Mix the softened butter and sugar together in a bowl until creamy and light, then beat in the egg and vanilla extract until well combined.
Gradually add the flour to the wet ingredients, mixing until a soft dough forms. Gather the dough into a ball.
Press the dough evenly into a lined baking sheet using your fingers or the bottom of a glass to create a smooth, flat crust.
Bake the crust at 350°F (175°C) for about 15 minutes, or until golden brown. Let it cool completely on a wire rack.
In a bowl, beat the softened cream cheese with powdered sugar and milk until smooth and creamy, then spread this glaze evenly over the cooled crust.
Arrange the chopped strawberries, sliced kiwis, blueberries, and banana slices on top of the glaze, creating a colorful, decorative pattern.
Optional: Garnish with fresh mint leaves or drizzle with honey for an extra touch of flavor and visual appeal.
Slice the fruit pizza with a sharp knife using a gentle sawing motion, ensuring clean cuts without squishing the fruit.
Serve immediately to enjoy the crisp crust and juicy, colorful toppings.
