Ingredients

Scale

Wet Ingredients

  • 1/2 cup (113g) unsalted butter, softened
  • 3/4 cup (150g) packed brown sugar
  • 1/4 cup (50g) granulated sugar
  • 1 large egg
  • 1 teaspoon pure vanilla extract

Dry Ingredients

  • 1 cup (125g) all-purpose flour
  • 1/2 teaspoon baking soda
  • 1/2 teaspoon ground cinnamon
  • 1/4 teaspoon salt

Other

  • 1 1/2 cups (150g) rolled oats
  • Optional mix-ins: raisins, chocolate chips, or chopped nuts

Instructions

  1. Preheat Oven: Preheat the oven to 350°F (175°C) and line two baking sheets with parchment paper to ensure even baking and easy cleanup.
  2. Cream Butter and Sugars: In a large bowl, beat the softened unsalted butter, packed brown sugar, and granulated sugar together until the mixture becomes light and fluffy, which should take about 2-3 minutes. This step incorporates air for tender cookies.
  3. Add Egg and Vanilla: Mix in the egg and vanilla extract thoroughly until fully combined to create a smooth, cohesive base.
  4. Combine Dry Ingredients: In a separate bowl, whisk the all-purpose flour, baking soda, ground cinnamon, and salt to evenly distribute the leavening agent and spices.
  5. Mix Wet and Dry Ingredients: Gradually add the dry ingredients into the wet mixture, stirring gently until just combined to avoid overmixing. Then fold in the rolled oats and any optional mix-ins like raisins, chocolate chips, or chopped nuts, distributing them evenly.
  6. Portion Dough: Using a tablespoon or cookie scoop, drop 1 1/2 tablespoon-sized portions of dough onto the prepared baking sheets, spacing them about 2 inches apart to allow for spreading.
  7. Bake Cookies: Bake the cookies for 10-12 minutes or until the edges turn golden brown while the centers remain slightly underbaked to retain softness.
  8. Cool Cookies: Let the cookies cool on the baking sheet for 5 minutes to firm up before transferring them to a wire rack to cool completely, ensuring perfect texture.

Notes

  • Optional mix-ins such as raisins, chocolate chips, or nuts can be added to customize your cookies.
  • For chewier cookies, bake for the shorter amount of time; for crisper cookies, bake slightly longer.
  • Make sure the butter is softened to room temperature for easy creaming.
  • Store cookies in an airtight container at room temperature for up to one week.
  • You can freeze the cookie dough balls for up to 3 months; bake directly from frozen, adding a couple of extra minutes to the baking time.
