Before You Begin:
Prepare your cookware as needed. Cooking times and results may vary depending on your equipment and ingredients.
Preheat the oven to 350°F (177°C) and lightly grease a pizza pan.
Whisk together flour, cornstarch, baking powder, and salt.
Beat butter and sugar until creamy. Add egg and vanilla and mix until combined.
Add dry ingredients and mix until a soft dough forms. Chill for 20 minutes.
Press dough into a 9–10 inch circle on the prepared pan.
Bake for 17–19 minutes, until edges are lightly golden. Cool completely.
Beat cream cheese, butter, powdered sugar, and vanilla until smooth.
Spread frosting evenly over the cooled crust.
Arrange fruit on top. Slice and serve.
