Elote, or Mexican street corn, is a popular Mexican snack made with grilled corn on the cob slathered in a creamy, tangy sauce and topped with cheese, chili powder, and lime.
Preheat a grill or grill pan to medium-high heat. Brush corn with vegetable oil.
Grill corn for 10–12 minutes, turning occasionally, until charred and cooked through.
In a small bowl, mix together mayonnaise and sour cream.
Remove corn from grill and while still hot, spread each ear evenly with the mayo-sour cream mixture.
Sprinkle with cotija cheese, chili powder, and cilantro if using.
Serve immediately with lime wedges on the side for squeezing.
