Ingredients You'll Need
These simple yet essential ingredients come together to create the perfect texture and flavor that make this Peanut Butter and Jelly Blondies Recipe so memorable.

- All-purpose flour: Provides the base structure, giving the blondies their soft yet sturdy crumb.
- Baking powder: Adds just the right amount of lift for a tender bite without being cakey.
- Salt: Enhances the sweetness and balances the flavors in the blondies.
- Light brown sugar: Adds moisture and a subtle caramel depth, making every bite chewy.
- Unsalted butter: Melted and cooled for richness and a velvety mouthfeel.
- Eggs: Bind all ingredients together and give structure to the blondies.
- Vanilla extract: Infuses warm, aromatic notes that deepen the overall flavor.
- Creamy peanut butter: Blended in the batter for that unmistakable nutty goodness.

How to Make Peanut Butter and Jelly Blondies Recipe
Step 1: Prepare Your Pan and Dry Ingredients
Start strong by preheating your oven to 350°F and preparing an 8x8 inch baking pan. Spraying it and lining it with foil creates the perfect sling for easy removal later—a little tip that makes serving these blondies a breeze. Then, whisk together your flour, baking powder, and salt to ensure an even distribution that guarantees consistent texture in every bite.
Step 2: Mix Butter and Sugar
In a separate bowl, combine the light brown sugar with melted, cooled butter. Whisking these ingredients together until fully combined creates a beautifully smooth and luscious base where the rest of the magic happens. This combination locks in moisture and sweetness that’s absolutely essential for the blondies’ chewy texture.
Step 3: Incorporate Eggs and Flavors
Add your eggs one at a time, whisking after each addition to ensure a smooth, emulsified batter. Follow this with the vanilla extract, bringing a subtle fragrant warmth, and then blend in the creamy peanut butter. This is where the peanutty charm really starts to shine and weave into the batter.
Step 4: Combine Wet and Dry Ingredients
Gently fold the dry ingredients into your wet peanut butter batter using a rubber spatula. The goal is to mix just enough to combine everything without overworking the batter, helping keep those blondies tender and soft instead of dense.
Step 5: Add Swirled Toppings
For the crowning glory, warm the topping peanut butter and jelly just enough to make them easy to drop onto the batter. Drop them in spots across the top, leaving some blondie batter showing. Using the tip of a knife, swirl these together gently. This artistic swirl creates those gorgeous marbled pockets of peanut butter and jelly that make this recipe so special.
Step 6: Bake and Cool
Bake your blondies for 20 to 25 minutes, until the center is set but still tender. Cooling them completely in the pan is key for clean slicing and perfect texture. Use the foil sling to lift the whole slab out, then cut into 9 large or 12 smaller blondies as you please.
How to Serve Peanut Butter and Jelly Blondies Recipe
Garnishes
To elevate your Peanut Butter and Jelly Blondies Recipe, sprinkle chopped peanuts or a dusting of powdered sugar on top. These little touches add texture and a beautiful finish that makes your dessert look as delicious as it tastes.
Side Dishes
Pair your blondies with a scoop of vanilla ice cream or a dollop of whipped cream to contrast the sweet and nutty flavors. Fresh fruit like sliced strawberries or raspberries also complements the jelly, making the whole experience feel balanced and fresh.
Creative Ways to Present
Serving these blondies as bite-sized squares on a pretty platter with colorful napkins makes them perfect for parties or afternoon tea. You can even sandwich two pieces with a little extra jelly and peanut butter in the middle for a fun twist on the classic sandwich idea.
Make Ahead and Storage
Storing Leftovers
Once cooled, keep your blondies tightly wrapped or in an airtight container at room temperature for up to three days. This helps retain their soft texture and rich flavor, allowing you to enjoy them fresh whenever cravings strike.
Freezing
If you want to keep your Peanut Butter and Jelly Blondies Recipe going longer, wrap them well in plastic wrap followed by foil, and freeze for up to two months. Thaw them overnight in the fridge before serving for the best results.
Reheating
For a just-baked feel, warm individual blondies in the microwave for about 10-15 seconds. The peanut butter and jelly will soften up wonderfully, bringing back that gooey goodness you love.
FAQs
Can I use crunchy peanut butter instead of creamy?
Absolutely! Crunchy peanut butter will add a lovely texture contrast, with little bits of peanut throughout the blondies. Just be sure to swirl the topping peanut butter carefully since it might be a bit thicker.
Which jelly flavors work best in this recipe?
Grape, raspberry, and strawberry jellies all pair beautifully with peanut butter in these blondies. Feel free to experiment with your favorite jelly to create your own signature version.
Can I make these blondies gluten-free?
Yes, you can substitute the all-purpose flour with a gluten-free blend designed for baking. Make sure it includes xanthan gum or another binder to keep the blondies from crumbling.
Is it possible to double the recipe?
For sure! Just use a larger pan or two baking pans and adjust the baking time slightly, checking for doneness around the 25-minute mark to avoid overbaking.
Are these blondies suitable for kids?
Definitely. The flavors are familiar and kid-approved, making these blondies a fun treat for lunchboxes, birthday parties, or an after-school snack.

Peanut Butter and Jelly Blondies Recipe
- Total Time: 40 minutes
- Yield: 9 large or 12 small blondies
Description
These Peanut Butter and Jelly Blondies are a delightful twist on the classic PB&J sandwich, baked into rich, chewy blondies with a swirled peanut butter and jelly topping. Perfect for dessert or a sweet snack, they combine creamy peanut butter, sweet jelly, and a soft, buttery crumb in every bite.
Ingredients
Blondies:
- 1 ½ cups all-purpose flour
- 1 teaspoon baking powder
- ½ teaspoon salt
- 1 ½ cups packed light brown sugar
- 8 tablespoons unsalted butter, melted and cooled
- 2 large eggs, room temperature
- 3 teaspoons vanilla extract
- ½ cup creamy peanut butter
Topping:
- ⅓ cup peanut butter
- ⅓ cup grape, raspberry, or strawberry jelly
Instructions
- Prepare the Pan: Preheat your oven to 350°F (175°C). Spray an 8x8-inch baking pan with non-stick spray, then line it with foil leaving two ends extending over the edges of the pan to create a sling. Spray the foil again to prevent sticking and set aside.
- Mix Dry Ingredients: In a medium bowl, whisk together the all-purpose flour, baking powder, and salt. Set this dry mixture aside.
- Combine Sugar and Butter: In a separate large bowl, whisk the packed light brown sugar with the melted and cooled unsalted butter until fully combined and smooth.
- Add Eggs and Flavor: Add the eggs, one at a time, whisking thoroughly after each addition to incorporate completely. Then whisk in the vanilla extract followed by the ½ cup of creamy peanut butter until evenly mixed.
- Fold in Dry Ingredients: Using a rubber spatula, gradually fold the dry flour mixture into the wet ingredients until just combined, being careful not to overmix.
- Spread Batter: Evenly spread the blondie batter into the prepared baking pan, smoothing the top gently.
- Prepare Topping: Microwave ⅓ cup peanut butter in a small bowl and ⅓ cup of your chosen jelly in a separate small bowl for about 10 to 15 seconds until each is smooth and easy to spoon but not runny.
- Add Topping: Drop spoonfuls of warmed peanut butter and jelly evenly across the top of the blondie batter, leaving some batter visible.
- Swirl Topping: Using the tip of a knife, drag it lightly through the peanut butter and jelly on top. Swirl just enough to create an attractive design without mixing the topping too much into the batter.
- Bake: Place the pan in the preheated oven and bake for 20 to 25 minutes, until the center is set and no longer jiggly when gently shaken.
- Cool and Serve: Remove the blondies from the oven and allow them to cool completely in the pan. Once cooled, use the foil sling to lift the blondies out of the pan. Cut into 9 large or 12 small pieces and enjoy!
Notes
- Ensure the peanut butter and jelly are warmed just enough to be spreadable but not too liquidy for easy swirling.
- Use room temperature eggs to help achieve a smooth batter.
- Allowing blondies to cool completely before cutting helps maintain clean slices.
- Customize the topping by using different types of jelly or jam for varied flavor profiles.
- The foil sling simplifies removing the blondies without breaking them.
