To make these delectable Peanut Butter Lunch Lady Cookie Bars, you’ll need the following ingredients:

  • 1 cup of creamy peanut butter
  • 1/2 cup of unsalted butter, softened
  • 1 cup of granulated sugar
  • 1 cup of packed light brown sugar
  • 2 large eggs
  • 1 teaspoon of vanilla extract
  • 2 cups of all-purpose flour
  • 1 teaspoon of baking powder
  • 1/2 teaspoon of salt
  • 1 1/2 cups of semi-sweet chocolate chips


  1. Preheat your oven to 350°F (175°C) and grease a 9×13-inch baking dish.
  2. In a large mixing bowl, cream together the peanut butter, softened butter, granulated sugar, and brown sugar until smooth and creamy.
  3. Add the eggs, one at a time, beating well after each addition. Stir in the vanilla extract.
  4. In a separate bowl, whisk together the flour, baking powder, and salt. Gradually add the dry ingredients to the wet ingredients, mixing until well combined.
  5. Fold in the semi-sweet chocolate chips until evenly distributed throughout the dough.
  6. Spread the dough evenly into the prepared baking dish, using a spatula to smooth the top.
  7. Bake in the preheated oven for 25-30 minutes, or until the edges are golden brown and a toothpick inserted into the center comes out clean.
  8. Allow the bars to cool completely in the baking dish before cutting into squares and serving.

Serving and Storage Tips:

  1. Serving Suggestions: Peanut Butter Lunch Lady Cookie Bars are best enjoyed fresh out of the oven when they’re still warm and gooey. Serve them as a delicious dessert with a scoop of vanilla ice cream for an extra indulgent treat. You can also cut them into smaller squares and serve them at parties or gatherings as a delightful finger food.
  2. Storage: If you have any leftovers (which is rare because they’re so delicious!), store them in an airtight container at room temperature for up to 3-4 days. Make sure to let them cool completely before storing to prevent them from becoming soggy. If you want to prolong their freshness, you can also store them in the refrigerator for up to a week.
  3. Freezing: These cookie bars freeze exceptionally well, making them perfect for meal prep or for keeping on hand for unexpected cravings. Once cooled, wrap individual bars or the entire batch tightly in plastic wrap and then aluminum foil to prevent freezer burn. They can be frozen for up to 2-3 months. When ready to enjoy, simply thaw them at room temperature or reheat them in the microwave for a few seconds for that freshly baked taste.
  4. Reheating: If you prefer your cookie bars warm and melty, you can easily reheat them in the microwave or oven. For the microwave, place a single serving on a microwave-safe plate and heat on high for 10-15 seconds, or until warm. If using the oven, preheat it to 300°F (150°C), place the bars on a baking sheet, and heat for 5-7 minutes, or until warmed through. Be careful not to overheat them, as they can become dry.

By following these serving and storage tips, you can ensure that your Peanut Butter Lunch Lady Cookie Bars stay fresh, delicious, and ready to enjoy whenever you need a sweet pick-me-up!


  1. Can I use natural peanut butter instead of creamy peanut butter?
    • Yes, you can use natural peanut butter, but keep in mind that it may alter the texture slightly since natural peanut butter tends to be runnier. You may need to adjust the amount of flour in the recipe to compensate for this.
  2. Can I substitute margarine for butter in this recipe?
    • While margarine can be used as a substitute for butter, it may affect the flavor and texture of the cookie bars. Butter adds richness and flavor that margarine may not fully replicate. If you choose to use margarine, make sure it’s in stick form and not spreadable.
  3. Can I use a different type of chocolate chips?
    • Absolutely! Feel free to experiment with different types of chocolate chips, such as milk chocolate, dark chocolate, or even white chocolate. You can also mix and match different types for a unique flavor profile.
  4. Can I make these cookie bars gluten-free?
    • Yes, you can make them gluten-free by using a gluten-free flour blend instead of all-purpose flour. Just make sure the other ingredients, like the chocolate chips, are also gluten-free.
  5. Can I add nuts or other mix-ins to the cookie bars?
    • Of course! Chopped nuts, such as walnuts or pecans, would be a delicious addition to these bars. You can also add other mix-ins like dried fruit, shredded coconut, or even candies for extra flavor and texture.
  6. Do I need to refrigerate the dough before baking?
    • No, you don’t need to refrigerate the dough before baking. However, if you find that the dough is too soft to spread evenly in the baking dish, you can chill it in the refrigerator for about 30 minutes to firm it up slightly.
  7. Can I use a different size baking dish?
    • While a 9×13-inch baking dish is recommended for this recipe, you can use a slightly smaller or larger dish if needed. Just keep in mind that the baking time may vary depending on the size of the dish and the thickness of the dough.
  8. Can I make these cookie bars ahead of time?
    • Yes, you can make the cookie bars ahead of time and store them in an airtight container at room temperature or in the refrigerator until ready to serve. They also freeze well for longer-term storage.
  9. How can I prevent the cookie bars from becoming too dry?
    • To prevent the cookie bars from becoming too dry, be careful not to overbake them. They should be slightly soft in the center when you remove them from the oven. You can also store them in an airtight container to help retain moisture.
  10. Can I halve the recipe to make a smaller batch?
    • Yes, you can halve the recipe if you want to make a smaller batch of cookie bars. Just adjust the ingredient quantities accordingly and use a smaller baking dish. Keep in mind that the baking time may also need to be adjusted.


Once cooled, these Peanut Butter Lunch Lady Cookie Bars are ready to be enjoyed! Serve them as a delightful snack with a glass of cold milk, or pack them in lunchboxes for a special treat.
