Turn your oven on at 350°F. Set up baking sheets with non-stick mats or parchment.

In a big mixing bowl, combine the flour, oats, spices (cinnamon and nutmeg), baking powder, baking soda, and salt.

Pour the dry mixture into the butter mixture carefully. Mix together till it's all one doughy batch.
06 -
Scoop 2 tablespoons of dough at a time onto baking sheets, with 3-inch gaps between scoops.
07 -
Bake in your preheated oven for 9-10 minutes, just until the edges have browned lightly. Let them cool on the sheet for a bit before moving them to a wire rack.
08 -
Stir together powdered sugar and the vanilla extract. Add just enough milk to get the glaze thick but still pourable.

Take the cooled cookies and dip the tops into the glaze. Let the extra drip off and place them on a rack to let the glaze set up.
