Iced Oatmeal Gingerbread Cookies are chewy, festive cookies loaded with warm spices, oats, and sweet molasses, topped with a thick vanilla-spiced icing that hardens beautifully. These cookies combine hearty oatmeal texture with the classic warmth of gingerbread spices, balanced by a creamy glaze lightly dusted with additional spices for garnish.
You’ll love these cookies for their perfect chewy centers and slightly crisp edges, full of holiday spice and molasses flavor, complemented by the sweet vanilla icing with hints of cinnamon and ginger. Pulsing oats for texture variety, chilling dough for manageability, and lightly dipping the cooled cookies in thick icing ensures the best flavor and presentation.

-
Pulse oats for texture variety without pulverizing all oats.
-
Chill dough to ease handling and prevent spreading.
-
Bake until edges are golden, not fully browned for softness.
-
Add spices gradually to icing and taste to balance.
-
Dip or drizzle icing over fully cooled cookies for best results.
