Iced Oatmeal Cookie Recipe with Coffee Icing

These thin and chewy oatmeal cookies are frosted with a simple coffee glaze that takes them over the top. They rise in the oven but settle into a flat, golden round with crispy edges and a tender bite. Want them thicker? Just add a tablespoon or two of extra flour to the dough.

Ingredients

Cookie Dough

1 cup (227 g) unsalted butter (softened)
1¾ cup (156 g) granulated sugar
2 (100 g) large eggs
1 ½ tablespoons honey
2 teaspoons vanilla extract
2¼ cup (270 g) all-purpose unbleached flour
2 teaspoons cinnamon
1½ teaspoons baking soda
½ teaspoon salt
2 cups quick-cooking oats - (not instant or old-fashioned--important for the right texture-see substitution list)

Glaze

1½ cups (180 g) powdered sugar
1 tablespoon black coffee - (or milk if you prefer)

Instructions

Preheat oven to 350˚F (180˚C).
Whip the butter: Cream 1 cup unsalted butter (softened) until smooth. Add 1¾ cup granulated sugar and beat until light and fluffy.
Add wet ingredients: Beat in 2 large eggs, 1 ½ tablespoons honey, and 2 teaspoons vanilla extract
Mix dry ingredients: In a separate bowl, whisk 2¼ cup all-purpose unbleached flour, 2 teaspoons cinnamon, 1½ teaspoons baking soda, and ½ teaspoon salt.
Combine and stir in oats: Add the dry ingredients to the butter mixture. Stir until mostly combined, then fold in 2 cups quick-cooking oats. The dough will be thick and heavy.
Scoop and bake: Drop by rounded teaspoons (or use a small cookie scoop) onto parchment-lined baking sheets. Leave room to spread. Bake at 350˚F (180˚C) for 11–13 minutes until golden around the edges.
Cool completely: Let cookies sit for a minute or two before transferring to a wire rack to cool completely.
Make the glaze: Combine 1½ cups powdered sugar with 1 tablespoon black coffee (or milk). Stir until smooth and spreadable. Add more liquid, a few drops at a time if needed.
Ice the cookies: Use a spoon or offset spatula to spread glaze on each cookie once cooled. Let dry completely before storing.

Notes

Browned-Butter Glaze is also delicious on these cookies.
Can I freeze these cookies? Yes. Store in an airtight container. Double wrap for best results. Best if eaten within 1-2 months.
Let the icing dry before packing cookies. Use wax paper, parchment, or plastic wrap between the layers.
