Making Sugar Cookie Flag Fruit Pizza is straightforward if you follow these simple steps:

1. Preheat the Oven: Begin by preheating your oven to 350°F (175°C). Prepare a pizza pan or large baking sheet by greasing it lightly.
2. Cream Butter and Sugar: In a large bowl, cream together the softened butter and granulated sugar until light and fluffy.
3. Add Egg and Vanilla: Beat in the egg and vanilla extract until well combined.
4. Mix Dry Ingredients: In another bowl, whisk together the flour, baking powder, and salt.
5. Combine Mixtures: Gradually add the dry ingredients to the wet mixture, mixing until a soft dough forms.
6. Spread the Dough: Press the dough evenly onto the prepared pizza pan, shaping it into a large circle.
7. Bake the Base: Place the pan in the preheated oven and bake for 15-20 minutes or until the edges are lightly golden.
8. Cool the Cookie Base: Once baked, remove from the oven and let the cookie cool completely on a wire rack.
9. Prepare the Frosting: In a medium bowl, beat the cream cheese until smooth. Gradually add the powdered sugar and vanilla extract, mixing until creamy and well combined.
10. Frost the Cookie: Once the cookie base is completely cool, spread the cream cheese frosting evenly over the top.
11. Arrange the Fruits: Decorate the top of the frosted cookie with the mixed fresh fruits, arranging them to resemble a flag pattern.
12. Chill and Serve: Optionally, refrigerate the fruit pizza for about 30 minutes before slicing. This helps the flavors meld.
