Peanut Butter Oatmeal Cookies

I love a good chewy cookie. Anything that’s slightly undercooked in the middle is the name of the game. Crispy on the outside, chewy on the inside – it’s my idea of perfection and these Peanut Butter Oatmeal Cookies fit the bill.

  • ½ cup butter at room temperature
  • 1 cup brown sugar
  • 1 large egg
  • 1 ½ teaspoon pure vanilla extract
  • ½ cup smooth peanut butter
  • 1 cup all purpose flour
  • ½ teaspoon baking soda
  • 1 pinch kosher salt
  • 1 cup old fashioned oats
  • melted chocolate optional


  • Preheat the oven to 350 degrees F. Line 2 baking sheets with parchment paper and set aside.
  • In a large stand mixer, cream together the butter and sugar for 2-3 minutes.
  • Add in the egg and vanilla and mix until well combined. Be sure to scrape down the sides of the bowl.
  • Add the peanut butter and mix.
  • Add the flour, baking soda and salt and mix until the flour is just combined.
  • Remove the bowl from the stand mixer and fold in the oats.
  • Using a medium sized cookie scoop, scoop 12 cookies onto each baking sheet. Bake for 12 minutes and then remove from the oven. If you don't want a chewy center, bake the cookies for about 13 - 14 minutes. Once the cookies are removed from the oven, let them sit on the baking sheet for a few more minutes before transferring them to a cooling rack.
  • Repeat the process with any remaining dough and store the cookies in an air tight container.
  • Drizzle with melted chocolate if needed.


Gobble them up and pass them out in one sitting / or pop them in a zip top bag and store them in the freezer for when your sweet tooth strikes. They keep for about 2 months in the freezer, although full transparency… I’ve never had them on hand for more than a week or so.
