Chocolate Lava Cake You Can Make in the Slow Cooker

Made with pantry staples and chocolate chips, this chocolate lava cake comes together in one bowl and cooks right in the slow cooker. A simple cocoa and sugar topping plus hot water create a warm, fudgy sauce underneath while the cake bakes on top. It’s an easy, hands-off dessert that’s ready to serve with a scoop of ice cream when you want something rich without turning on the oven.
