Ingredients
Cookies
- 1 1/4 cups (282 g) unsalted butter
- 2 cups (190 g) old fashioned oats
- 2 cups, plus 4 tablespoons (280 g) all-purpose flour, spooned and leveled
- 2 teaspoons baking soda
- 2 teaspoons ground cinnamon
- 1/2 teaspoon ground nutmeg
- 1 1/2 teaspoons salt
- 1 cup (200 g) light brown sugar, packed
- 1 cup (200 g) granulated sugar
- 2 large eggs, room temperature
- 2 teaspoons vanilla
- 2 tablespoons molasses (not blackstrap)
Icing
- 2 cups powdered sugar, sifted
- 3 tablespoons milk or heavy cream
- 1/4 teaspoon vanilla
Instructions
- Prepare the Baking Sheet: Line a large cookie sheet with parchment paper and set aside for the baking process.
- Brown the Butter: Place the butter in a medium saucepan over medium heat. Stir occasionally until melted. Continue stirring as the butter foams and crackles; after about 4-5 minutes, golden brown bits will form, and the butter will be aromatic and amber colored. Avoid over-browning. Pour the browned butter into a large bowl, scraping all the brown bits from the pan, and set aside to cool for 20 minutes.
- Pulse the Oats: While the butter cools, pulse the oats in a food processor until they form a mix of fine crumbs and larger bits. Set aside.
- Mix Dry Ingredients: In a medium bowl, whisk together the all-purpose flour, baking soda, cinnamon, nutmeg, and salt. Set aside.
- Combine Sugars and Butter: Once the browned butter is cool to the touch, add the light brown sugar and granulated sugar. Whisk for about 1 minute until well combined.
- Add Eggs and Flavors: Whisk in the eggs and vanilla extract until fully incorporated. Stir in the molasses until evenly distributed.
- Incorporate Dry Ingredients and Oats: Add the dry flour mixture and pulsed oats to the wet ingredients. Use a large spatula or wooden spoon to gently fold the mixture together, being careful not to overmix.
- Scoop and Chill Dough: Using a medium cookie scoop, portion uniform scoops of dough onto the prepared cookie sheet. Cover and chill the dough overnight or for at least 3 hours to allow the flavors to meld and the dough to firm up.
- Preheat Oven and Prepare Baking Sheets: When ready to bake, preheat oven to 350°F (175°C). Line two large baking sheets with parchment paper.
- Bake Cookies: Remove dough from refrigerator and transfer dough balls onto prepared baking sheets, spacing them 2 to 3 inches apart. Bake one sheet at a time in the center of the oven for 8 to 10 minutes, until edges are set and lightly golden. Avoid overbaking to keep the cookies chewy.
- Cool Cookies: Remove from oven and let cookies cool on the baking sheet for 5 to 10 minutes. Carefully transfer to a wire rack and cool completely before adding icing.
- Prepare Icing: In a bowl, whisk together the sifted powdered sugar, milk or heavy cream, and vanilla extract until smooth and pourable.
- Ice the Cookies: Once cookies are completely cool, drizzle or spread the vanilla icing over the tops. Allow icing to set before serving or storing.
Notes
- Do not brown the butter too dark; it should be golden and aromatic for best flavor.
- Chilling the dough enhances flavor and texture, making the cookies chewier and better shaped.
- Use parchment paper on baking sheets to prevent sticking and ensure even baking.
- Be careful not to overbake; cookies should be soft and chewy rather than crisp.
- For a dairy-free version, substitute butter with vegan butter and use plant-based milk for icing.
- Molasses provides depth of flavor but avoid blackstrap molasses as it can be bitter.
