Ingredients You’ll Need

You only need a handful of simple ingredients for these bars, but each one plays a key role in creating the perfect balance of creamy, sweet, and chewy textures. From the velvety peanut butter that infuses every bite with richness, to the fruity brightness of strawberry jam, these ingredients come together beautifully.

• Unsalted butter: Provides a luxurious, tender crumb and helps keep the bars moist.
• Sugar: Adds sweetness and helps create that light and fluffy texture when creamed with butter.
• Pure vanilla extract: Enhances the overall flavor with a warm, aromatic note.
• Large eggs: Bind the ingredients together while adding richness.
• Creamy peanut butter: The star ingredient that delivers that unmistakable nutty flavor and creamy texture.
• Flour: Gives structure to the bars, balancing softness and chewiness.
• Baking powder: Provides just enough lift so the bars aren’t dense.
• Strawberry jam: Adds sweet, fruity bursts and beautifully contrasts the peanut butter’s richness.

How to Make Peanut Butter and Jelly Bars

Step 1: Prepare Your Pan and Preheat

Start by preheating your oven to 350°F (175°C). Line a 9×13-inch baking dish with parchment paper, leaving enough overhang on the sides so you can easily lift the bars out after baking. This little prep step ensures cleanup is a breeze and your bars come out perfectly shaped every time.

Step 2: Cream the Butter, Peanut Butter, and Sugar

Use a mixer to cream the softened unsalted butter, creamy peanut butter, and sugar until the mixture becomes light and fluffy—this usually takes about 3 to 4 minutes. This step is crucial because it introduces air that makes the bars wonderfully tender and soft.

Step 3: Add Eggs and Vanilla

Next, incorporate the eggs one at a time, beating well after each addition so everything blends smoothly. Then, stir in the vanilla extract for that warm, inviting fragrance that hints at the deliciousness to come.

Step 4: Mix Dry Ingredients and Combine

In a separate bowl, whisk together the flour and baking powder, then gradually add this dry mix to your wet peanut butter mixture, stirring just until a dough forms. Overmixing can make the bars tough, so aim for a just-combined, slightly sticky dough.

Step 5: Layer the Dough and Jam

Press about two-thirds of the dough evenly into your prepared pan to create the sturdy base layer. Spread the strawberry jam evenly on top, leaving a small border around edges to prevent spillover. Then crumble the remaining dough over the jam for a rustic, textured top layer that adds delightful bite.

Step 6: Bake Until Golden Brown

Bake in your preheated oven for 30 to 35 minutes, or until the top turns a lovely light golden brown and the jam looks bubbly. Keep an eye on it so you don’t over-brown the crust. Once done, allow the bars to cool completely in the pan before lifting out and slicing.

How to Serve Peanut Butter and Jelly Bars

Garnishes

These bars are wonderful as-is, but if you want to elevate them, try a light dusting of powdered sugar over the top for a pretty, sweet finish. Fresh strawberry slices or a small dollop of whipped cream on the side can also add a refreshing contrast to the rich peanut butter flavor.

Side Dishes

Pair these bars with a cold glass of milk or a cup of hot tea for a cozy snack break. For a brunch spread, they complement fresh fruit salads or yogurt parfaits beautifully, offering a sweet anchor to more refreshing dishes.

Creative Ways to Present

For gatherings, cut your Peanut Butter and Jelly Bars into bite-sized squares and serve them on a pretty platter with toothpicks for easy snacking. You can also sandwich a scoop of vanilla ice cream between two bars to create decadent mini ice cream sandwiches — a real crowd-pleaser!

Make Ahead and Storage

Storing Leftovers

Leftover bars keep nicely stored in an airtight container at room temperature for up to 3 days. For longer freshness, pop them in the refrigerator, where they’ll last for about a week without losing their delightful texture.

Freezing

These bars freeze wonderfully, making them great for meal prep or future cravings. Wrap them tightly in plastic wrap and place in a freezer-safe container for up to 2 months. Thaw overnight in the fridge for the best texture and flavor.

Reheating

If you like your bars warm, reheat individual pieces in the microwave for about 15 seconds, or pop them in a toaster oven for a few minutes to get that fresh-baked feel again. Just avoid overheating to keep them from drying out.

FAQs

Can I use a different flavor of jam in the Peanut Butter and Jelly Bars?

Absolutely! Feel free to swap in your favorite jam or preserves—raspberry, grape, or apricot all work beautifully and offer fresh taste variations.

Is it possible to make these bars gluten-free?

Yes, you can substitute the all-purpose flour with a gluten-free blend, but you may need to tweak the amount slightly. Using almond or coconut flour is also an option, but keep in mind these may alter the texture a bit.

Can I replace peanut butter with another nut butter?

Definitely! Almond butter, cashew butter, or even sunflower seed butter can be swapped in for a unique twist or to accommodate allergies without losing that nutty richness.

How do I know when the bars are fully baked?

You’re looking for a light golden brown on top and bubbly jam edges. The bars should feel set and spring back slightly when touched. Using a toothpick in the dough (not the jam) can help confirm doneness—it should come out with just a few moist crumbs.

Can I make these bars vegan?

With a few adjustments, yes! Substitute the butter with a plant-based alternative and use flax or chia eggs instead of regular eggs. Just be mindful these swaps may slightly alter texture and flavor.

Final Thoughts

Peanut Butter and Jelly Bars are a nostalgic, crowd-pleasing treat that’s easy to make, incredibly satisfying, and endlessly versatile. Whether you’re baking for family, friends, or just treating yourself, these bars bring all the joy of a classic sandwich with a delicious twist.
