Baked Mac N Cheese

I found this one from RecipeZaar (great resource). Super yum. Josh was in charge of getting the "macaroni noodles" and so we ended up with small shells. But it still tasted good.

1 (12 ounce)bag elbow macaroni
1 pint heavy whipping cream
1 (8 ounce)bag shredded sharp cheddar cheese
1 (8 ounce)bag shredded four cheese blend
2 tablespoons butter or margarine
1 cup chopped onions (walla walla or vidalia if available)
garlic powder
ground black pepper
Directions
Pre-heat oven to 400.
Bring water to boil, then add pasta. Cook uncovered for 8-10 minutes (as directed on package).
While macaroni cooks, chop onions to desired consistency.
Drain pasta and rinse with hot water.
Place pasta back into pot with 2 tbsp butter and stir to cover so pasta does not stick.
Stir in onions and cheese.
Pour in heavy whipping cream and stir until nicely mixed.
Add garlic powder and black pepper to taste.
Scoop mixture into covered casserole dish and bake for 30 minutes, then check for desired bubbliness. ;).
Enjoy!
