Preheat your oven to 475°F (245°C). If using a pizza stone, place it in the oven to heat up.
In a large bowl, combine the flour, baking powder, and salt. Mix well.
Add the olive oil and warm water to the flour mixture. Stir until a dough forms. Knead the dough on a floured surface for about 5 minutes until smooth.
Roll out the dough into a 12-inch circle or rectangle, about ¼ inch thick. Transfer to a pizza peel or baking sheet lined with parchment paper.
In a medium bowl, mix the corn, mayonnaise, sour cream, lime juice, chili powder, and garlic powder until well combined.
Spread the corn mixture evenly over the rolled-out dough. Top with shredded mozzarella cheese and crumbled cotija cheese.
If desired, add sliced jalapeños on top for extra heat.
Carefully transfer the pizza to the preheated oven (or onto the pizza stone) and bake for 12-15 minutes, or until the crust is golden and the cheese is bubbly.
Remove from the oven and sprinkle with chopped cilantro. Let cool for a few minutes before slicing. Serve with lime wedges on the side.
