Slow cookers are one of the hardest working tools in the kitchen. We call on them for making everything from warm winter soups and hearty barbecue pork to party-worthy desserts. They’re not only ideal for preparing weeknight dinners but also for whipping up festive beverages like hot chocolate.Take a break from microwavable instant mixes, and treat yourself to a rich homemade version of this winter drink. Everyone will want another cup of this Slow-Cooker Hot Chocolate. Whole milk and half-and-half make it ultracreamy, while the addition of dark chocolate chips amp up the chocolatey richness. Pour yourself a warm mug filled with this delicious treat, and garnish it with pieces of crushed hard peppermint candies and a handful of miniature marshmallows. Kick things up a notch with an optional shot or two of peppermint schnapps.
