Preheat & Prep: Preheat the oven to 350°F (175°C). Line a pizza pan or baking sheet with parchment paper.
Make the Dough: In a bowl, cream together the butter and sugar until light and fluffy. Beat in the egg and vanilla. Gradually add flour, baking powder, and salt, mixing until a soft dough forms.
Shape & Bake: Press the dough into a 12-inch circle, about ¼ inch thick. Bake for 12–15 minutes until edges are lightly golden. Cool completely on a wire rack.
Prepare the Frosting: Beat cream cheese and butter until smooth. Add powdered sugar and vanilla, beating until fluffy.
Frost the Cookie: Spread the frosting evenly over the cooled cookie base.
Add the Fruit: Arrange sliced fruit on top in your favorite pattern—circles, rainbows, or freestyle.
Chill & Serve: Refrigerate for 30 minutes before slicing. Cut into wedges and enjoy!
