Preheat the oven to 375°F/190°C.
In a mixing bowl, combine the flour, yogurt, olive oil, baking powder, and salt until a soft, slightly sticky dough forms; no kneading required. Let the dough rest for 5 minutes while you prepare toppings and line a baking sheet with parchment.
On a lightly floured surface, roll the dough to your desired thickness and trim to a neat circle with a pizza cutter for a tidy edge. Spread crushed tomatoes evenly, scatter the corn, and sprinkle pizza seasoning.
Bake for 10 minutes, remove, top with mozzarella, and return to the oven for 5 minutes more, or until the cheese is melted and golden.
