Chewy, warmly spiced oatmeal gingerbread cookies topped with creamy vanilla glaze. Crisp edges, soft centers, and gingerbread warmth finished with thick icing for a festive treat.


Ingredients

Scale

Cookies
2 cups old-fashioned rolled oats
1⅔ cups all-purpose flour
1 tsp baking soda
½ tsp salt
2 tsp ground ginger
1½ tsp ground cinnamon
½ tsp ground nutmeg
¼ tsp ground cloves
¾ cup unsalted butter, softened
1 cup packed light or dark brown sugar
¼ cup granulated sugar
1 large egg, room temperature
¼ cup unsulphured or dark molasses (not blackstrap)
Icing
1½ cups sifted confectioners’ sugar
¼ tsp pure vanilla extract
2 tbsp milk
Small pinch each of ground cinnamon and ground ginger
Extra cinnamon for garnish (optional)


Instructions

  1. Prep oats: Pulse oats 10–12 times in a food processor until mixed with coarse and fine bits for texture.

  2. Mix dry ingredients: In a bowl, whisk pulsed oats, flour, baking soda, salt, and spices.

  3. Cream butter and sugar: Using a mixer, beat butter, brown sugar, and granulated sugar on medium speed for 3 minutes until light and fluffy. Add egg and molasses; mix until combined.

  4. Combine wet and dry: Gradually add dry ingredients on low speed until just mixed. The dough will be thick and slightly sticky.

  5. Chill: Cover and refrigerate 30–45 minutes (up to 4 days). If longer chilled, let stand 30 minutes before baking.

  6. Bake: Preheat oven to 350°F (175°C). Line baking sheets with parchment. Scoop 1½ tbsp dough per cookie, spacing 3 inches apart. Bake 12–13 minutes until edges are golden.

  7. Cool: Let cookies cool 5 minutes on the pan, then transfer to wire racks to cool completely.

  8. Make icing: Whisk confectioners’ sugar, vanilla, milk, cinnamon, and ginger until smooth and thick. Adjust milk or sugar for desired consistency.

  9. Decorate: Dip tops of cooled cookies in icing or drizzle over. Dust with extra cinnamon if desired. Let icing harden before stacking.

Notes

Pulse oats for texture variety; don’t fully powder.

Chill dough for shape and chewing quality.

Use unsulphured molasses for best flavor.

Cool cookies fully before icing for smooth set.

Allow icing to dry hours before packaging.
