Place corn kernels in a saucepan and cover with salted water; bring to a boil. Reduce heat to medium-low and simmer until tender, 2 to 3 minutes. Drain and return corn to the saucepan to dry.
Spoon 3/4 cup corn into each of 10 serving bowls. Stir 2 tablespoons butter into each bowl until melted. Mix 1/4 cup lime juice and 1/4 cup crema Mexicana into each bowl. Sprinkle 1/8 teaspoon chili powder on top and season with salt.
Top each serving with 2 tablespoons cotija cheese, a dash of hot sauce, and a lime wedge.
