Preheat oven to 425 degrees. Remove CAULIPOWER Cauliflower Crust from freezer and brush with melted butter.
Combine cinnamon and sugar in a small bowl, stirring until well mixed. Sprinkle mixture across crust. Place CAULIPOWER Cauliflower Crust directly on the middle rack of the oven, and bake for 12-15 minutes, or until the crust is fully cooked and golden brown.
Meanwhile, combine mascarpone, honey, lemon juice and vanilla extract in a medium bowl. Mix until creamy.
Remove pizza from oven and let cool.
Spread mascarpone mixture across crust. Top with fresh mixed berries, and dust with powdered sugar to taste!
