Ingredients Method Notes

Ingredients
  

Ingredients
  • 1 cup creamy peanut butter
  • 1 cup old-fashioned rolled oats
  • 3/4 cup brown sugar
  • 1/2 cup granulated sugar
  • 1/2 cup unsalted butter, softened
  • 1 large egg
  • 1 teaspoon vanilla extract
  • 3/4 cup all-purpose flour
  • 1/2 teaspoon baking soda
  • 1/4 teaspoon salt
  • 1/2 cup chopped peanuts (optional)

Method
 

Instructions
  1. Preheat your oven to 350°F (175°C) and line baking sheets with parchment paper.
  2. In a large mixing bowl, cream together the softened butter, peanut butter, brown sugar, and granulated sugar until light and fluffy (2-3 minutes with an electric mixer).
  3. Beat in the egg and vanilla extract until well combined and smooth.
  4. In a separate bowl, whisk together the flour, baking soda, and salt, then gradually add to the wet ingredients, mixing just until combined.
  5. Stir in the rolled oats and chopped peanuts (if using) until evenly distributed.
  6. Using a cookie scoop or tablespoon, drop rounded balls of dough onto the prepared baking sheets, spacing them about 2 inches apart.
  7. Bake for 10-12 minutes, or until the edges are golden brown and the centers are set.
  8. Let the cookies cool on the baking sheet for 5 minutes before transferring to a wire rack to cool completely.

Notes

Don't overmix when combining wet and dry ingredients. For thicker, chewier cookies, chill the dough for 30 minutes before baking. Use natural creamy peanut butter for best flavor and old-fashioned rolled oats for optimal texture.
