Preheat oven to 350°F. Prepare an 8 x 8-inch baking pan by spraying it lightly with non-stick spray, lining it with parchment paper so that the paper slightly overhangs, and spraying lightly again; set aside.
In a large bowl, combine melted butter, egg, ½ cup granulated sugar, brown sugar, and vanilla, and stir or whisk until smooth.
½ cup unsalted butter, melted and cooled slightly, 1 large egg, ½ cup granulated sugar, ⅓ cup packed light brown sugar, 1 teaspoon pure vanilla extract
Add flour, baking powder, cream of tartar, and salt; stir until just combined.
1 cup all-purpose flour, 2 teaspoons baking powder, ½ teaspoon cream of tartar, ¼ teaspoon salt
Scrape batter into prepared pan, smoothing the top; set aside.
In the same bowl, combine ¼ cup sugar and cinnamon. Sprinkle cinnamon sugar evenly over the top of the dough.
¼ cup granulated sugar, 2 teaspoons ground cinnamon
Bake 24 to 25 minutes, or until a toothpick inserted in the center comes out clean, or with a few moist crumbs.
