Peanut Butter Lunch Lady Cookie Bars

INGREDIENTS

For the cookie bars you will need one cup or two sticks of softened unsalted butter, one cup of creamy peanut butter, one cup of granulated sugar, one cup of packed light brown sugar, two large eggs, and two teaspoons of vanilla extract. For the dry ingredients you will need two cups of all purpose flour, one teaspoon of baking soda, and one half teaspoon of salt.

For the peanut butter frosting you will need one half cup of softened unsalted butter, one half cup of creamy peanut butter, two cups of powdered sugar, one teaspoon of vanilla extract, and three to four tablespoons of milk.

STEP BY STEP INSTRUCTIONS

Step one is to prepare the pan. Preheat your oven to three hundred and fifty degrees Fahrenheit. Lightly grease a ten by fifteen inch jelly roll pan or line it with parchment paper for easy removal.

Step two is to cream the butter and sugars. In a large mixing bowl, beat the softened butter, peanut butter, granulated sugar, and brown sugar together until the mixture is creamy and well combined.

Step three is to add the remaining wet ingredients. Beat in the eggs one at a time, ensuring each is fully incorporated before adding the next. Mix in the vanilla extract.

Step four is to add the dry ingredients. In a separate bowl, whisk together the flour, baking soda, and salt. Gradually stir this dry mixture into the wet peanut butter mixture just until a soft, thick dough forms. Do not overmix.

Step five is to spread the dough. Press and spread the dough evenly into your prepared pan, making sure it reaches all the corners.

Step six is to bake. Bake for eighteen to twenty two minutes, until the edges are lightly golden and the center looks set. Avoid overbaking, as the bars should remain soft and chewy after cooling.

Step seven is to cool. Let the cookie bars cool completely in the pan before applying the frosting.

Step eight is to make the frosting. In a medium bowl, beat the softened butter and peanut butter until smooth. Add the powdered sugar and vanilla, then gradually beat in the milk until the frosting is creamy and easily spreadable.

Step nine is to frost and slice. Spread the peanut butter frosting evenly over the completely cooled bars. Let it set for about ten to fifteen minutes, then cut into twenty four squares or rectangles and serve.

SERVING SUGGESTIONS

These rich and decadent bars are best served at room temperature alongside a tall glass of cold milk or a hot cup of black coffee to balance the sweetness. They make a fantastic addition to a dessert table at a potluck, a treat for a school bake sale, or a comforting afternoon snack paired with a piece of fresh fruit.

YOU MUST KNOW

The secret to the perfect texture is to avoid overbaking the cookie base. They will continue to set as they cool, so taking them out when the center is just set ensures a soft and chewy bite. Additionally, it is crucial to let the bars cool completely before adding the frosting; otherwise, the frosting will melt and slide right off. Using creamy peanut butter rather than crunchy or natural varieties, which can separate, yields the best texture for both the dough and the frosting.

STORAGE TIPS

Store the frosted cookie bars in an airtight container at room temperature for up to four days. Place a piece of parchment paper between the layers if you need to stack them to prevent the frosting from sticking. You can also freeze the unfrosted baked bars for up to three months. Thaw them completely at room temperature before adding the fresh frosting.

ASKED QUESTIONS

Can I use crunchy peanut butter instead of creamy?

You can use crunchy peanut butter in the cookie dough for added texture, but it is highly recommended to use creamy peanut butter for the frosting to ensure a smooth and spreadable finish.

What if my frosting is too thick or too thin?

If the frosting is too thick, add another tablespoon of milk. If it is too thin and runny, gradually beat in a little more powdered sugar until it reaches the desired consistency.

Can I make these in a standard nine by thirteen inch baking dish?

Yes, you can use a nine by thirteen inch pan. The bars will be slightly thicker, and you may need to add a few extra minutes to the baking time. Check for doneness around the twenty two minute mark.
