Ingredients

1 cup unsalted butter (2 sticks, softened)
1 cup creamy peanut butter
1 cup granulated sugar
1 cup packed light brown sugar
2 large eggs
1 teaspoon pure vanilla extract
2 cups all-purpose flour
1 teaspoon baking soda
1/2 teaspoon salt
2 cups quick oats (Do not substitute with old-fashioned rolled oats for authentic texture)
1/2 cup creamy peanut butter
4 tablespoons unsalted butter (softened)
2 teaspoons vanilla extract
3-4 tablespoons milk (as needed)
2 cups powdered sugar

Step-by-Step Instructions

Preheat your oven to 350°F and prepare a 10×15-inch jelly roll pan by lining it with parchment paper or greasing it well.
Cream together 1 cup unsalted butter, 1 cup creamy peanut butter, 1 cup granulated sugar, and 1 cup packed light brown sugar in a large mixing bowl until the mixture is light, fluffy, and smooth.
Add in 2 large eggs one at a time, beating well after each addition, then stir in 1 teaspoon vanilla extract.
Whisk together 2 cups all-purpose flour, 1 teaspoon baking soda, and ½ teaspoon salt in a separate bowl.
Gradually mix the dry ingredients into the wet mixture just until combined.
Gently fold in 2 cups quick oats, ensuring even distribution without overmixing.
Spread the batter evenly into the prepared pan and bake for 30 minutes, or until lightly golden around the edges.
While the bars are baking, prepare the frosting by mixing together ½ cup creamy peanut butter, 4 tablespoons softened unsalted butter, and 2 teaspoons vanilla extract.
Gradually add 2 cups powdered sugar, alternating with 3–4 tablespoons of milk as needed, until smooth and spreadable.
Once the bars are baked and slightly cooled, spread the frosting liberally over the top. Enjoy the nostalgic flavors reminiscent of cafeteria treats!
