Ingredients You'll Need
- 1 cup crunchy peanut butter (creamy works too if that's your preference!)
- ¾ cup light brown sugar, packed
- ½ cup unsalted butter, softened to room temperature
- 1 large egg, at room temperature
- 1 teaspoon vanilla extract (I love using pure vanilla for a richer flavor)
- 1 ¾ cups all-purpose flour (you can substitute with a gluten-free blend if needed)
- ¾ teaspoon salt
- ½ teaspoon baking powder
- ¾ cup grape jelly or jam (feel free to experiment with your favorite flavors!)
- ½ cup salted peanuts, coarsely chopped (for that extra crunch)
Step-by-Step Instructions
Preheat the Oven
- First things first, let's get that oven preheating! Set it to 350°F (175°C) so it's nice and toasty by the time we're ready to bake.
- While that's heating up, grab your baking pan - a 9x13 inch pan works perfectly for this recipe. Grease it with a little butter or non-stick spray to ensure those bars come out easily after baking.
Make the Base
- In a mixing bowl, add 1 cup of crunchy peanut butter, ¾ cup of packed light brown sugar, and ½ cup of softened unsalted butter.
- Use a wooden spoon or a hand mixer to mix these together until it's all smooth and creamy. You want to make sure there are no clumps, so take your time here.
- Once it's well combined, crack in 1 large egg (make sure it's at room temperature for better mixing) and pour in 1 teaspoon of vanilla extract. Mix it all together until it's beautifully blended!
Prepare the Dry Ingredients
- In a separate bowl, whisk together 1 ¾ cups of all-purpose flour, ¾ teaspoon of salt, and ½ teaspoon of baking powder. This will help ensure that everything is evenly distributed when we combine it.
- Take a moment to appreciate the simple beauty of flour and sugar together - it's like magic in the making!
Combine the Mixtures
- Now it's time to bring it all together. Gradually add the dry mixture to the peanut butter mixture, stirring gently until just combined. Don't worry if it looks a bit thick - that's perfect!
- Trust your gut here; if it looks a little different than you expected, it's okay! The dough should be somewhat sticky but easily spreadable.
Assemble the Bars
- Take half of the dough and spread it evenly into the bottom of your prepared baking pan. I like to use my fingers to pat it down gently, ensuring it's nice and even.
- Next, layer it with ¾ cup of grape jelly or your favorite jam. Spread it out evenly, but don't worry if it's not perfect - we like a little rustic charm!
- Now, take the remaining dough and drop spoonfuls over the jelly layer. Gently spread it out to cover the jelly completely. Finally, sprinkle ½ cup of coarsely chopped salted peanuts on top for that delicious crunch!
Bake the Bars
- Pop the pan into your preheated oven and let it bake for about 25 minutes. Keep an eye on it, and look for that lovely golden brown color around the edges. You can also use the toothpick test - if it comes out mostly clean (a few crumbs are okay!), they're done!
- Once baked, remove the pan from the oven and let it cool completely before slicing into bars. I know it's hard to wait, but trust me, it's worth it!

Variations
- For a chocolatey twist, add ½ cup of chocolate chips to the dough.
- Try swapping the grape jelly for strawberry or raspberry for a fruity change!
- Make it dairy-free by using coconut oil instead of butter and a plant-based egg substitute.
- For a gluten-free version, use a gluten-free flour blend in place of all-purpose flour.
- Add a sprinkle of cinnamon to the dough for a warm, cozy flavor.
Serving and Storage Tips
Serving
These Peanut Butter and Jelly Bars are best served at room temperature, allowing all those delicious flavors to shine through. You can cut them into squares or rectangles, depending on your preference. They make a perfect treat alongside a glass of cold milk or even a warm cup of tea. For special occasions, feel free to dust them with a little powdered sugar for an extra touch of sweetness!
Storage
To keep your bars fresh and tasty, store them in an airtight container at room temperature for up to a week. If you need to keep them longer, they freeze beautifully! Just wrap them tightly in plastic wrap, then place them in a freezer-safe bag. They'll last in the freezer for up to three months. When you're ready to enjoy them, simply let them thaw at room temperature or pop them in the microwave for a few seconds for that fresh-baked taste again.
Helpful Notes
- If you're out of brown sugar, you can substitute it with granulated sugar, but the bars may be a bit less chewy.
- For nut allergies, try sunflower seed butter instead of peanut butter for a delicious alternative!
- Add in some oats for extra texture and flavor; about ½ cup works great.
- Feel free to reduce the sugar if you prefer a less sweet treat - just keep an eye on the texture.
- For a fun twist, mix in some mini chocolate chips or M&Ms for a colorful touch!
