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 and 1/2 teaspoons ground cinnamon
- 1/2 teaspoon ground nutmeg
Wet and Other 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; preferred Grandma’s brand)
- 2 teaspoons pure vanilla extract
Icing
- 1 and 1/2 cups (180g) sifted confectioners’ sugar
- 1/4 teaspoon pure vanilla extract
- 1.5 – 2 Tablespoons milk
- Pulse the oats: Pulse the rolled oats in a food processor 10-12 times until you achieve a mix of chopped oats and fine oat flour for varied texture in your cookies.
- Mix dry ingredients: In a medium bowl, whisk together the pulsed oats, all-purpose flour, baking soda, salt, ground cinnamon, and ground nutmeg until evenly combined. Set this mixture aside.
- Cream butter and sugars: Using a hand mixer or stand mixer fitted with the paddle attachment, beat the softened butter, brown sugar, and granulated sugar together on medium-high speed for about 2 minutes until light and creamy.
- Add wet ingredients: To the creamed butter and sugars, add the eggs, molasses, and vanilla extract. Beat on high speed for about 1 minute until fully combined, scraping down the bowl sides and bottom to ensure even mixing.
- Combine wet and dry ingredients: Add the dry ingredient mixture to the wet mixture and mix on low speed until just combined. The dough will be thick and sticky.
- Chill the dough: Cover and refrigerate the dough for at least 45 minutes and up to 4 days. If chilled longer than a few hours, allow the dough to sit at room temperature for at least 30 minutes before scooping, as it will be very hard.
- Preheat and prepare baking sheets: Preheat the oven to 350°F (177°C). Line baking sheets with parchment paper or silicone baking mats.
- Scoop and bake: Using about 1.5 tablespoons of dough per cookie, scoop and place the cookies 3 inches apart on the prepared baking sheets. Bake for 11-12 minutes until the edges are lightly browned and the centers appear soft.
- Cool the cookies: Remove cookies from oven and let them cool on the baking sheet for 5 minutes before transferring to a wire rack to cool completely.
- Make the icing: In a medium bowl, combine sifted confectioners’ sugar, vanilla extract, and 1 tablespoon of milk. Whisk with a fork until mixed, then add a little more milk (up to 1 additional tablespoon) to achieve a very thick icing consistency.
- Ice the cookies: Lightly dip the tops of the cooled cookies into the icing. The icing will set after a few hours, allowing you to stack and gift the cookies without mess.
- Storage: Store iced cookies covered at room temperature for up to 3 days or refrigerate for up to 10 days to keep them fresh.
Notes
- Do not use blackstrap molasses; unsulphured or dark molasses gives the best flavor.
- If chilling dough for longer than a few hours, bring to room temperature before baking for easier scooping.
- The icing should be thick so it sets nicely on the cookies and makes them easy to stack and gift.
- Use parchment paper or silicone mats to prevent cookies from sticking during baking.
- Cookies will look soft in the center when removed from oven but will firm up as they cool.
