Preheat your oven to 350°F. Arrange the mini phyllo pastry cups on a baking sheet.
In a mixing bowl, combine the corn, red bell pepper, red onion, cilantro, jalapeño, garlic powder, cumin, chili powder, salt, black pepper, and lime juice. Mix well until all ingredients are evenly coated.
Spoon the corn mixture into each mini phyllo cup, filling them generously.
Sprinkle crumbled queso fresco or feta cheese on top of each filled cup.
Bake in the preheated oven for 10-12 minutes, or until the pastry cups are golden and crispy.
Remove from the oven and let cool for a few minutes before serving. Garnish with additional cilantro if desired.
