Preparing the Blondie Base
1. Melt the Butter and Sugar: Begin extract by preheating your oven to 350°F (175°C). Line an 8×8 inch baking pan with parchment paper, leaving an overhang on the sides to easily lift the blondies out later. In a medium microwave-safe bowl or a saucepan over low heat, melt the 6 tablespoons of unsalted butter. Once melted, whisk in the 3/4 cup plus 2 tablespoons of brown sugar until well combined. Don’t worry if it looks a little grainy; we’re going for a rich, caramelized flavor base. Next, add the 1/2 cup of creamy natural peanut butter to the butter and sugar mixture. It’s crucial to use natural peanut butter here and to give it a really good stir before measuring, as natural varieties tend to separate. Stir everything together until you have a smooth, glossy, and fragrant mixture. The aroma at this stage is already incredible!
2. Combine Dry Ingredients: In a separate medium bowl, whisk together the 1 cup of all-purpose flour, 1/2 cup of grabeef ham cracker crum extractbs (these add a delightful subtle crunch and s’mores essence), 1/4 teaspoon baking powder, 1/8 teaspoon baking soda, and 1/4 teaspoon salt. Whisking these dry ingredients ensures that the leavening agents and salt are evenly distributed, which is key for consistent texture and rise in your blondies. Make sure there are no lumps of flour.
3. Incorporate Wet and Dry: To the warm peanut butter, sugar, and butter mixture, add the 1 large egg and 1 egg yolk. It’s important that your eggs are at room temperature; this helps them emulsify more easily into the batter, preventing a greasy texture and ensuring a cohesive mixture. Whisk in the 1 1/2 teaspoons of vanilla extract. Now, 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. Stop mixing as soon as you no longer see streaks of dry flour. The batter will be thick and luscious.
Assembling the S’mores Magic
4. Layering the Goodness: Spoon about two-thirds of the blondie batter into your prepared baking pan. Use a spatula or the back of a spoon to spread it as evenly as possible across the bottom. This forms your delicious blondie foundation. Next, dollop spoonfuls of the 1 cup of marshmallow creme over this first layer of batter. Don’t try to spread it perfectly; rough dollops will create lovely pockets of gooey marshmallow throughout the blondies. Sprinkle half of the 1 cup of semisweet chocolate chips over the marshmallow creme. These will melt into glorious puddles of chocolatey goodness as the blondies bake.
5. Adding the Final Layers and Baking: Gently spread the remaining one-third of the blondie batter over the marshmallow and chocolate chips. Try to cover as much of the marshmallow as you can without mixing it too vigorously into the batter. Finally, scatter the remaining semisweet chocolate chips over the top. This ensures that you get plenty of melty chocolate in every bite. Now, carefully place the pan into your preheated oven and bake for 25-30 minutes, or until the edges are set and golden brown, and the center is still slightly soft and gooey. A toothpick inserted near the center should come out with moist crum extractbs, not wet batter. Overbaking will lead to dry blondies, so keep an eye on them in the last few minutes.
6. Cooling and Enjoying: Once baked, remove the blondies from the oven and let them cool completely in the pan on a wire rack. This is perhaps the hardest part, but it’s essential for the blondies to set properly. Resist the urge to cut into them while they’re hot; the gooey centers will just ooze out. Once completely cooled, use the parchment paper overhang to lift the entire block of blondies out of the pan. Cut them into squares or rectangles, and prepare for pure bliss. These Peanut Butter S’mores Blondies are best enjoyed at room temperature, allowing all those incredible flavors to meld and shine. They store well in an airtight container at room temperature for a few days, though I doubt they’ll last that long!

Conclusion:
I hope you’re as excited to bake these Peanut Butter S’mores Blondies as I am to eat them!

The gooey marshmallow swirls, rich peanut butter pockets, and hints of chocolate create a symphony of flavors and textures that are simply irresistible.

Looking for ways to personalize these delightful treats? Try adding some chopped pretzels for a salty crunch, or a sprinkle of sea salt on top before baking to enhance the sweetness. For a dairy-free option, use a good quality vegan peanut butter and vegan marshmallows. Don’t be afraid to get creative and make these Peanut Butter S’mores Blondies your own! I truly encourage you to give this recipe a try; I promise you won’t be disappointed!
Frequently Asked Questions:
How do I store Peanut Butter S’mores Blondies?
You can store these blondies in an airtight container at room temperature for up to 3 days. If it’s particularly warm, you might consider refrigerating them, although they can firm up a bit. They reheat beautifully in a microwave for about 10-15 seconds for that fresh-baked gooeyness.
Can I freeze these blondies?
Yes, absolutely! Once cooled completely, you can wrap individual blondies tightly in plastic wrap, then place them in a freezer-safe bag or container. They will keep well in the freezer for up to 2-3 months. Thaw them overnight at room temperature or gently warm them in the oven or microwave.
My marshmallows melted into a messy puddle, is this normal?
A little melting and spreading of the marshmallows is completely normal and part of the charm of s’mores! However, if you find they’re completely disappearing, you might try gently pressing them into the batter rather than just dropping them. You can also add a few extra marshmallow pieces on top during the last 5 minutes of baking to ensure you get those signature gooey pockets.
