Slow Cooker Mac & Cheese

I found this recipe from Six Sisters' stuff!  It is so creamy!! 

Ingredients:

2 cups uncooked elbow macaroni
4 Tbsp butter
2 1/2 cups grated sharp cheddar Cheese
1/2 cup sour cream
1 can condensed cheddar cheese soup
1/2 tsp salt
1 cup milk
1/2 tsp dry mustard
1/2 tsp black pepper

Directions:

Boil the macaroni in water for six minutes and drain.  In a medium saucepan, mix butter and cheese.  Heat over medium high heat and stir until the cheese melts.  Spray your slow cooker with non-stick cooking spray.  Combine cheese mixture, sour cream, soup, salt, milk, mustard and pepper in your slow cooker.  Add the drained macaroni and stir again.  Cook on low for 2 to 2 1/2 hours, stirring occasionally.
