Step 2: Mix the Wet Ingredients
In a large mixing bowl:
- Pour in the melted butter.
- Add granulated sugar, brown sugar, and creamy peanut butter.
- Stir until smooth and creamy.
- Add eggs one at a time, mixing well after each addition.
- Finally, stir in vanilla extract for that classic sweet aroma.
Step 3: Combine the Dry Ingredients
In a separate bowl, whisk together:
- Flour
- Baking soda
- Salt
Gradually add the dry ingredients to the wet mixture, stirring until fully combined. The batter will be thick and rich—a perfect base for your peanut butter bars.
Step 4: Bake the Base
Spread the batter evenly into the prepared pan. Bake for 20–25 minutes, or until a toothpick inserted into the center comes out mostly clean (a few crumbs are okay; you don’t want to overbake).
Remove from the oven and let it cool slightly while preparing the topping.
Step 5: Prepare the Chocolate Peanut Butter Topping
In a microwave-safe bowl:
- Combine chocolate chips and 1/2 cup peanut butter.
- Microwave in 30-second intervals, stirring after each, until fully melted and smooth.
Pour this glossy topping over the cooled peanut butter base, spreading evenly with a spatula.
Step 6: Chill and Set
Place the pan in the refrigerator for 1–2 hours. This helps the chocolate topping set and makes cutting the bars easier.
Step 7: Slice and Serve
Once set, lift the bars from the pan using the parchment paper edges. Slice into squares or rectangles, and enjoy a chewy, chocolate-peanut buttery treat that tastes just like the classic school lunch version!
Tips for the Perfect Peanut Butter Lunch Lady Bars
- Chewy vs. Soft: Bake closer to 20 minutes for a softer bar, or 25 minutes for a firmer, chewier texture.
- Crunchy Twist: Add 1/2 cup of chopped peanuts to the batter for extra crunch.
- Storage: Store bars in an airtight container in the fridge for up to 5 days, or freeze for longer.
Final Thoughts
Peanut Butter Lunch Lady Bars are more than just a dessert—they’re a nostalgic trip back to childhood lunches. With their chewy texture, rich peanut butter flavor, and chocolatey topping, these bars are perfect for after-school snacks, parties, or anytime you need a sweet pick-me-up.
Baking these at home is simple, fun, and even more satisfying than the cafeteria version. So grab your ingredients, follow the steps, and enjoy a bite of peanut buttery nostalgia!
If you want, I can also make a super-easy version with no mixer and one bowl that’s just as chewy and tasty—perfect for quick baking.
