A deliciously rich and chewy dessert combining peanut butter and jelly in a soft, blondie-style bar – a fun twist on a classic favorite!
These PB&J Blondies are the perfect fusion of two classic childhood favorites – peanut butter and jelly – in a soft, chewy bar form. I decided to make them because I wanted to create a dessert that’s both nostalgic and indulgent.
The peanut butter base is rich and flavorful, while the swirl of jelly adds a sweet, fruity touch that pairs perfectly with the peanut butter. My family loves these blondies because they’re easy to make, portable, and packed with flavor. Whether it’s for a snack, a potluck, or a sweet treat for the family, these blondies are always a crowd-pleaser!
Questions I Often Get Asked About This Recipe
Q: Can I use a different type of nut butter?
A: Absolutely! You can substitute the peanut butter with almond butter, cashew butter, or any nut butter you prefer. Just be aware that it may slightly alter the flavor.
Q: Can I use a different type of jelly or jam?
A: Yes! You can use your favorite jelly or jam – strawberry, grape, raspberry, or even apricot would all work wonderfully in this recipe.
Q: Can I make these blondies ahead of time?
A: Yes! You can make these blondies a day or two ahead of time. Store them in an airtight container at room temperature, and they’ll stay fresh.
Q: How do I make these blondies extra gooey?
A: For a gooier texture, slightly underbake the blondies (check with a toothpick – it should come out with just a few moist crumbs). You can also increase the amount of peanut butter for a more fudgy consistency.
Q: How long do PB&J Blondies last?
A: They’ll last about 3-4 days at room temperature or up to a week in the refrigerator. You can also freeze them for up to 3 months.
What You Need to Make PB&J Blondies
For the Blondie Base:
- 1 cup peanut butter (creamy or chunky)
- 1/2 cup unsalted butter, softened
- 1 cup brown sugar, packed
- 2 large eggs
- 1 teaspoon vanilla extract
- 1 1/2 cups all-purpose flour
- 1/2 teaspoon baking powder
- 1/4 teaspoon salt
For the Jelly Swirl:
- 1/2 cup your favorite jelly or jam (strawberry, grape, or raspberry works great)
How to Make PB&J Blondies
1. Preheat the oven:
Preheat your oven to 350°F (175°C). Grease and line an 8×8-inch baking pan with parchment paper, leaving a bit of overhang for easy removal.
2. Prepare the blondie batter:
In a large mixing bowl, cream together the peanut butter, softened butter, and brown sugar until light and fluffy. Beat in the eggs and vanilla extract until smooth.
3. Mix in the dry ingredients:
In a separate bowl, whisk together the flour, baking powder, and salt. Gradually add the dry ingredients to the peanut butter mixture, mixing until just combined.
4. Spread the batter in the pan:
Spread the blondie batter evenly in the prepared pan. It will be a thick batter, so use a spatula to smooth it out.
5. Add the jelly swirl:
Drop spoonfuls of your favorite jelly or jam over the batter. Use a knife or skewer to gently swirl the jelly into the batter, creating a marbled effect.
6. Bake the blondies:
Bake for 25-30 minutes, or until a toothpick inserted into the center comes out clean with just a few moist crumbs. The top should be lightly golden.
7. Cool and slice:
Allow the blondies to cool in the pan for 10 minutes, then lift them out using the parchment paper and transfer to a wire rack to cool completely. Once cooled, slice them into squares and enjoy!
Tips
- For a more intense peanut butter flavor: Add a tablespoon of peanut butter powder to the batter.
- Make it extra festive: Sprinkle chopped peanuts on top before baking for an extra crunch and peanutty taste.
- For a twist: Try mixing the jelly and peanut butter into the batter for a more uniform flavor throughout the blondies.
