  • 1/2 cup butter softened to room temperature
  • 1/2 cup granulated sugar
  • 1/2 cup brown sugar
  • 1 large egg
  • 1/2 teaspoon pure vanilla extract
  • 1 cup all-purpose flour
  • 1/2 teaspoon baking soda
  • 1/2 teaspoon salt
  • 3/4 teaspoon cinnamon
  • 1-1/2 cups oats
  • 1 cup chocolate chips


  • 1. Preheat the oven to 350 degrees. Line two baking trays with parchment or silicone liners and set aside.
  • 2. Combine the butter and two sugars in a mixing bowl. Beat until light and fluffy, roughly 4 minutes. 
  • 3. Stir in the egg and vanilla extract. 
  • 4. In a large measuring cup, whisk together the flour, baking soda, salt, and cinnamon. Mix into the butter mixture. 
  • 5. Fold in the oats and the chocolate chips.
  • 6. Optional, chill the dough at least 1 hour or up to 8. 
  • 7. Scoop the cookie dough into round balls that are 1/4 cup per cookie, and place 3 inches apart on the tray. 
  • 8. Bake 10 minutes, or just until the edges are slightly browned. Cool on the tray.
