Preheat your oven to 350°F (175°C). In a mixing bowl, combine your sugar cookie dough with softened unsalted butter until well blended. Roll the dough into small balls, about one tablespoon each, and place them on a parchment-lined baking sheet, spacing them a couple of inches apart. Bake for 8-10 minutes, or until the edges are lightly golden; then allow them to cool completely.

In a clean mixing bowl, beat together the softened cream cheese, powdered sugar, and vanilla extract until the mixture is smooth and creamy. If the frosting is too thick, add a splash of milk to achieve your desired consistency.

Once your cookies are baked, transfer them to a wire rack to cool completely.

Using a spatula or the back of a spoon, spread a generous layer of cream cheese frosting over each cooled cookie.

Arrange your diced mixed fruits atop each frosted cookie.

Assemble the cookies shortly before serving to ensure freshness.
