- Unsalted Butter – Adds richness and moisture to the bars; substitute with coconut oil for a dairy-free option.
- Creamy Peanut Butter – Offers that essential peanut flavor; feel free to use chunky peanut butter for added texture.
- Granulated Sugar – Sweetens the bars; coconut sugar is a lower-glycemic alternative if desired.
- Light Brown Sugar – Enhances moisture with a hint of caramel flavor; swapping for dark brown sugar will deepen the taste.
- Large Eggs – Provides necessary structure and moisture; try flax eggs for a vegan version.
- Vanilla Extract – Boosts flavor depth; opt for pure vanilla extract for the best results.
For the Dry Mixture

Step‑by‑Step Instructions for School Lunch Peanut Butter Bars
Step 1: Preheat the Oven
Start by preheating your oven to 350°F (175°C). While the oven warms up, prepare a 13×9-inch baking pan by greasing it with cooking spray or lining it with parchment paper. This step will ensure your School Lunch Peanut Butter Bars release easily once baked, making for a smooth cooling process afterward.
Step 2: Cream the Ingredients
In a large mixing bowl, combine softened unsalted butter, 1 cup of creamy peanut butter, granulated sugar, and light brown sugar. Using an electric mixer, beat them together on medium speed for about 3 minutes until the mixture is light and fluffy. This creates a rich base for your bars that’s full of flavor.
Step 3: Incorporate the Eggs and Vanilla
Add the large eggs one at a time, ensuring you beat well after each addition. Once all eggs are incorporated, mix in 1 teaspoon of vanilla extract. This step adds warmth and depth to your School Lunch Peanut Butter Bars, making them irresistibly tasty.
Step 4: Whisk the Dry Ingredients
In a separate bowl, whisk together the all-purpose flour, baking soda, and salt. This helps to evenly distribute the leavening agents and salt throughout the mixture. Gradually add this dry mixture to the wet ingredients while mixing on low speed, ensuring everything is combined without overmixing.
Step 5: Fold in the Oats
Gently fold in 2 cups of quick-cooking oats into the batter until they are evenly mixed. This will introduce a chewy texture to your bars, making each bite satisfying. Take care not to overwork the mixture; you want the oats to be just incorporated for the best result.
Step 6: Spread the Batter
Pour the peanut butter oat mixture into the prepared 13×9-inch baking pan. Using a spatula, spread it evenly and smooth the top to ensure a consistent bake. This is a critical step, as an even layer will help your School Lunch Peanut Butter Bars bake uniformly.
Step 7: Bake the Bars
Place the pan in the preheated oven and bake for 20–25 minutes. The edges should turn golden brown and a toothpick inserted into the center should come out clean. Keep an eye on them during the last few minutes to prevent overbaking, as this can affect the texture.
Step 8: Prepare the Topping
While the bars are baking, melt 1 cup of semisweet chocolate chips with the remaining ½ cup of creamy peanut butter in a microwave-safe bowl. Heat in the microwave in 30-second intervals, stirring in between until smooth and fully combined. This luscious topping will enhance the flavor of your School Lunch Peanut Butter Bars.
Step 9: Spread the Topping
Once the bars are finished and slightly cooled, pour the melted chocolate-peanut butter mixture over the top. Use a spatula to spread it evenly across the bars, ensuring every bite is rich and decadent. This step is what will make your bars truly special, adding that delightful chocolate layer.
Step 10: Cool and Cut
Allow the bars to cool completely on a wire rack. This cooling period is essential for the topping to set firmly. Once they are cool, cut the bars into 16 squares using a sharp knife, wiping the blade between cuts for clean edges. Your School Lunch Peanut Butter Bars are now ready to be enjoyed!
