Put raw boxed chocolate cake mix in a slow cooker with these 3 ingredients. It’s the ultimate winter comfort dessert.

For a richer flavor, try using dark chocolate chips instead of semi-sweet. You can also add a teaspoon of vanilla extract or a pinch of espresso powder to the batter for an extra depth of flavor. If you prefer a more intense chocolate experience, consider using a chocolate fudge cake mix. To make it more festive, top the cake with colorful sprinkles or edible glitter before serving. For a nutty twist, mix in a handful of chopped walnuts or pecans into the batter.
