If you like creamy, sweet potatoes with a buttery like texture, then cooking them in the slow cooker is for you! Sometimes I feel like when I cook my sweet potatoes in the oven, they don't quite get soft enough. This method in the slow cooker is not only incredibly easy, but they turn out so good they literally almost melt in your mouth. So rinse, and put 4 in a slow cooker and cook on low 6 to 7 hours depending on size. I'm telling you smooth, creamy, sweet, mmmmmmm!
