Rinse and drain the berries you’ll use to decorate your fruit pizza well ahead of time. After rinsing, lay the berries out on a kitchen towel to allow all the water to drain.
Next, make the cookie pizza crust. Follow the directions on your boxed cookie mix to make the dough. Lay a piece of parchment paper over a large round pizza stone or pan, and spread the cookie dough batter evenly over the parchment covered pizza stone. Don't be afraid to use your hands to get it just right. The parchment paper will keep the dough from sticking to the stone or pan, and will also allow you to move the fruit pizza easily when you’re ready to serve it. Allow for just a bit of extra room around the edges as the cookie will expand as it bakes. Bake the cookie dough for around 17-20 minutes (this will depend on your boxed mix and your oven...I baked mine for 18 minutes), watching carefully so as not to over bake the cookie. Remove it from the oven when the edges are just turning light brown. Be sure to allow the cookie dough crust to cool completely.
In a medium bowl, mix the softened cream cheese, the thawed whipped topping and the zest of half a lemon. Mix well by hand.
After the cookie dough crust has cooled completely, spread the topping mixture evenly over the top using a flat spatula. Leave a bit of room around the edges for the pizza “crust”.
Decorate the frosted cookie with the berries as you’d like. This is a fun job for the kids!
Store fruit cookie pizza in the refrigerator until ready to serve. Slice as you would a pizza and store any leftovers in the refrigerator to be eaten within a day or two.
