Ingredients:

  • 1/2 cup (115g) unsalted butter, softened
  • 3/4 cup (190g) creamy peanut butter
  • 1 cup (200g) light brown sugar, packed
  • 1/4 cup (50g) granulated sugar
  • 1 large egg, room temperature
  • 1 tsp vanilla extract
  • 1 1/2 cups (150g) old-fashioned rolled oats
  • 1 1/4 cups (155g) all-purpose flour
  • 1/2 tsp baking soda
  • 1/4 tsp fine sea salt

Instructions:

  1. In a large bowl using an electric hand mixer, cream together the softened unsalted butter, creamy peanut butter, light brown sugar, and granulated sugar for approximately 3 minutes until the mixture is pale and fluffy.
  2. Add the egg and vanilla extract to the creamed mixture and beat until just combined.
  3. In a separate medium bowl, whisk together the all-purpose flour, baking soda, and fine sea salt. Gradually add the dry ingredients to the wet ingredients, mixing on low speed until combined.
  4. Fold in the old-fashioned rolled oats by hand using a spatula until evenly distributed throughout the thick dough.
  5. Using a medium cookie scoop (approx. 1.5 tablespoons), portion the dough onto parchment-lined baking sheets. Bake at 350°F (175°C) for 10 minutes or until the edges are golden brown but the centers still look soft.
