• 2 2⁄3 cups (342 g) flour
• 2 teaspoons baking powder
• 1  teaspoon salt
• 2  cups packed brown sugar
• 1  cup butter, at room temperature
• 2  eggs, at room temperature
• 1  tablespoon vanilla
• 2  tablespoons white sugar
• 2 teaspoons cinnamon

Preheat oven to 350°. Grease bottom and sides of 9×13 pan; set aside. In a medium bowl, whisk together the flour, baking powder and salt. Set aside. In a large mixing bowl, beat together the butter, brown sugar, eggs and vanilla until smooth. Add the flour mixture to the egg mixture and beat well until blended. Batter will be thick. Spread evenly into the prepared pan. In a small bowl, combine the white sugar and cinnamon. Sprinkle the mixture evenly over the batter in the baking pan. Bake for 25-30 minutes, or until the surface springs back when gently pressed. Remove from the oven and let cool slightly on a wire rack. Cut while warm if desired.
