Ingredients
To create these delicious Peanut Butter and Jelly Bars, gather the following ingredients:
For the Base
- 1 cup unsalted butter, softened
- 1 ½ cups sugar
- 1 teaspoon pure vanilla extract
- 2 large eggs, room temperature
- 2 cups creamy peanut butter
- 3 cups flour
- 1 teaspoon baking powder
For the Topping
- 2 cups strawberry jam
How to Make Peanut Butter and Jelly Bars
Step 1: Preheat the Oven
Preheat your oven to 350°F (175°C) while you prepare your ingredients. Line a 9×13-inch baking dish with parchment paper, ensuring there is an overhang for easy removal later.
Step 2: Cream Together Ingredients
In a mixing bowl, combine the softened butter, creamy peanut butter, and sugar. Using an electric mixer or whisk, cream them together until the mixture is light and fluffy—this should take about 3-4 minutes.
Step 3: Add Eggs and Vanilla
Add the eggs one at a time to the creamed mixture. Mix well after each addition. Once all eggs are incorporated, stir in the pure vanilla extract.
Step 4: Combine Dry Ingredients
In a separate bowl, whisk together the flour and baking powder. Gradually mix this dry ingredient combination into your wet ingredients until a dough forms.
Step 5: Form the Base Layer
Press about two-thirds of the dough evenly into the prepared baking dish to create the base layer for your bars.
Step 6: Spread Strawberry Jam
Carefully spread the strawberry jam over the base layer of dough. Make sure to leave some space around the edges.
Step 7: Crumble Remaining Dough
Take the remaining dough that you set aside earlier and crumble it over the jam layer. This will give your bars a textured top that adds visual appeal.
Step 8: Bake
Place your dish in the preheated oven. Bake for about 30-35 minutes or until the top is light golden brown.
Step 9: Cool and Cut
Once baked, remove from oven and allow to cool completely in the pan. Use the parchment paper overhang to lift out the cooled bars before cutting them into squares or rectangles for serving.
