Peanut Butter Bars Recipe
Lunch Lady Peanut Butter Bars are a nostalgic favorite that tastes exactly like the classic school cafeteria dessert we all remember. This recipe features a thick, chewy layer of sweet peanut butter dough made with crushed graham crackers, topped generously with smooth chocolate frosting. It is a simple, no-bake treat that brings back fond memories and feeds a large crowd effortlessly.
Ingredients
Peanut Butter Layer
- 1 cup unsalted butter melted
- 1 cup creamy peanut butter
- 2 teaspoons vanilla extract
- ½ teaspoon salt
- 4 cups powdered sugar
- 2 cups graham cracker crumbs
Chocolate Topping
- 2 cups semi-sweet chocolate chips
- ¼ cup creamy peanut butter
Instructions
- Line a 9×13-inch baking dish with parchment paper, leaving an overhang. Lightly spray with nonstick spray.
- In a large bowl, stir together melted butter and 1 cup peanut butter until smooth. Mix in vanilla and salt.
- Add powdered sugar and graham cracker crumbs. Stir until fully combined and thick like soft dough.
- Press the mixture evenly into the prepared pan. Press firmly for the best texture and clean slices.
- In a microwave-safe bowl, combine chocolate chips and ¼ cup peanut butter. Microwave in 20–30 second bursts, stirring between each, until smooth.
- Pour the melted chocolate over the peanut butter layer and spread into an even layer.
- Refrigerate for at least 1 hour, or until the chocolate is fully set.
- Lift the bars out using the parchment, let sit at room temperature for 5–10 minutes, then slice into squares.
Notes
For the smoothest chocolate topping, melt slowly and stir often.
If the peanut butter base feels too dry, add 1–2 tablespoons peanut butter and mix again.
For clean slices, use a sharp knife and wipe between cuts. A warm knife helps prevent chocolate cracking.
Store bars chilled for the best texture.
