Cookie Ingredients

  • 1 cup unsalted butter, softened provides rich tenderness
  • 1 cup brown sugar, packed deep, caramel-like sweetness
  • 1/2 cup granulated sugar balances sweetness and texture
  • 2 large eggs, at room temperature bind and add moisture
  • 1 teaspoon vanilla extract brings warmth
  • 1 1/2 cups all-purpose flour structure
  • 1 teaspoon baking soda lifts the cookie
  • 1/2 teaspoon baking powder helps a gentle rise
  • 1/2 teaspoon salt enhances all the flavors
  • 2 teaspoons ground cinnamon cozy, classic spice
  • 3 cups old-fashioned rolled oats the chewy, wholesome heart
  • 1 cup raisins or chocolate chips (optional) add-ins for variation

Icing Ingredients

  • 2 cups powdered sugar
  • 2 tablespoons milk more as needed for consistency
  • 1 teaspoon vanilla extract
  • 1 pinch salt

Instructions
 

Preparation

  • Preheat your oven to 350°F (175°C) and line two baking sheets with parchment paper.
  • In a large bowl, cream together the softened butter, brown sugar, and granulated sugar until light and fluffy, about 2 to 3 minutes.
  • Add the eggs one at a time, beating well after each, then stir in the vanilla.
  • Whisk together the flour, baking soda, baking powder, salt, and cinnamon in a separate bowl.
  • Slowly add the dry ingredients to the wet mixture until just combined.
  • Fold in the oats and your chosen add-ins (raisins or chocolate chips).
  • Drop rounded tablespoons of dough onto the prepared sheets, spacing them about 2 inches apart, and flatten slightly with the back of a spoon.

Baking

  • Bake for 10 to 12 minutes, until the edges are just turning golden but the centers still look slightly soft.
  • Remove and let cool on the sheet for 5 minutes before transferring to a wire rack.

Icing

  • Make the icing by whisking powdered sugar, milk, vanilla, and a pinch of salt until smooth.
  • Add more milk a teaspoon at a time if needed to reach a drizzleable consistency.
  • Once cookies are fully cooled, drizzle or spread the icing over them and let set for about 15 minutes.

Notes

For extra chew, use quick oats instead of rolled oats. Consider adding a teaspoon of orange zest to the icing for a brighter twist. Make gluten-free by using a gluten-free flour blend and certified oats.
