As stated in my last recipe, I didn't have the heavy cream. This recipe was used, and definitely works! I took into account the commenter's thoughts on this recipe and added one tablespoon of flour to thicken it.
Total Time: 2 minutes
3/4 cup milk
1/4 cup butter
1 tablespoon flour
Melt the butter. Mix in the milk and flour. Allow to heat and thicken.
