Preheat oven to 350°F (175°C) and line a baking sheet with parchment paper.
Spread sugar cookie dough evenly on the baking sheet, pressing down until about half an inch thick. Bake for 12-15 minutes or until golden brown. Let cool completely.
In a mixing bowl, beat together softened cream cheese, powdered sugar, and vanilla extract until smooth.
Once cooled, spread the cream cheese frosting over the cookie base.
Decorate with sliced strawberries in stripes, blueberries as stars, and banana slices around them.
Slice into wedges and serve immediately.
