  • Author: Sandra Flegg
  • Total Time: 23 minutes
  • Yield: 48 cookies


3/4 cup butter, softened at room temperature

1 cup brown sugar

1/2 cup granulated sugar

2 large egg

1 teaspoon vanilla extract

1 and 3/4 cups all purpose flour

1 teaspoon baking powder

1/4 teaspoon baking soda

1/2 teaspoon cinnamon (optional but good)

2 cups rolled oats

3 Tablespoons granulated sugar for rolling the unbaked cookie dough balls


  1. Start by creaming together the butter and both sugars, then add in egg and vanilla and beat until well-combined.

  2. Add in the egg and vanilla and beat until well combined.

  3. In a separate bowl, combine flour, baking powder, baking soda and cinnamon (optional but good). 

  4. Gradually add to the butter mixture, mixing slowly after each addition.

  5. Stir in the rolled oats. I find this step is easier to do by hand with a wooden spoon (or with clean hands). Mix just until combined.

  6. Gather the dough into a ball. 

  7. Roll into 1 and 1/2 inch balls. Dip into granulated sugar, then flatten slightly and place on parchment paper-lined or (silpat sheet) baking sheet. 

    Bake in 375F oven for 8 to 10 minutes until edges are golden. Cookies will still appear soft in the middle. 

  8. Take them out of the oven and let them cool on the baking sheet for one minute, then transfer to a wire cooling rack. ENJOY!


Storage: Store in an airtight container at room temperature for 7 to 10 days. An old trick is to place a piece of white bread in the container with the cookies (not directly on top of cookies) will help them stay moist, soft and fresh.

Freezing: Freeze using a freezer-safe container for 2 to 3 months.

Thaw at room temperature before serving.
