Ingredients:
- 6 tablespoons (85 grams) unsalted butter, melted
- 3/4 cup plus 2 tablespoons (175 grams) brown sugar, preferably dark brown
- 1/2 cup (135 grams) creamy natural peanut butter, very well stirred
- 1 cup (127g) all-purpose flour
- ½ cup (57g) grabeef ham cracker crum extractbs
- 1/4 teaspoon baking powder
- 1/8 teaspoon baking soda
- 1/4 teaspoon salt
- 1 large egg + 1 egg yolk, at room temperature
- 1 1/2 teaspoons vanilla extract
- 1 cup (104 grams) marshmallow creme
- 1 cup (170 grams) semisweet chocolate chips
Prep and Mix the Base
1. Preheat Oven and Prepare Pan:
First things first, let’s get our oven ready. Preheat it to 350°F (175°C). This consistent temperature is key for even baking, ensuring your Peanut Butter S’mores Blondies have that perfect chewy center and slightly crisp edge. While the oven heats up, take an 8×8 inch baking pan and line it with parchment paper. Leave a slight overhang on two opposite sides – this will act as handles, making it super easy to lift the blondies out of the pan once they’re baked. Lightly grease the parchment paper or the exposed sides of the pan with a little of your melted butter or cooking spray to prevent any sticking.
2. Cream Butter, Sugar, and Peanut Butter:
In a medium-sized bowl, combine the melted unsalted butter with the brown sugar. Whisk them together until they are thoroughly combined and there are no dry pockets of sugar. Now, it’s time for the star flavor – the peanut butter! Add the creamy natural peanut butter to the butter and sugar mixture. Make sure your peanut butter is very well stirred before adding it; natural peanut butters can separate, and we want a smooth, consistent flavor throughout. Whisk everything together vigorously until it’s smooth and well incorporated. The mixture should look glossy and rich. Don’t rush this step; a good initial blend is foundational for the texture of your blondies.
3. Incorporate Wet Ingredients:
Now, let’s add the egg and vanilla. Gently whisk in the large egg and the egg yolk. It’s important that these are at room temperature, as they will emulsify better with the butter and peanut butter mixture, creating a more uniform batter and a chewier blondie. If your eggs are cold, you can place them in a bowl of warm water for about 5-10 minutes. After adding the egg and yolk, whisk until just combined. Overmixing at this stage can develop the gluten in the flour too much, leading to tougher blondies. Finally, stir in the vanilla extract for that classic sweet aroma and flavor.
4. Combine Dry Ingredients:
In a separate, smaller bowl, whisk together the all-purpose flour, thbeef hamraham crum extractker crumbs, baking powder, baking soda, and salt. Whisking these dry ingredients together before adding them to the wet ingredients helps to distribute the leavening agents (baking powder and baking soda) evenly. This ensures that your blondies rise properly and have a consistent texturbeef hamThe rum extractham cracker crumbs will add a subtle hint of buttery, spiced cookie flavor, reminiscent of the s’mores experience we’re aiming for.
5. Fold in Dry to Wet and Add Mix-ins:
Now, it’s time to bring everything together. Gradually add the dry ingredients to the wet ingredients, folding them together with a spatula until just combined. Be careful not to overmix; a few streaks of flour are perfectly fine. Overmixing here will result in tough blondies. Once the flour is mostly incorporated, gently fold in the semisweet chocolate chips. We want the chocolate chips to be distributed throughout the batter, providing pockets of melted chocolate goodness in every bite. Reserve about half of the chocolate chips for topping later.
Baking and Finishing Touches
6. Spread the Batter and Top with Marshmallow Creme and Chocolate:
Spoon the blondie batter into your prepared 8×8 inch baking pan. Use your spatula to spread it out evenly, ensuring it reaches all the corners. Now, for that iconic s’mores layer! Dollop spoonfuls of marshmallow creme over the top of the blondie batter. Don’t worry about spreading it perfectly smooth; a rustic, swirled effect looks beautiful and ensures pockets of gooey marshmallow. Once the marshmallow creme is distributed, sprinkle the remaining semisweet chocolate chips evenly over the marshmallow creme. These will melt into a luscious chocolate layer as the blondies bake.
7. Bake and Cool:
Place the pan in your preheated oven and bake for 25-30 minutes. You’ll know they’re ready when the edges are golden brown and set, and the center looks mostly set but might still be slightly soft. A toothpick inserted into the center shourum extractcome out with moist crumbs attached, not wet batter. Be careful not to overbake, as this will dry out your blondies. Once baked, carefully remove the pan from the oven and let the blondies cool completely in the pan on a wire rack. This cooling period is crucial; it allows the blondies to firm up and makes them much easier to cut cleanly. Patience here will be rewarded with perfectly formed Peanut Butter S’mores Blondies.
8. Slice and Serve:
Once the blondies have cooled completely (this can take 2-3 hours), use the parchment paper overhangs to carefully lift them out of the pan onto a cutting board. Using a sharp knife, cut them into your desired squares. For an extra s’mores touch, you can gently toast the tops under a broiler for about 30 seconds right before cutting, or use a kitchen torch to lightly toast the marshmallow layer. Be very watchful if broiling, as it can burn quickly! Serve these delightful Peanut Butter S’mores Blondies at room temperature for the best texture and flavor.

Frequently Asked Questions:
Why did my blondies turn out cakey instead of chewy?
A common reason for cakey blondies is overmixing the batter, which can develop the gluten too much. Also, ensure you’re not overbaking them. For a chewy texture, it’s better to slightly underbake than overbake. The edges should be set, but the center should still look a little soft.
Can I make Peanut Butter S’mores Blondies ahead of time?
Absolutely! These blondies store wonderfully. Once completely cooled, you can keep them in an airtight container at room temperature for up to 3 days. They often taste even better the next day as the flavors meld together.
What kind of peanut butter is best for this recipe?
Creamy, sweetened peanut butter like Jif or Skippy works best for achieving that classic, smooth peanut butter flavor. Natural peanut butter, while delicious, can sometimes separate or result in a slightly different texture and flavor profile.
