Introduction

Ingredients
- 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)
- 2 cups powdered sugar, sifted
- 3 tablespoons milk or heavy cream
- 1/4 teaspoon vanilla
Instructions
- Step 1: Line a large cookie sheet with parchment paper and set aside.
- Step 2: Place the butter in a medium saucepan over medium heat. Stir occasionally until melted, then continue stirring as it foams and crackles. After about 4-5 minutes, when the butter turns amber and you see golden brown bits forming, remove from heat. Pour the butter into a large bowl, scraping the brown bits from the pan. Let cool for 20 minutes.
- Step 3: While the butter cools, pulse the oats in a food processor until a mix of fine crumbs and larger bits remains. Set aside.
- Step 4: In a medium bowl, whisk together the flour, baking soda, cinnamon, nutmeg, and salt. Set aside.
- Step 5: Once the butter is cool to the touch, whisk in the brown sugar and granulated sugar until combined, about 1 minute.
- Step 6: Add the eggs and vanilla to the butter-sugar mixture, whisking well to combine.
- Step 7: Stir in the molasses until incorporated.
- Step 8: Fold the dry ingredients and pulsed oats into the wet mixture using a large spatula or wooden spoon. Avoid over mixing.
- Step 9: Using a medium cookie scoop, drop uniform scoops of dough onto the prepared cookie sheet. Cover and chill overnight or for at least 3 hours.
- Step 10: Preheat the oven to 350°F (175°C). Line two large baking sheets with parchment paper.
- Step 11: Place chilled dough balls on the baking sheets about 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 golden brown. Avoid over baking.
- Step 12: Let cookies cool on the baking sheet for 5 to 10 minutes before transferring to a wire rack to cool completely.
- Step 13: To make the icing, whisk together powdered sugar, milk or heavy cream, and vanilla until smooth.
- Step 14: Once cookies are cooled, drizzle or spread the icing on top and let it set before serving.
Tips & Variations
- Use parchment paper to ensure cookies don’t stick and bake evenly.
- For a nuttier flavor, add 1/2 cup chopped walnuts or pecans to the dough.
- Substitute molasses with maple syrup for a different but delicious sweetness.
- Chilling the dough overnight intensifies the flavors and improves texture.
Storage
Store these cookies in an airtight container at room temperature for up to 5 days. To extend freshness, refrigerate for up to 1 week. Reheat gently in the microwave for 10-15 seconds to soften before eating. Iced cookies should be kept in a single layer to prevent the icing from smudging.

FAQs
Can I make these cookies gluten-free?
Yes, you can substitute the all-purpose flour with a gluten-free blend suitable for baking. Be sure it contains a binding agent for best results.
What if I don’t have molasses on hand?
You can replace molasses with an equal amount of maple syrup or honey. It will slightly alter the flavor but still add the necessary moisture and sweetness.

Ingredients
For the 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 extract
- 2 tablespoons molasses (not blackstrap)
For the Icing
- 2 cups powdered sugar, sifted
- 3 tablespoons milk or heavy cream
- 1/4 teaspoon vanilla extract
Instructions
- Prepare for Baking: Line a large cookie sheet with parchment paper and set aside to prevent sticking and ensure even baking.
- Brown the Butter: In a medium saucepan over medium heat, melt the butter, stirring occasionally. Watch closely as the butter foams and crackles; after about 4-5 minutes, golden brown bits will form at the bottom and the butter will turn an amber color with a nutty aroma. Remove promptly to prevent burning and pour into a large bowl, scraping the browned bits from the pan. Let cool for 20 minutes.
- Process the Oats: While the butter cools, pulse the old fashioned oats in a food processor until you achieve a mix of fine crumbs and larger bits resembling a coarse oat flour. Set aside.
- Mix Dry Ingredients: In a medium bowl, whisk together the all-purpose flour, baking soda, ground cinnamon, ground nutmeg, and salt. Set aside for later use.
- Combine Sugars and Butter: Once the browned butter has cooled to the touch, whisk in the light brown sugar and granulated sugar until combined and smooth, about 1 minute.
- Add Eggs and Flavorings: Whisk in the eggs and vanilla extract until the mixture is well blended. Then stir in the molasses thoroughly.
- Combine Dry Ingredients and Oats: Gently fold the dry ingredient mixture and pulsed oats into the wet ingredients using a large spatula or wooden spoon. Be careful to fold and not overmix to maintain a tender texture.
- Shape and Chill the Dough: Using a medium cookie scoop, portion uniform balls of dough onto the prepared cookie sheet. Cover them and refrigerate overnight or at least 3 hours to allow the dough to firm up and flavors to meld.
- Preheat Oven and Prepare Baking Sheets: Preheat your oven to 350°F (175°C). Line two large baking sheets with parchment paper for baking.
- Bake the Cookies: Remove the chilled dough balls and place them 2 to 3 inches apart on the lined baking sheets. Bake one sheet at a time in the center of the oven for 8 to 10 minutes, or until edges are set and lightly golden brown. Avoid overbaking for the best soft and chewy texture.
- Cool the Cookies: Allow the cookies to cool on the baking sheet for 5 to 10 minutes. Then carefully transfer them to a wire rack to cool completely before icing.
- Make the Icing: In a bowl, whisk together powdered sugar, milk or heavy cream, and vanilla extract until smooth and creamy enough to drizzle.
- Ice the Cookies: Once the cookies are fully cooled, drizzle or spread the vanilla icing on top. Let the icing set before serving.
Notes
- Be attentive when browning the butter as it can quickly burn once it passes the golden stage.
- Chilling the dough overnight enhances flavor development and helps prevent excessive spreading during baking.
- Molasses adds a subtle depth of flavor and moisture that balances the sweetness.
- For a dairy-free option, substitute butter with a vegan butter and use plant-based milk for the icing.
- Cookies can be stored in an airtight container at room temperature for up to 5 days.
