  • 1 cup all-purpose flour
  • ½ tsp baking soda
  • ¼ tsp baking powder
  • ½ tsp sea salt
  • ½ tsp ground cinnamon
  • ½ cup butter softened
  • ½ cup granulated sugar
  • ½ cup brown sugar packed
  • 1 egg
  • 1 tsp pure vanilla extract
  • 1 ½ cup old-fashioned oatmeal
  • 1 cup mix-ins (optional) chocolate chips, raisins, cinnamon chips, etc.


  • Preheat oven to 375 degrees F.
  • Line two large baking sheets with parchment paper. Set aside.
  • In a small bowl, combine the flour, baking soda, baking powder, salt and cinnamon. Set aside.
  • Place softened butter, granulated sugar and brown sugar in the bowl of a standing mixer and beat until combined.
  • Add egg and vanilla and beat on medium speed until the mixture is light (about 30-60 seconds).
  • Add dry ingredient mixture and beat on low speed until just combined.
  • Add oatmeal and beat on low speed until combined.
  • Add mix ins (if desired) and stir until evenly distributed in the dough.
  • Use a 1 ½ to 2 TBS cookie scoop to measure out the dough.
  • Roll the dough into a ball and place on the prepared cookie sheet. Repeat until all the dough is used.
  • Gently and very slightly press down tops of cookies until they are flat.
  • Bake in preheated oven for 8-10 minutes until the top is just set.
  • Let sit on the baking pan for 5 minutes before transferring to a wire rack to cool.


To freeze the oatmeal cookie dough: 

  1. Place oatmeal cookie dough balls on a non-stick cookie sheet and put them in the freezer for 1-2 hours or until firm. 
  2. Transfer to an airtight, freezer-friendly container (I recommend either a glass storage container or a freezer-friendly ziplock bag). 
  3. Freeze for up to 1 month. 
  4. To bake: remove dough from the freezer and let it come to room temperature. Then bake according the the recipe instructions.
