Crunchy Peanut Butter Oatmeal Cookies made from scratch.


  • 115 grams (1/2 cup or 1 stick) unsalted butter, room temperature
  • 135 grams (3/4 cup) brown sugar
  • 50 grams (1/4 cup) caster sugar
  • 1 teaspoon vanilla extract
  • 125 grams (1/2 cup) smooth peanut butter
  • 1 large egg
  • 140 grams (1 cup) plain flour
  • 100 grams (1 cup) rolled oats
  • 1/2 teaspoon baking soda
  • 1 teaspoon cinnamon 
  • 80 grams (1/2 cup) raisins
  • 75 grams (1/2 cup) chocolate chips


  1. Preheat oven to 180 C (350 F) standard / 160 C (320 F) fan-forced. Line two oven trays with baking paper. 
  2. In a large mixing bowl, add butter, sugars, vanilla and peanut butter. Beat with an electric mixture until smooth and creamy. Add egg and beat until smooth. Scrape down the sides.
  3. Add flour, oats, baking soda and cinnamon and beat until cookie dough forms. Add raisins and chocolate chips. 
  4.  The dough will still be a bit sticky but it should be firm enough to roll into balls using your hands. Place the balls (approximately 1.5 tablespoons each) of cookie dough onto prepared trays.
  5. Flatten cookie dough balls slightly using the palm of your hand, as they wont spread out as much as a normal cookie would.
  6. Bake cookies for approximately 15-16 minutes or until golden brown on the edges. The cookies will be VERY soft so leave the cookies to cool completely before serving. 


  1. If you can’t find caster sugar, you can use granulated sugar instead.
  2. I recommend using a processed full fat peanut butter (such as Bega, Jif or Skippy) rather than a natural one – that is what has been used for testing this recipe.
  3. Please note that plain flour is the same as all purpose flour.
