Prepare oats by blending in a high speed blender or food processor until coarse crumbs (not powdery though). Set aside.
In a small bowl, whisk together the dry ingredients: prepared oats, flour, salt, baking soda, ginger, cloves, cinnamon, and nutmeg. Set aside.
In the bowl of a stand mixer, cream together softened butter, dark brown sugar, and sugar for about 2 minutes, or until light and fluffy.
Add egg and molasses and beat for a couple of minutes until completely combined.
Add dry ingredients and beat on low speed until just combined. Cover and refrigerate dough for 1 hour.
Just before removing dough from refrigerator, preheat oven to 350* F. Prepare 2 baking sheets by lining with parchment paper or silicone mats.
Scoop cookie dough into mounds, about a tablespoon at a time, onto the prepared cookie sheet, leaving a few inches in between each cookie (they spread!)
Baking for about 14 minutes. Half-way through baking time, take a spatula and lightly flatten the dough mounds. When done allow cookies to cool completely before frosting.
In a small bowl, whisk together glazes ingredients: icing sugar, vanilla, milk, and spices.
Dip each cookie face down in glaze and then turn over to set onto a cooling rack or parchment paper lined plate. Or, you can drizzle the glaze over the cookies if you prefer.
Store in a sealed container in the refrigerator for up to a week or freeze for up to 3 months.
