This is one I "kind of" got from my aunt. She lived on a farm and had real cream so I had to revise it.
3 c. dry macaroni, cooked and drained
1 stick oleo or butter
8 oz. extra sharp cheddar cheese, grated
(Kraft Cracker Barrel Vermont white cheddar)
1 pt. half & half or 1 large can Carnation milk
3 tsp. salt
Pepper
Mix together in blue enamel roaster pan.
Cover with slices of Velveeta cheese - twice.
Bake for 15 min. until cheese is melted, stir in.
Cover with slices of Velveeta cheese the second time.
Bake for 15 min. and stir in.
Bake covered at 350 for total of one hour.
Add more milk, cream or cheese if needed.
This makes a big batch but when I take it to potlucks or for my family, there isn't much left.
Hope it works for you.
