Sugar Cookie Pizza Crust: Using your stand mixer, add butter and sugar. Mix until light and fluffy.
Add eggs, one at a time until fully incorporated. Add vanilla extract and mix well.
In a medium bowl, add flour, baking soda, baking powder and salt. Whisk to combine.
With the mixer on slow, add about half of the flour mixture, until just combined. Then add the milk and remaining flour mixture. Mix until just incorporated. Cover bowl with foil and refrigerate for one hour.
Preheat oven to 350 degrees F.
Roll out the dough on to a lightly floured work surface. Roll the dough until it's about 1/4" thick, then using a circle cookie cutter or a glass cup, cut out to make mini pizzas. You'll have to re-roll out the dough a few times to get all of the pizzas.
Place on a ungreased cookie sheet and bake for 13 minutes. Remove from oven and immediately transfer cookies to a wire rack to cool.
Cream Cheese Sauce: While the cookies are baking or cooling, make the cream cheese frosting.
Add the cream cheese and 1/2 cup powdered sugar to your stand mixer. Mix until combined. Add remaining 1/2 cup powdered sugar and mix until all combined. Ladle sides and bottom of bowl.
With the stand mixer on slow, start adding the heavy cream. Once the cream had been added and mixture is thickening up, increase speed slightly. Add vanilla extract and mix until well combined.
Make Pizzas: Take a cookie and spoon about 1 tablespoon onto the top. Spread the cream cheese out, just like you would a pizza. Then add your fruit toppings any way you'd like.
Eat & Enjoy!
