Step 1

Cut kernels off corn cobs then add to a large mixing bowl. Add butter then toss to coat. Spread corn in a single layer onto a very large sheet pan (or two 13x9 pans). Move oven rack to highest position then heat broiler on high with oven door ajar. Broil corn under high heat with oven door ajar for about 5 minutes or until a few of the kernels begin to char.

Step 2

Remove corn from oven then add back to the mixing bowl. Add mayo, cheese, lime juice, onions, cilantro, salt, garlic powder and chili powder then mix to combine. Taste for seasoning then add more salt and spices if desired.

Step 3

Spoon mixture into a serving bowl then top with additional queso fresco, cilantro and chili powder. Serve warm.
