Preheat oven to 350 degrees.

Place your oats in a food processor and pulse a few times. You are not looking to grind these fine, just making them a coarse mix.

Add the oats, flour, baking powder and cinnamon into a large mixing bowl.

In another bowl using an electric mixer cream the butter and both sugars until light and fluffy.

Next fold in the wet ingredients into the dry ingredients until combined.

Take 1 1/2 tablespoons of dough and roll it into a ball.

Place the cookie balls on a parchment lined baking sheet and press down lightly.

Bake for 12-15 minutes.

Remove from oven and cool completely on a cooling rack.

For the glaze combine the powdered sugar, milk, and water.

Dip the cookie tops into the glaze and place aside to set.

Let the glaze harden about 10 minutes and serve!
