Description

These classic iced oatmeal cookies feature soft centers with crisp, chewy edges and a cozy spice blend. The oats are pulsed to create a uniform texture, and the cookies are topped with a thick vanilla icing that sets beautifully after a few hours, making them perfect for gifting or sharing.


Ingredients

Dry Ingredients

  • 2 cups (170g) old-fashioned whole rolled oats
  • 2 cups (250g) all-purpose flour (spooned & leveled)
  • 1 teaspoon baking soda
  • 1 teaspoon salt
  • 1 1/2 teaspoons ground cinnamon
  • 1/2 teaspoon ground nutmeg

Wet Ingredients

  • 1 cup (16 Tbsp; 226g) unsalted butter, softened to room temperature
  • 1 cup (200g) packed light or dark brown sugar
  • 1/2 cup (100g) granulated sugar
  • 2 large eggs, at room temperature
  • 1 Tablespoon (15ml) unsulphured or dark molasses (do not use blackstrap; Grandma’s brand recommended)
  • 2 teaspoons pure vanilla extract

Icing

  • 1 1/2 cups (180g) sifted confectioners’ sugar
  • 1/4 teaspoon pure vanilla extract
  • 1.52 Tablespoons milk


Instructions

  1. Pulse the oats: Using a food processor, pulse the oats 10-12 times so you get a mix of chopped oats and oat flour, creating a variety of texture in the final cookie.
  2. Mix dry ingredients: In a medium bowl, whisk together the pulsed oats, flour, baking soda, salt, cinnamon, and nutmeg. Set this bowl aside for later.
  3. Cream butter and sugars: In a large bowl, use a hand or stand mixer with paddle attachment to beat the butter, brown sugar, and granulated sugar on medium-high speed for about 2 minutes until light and creamy.
  4. Add eggs and flavorings: Beat in the eggs, molasses, and vanilla extract on high speed for about 1 minute until fully combined. Scrape down the bowl as needed to ensure even mixing.
  5. Combine wet and dry: Add the dry ingredients to the wet mixture and mix on low speed until just combined; the dough will be thick and sticky.
  6. Chill the dough: Cover and refrigerate the dough for at least 45 minutes, up to 4 days. If chilling longer than a few hours, let the dough sit at room temperature for 30 minutes before scooping.
  7. Preheat the oven: Set the oven to 350°F (177°C) and line baking sheets with parchment paper or silicone mats.
  8. Scoop and bake: Using about 1.5 tablespoons of dough per cookie, place scoops 3 inches apart on the baking sheets. Bake for 11-12 minutes until the edges are lightly browned and centers still look soft.
  9. Cool the cookies: Let cookies cool on the baking sheet for 5 minutes, then transfer to a wire rack to cool completely before icing.
  10. Prepare the icing: In a medium bowl, whisk sifted confectioners’ sugar, vanilla extract, and 1 tablespoon milk with a fork. Add just enough extra milk to make a very thick icing (about 1 more tablespoon). It should be thick and not runny.
  11. Ice the cookies: Lightly dip the tops of cooled cookies into the icing. Allow the icing to set for a couple hours before stacking or storing.
  12. Store: Keep iced cookies covered at room temperature for up to 3 days or refrigerate up to 10 days.

Notes

  • Pulsing the oats creates a better texture by combining chopped oats and oat flour.
  • Use unsulphured or dark molasses for best flavor; avoid blackstrap molasses as it is too strong.
  • If the dough is too hard after chilling for multiple days, allow it to warm briefly before scooping.
  • The icing is intentionally very thick to set nicely on the cookies without dripping.
  • Cookies are best enjoyed after icing has set for a couple hours.
  • Store cookies covered to maintain freshness and moisture.
