01 - Place eggs in a saucepan and cover with cold water. Bring to a boil, then reduce heat, cover, and simmer for 10 minutes. Transfer to an ice bath to cool completely, then peel and halve lengthwise.
02 - Carefully remove the yolks from each egg white half and place them in a mixing bowl. Set the egg white halves aside on a serving platter.
03 - Heat olive oil in a small skillet over high heat. Add corn kernels and sauté until slightly charred, about 3–4 minutes. Remove from heat and let cool.
04 - To the bowl of egg yolks, add mayonnaise, sour cream, lime juice, smoked paprika, chili powder, garlic powder, and salt. Mash and stir until smooth and creamy.
05 - Gently stir the charred corn, crumbled cotija cheese, and chopped cilantro into the yolk mixture until evenly distributed.
06 - Pipe or spoon the filling back into the hollowed egg white halves, dividing it evenly among all 12 halves.
07 - Top each filled egg with additional crumbled cotija cheese, a light dusting of chili powder, and chopped cilantro. Serve with lime wedges on the side if desired.
