Preheat your oven to 350 °F. Grease a 10-inch round baking dish and set aside.
In a large bowl, mix the sugar, milk, cream, cornstarch, nutmeg, salt and black pepper until the cornstarch has dissolved completely.
Add in the eggs and mix completely.
Stir in the butter, then add in the two different types of corn, mixing everything together thoroughly.
Spoon into the prepared pan.
Bake in the preheated oven for 30-40 minutes, or until the casserole has set. A knife inserted should come out clean, but the casserole is still jiggly!
Notes
Add in some red pepper flakes for heat, or a pinch of cayenne
Lessen the sugar if you like a more savory casserole
