Preheat oven to 350°. Line a 9x13 inch baking pan with parchment paper. Lightly grease exposed parchment paper and pan. (I use the baking Pam spray)
In a large bowl or mixer, cream together butter and sugars. Mix in eggs and vanilla followed by dry ingredients. Mix until smooth and no streaks or lumps remain. Lightly grease hands (I use the Pam spray again), press mixture into an even layer in prepared baking pan.
Sprinkle with cinnamon and sugar topping, then bake for 25-30 minuets until a tooth pick comes out clean. Let cool, then enjoy!
