Ingredients

  • 1 cup unsalted butter, softened
  • 1 cup granulated sugar
  • 1 cup packed brown sugar
  • 1 cup creamy peanut butter
  • 2 large eggs
  • 2 teaspoons vanilla extract
  • 2 cups all-purpose flour
  • 1 teaspoon baking soda
  • 1/2 teaspoon salt
  • 2 cups quick oats

Instructions

  • Preheat your oven to 350°F (175°C). Grease a 9×13 inch baking dish and set aside.
  • In a large bowl, cream together the butter, granulated sugar, and brown sugar until light and fluffy.
  • Add the peanut butter, eggs, and vanilla extract, and beat until well combined.
  • In another bowl, whisk together the flour, baking soda, and salt.
  • Gradually add the dry ingredients to the wet ingredients, mixing until just combined.
  • Stir in the quick oats until evenly distributed.
  • Spread the dough evenly into the prepared baking dish.
  • Bake for 20-25 minutes, or until the edges are golden brown and a toothpick inserted into the center comes out clean.
  • Allow the cookie bars to cool completely in the baking dish before cutting into squares.

Notes

  • For extra flavor, mix in chocolate chips, dried fruits, or nuts like chopped peanuts.
  • These bars can be made with crunchy peanut butter for an added texture.
  • To keep them fresh for longer, store them in an airtight container. Refrigerate for up to a week or freeze for up to 3 months.
