Peanut Butter Oatmeal Cookies

Big, soft, chunky and delicious oatmeal cookies, chock-full of chocolate chips and loaded with peanut butter. Swap the chocolate chips with your favourite chocolate candy bar, such as Toblerone, for a wonderful treat!

You can never have too many cookie recipes. There are so many variations and alternations you can make to a recipe to create new flavours and textures. When you start off with a solid base recipe, it is quite easy to play around with the ingredients and make something different and delicious.

I started off with two of my favourite cookie recipes as my base for these peanut butter oatmeal cookies. These soft baked peanut butter cookies and these oatmeal raisin cookies.

When I think about peanut butter oatmeal cookies, I think big and chunky. The texture should be thick and hearty. I love that you can add lots of different things to this cookie batter and know that the cookies will turn out great.

The rest of the recipe is pretty straight forward. I have made these cookies using different kinds of chocolates and nuts. Each time they turn out delicious so feel free to experiment with the add-ins.

  • 3/4 cup (95 gms) flour

  • 3/4 cup (65gms) whole oats

  • 1/2 teaspoon baking soda

  • 1/2 teaspoon baking powder

  • 1/2 teaspoon salt

  • 1/2 cup (100gms) softened unsalted butter

  • 1/2 cup (100gms) soft light or dark brown sugar

  • 1/4 cup (50gms) white sugar

  • 1/2 cup (120gms) creamy peanut butter*

  • 1 Large egg

  • 1 teaspoon vanilla extract

  • 2 teaspoons unsulphured molasses

  • 1 cup (170gms) semi sweet chocolate chips/chunks


  • In a bowl, whisk together the flour, oats, baking powder, baking soda and salt.
  • In a separate mixing bowl, cream butter, add the white sugar and brown sugar and whisk until paled and fluffy (about 1 minute). Whisk in the peanut butter until smooth and combined. Add in the egg , molasses and vanilla, whisking until combined.
  • Whisk in the flour mix only until just combined, take care not to over mix. Fold in any chocolate chips or nuts if using. Cover dough and chill for minimum 2 hours or overnight if you can.
  • Remove cookie dough from the fridge and allow to sit for about 20 minutes or until the dough has warmed enough for you to scoop balls of dough. Preheat oven to 180C/350F.
  • Roll dough into balls and place onto a baking tray lined with baking paper. Bake until puffy, about 7 minutes. Remove cookie sheet from the oven and bang twice onto a countertop. Return cookies to the oven and continue baking for another 5 minutes until the edges are golden in colour. Make sure not to over bake the cookies. Remove from oven slightly undercooked as they will continue cooking on the cookies sheet once taken out. Leave cookies on hot baking tray until slightly cooled (2 minutes) then place on wire rack to cool for about 5 minutes before placing in an airtight container to cool completely.


  • *For optimal results, I recommend using a commercial peanut butter brand like Skippy of Jif. You can use either crunchy or creamy peanut butter.
