Iced Oatmeal Cookies

Ingredients

  • 2 cups (180g) old fashioned oats
  • 1 3/4 cups (248g) all-purpose flour (scoop and level to measure)
  • 1 tsp baking powder
  • 3/4 tsp baking soda
  • 1/2 tsp salt
  • 1 1/2 tsp ground cinnamon
  • 1/2 tsp ground nutmeg
  • 1 cup (226g) unsalted butter, at room temperature
  • 1 1/4 cups packed (250g) light brown sugar
  • 2 large eggs
  • 2 tsp vanilla extract

Icing

  • 1 1/2 cups (180g) powdered sugar
  • 2 Tbsp milk

Instructions

  • Preheat oven to 350 degrees. Pour oats into a food processor and pulse until partially ground, about thirty 1-second blitzes.
  • In a mixing bowl, whisk together flour, baking powder, baking soda, salt, cinnamon, nutmeg and ground oats, for 30 seconds.
  • In the bowl of an electric stand mixer, fitted with the paddle attachment cream together butter and brown sugar on medium-high speed until pale and fluffy, about 2 to 3 minutes. Scrape down bowl.
  • Add in eggs one at a time, mixing until combined after each addition. Stir in vanilla. Scrape down bowl.
  • Add in dry ingredients and mix just until combined. Fold dough with a spatula to ensure it’s evenly incorporated. Let cookie dough chill 30 to 60 minutes in the fridge.
  • Scoop dough out about 2 Tbsp at a time (using a slightly heaped #40 cookie scoop) and drop onto a silpat or parchment paper lined baking sheet. Bake in preheated oven 11 - 15 minutes. Allow cookies to rest on baking sheet 5 minutes before transferring to a wire rack to cool completely.
  • In a mixing bowl whisk together powdered sugar and milk (if needed thicken with a little more powdered sugar, or thin with a little more milk). Dip just the tops of cooled cookies in icing and allow excess to run off or alternately spread icing over cookies.
  • Return to wire rack and allow icing to set. Store in an airtight container at room temperature.

Notes

  • If you’d like these iced oatmeal cookies to be more soft and chewy, then bake them near the lesser amount of time, and for a crispier cookie bake them for the greater amount of time.
