Preheat the oven to 350°F (175°C).
In a medium mixing bowl, whisk together the flour, cocoa powder, baking soda, and salt.
In a separate large mixing bowl, cream together the butter, granulated sugar, and brown sugar until light and fluffy.
Beat in the egg and vanilla extract until well combined.
Gradually add the dry ingredients to the wet ingredients, mixing until just combined.
Stir in the semisweet chocolate chips, white chocolate chips, and dark chocolate chips.
Press the dough into a greased 12-inch pizza pan, forming an even layer.
Bake for 12-15 minutes or until set.
Allow the cookie crust to cool completely.
Once the crust has cooled, arrange the sliced fresh fruit on top of the cookie crust.
Serve and enjoy!
