Preheat your oven to 350°F and line a round pizza pan with parchment paper.
In a large bowl, stir together whole wheat flour, oats, cinnamon, and baking powder.
In a separate bowl, whisk the egg, brown sugar, vanilla, and vegetable oil until smooth.
Add the wet ingredients to the dry mixture and stir until just combined.
Spread the dough onto the prepared pizza pan, shaping it into a circle. If it's smaller than your pan, that's okay—just focus on forming a neat round shape.
Bake for 10 minutes or until the crust turns a golden brown. Let it cool completely.
While the crust cools, make the topping by combining Greek yogurt, cream cheese, and sweetener in a bowl. Stir until smooth and creamy.
Spread the yogurt mixture evenly onto the cooled crust.
Top with your favorite fresh fruits, arranging them in colorful patterns for a stunning presentation.
