1. Preheat your oven to 425°F (220°C) to ensure even baking and a golden crust.
2. Prepare baking sheets by lightly greasing or lining them with parchment paper to avoid sticking and simplify cleanup.
3. Arrange Tostitos Scoops tortilla chips cup-side up on the prepared baking sheets to create small vessels for the filling.
4. In a large mixing bowl, combine softened cream cheese, shredded mozzarella cheese, one large egg, drained sweet corn, green chiles, garlic powder, salt, and black pepper. Mix thoroughly until the ingredients are well-blended.
5. Using a tablespoon, scoop the prepared filling into each tortilla chip, ensuring the mixture is slightly packed without overflowing the chip.
6. Sprinkle grated Parmesan cheese over the tops of the filled tortilla chips to add a crisp, cheesy topping.
7. Bake the assembled bites in the preheated oven for 13-15 minutes, or until the tops are golden and the filling is bubbling.
8. Remove from the oven and allow the Iowa Party Bites to cool for a minute or two. This helps the filling set and makes them easier to serve and handle.
9. Serve warm for the best flavor and texture. Consider pairing the Iowa Party Bites with dipping sauces like ranch dressing, salsa, or sour cream for added variety.
10. Arrange the bites on a festive platter for an appealing presentation at parties, game days, or gatherings.
