Preheat your oven to 350°F (175°C). This ensures that the cookie base bakes evenly and rises properly.

In a mixing bowl, cream together the softened butter and granulated sugar using an electric mixer on medium speed until light and fluffy, about 2-3 minutes.

Add the egg and vanilla extract to the butter mixture, mixing until fully incorporated.

In a separate bowl, whisk together the sifted flour, baking powder, and salt.

Gradually add the dry ingredients to the wet mixture, mixing on low speed until just combined. Do not overmix to keep the cookie base tender.

Spread the cookie dough evenly onto a greased baking sheet, forming a round pizza shape about ½ inch thick.

Bake in the preheated oven for 12-15 minutes, or until the edges are lightly golden. Allow to cool completely on a wire rack.

In a mixing bowl, beat the softened cream cheese with an electric mixer until smooth and creamy.

Gradually add the powdered sugar and vanilla extract, mixing until well combined.

Fold in the whipped topping gently with a spatula until the mixture is smooth and fluffy.

Once the cookie base has cooled, spread the cream cheese frosting evenly over the top using a spatula.

Arrange the sliced strawberries, kiwi, blueberries, banana, and mandarin oranges artfully over the frosting. Feel free to be creative with your arrangement!

Chill the fruit pizza in the refrigerator for at least 30 minutes before serving to allow the flavors to meld and the frosting to set.

Slice into wedges and serve chilled. Enjoy your colorful and delicious fruit pizza!
