  • 1 1/2 cups all purpose flour
  • 1 tsp baking soda
  • 1/2 tsp salt
  • 1 cup unsalted butter (softened butter)
  • 1 cup creamy peanut butter
  • 1 1/4 cups light brown sugar (packed)
  • 3/4 cup granulated sugar
  • 2 large eggs
  • 2 tsp vanilla extract
  • 1 3/4 cups old fashioned oats
  • 2 cups peanut butter chips (optional)


  • Add the flour, baking soda, and salt to a medium bowl, and stir them together.
  • Add the butter and peanut butter to a large bowl (a stand mixer works best or use a hand mixer) and cream them together until they are totally smooth.
  • Add in the sugars, and mix them into the butters for about 2 minutes, until light and fluffy.
  • Add in the eggs, one at a time, until just mixed. Then stir in the vanilla extract.
  • Add in the flour mixture, and stir them to combine, scraping the bottom and sides of the bowl as needed.
  • Add in the oats and peanut butter chips and fold them into the dough until combined.
  • Cover the bowl with plastic wrap and place it in the fridge for 30 minutes to chill.
  • Preheat the oven to 350 degrees Fahrenheit. Line a cookie sheet or two with parchment paper, or a silicone liner.
  • Scoop 2 TBS of dough and roll it into a ball. Place the ball onto the prepared baking sheet, about 3 inches apart.
  • Bake the cookies for 9 to 12 minutes, or until the edges are golden brown and the tops look just set.
  • Remove the pan from the oven and let the cookies cool on the tray for 10 minutes. Then transfer them to a cooling rack to cool completely.
