How to Make Lunch Lady Peanut Butter Bars Recipe
Step 1: Prepare Your Baking Dish and Preheat Oven
Start by preheating your oven to 350°F (175°C) to get it ready for baking. Grease a 9×13-inch baking dish or line it with parchment paper. This step ensures your peanut butter bars come out perfectly without sticking and with an even bake.
Step 2: Cream the Butter and Sugars
In a large bowl, cream together the softened unsalted butter, granulated sugar, and packed light brown sugar until the mixture is light and fluffy. This creates an airy texture that will give your bars a soft bite with a hint of chewiness, setting a solid foundation for the rest of the ingredients.
Step 3: Add Eggs, Vanilla, and Peanut Butter
Next, beat in the eggs and 1 teaspoon vanilla extract. Then, mix in 3/4 cup of the creamy peanut butter until everything is smooth and well combined. This peanut butter addition lends incredible flavor and moisture to the batter, making these bars truly irresistible.
Step 4: Combine Dry Ingredients
In a separate bowl, whisk together all-purpose flour, baking soda, salt, and quick oats. This mixture brings structure and the much-loved chewy oat texture to the bars.
Step 5: Mix Dry Ingredients into Wet Batter
Gradually add the dry ingredient mix to your wet peanut butter mixture, stirring gently until fully incorporated. Avoid overmixing here to keep the texture tender and soft.
Step 6: Bake and Add Peanut Butter Layer
Spread the dough evenly into your prepared baking dish and pop it into the oven. Bake for 22 to 25 minutes until the bars turn a beautiful golden brown and are set in the center. While the bars are still warm, gently spread the leftover 1/4 cup of peanut butter over the top to create a luscious thin layer that will melt into the surface as they cool.
Step 7: Make and Spread the Frosting
Whip up the frosting by beating powdered sugar, milk, 1/2 teaspoon vanilla extract, and an optional tablespoon of peanut butter until your frosting is smooth and easily spreadable. Once the bars have completely cooled, spread the frosting evenly over the top. Let it set so it gets beautifully firm, giving you that classic frosted finish.
How to Serve Lunch Lady Peanut Butter Bars Recipe
Garnishes
These bars are fantastic on their own, but if you want to add a little extra sparkle, sprinkle some chopped roasted peanuts or a light dusting of cocoa powder on the frosting. A drizzle of melted chocolate also adds an extra indulgent touch that friends and family will love.
Side Dishes
Lunch Lady Peanut Butter Bars go wonderfully with a cold glass of milk or a hot cup of coffee or tea. They also pair beautifully with fresh fruit like sliced bananas or strawberries, making a perfect balance of sweet and fresh flavors.
Creative Ways to Present
If you’re serving these bars at a party or as a gift, consider cutting them into fun shapes using cookie cutters or layering them between sheets of wax paper in a decorative tin. You can even wrap individual bars in parchment paper tied with twine for an inviting homemade touch.
Make Ahead and Storage
Storing Leftovers
You can store leftover Lunch Lady Peanut Butter Bars in an airtight container at room temperature for up to 4 days. Keeping them sealed helps retain their perfect texture and flavor, making them easy to grab for a quick treat during the week.
Freezing
These bars freeze beautifully. Wrap individual squares tightly in plastic wrap and place them in a freezer-safe bag or container. They can be frozen for up to 3 months. When you’re ready to enjoy, simply thaw at room temperature for a few hours or overnight in the refrigerator.
Reheating
If you prefer your bars a bit warm, gently reheat them in the microwave for 10 to 15 seconds or pop them into a low oven at 300°F for about 5 minutes. Be careful not to overheat and melt the frosting too much—you want that luscious layer to stay intact!
FAQs
Can I use chunky peanut butter instead of creamy?
Absolutely! Using chunky peanut butter will add delightful peanut pieces throughout the bars, giving an extra bit of crunch and texture that many people enjoy.
Are these bars suitable for people with nut allergies?
Since peanut butter is the star ingredient, this recipe is not suitable for anyone with peanut or nut allergies. However, you can experiment with a seed butter alternative like sunflower seed butter if allergies are a concern, though the flavor and texture will vary.
What is the best way to ensure the bars don’t turn out too dry?
Make sure to measure the flour correctly and avoid overbaking. Also, the combination of brown sugar, peanut butter, and frosting helps keep these bars wonderfully moist and tender.
Can I substitute quick oats with old-fashioned oats?
You can, but old-fashioned oats will create a chewier, more rustic texture. If you prefer a softer bite typical of the Lunch Lady Peanut Butter Bars Recipe, stick with quick oats.
Is it okay to skip the frosting?
Yes, skipping the frosting will still yield delicious peanut butter bars with a rich, buttery flavor. The frosting just adds a sweet, creamy finishing touch that many love, but it’s completely optional.
