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 light and fluffy.
- 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.
- 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.
- Mix together ½ cup creamy peanut butter, 4 tablespoons softened unsalted butter, and 2 teaspoons vanilla extract for the frosting.
- Add 2 cups powdered sugar, alternating with 3–4 tablespoons of milk as needed, until smooth.
- Spread the frosting over the baked bars once slightly cooled. Enjoy!
Notes
For a sugar-free version, consider using stevia or monk fruit. Remember not to substitute old-fashioned oats for quick oats as it alters the texture.
