Ingredients

(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)

6 tablespoons (85 grams) unsalted butter
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
1/2 cup (57g) graham cracker crumbs
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

Directions

Preheat the Oven: Preheat the oven to 350°F (175°C). Line an 8×8-inch metal pan with parchment or foil, leaving an overhang on all sides, then spray with nonstick baking spray.
Melt the Butter: In a large microwave-safe bowl, melt the butter. Once melted, add the brown sugar and peanut butter, stirring until smooth. Set aside to cool.
Mix the Dry Ingredients: In a separate medium bowl, combine the flour, graham cracker crumbs, baking powder, baking soda, and salt. Set aside.
Add Eggs and Vanilla: Whisk the egg and egg yolk into the cooled peanut butter mixture, one at a time, whisking well after each addition. Add the vanilla extract and stir to combine.
Combine Wet and Dry Ingredients: Gradually add the flour mixture to the peanut butter mixture and stir until just combined. The dough will be thick.
Layer the Blondies: Press two-thirds of the dough into the prepared pan, spreading evenly to the edges. Spoon the marshmallow creme around the base layer and spread it out as evenly as possible. It doesn’t have to be perfect! Sprinkle the chocolate chips evenly over the marshmallow layer.
Top the Blondies: Take portions of the remaining dough and flatten them with your hands. Place the flattened dough pieces on top of the marshmallow and chocolate chips, covering about two-thirds of the top.
Bake the Blondies: Bake for 26-28 minutes, or until the center is slightly jiggly, the edges are lightly golden brown, and the marshmallow on top is puffed and lightly golden. Be careful not to overbake to avoid dry blondies.
Cool and Serve: Allow the blondies to cool completely in the pan. Once cooled, cut into squares and serve.

Variations

Add Nuts: If you like a bit of crunch, add chopped peanuts or your favorite nuts into the dough for a different texture.
Use Milk or White Chocolate: If you prefer milk or white chocolate, feel free to swap the semisweet chocolate chips with your choice of chocolate.
S’mores Twist: For an even more authentic s’mores flavor, you can fold in mini marshmallows along with the marshmallow creme and chocolate chips.
Dried Fruit: Add some dried cranberries, cherries, or raisins to balance out the sweetness with a little tartness.

Storage/Reheating

Store any leftover blondies in an airtight container at room temperature for up to 3 days. These blondies can also be refrigerated if you’d like to keep them longer. To enjoy them warm, heat individual pieces in the microwave for a few seconds or in the oven at a low temperature.

FAQs

1. Can I use crunchy peanut butter instead of creamy?

Yes, you can use crunchy peanut butter if you like a little extra texture. Just make sure it’s well stirred, and the dough may be slightly more textured.

2. Can I make these without marshmallow creme?

If you can’t find marshmallow creme, you can substitute with mini marshmallows. Just layer them between the dough, and they’ll melt perfectly during baking.

3. Can I freeze these blondies?

Yes, these blondies freeze well. Once they’ve cooled, wrap them tightly in plastic wrap or place them in an airtight container. They will stay fresh in the freezer for up to 3 months.

4. Can I make these s’mores blondies gluten-free?

You can make these blondies gluten-free by substituting the all-purpose flour with a gluten-free flour blend. Make sure the graham cracker crumbs are also gluten-free.

5. How do I prevent the marshmallow from sinking?

It’s important to add the marshmallow creme between the layers of dough, rather than mixing it into the batter. This will help keep the marshmallow from sinking to the bottom.

6. How do I know when they are done baking?

The blondies should be lightly golden on the edges, with a slight jiggle in the center. The marshmallow should be puffed and golden brown.

7. Can I add more chocolate chips?

Absolutely! If you’re a chocolate lover, feel free to add extra chocolate chips for a richer, more chocolatey flavor.

8. Can I use a different pan size?

You can use a larger pan, but keep in mind the blondies will be thinner. If you use a larger pan, reduce the baking time by a few minutes.

9. Can I use graham cracker crumbs from a box mix?

Yes, store-bought graham cracker crumbs work perfectly if you don’t have the time or inclination to crush your own graham crackers.

10. How should I cut the blondies?

For even squares, let the blondies cool completely in the pan before cutting. Use a sharp knife and clean it between cuts to keep the pieces neat.

Conclusion

Peanut Butter S’mores Blondies are the perfect combination of chewy peanut butter goodness, gooey marshmallow fluff, and decadent chocolate chips.
