Patriotic Fruit Pizza

1 . Stage

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

2 . Stage

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.

3 . Stage

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

4 . Stage

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.

5 . Stage

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.
