Patriotic Fruit Pizza

Preheat oven to 350 degrees F (175 degrees C). Whisk the flour cream of tartar baking soda and salt in a bowl.

In a large mixing bowl mash the vegetable shortening and margarine together until thoroughly combined and beat in 1 1/2 cup of sugar eggs and 1 teaspoon of vanilla extract. Mix in the flour mixture to make a workable dough and spread the dough out in a rectangle shape onto an ungreased 12x17 inch baking sheet.

Bake in the preheated oven until very lightly browned 8 to 10 minutes. Allow to cool completely.

While the cookie base is cooling mash the cream cheese with 1 cup of sugar and 2 teaspoons of vanilla extract in a bowl until smooth. Place sliced bananas in a bowl and gently toss with lemon juice to prevent browning.

To decorate the pizza spread the cream cheese filling all over the cookie base in an even smooth layer. Place the blueberries in a square in neat closely-spaced rows in the left upper corner for blue stars. Arrange alternating stripes of white bananas and red strawberry slices across the pizza. Refrigerate leftovers.
