Preheat oven to 375°F. Lightly coat a 3-quart casserole dish or 9x13 pan with butter or spray with cooking spray.
Cook macaroni according to package directions, adding 2 minutes to the maximum time listed on the package. Drain; stir butter into macaroni until butter is melted.
8 oz. elbow macaroni, 2 tablespoon salted butter
While macaroni is boiling, shred both cheese blocks using a box grater. Combine shredded cheese until evenly mix, then set aside about half of shredded cheese mixture for later.
8 oz extra-sharp white cheddar cheese, 8 oz mild cheddar cheese
In a large bowl, whisk together mascarpone and evaporated milk until smooth (there may still be some lumps, which are okay).

Mix in the whole milk, followed by the salt, creole seasoning, mustard powder, and nutmeg. Stir in half of the shredded cheese mixture.

Notes
Make-ahead instructions: You can prepare this baked mac and cheese the night before and bake the following day! Just complete all the steps except the last one (baking), and place in the fridge covered with plastic wrap. The next day, bake in preheated oven as normal, although you may need to add 5-10 minutes to the cook time. Freezing: This soul food baked mac and cheese freezes very well! Just cool the mac and cheese completely, cover tightly with plastic wrap and foil, and freeze for up to 2 months. Allow to thaw, still wrapped, in the fridge before baking as usual.Updated time/temp: I make this recipe many times a year, and this year I experimented a bit with the temperature. And I found that baking the mac and cheese at a higher temperature for a shorter amount of time produced an even better texture! So the recipe card has been updated to reflect that change.
