Ingredients for Peanut Butter & Jelly Bars

Peanut Butter Dough

1 cup creamy peanut butter

½ cup unsalted butter, softened
¾ cup brown sugar
¼ cup granulated sugar

1 large egg
1 teaspoon vanilla extract
1½ cups all-purpose flour

½ teaspoon baking powder
¼ teaspoon salt

Jelly Layer

¾ cup fruit jam or preserves (strawberry, raspberry, or grape)

Optional Toppings

Chopped peanuts
Powdered sugar for dusting
White chocolate drizzle

Choosing the Best Jelly

The type of jam you choose can completely change the flavor of your bars.

Popular options include:

Strawberry Jam – Sweet and fruity

Raspberry Jam – Slightly tart and vibrant
Grape Jelly – Classic peanut butter pairing

You can also experiment with apricot or blueberry preserves for unique flavors.

Step-by-Step Instructions

1. Preheat the Oven

Preheat your oven to 350°F (175°C).

Line a 9×9-inch baking pan with parchment paper or lightly grease it.

2. Cream the Butter and Sugars

In a large mixing bowl, beat together:

Butter
Peanut butter
Brown sugar

Granulated sugar

Mix until the mixture becomes light and creamy.

3. Add Egg and Vanilla

Beat in the egg and vanilla extract until fully combined.

This helps create a smooth dough and adds flavor.

4. Mix the Dry Ingredients

In a separate bowl, whisk together:

Flour

Baking powder
Salt

Gradually add this mixture to the peanut butter mixture and stir until a soft dough forms.

5. Press the Base Layer

Press about two-thirds of the dough evenly into the bottom of the prepared pan.

Use a spatula or your hands to create an even layer.

6. Add the Jelly Layer

Spread the jam evenly over the peanut butter base.

Make sure to leave a small border around the edges to prevent spilling during baking.

7. Add the Crumble Topping

Take the remaining dough and crumble it over the jelly layer.

The topping doesn’t need to fully cover the jam—small gaps create a beautiful rustic look.

8. Bake the Bars

Bake for 25–30 minutes, or until the top becomes golden brown and the edges are set.

The jam may bubble slightly, which is normal.

9. Cool Before Cutting

Allow the bars to cool completely in the pan before slicing.

This helps them set properly and prevents crumbling.

Tips for Perfect Peanut Butter & Jelly Bars

Use Creamy Peanut Butter

Natural peanut butter can separate and affect the texture, so regular creamy peanut butter works best.

Don’t Overbake

Overbaking can make the bars dry. Remove them once the edges turn golden.

Chill Before Cutting

If the bars feel soft, refrigerate them for 30 minutes before slicing.

Line the Pan with Parchment

This makes it easy to lift the bars out for clean slicing.

Delicious Variations

1. Chocolate PB&J Bars

Add ½ cup chocolate chips to the dough.

2. Crunchy Peanut Butter Bars

Use crunchy peanut butter for added texture.

3. Mixed Berry Bars

Use mixed berry jam for a colorful flavor blend.

4. Almond Butter & Jelly Bars

Replace peanut butter with almond butter for a slightly different taste.
