Preheat a 12-cup muffin pan in a 425 degrees F oven for 15 minutes.
Meanwhile, whisk together the eggs, milk and melted butter. Whisk in the flour and 1 teaspoon each salt and pepper; let rest 10 minutes.
Generously brush 8 of the muffin cups with the vegetable oil. Fill the 8 cups with the batter and top with the cheese. Bake 20 minutes, then reduce the oven temperature to 350 degrees F and bake until the tops are browned and puffed, 14 to 18 minutes.
