1-1/2 teaspoons cornstarch 
3 tablespoons sugar 
3/4 cup chopped fresh strawberries 
3/4 cup chopped fresh or frozen rhubarb 
1 tablespoon water 
FILLING:
1 package (8 ounces) cream cheese, softened 
1/4 cup sugar 
1 large egg, lightly beaten 
CAKE:
2 cups all-purpose flour 
3/4 cup sugar 
1/2 cup cold butter, cubed 
1/2 teaspoon baking powder 
1/2 teaspoon baking soda 
1/4 teaspoon salt 
1 large egg, room temperature, lightly beaten 
3/4 cup fat-free sour cream 
1 teaspoon vanilla extract
1. Preheat oven to 350°. Line bottom of a greased 9-in. springform pan with parchment; grease parchment. In a small saucepan, mix cornstarch and sugar; stir in strawberries, rhubarb and water. Bring to a boil. Reduce heat; simmer, uncovered, until thickened, 6 to 8 minutes, stirring occasionally. For filling, in a small bowl, beat cream cheese and sugar until smooth. Beat in egg. 
2. In a large bowl, combine flour and sugar; cut in butter until crumbly. Reserve 3/4 cup for topping. Stir baking powder, baking soda and salt into remaining flour mixture. In a small bowl, whisk egg, sour cream and vanilla until blended; gently stir into flour mixture (do not overmix). 
3. Spread batter onto bottom and 1/2 in. up sides of prepared pan. Spread filling over crust, leaving a 1/2-in. border around edge of pan. Spoon strawberry mixture over top; sprinkle with reserved crumb mixture. 
4. Bake until edges are golden brown, 50 to 60 minutes. Cool on a wire rack 20 minutes. Loosen sides from pan with a knife. Cool completely. Remove rim from pan. Refrigerate leftovers.
