In a medium bowl, cream together sugar, butter and egg with a hand mixer.
In another bowl, mix flour, cream of tartar, baking soda and salt.
Add dry ingredients to creamed mixture and mix until well combined.
Dip hands in flour and spread dough onto a lightly greased pizza pan until it is approximately ¼ inch thick. Leave 1–2 inches around the edges of the pan for dough to expand.
Bake for 10 minutes, then let cool.
While crust cools, make the frosting. In a medium bowl, cream together cream cheese, sugar and pineapple juice with the hand mixer. Spread over cooled cookie crust.
Right before serving, add desired fruit in the pattern you prefer. Tip: Dip bananas in pineapple juice to keep them from getting dark fast.
Keep refrigerated for up to 3 hours until ready to serve.

Notes
Make Ahead: You can prepare most of the ingredients a day beforehand, but do not assemble the pizza until 2–3 hours before serving. Cook, cool and cover the crust and store at room temperature for up to 24 hours. Store frosting in an airtight container in the refrigerator for up to 24 hours. Do not cut up fruits until ready to assemble pizza.Pressed for Time? If you do not have time to make a homemade crust, you can easily grab a package of sugar cookie dough from the market. Press the dough into the pan and bake at 375 degrees F for about 13 minutes.
