Description

These iced gingerbread oatmeal cookies are chewy, soft, and brimming with gingerbread flavor from molasses, ginger, cinnamon, nutmeg, and cloves. If dipped lightly, the icing will set so you can stack, transport, and/or gift the cookies.


Ingredients

  • 2 cups (170g) old-fashioned whole rolled oats
  • 1 and 2/3 cups (210g) all-purpose flour (spooned & leveled)
  • 1 teaspoon baking soda
  • 1/2 teaspoon salt
  • 2 teaspoons ground ginger
  • 1 and 1/2 teaspoons ground cinnamon
  • 1/2 teaspoon ground nutmeg
  • 1/4 teaspoon ground cloves
  • 3/4 cup (12 Tbsp; 170gunsalted butter, softened to room temperature
  • 1 cup (200g) packed light or dark brown sugar
  • 1/4 cup (50g) granulated sugar
  • 1 large egg, at room temperature
  • 1/4 cup (60ml) unsulphured or dark molasses (do not use blackstrap; I prefer Grandma’s brand)

Icing

  • 1 and 1/2 cups (180g) sifted confectioners’ sugar*
  • 1/4 teaspoon pure vanilla extract
  • 1.52 Tablespoons milk
  • small pinch each: ground cinnamon and ground ginger, plus extra cinnamon for garnish if desired

Instructions

  1. Make the cookies: Pulse the oats in a food processor 10-12 times until you have a variety of texture– chopped oats with some oat flour. See photo above for a visual.
  2. Whisk the pulsed oats, flour, baking soda, salt, ginger, cinnamon, nutmeg, and cloves together in a medium bowl. Set aside.
  3. In a large bowl using a hand mixer or a stand mixer fitted with a paddle attachment, beat the butter, brown sugar, and granulated sugar together on medium-high speed until creamed, about 2 minutes. Add the egg and molasses and beat on high speed until combined, about 1 minute. Scrape down the sides and up the bottom of the bowl and beat again as needed to combine.
  4. Add the dry ingredients to the wet ingredients and mix on low until combined. Dough will be very thick and a little sticky. Cover and chill the dough for 30-45 minutes in the refrigerator (and up to 4 days). If chilling for longer than a few hours, allow to sit at room temperature for at least 30 minutes before scooping and baking because the dough will be quite hard.
  5. Preheat oven to 350°F (177°C). Line large baking sheets with parchment paper or silicone baking mats. Set aside.
  6. Scoop cookie dough, about 1.5 Tablespoons of dough per cookie, and place 3 inches apart on the baking sheets. Bake for 12-13 minutes or until lightly browned on the sides. The centers will look very soft.
  7. Remove from the oven and allow cookies to cool on the baking sheet for 5 minutes before transferring to a wire rack to cool completely before icing.
  8. Make the icing: Combine confectioners’ sugar, vanilla extract, and 1 Tablespoon of milk in a medium bowl. Use a fork to whisk until combined. It will be impossible to fully combine because this isn’t enough liquid. Add only enough extra milk to make a very very thick icing. I only add about 1 more Tablespoon of milk. Whisk in a very small pinch each of ground cinnamon and ginger. (Taste and add more if desired.) Lightly dip the tops of the cookies into the icing or lightly drizzle icing on top. Feel free to dust/sprinkle more ground cinnamon on top of the icing for garnish. Icing will set after a few hours, so you can stack, transport, and/or gift the cookies.
  9. Cookies stay fresh covered at room temperature for 3 days or in the refrigerator for up to 10 days.

Notes

  1. Make Ahead & Freezing Instructions: You can make the cookie dough and chill it in the refrigerator for up to 4 days. Allow to come to room temperature then continue with step 5. Baked cookies with or without icing freeze well for up to 3 months. Unbaked cookie dough balls freeze well for up to 3 months. Bake frozen cookie dough balls for an extra minute, no need to thaw. Read my tips and tricks on how to freeze cookie dough.

  3. Oats: Pulsing the oats in step 1 is the trick to this recipe. If you don’t have a food processor, use a blender. If you don’t have either, give the oats a rough chop on a cutting board. Even if you’re using quick oats, pulsing the oats is necessary—you just won’t have to pulse them as much as whole oats. Do not use oat flour in place of the pulsed oats.
  4. Confectioners’ Sugar: Sift confectioners’ sugar before measuring.
