Preheat oven to 400 degrees.

Start by mixing the butter and brown sugar in a large bowl.

Add the egg and mix again. Set aside.

In another large bowl, mix together all of the dry ingredients except the cinnamon.

Add half of the dry mixture to the butter and sugar, stir together.

Add half of the milk, mix gently.

Add the last half of the dry mixture, mix, and then dump in the remaining milk.

Splash in the vanilla and cinnamon and mix again!

Drop by rounded teaspoonfuls onto an ungreased cookie sheet and bake for 8 - 12 minutes.

Pull out and cool on the pan for 5 minutes and then sprinkle with powdered sugar.

Enjoy!
