Heat oven to 350°F. In a large bowl of a food processor fitted with blade attachment combine flour, brown sugar and 2 tsp. cinnamon. Pulse until well combined. Add butter slowly, pulsing between additions, until pea-sized pieces form. Press 1/2 of the mixture in an ungreased 9-inch springform pan; set remaining mixture aside.
Place apples, Stevia In The Raw®, cornstarch and remaining 1 tsp. cinnamon in a large bowl; stir to combine. Place apples in prepared springform pan. Evenly sprinkle the remaining mixture over apples.
Place springform pan on baking sheet with sides. Bake 60 to 70 minutes until top is golden. Remove from oven. Run knife around the edge of pan; let cake cool completely. Remove springform ring just before serving.
