Preheat oven to 350°. Grease an 9-x-13” pan with cooking spray or butter.
Beat the butter and sugars until fluffy. Add eggs and vanilla and beat until combined. In a separate bowl, combine flour, salt, cinnamon and baking powder. Add to wet ingredients and beat until just combined. Transfer batter to pan. Sprinkle top with cinnamon-sugar.
Bake for 25-30 minutes. Let cool completely before slicing into squares.
