Place the block of cheese in a 9x13 glass baking dish. Pour the dried elbow pasta around the cheese.
Cover the pasta with the heavy cream and water. Sprinkle the salt, pepper, paprika, onion powder, and garlic powder on top. Mix in. Put 1 tablespoon of butter in each corner of the pan. Do not add the sharp cheddar.
Cover the baking dish with tin foil. Bake for 45-60 minutes (times may vary based on the brand of pasta). If you find that your pasta isn't soft enough after 45 minutes, first check if you need more liquid. You can add ½ or 1 cup of heavy cream or milk and then cover and return it to the oven for 15 minutes.
Remove the baking dish from oven and remove the tin foil. Stir the pasta and add the shredded sharp cheddar cheese 1 cup at a time and stir until it is melted.
