You may be asking yourself, ‘a cake in a crock pot?’ Yes, I know it might seem a little outlandish, but this dessert is so amazing you need to try it before you knock it! I am sure that you and your family have at least been out for dinner and ordered a molten lava cake for dessert. It usually comes out in a small, single serving bowl enough for everyone to have a bite or two. My Crock Pot Chocolate Lava Cake turns your entire slow cooker into a chocolate lava pool! This dessert goes a long way so that everyone can enjoy their own big serving!

CROCK POT CHOCOLATE LAVA CAKE

Have you ever had that one dessert where you know it’s too good to be true? This, my friends, is that dessert. This wonderful lava cake is so delicious and easy to make. All the ingredients are dumped right in and then the slow cooker does the rest of the work! Baking cake in the crock pot is one of the best ways to do it, because it will cook slowly and evenly. The combination of the fluffy chocolate cake and warm fudge hidden beneath makes for an unforgettable treat!

INSTRUCTIONS

Chocolate Cake

Grease the insert of a large (5 to 7-quart) crock pot with cooking spray. Mix the sugar, flour, unsweetened cocoa, baking powder, and salt together in a large bowl. Whisk in milk, melted butter, and vanilla until combined. Spread the batter evenly in the bottom of the greased crock pot insert. 

Fudge Sauce

Whisk both sugars and unsweetened cocoa together. Sprinkle mixture evenly over the cake batter. Carefully pour the boiling water evenly over the top. DO NOT STIR! Cover with lid and cook on high heat for 2 to 2 1/2 hours OR cook on low heat for 3 ½ to 4 hours. When a toothpick inserted in the center of cake comes out mostly clean it is ready. Turn off heat and remove the lid. Allow cake to sit for 15 minutes or until it has cooled down slightly. Serve warm cake with whipped cream and/or vanilla ice cream. Enjoy!

SERVINGS

This recipe yields 8 servings. For my family of 5 that is more than enough for all of us to enjoy a very healthy serving of dessert. Kale, and Kallen, always go back for a second round and there is always plenty for that. This is a great dessert to make for a small birthday celebration, or if you plan to have a couple of friends over for dinner!

TOPPINGS

Vanilla ice cream and whipped cream are my favorite toppings for this lava cake, but the sky is the limit! Top it with any of your favorite cake toppings such as: caramel sauce, sprinkles, chopped nuts, etc.
