Snickerdoodle Blondies

Directions

1. 1
   Preheat oven to 350°F.
2. 2
   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.
3. 3
   In a medium bowl, sift together the flour, baking powder, baking soda, salt, nutmeg, and cream of tarter.
4. 4
   Using an stand mixer, cream together the butter and sugars. Beat for three minutes. Scrape down the bowl.
5. 5
   Add the Mascarpone cheese and beat until fully incorporated.
6. 6
   Add eggs, one at a time, scraping down the bowl after each addition.
7. 7
   Add the vanilla and beat for another 30 seconds.
8. 8
   On low speed add the sifted flour mixture. Mix until fully incorporated.
9. 9
   Spread mixture evenly into prepared pan. This will be hard as it is a thick batter. (I found it easiest to just wet my hands a little and press the batter into the pan.)
10. 10
    Sprinkle more cinnamon sugar on top of the batter.
11. 11
    Bake for 20-25 minutes.
