Start by grating the sharp cheddar and mozzarella cheeses and set them aside. Ensure all your ingredients are ready for easy access.

In a large pot, combine the dried macaroni with enough water to cover it by 1-2 cups. Bring to a rapid boil, then reduce heat to medium-low and cook until al dente, about 6-8 minutes.

Lower the heat and pour in the heavy whipping cream. Gradually add the grated cheeses along with salt, pepper, garlic powder, onion powder, paprika, mustard, and sugar. Stir well.

Keep stirring for about 3-5 minutes until smooth. If too thick, add a splash of water or cream.

Taste and adjust seasonings as desired, then serve hot. Enjoy!
