Preheat your Blackstone griddle to medium-high heat (about 400°F).
Add the frozen corn directly to the griddle and cook for 6–8 minutes, stirring occasionally, until lightly charred and golden brown.
Transfer the corn to a large mixing bowl. Add the serrano chiles, green onions, mozzarella, pepper jack, pickled jalapeños, cream cheese, queso cotija, Tequila Lime Seasoning, paprika, garlic powder, salt, and black pepper. Mix until well combined.
Preheat your Blackstone Pizza Oven to 650–700°F.
Transfer the mixture to a cast iron skillet or oven-safe baking dish. Sprinkle a little extra mozzarella and pepper jack cheese over the top.
Place the skillet in the pizza oven and cook for 6–8 minutes, rotating halfway through if needed, until the cheese is melted, bubbly, and golden brown on top.
Carefully remove from the oven and garnish with additional queso cotija and fresh cilantro.
Serve immediately with tortilla chips while hot and cheesy.
