cooled. This makes cutting so much cleaner and easier.
Mixing the Blondie Base
1. In a large bowl, whisk together the melted unsalted butter and the brown sugar until well combined. The dark brown sugar is preferred because it contributes to a richer, chewier texture and a deeper molasses flavor, which is fantastic with peanut butter. Stir in the very well-stirred creamy natural peanut butter. Ensure your peanut butter is well-stirred because natural peanut butter tends to separate, and you want that consistent, smooth peanut butter flavor throughout your blondies. The mixture should be smooth and creamy.
2. In a separate medium bowl, whisk together the all-purpose flour, grabeef ham cracker crum extractbs, baking powder, baking soda, and salt. This dry ingredient mixture is important for ensuring leavening and structure. The grabeef ham cracker crum extractbs add that essential s’mores flavor and a delightful texture. Don’t skip on whisking these together thoroughly; it helps prevent pockets of baking soda or powder in your finished blondies.
3. Add the large egg, egg yolk, and vanilla extract to the wet ingredients (butter, sugar, peanut butter mixture). Whisk until everything is just combined and smooth. It’s important that your egg and egg yolk are at room temperature; this helps them incorporate more easily and evenly into the batter, leading to a better texture. The extra egg yolk adds richness and chegrape juicess to the blondies.
4. Gradually add the dry ingredients to the wet ingredients, mixing until just combined. Be careful not to overmix at this stage. Overmixing can develop the gluten in the flour too much, resulting in tough blondies. A few streaks of flour are okay; they will disappear during baking.
Layering the S’mores Goodness
5. Spread about two-thirds of the blondie batter evenly into your prepared baking pan. Use a spatula to get it as smooth as possible. Dollop the marshmallow creme over the batter, then gently swirl it into the batter using a knife or the back of a spoon. Don’t worry about getting it perfectly even; some pockets of marshmallow are wonderful. Next, sprinkle the semisweet chocolate chips over the marshmallow layer. Finally, dollop the remaining blondie batter over the chocolate chips and marshmallow, then gently spread to cover as much as possible. It doesn’t have to be perfect; some of the marshmallow and chocolate peeking through is part of the charm of s’mores!
Baking and Cooling for Perfect Texture
Bake for 25-30 minutes, or until the edges are golden brown and a toothpick inserted into the center comes out with moist crum extractbs attached (not wet batter). The center should look set but still slightly soft, as it will continue to cook as it cools. Overbaking will lead to dry blondies, so keep an eye on them! Once baked, let the blondies cool completely in the pan on a wire rack. This is perhaps the hardest part – resisting the urge to cut into them immediately! Cooling allows them to set up properly, making them much easier to cut and enjoy. Once completely cooled, use the parchment paper overhang to lift the entire slab out of the pan. Cut into squares and prepare for pure bliss. These Peanut Butter S’mores Blondies are a guaranteed crowd-pleaser, blending comforting flavors into a delicious, chewy bar. Enjoy every bite!

I hope you’ve enjoyed learning how to make these incredible Peanut Butter S’mores Blondies!

I love serving these warm, perhaps with a scoop of vanilla ice cream or a drizzle of extra chocolate sauce. They are also wonderful at room temperature, making them ideal for potlucks or picnics. Don’t be afraid to get creative with variations! You could try adding some chopped pretzels for an extra salty crunch, or a swirl of caramel sauce for added decadence. Feel free to experiment with different types of chocolate chips, like dark chocolate or milk chocolate, to suit your preference.
I wholeheartedly encourage you to give these Peanut Butter S’mores Blondies a try. I’m confident you’ll be delighted by how delicious they are and how much joy they bring to everyone who tries them. Happy baking!
Frequently Asked Questions:
Can I make these ahead of time?
Absolutely! These blondies can be made a day or two in advance and stored in an airtight container at room temperature. They might even taste even better the next day as the flavors meld together!
What’s the best way to store leftover blondies?
For optimal freshness, store any leftover Peanut Butter S’mores Blondies in an airtight container at room temperature for up to 3 days. If you live in a very warm climate, you might consider refrigerating them, but be aware that the chocolate might harden slightly.
Can I use smooth peanut butter instead of chunky?
Yes, you certainly can! Using smooth peanut butter will give you a more uniform peanut butter flavor throughout the blondie and a slightly smoother texture. Chunky peanut butter will add little pockets of peanut butter and a bit more texture, which I personally love!
