Preheat the oven to 400 degrees.
Whisk the eggs in a large bowl.
Gradually pour in the melted butter, little by little. Add in the sugar and cornstarch and mix well to combine.
Add in drained corn and cream style corn. Mix well and pour the corn mixture into a buttered 9" x 13" prepared baking dish.
Bake the corn casserole for 1 hour or until the top is golden brown and bubbling around the edges.
Allow the casserole to cool slightly, about 5-10 minutes. Top with the cilantro, lime wedges, jalapeno slices, chili powder, sour cream and cotija cheese. Serve immediately.
