Melt butter in a large skillet over medium high heat. Add corn kernels and jalapeño, and cook, stirring occasionally, until cooked through and slightly charred, about 8-10 minutes.
Stir in mayonnaise, cotija, cilantro, chili powder, garlic and lime juice.
Serve immediately.
Steph S- Suggestion: Add green onion. Can use ricotta cheese. Omit garlic and lime.
