Peanut Butter & Jelly Cookie Bars — Do This Next

Now that you have your ingredients and tools ready, let’s get baking! Follow these steps to create your Peanut Butter & Jelly Cookie Bars.
Step 1: Preheat the Oven
Preheat your oven to 350°F (175°C). This ensures that your cookie bars bake evenly.
Step 2: Prepare the Baking Pan
Line a 9×13 inch baking pan with parchment paper, leaving some overhang on the sides for easy removal later. This will help your cookie bars come out cleanly.
Step 3: Mix the Dry Ingredients
In a medium bowl, whisk together the all-purpose flour, baking soda, and salt. Set this mixture aside.
Step 4: Cream the Butters and Sugars
In a large mixing bowl, combine the unsalted butter, creamy peanut butter, brown sugar, and granulated sugar. Use a hand mixer or stand mixer to cream these together until light and fluffy, about 2-3 minutes.
Step 5: Add the Egg and Vanilla
Beat in the egg and vanilla extract to your creamed mixture until fully combined.
Step 6: Combine Wet and Dry Ingredients
Gradually add the dry ingredient mixture to the wet ingredients, mixing until just combined. Be careful not to overmix.
Step 7: Spread the Dough in the Pan
Scoop the cookie dough into the prepared baking pan. Use a spatula to spread it evenly across the bottom.
Step 8: Add the Jelly
Dollop the grape jelly over the cookie dough. Use the spatula to gently spread it out, creating an even layer.
Step 9: Bake
Bake in the preheated oven for 25-30 minutes, or until the edges are golden brown and a toothpick inserted in the center comes out clean.
Step 10: Cool and Slice
Allow the cookie bars to cool in the pan for about 10 minutes. Then, use the parchment paper to lift them out and cool completely on a wire rack. Once cooled, slice into squares and enjoy!
Seasonal Flavor Boosts

Feeling adventurous? Here are some seasonal flavor ideas to elevate your Peanut Butter & Jelly Cookie Bars:
- Use strawberry jelly instead of grape for a classic twist.
- Add chocolate chips to the dough for a rich chocolate-peanut butter combo.
- Mix in chopped nuts for extra crunch and flavor.
- Try honey or maple syrup for a different sweetener option.
Flavor Logic
The beauty of these Peanut Butter & Jelly Cookie Bars lies in their flavor balance. The creamy peanut butter provides a savory depth, while the grape jelly offers a sweet and fruity contrast. This combination not only satisfies your sweet tooth but also evokes warm memories of childhood lunches. The slight saltiness from the peanut butter enhances the sweetness of the jelly, creating a decadent treat that’s hard to resist.
Make Ahead Like a Pro
Want to save time? Here are some tips for making these cookie bars ahead of time:
You can prepare the dough a day in advance. Simply wrap it tightly and refrigerate. When you’re ready to bake, let it sit at room temperature for about 15 minutes before spreading it in the pan and adding the jelly.
These bars can also be baked and stored in an airtight container at room temperature for up to a week. For longer storage, freeze any leftovers. Just wrap them well and they’ll be good for up to three months. Thaw at room temperature when you’re ready to enjoy again!
Top Questions & Answers
Can I use crunchy peanut butter instead of creamy?
Absolutely! Using crunchy peanut butter will add texture and a delightful crunch to your cookie bars, enhancing the overall experience.
What if I don’t have grape jelly?
No worries! You can substitute any fruit jelly or jam of your choice, such as raspberry or strawberry. Just ensure it’s well-stirred for easy spreading.
Can I make these bars gluten-free?
Yes! Simply substitute the all-purpose flour with a gluten-free flour blend. The texture may vary slightly, but they will still be delicious.
How do I know when the cookie bars are done baking?
Look for golden edges and a slightly firm center. A toothpick inserted in the middle should come out clean or with a few moist crumbs. Avoid overbaking to keep them soft and chewy.
