Lunch Lady Peanut Butter Bars
These Lunch Lady Peanut Butter Bars bring back the classic flavor of old-fashioned school cafeteria desserts. Made with a thick, sweet peanut butter and graham cracker base and topped with a smooth layer of semi-sweet chocolate, they're rich, creamy, and packed with that irresistible chocolate-peanut butter combination.
Equipment
- 9 × 9-inch baking dish
- Parchment paper
- Large mixing bowl
- Stand mixer or handheld mixer
- Microwave-safe bowl
- Measuring cups and spoons
- Rubber spatula
- Knife
- Refrigerator
Ingredients
Peanut Butter Base
- ¾ cup butter melted
- 2 cups graham cracker crumbs
- 2 cups powdered sugar
- 1¼ cups creamy peanut butter
Chocolate Topping
- 2½ cups semi-sweet chocolate chips
- 3 tablespoons creamy peanut butter
Instructions
- Line a 9 × 9-inch baking dish with parchment paper and set aside.
- In a large mixing bowl, combine the melted butter, graham cracker crumbs, and powdered sugar using a stand mixer or handheld mixer until well blended.
- Add 1¼ cups creamy peanut butter and continue mixing just until all ingredients are fully incorporated.
- Transfer the peanut butter mixture into the prepared baking dish. Press and spread evenly across the bottom to create a smooth, compact layer.
- In a microwave-safe bowl, combine the semi-sweet chocolate chips and the remaining 3 tablespoons creamy peanut butter.
- Microwave in 30-second intervals, stirring thoroughly after each interval, until the chocolate is completely melted and the mixture is smooth and creamy.
- Pour the melted chocolate mixture over the peanut butter base, spreading it evenly to cover the entire surface.
- While the chocolate topping is still soft, cut the mixture into 16 squares directly in the pan.
- Refrigerate for 1 hour, or until the bars are completely firm.
- Remove the bars from the refrigerator and let them sit at room temperature for 10–15 minutes before serving.
Notes
Graham cracker crumbs: Use finely crushed crumbs for a smoother, more uniform peanut butter base.
Mixing: Mix the peanut butter layer just until fully combined.
Chocolate: Melt in 30-second microwave intervals, stirring well after each interval to prevent overheating.
Cutting: Cut the bars before chilling to make portioning easier and reduce cracking in the chocolate topping.
Serving: Allow the refrigerated bars to rest at room temperature for 10–15 minutes before enjoying.
Storage: Keep in an airtight container in the refrigerator.
