Preheat the oven to 350 F and line a baking sheet with parchment paper. Very lightly grease with coconut oil or other. Set aside.
Using a large mixing bowl, combine the dry ingredients.
In a separate bowl, cream together the palm shortening and maple syrup. Add the mixture into the flour mixture and stir in the vanilla extract until the ingredients are combined and a dough is formed.
Add the dough to the baking sheet and form it into an 8" round crust that's about 1/4" thick.
Bake in the preheated oven for 12-13 minutes or until the edges are lightly golden brown.
Remove from the oven and allow to cool completely. Don't touch it before it cools or it may break!
For the toppings
Combine the ingredients of the frosting in a bowl and mix well.
Use a spoon or rubber spatula to carefully frost the cookie.
Arrange the fruit in a circular pattern starting with a strawberry outer ring, then kiwi, then grapes, and finally blueberries in the center. Top with lemon zest.
To serve
Use a pizza roller to very carefully slice the cookie. Go slowly to avoid breaking, but if any breaking happens, it's still delicious! :)
Slice it very carefully! This isn't like a typical cookie pizza that you'd buy from the store that's super soft. It's got a bit of a crisp to it, so it can more easily break. Slice it very carefully with a pizza roller.
