8 ounces (two sticks) unsalted butter, at room temperature
1 cup granulated sugar
1 cup loosely packed light brown sugar
3 ounces Mascarpone cheese
2 eggs
1 tsp vanilla extract
½ tsp baking powder
1 tsp baking soda
pinch of salt
¾ tsp cream of tarter
¼ tsp freshly grated nutmeg
2 cups all-purpose flour

Preheat oven to 350F. Butter a 9 by 13-inch pan. Sprinkle cinnamon sugar and move pan around to make sure that the bottom and sides are coated. Set aside. In a medium bowl, sift together the flour, baking powder, baking soda, salt, nutmeg, and cream of tarter.
Using an stand mixer, cream together the butter and sugars. Beat for three minutes. Scrape down the bowl. Add the Mascarpone cheese and beat until fully incorporated.
