Step 1

Boil the macaroni noodles according to package directions, MINUS one minute (they'll cook a bit more in the oven). Drain and set aside. Preheat the oven to 350F. Grate the cheddar cheese and monterey jack cheese.

Step 2

In a large sauce pan on medium heat, melt the butter. Whisk in the flour and let it cook for another minute and it will form a paste. Slowly pour in the milk and cream, about a quarter of it at a time. Make sure you whisk well each time and let it thicken. Add the chipotle sauce, garlic powder, and salt.

Step 3

Once the mixture has thickened and comes to a gentle boil, turn off the heat. Add the cheeses, and let the remaining heat in the sauce melt the cheese while you gently stir (this stops it from getting stringy). Taste test the sauce at this point and add more chipotle sauce if you want it spicier. When the cheese is melted and the sauce looks creamy and smooth, add the cooked noodles and mix.

Step 4

Grease an 8x8 baking dish with butter, and pour the macaroni in. Melt another tablespoon of butter in the microwave, then mix it with the Cornflakes. Sprinkle this mixture over the mac and cheese, then pop the dish in the oven. Bake at 350F for 20-30 minutes on the middle rack, or until the cheese is bubbly around the edges.
