- Preheat the oven to 350°F. 
- In a medium bowl, cream 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. Dip bananas in pineapple juice to keep them from getting dark fast. 
- Keep refrigerated for up to 3 hours until ready to serve.
