School Lunch Peanut Butter Bars Recipe Details:

  • Preparation time: 20 minutes
  • Baking time: 25 minutes
  • Cooling time: 1 hour
  • Servings: 16 bars
  • Equipment: 13x9-inch baking pan, mixing bowls, electric mixer, spatula

These School Lunch Peanut Butter Bars bring together the most beloved flavors of childhood desserts in one satisfying treat. The combination of soft, chewy base and rich chocolate topping creates a nostalgic experience that's impossible to resist.

Ingredients:

For the Peanut Butter Base:

  • 1 cup unsalted butter, softened
  • 1 cup creamy peanut butter
  • 1 cup granulated sugar
  • 1 cup packed light brown sugar
  • 2 large eggs
  • 1 teaspoon vanilla extract
  • 2 cups all-purpose flour
  • 1 teaspoon baking soda
  • ½ teaspoon salt
  • 2 cups quick-cooking oats

For the Chocolate Topping:

  • 1 cup semisweet chocolate chips
  • ½ cup creamy peanut butter

Directions:

  1. Preheat your oven to 350°F. Grease a 13x9-inch baking pan or line it with parchment paper, ensuring some overhang for easy removal.
  2. In a large mixing bowl, cream together the softened butter, 1 cup of peanut butter, granulated sugar, and brown sugar. Beat until light and fluffy, which typically takes about 3 minutes using an electric mixer.
  3. Add eggs one at a time, beating well after each addition. Stir in the vanilla extract until thoroughly combined.
  4. In a separate bowl, whisk together the flour, baking soda, and salt. This helps distribute the leavening agents evenly.
  5. Gradually add the dry ingredients to the peanut butter mixture, mixing on low speed. Be careful not to overmix the batter.
  6. Gently fold in the quick-cooking oats, ensuring they're evenly distributed throughout the dough.
  7. Spread the dough evenly into the prepared baking pan. Use a spatula to create a smooth, level surface.
  8. Bake for 20-25 minutes, or until the edges turn golden brown and a toothpick inserted in the center comes out clean.
  9. While the bars bake, prepare the chocolate topping. Melt the chocolate chips and remaining ½ cup of peanut butter in a microwave-safe bowl, stirring every 30 seconds until smooth.
  10. Once the bars are out of the oven, immediately pour the chocolate-peanut butter mixture over the top. Use a spatula to spread it evenly.
  11. Allow the bars to cool completely in the pan on a wire rack. This helps the chocolate topping set properly.

Ready to Relish!

Serve your School Lunch Peanut Butter Bars at room temperature. For an extra nostalgic touch, pair with a cold glass of milk just like you did during school lunches.

Storage Solutions:

  • Store in an airtight container at room temperature for up to 5 days
  • Can be refrigerated for extended freshness
  • Separate layers with parchment paper to prevent sticking
  • Bring to room temperature before serving for best texture
  • Freeze for up to 3 months in a freezer-safe container

Whether you're recreating a beloved childhood memory or introducing a new generation to a classic treat, these School Lunch Peanut Butter Bars deliver the perfect balance of flavors and nostalgia that will have everyone asking for the recipe.
