Molten Chocolate Cake

Slow Cooker Molten Chocolate Cake is one of my favorite indulgences! Rich molten chocolate cake is a divinely decadent cake with a rich and creamy chocolate filling in the center. The liquid center can be chocolate, caramel, or any kind of fruit filling. It also goes by the name chocolate lava cake, or lava cake, because of the warm, liquid center. Using a Crockpot makes it so easy to throw ingredients in and watch them transform into a beautiful layered dessert. Serve with whipped cream or a giant scoop of vanilla ice cream and you have a sinfully sweet treat that everyone will love!

Tips for Crockpot Molten Chocolate Cake

  • Follow the layering instructions outlined in the recipe card below. I know it seems strange to put the filling ingredients on top, but trust me on this. During the cooking process, the top becomes the outer layer of the cake and the bottom becomes a gooey, chocolate caramel filling. It magically reverses during cooking!
  • Be sure to follow the recipe exactly. The secret is not mixing the layers together, no matter how much you want to. Your Crockpot should look just like this photo below before putting the lid on to cook:

  • Molten Chocolate Cake slow cooks for 3 hours. I like the convenience of being able to prepare this cake ahead and time it so we are ready for dessert right when the 3 hours are up. This also makes it a great dessert to have for hosting a shower, book club, or Bunco night. Rich chocolate fragrance fills the whole house while it’s cooking, which is one of my favorite parts!
  • The ease and convenience of this recipe are a big bonus. Clean up is a breeze! Ingredients are layered in the slow cooker lined with parchment paper or a slow cooker liner, which keeps the sides from burning. If you have a slow cooker that tends to burn in one spot, you can place some aluminum foil under the parchment paper in that spot. Then the mess can all be crumpled up and thrown away when you are done.

How many stars would you give this recipe?


    1. You can double it, but you will need two slow cookers. It won’t cook correctly in one slow cooker with double the ingredients. Thank you for asking!

    1. I haven’t tried this before, so I’m not sure how it would work. I would be worried that the layers would mix together while sitting and it wouldn’t have the right consistency.

      1. If i prepare separately and put into individual Tupperware and assemble later, do you think that would work?
        Btw test running it tonight but subbing with gluten free cake mix & f/f lactaid milk!

  1. Love this! A great way to enjoy baked goods without heating up the kitchen. I’m excited to try it! Also great tip on lining the slow cooker with parchment paper — I love the liners but when we’re out of them I just resign myself to having to wash the insert. Great idea!

    1. I have never tried doubling it but I imagine that cooking time would be the same. Let me know how it turns out!

  2. 5 stars
    Excellent recipe!!!! My kids loves this cake very muchh. This cake is better also for for kids than others. Thanks alot!!!

    1. Yes, you can make this without the parchment paper if you prefer. Do spray the crock pot so it doesn’t stick to the sides. Thanks for asking!

    1. That’s a tough question. I think I would probably try white chocolate chips and caramel bits. The caramel bits can be found near the chocolate chips in most grocery stores. It sounds good – let me know how it turns out.

  3. I can’t wait to try this recipe. I’m going to use sea salt caramels instead of Rolos, I hope it works. I love chocolate, caramel, and sea salt together. Could you substitute a white cake mix with vanilla pudding and peanut butter chips? I love peanut butter and white chocolate together too.

    1. I am having the same problem! It is taking way longer. Good to know I didn’t mess something up!

    2. 4 stars
      it took about 5 + hours to cook!!!! I am thinking maybe you should tell us what size crockpot you used to have it cook in 3 hours!!!! although it took so much longer….it was quite delicious….I can’t wait to make it again…but this time I’m either going to have to start in many hours in advance or try a larger crock pot to do this recipe

  4. 5 stars
    You were the hit of the potluck! My crockpot might be bigger; I accidentally made a family-sized pudding recipe and barely had enough to cover the cake layer. My temp might be different as well — it needed about 3.5 hours on low to set to my liking.

    If anyone is on the fence about this, give it a go. Seriously, amazing. I was practically signing autographs and getting papped before the potluck was over. Thanks so much!

  5. No parchment paper, no problem..I just used cooking spray on the crock pot. In addition, I couldn’t find the Rolos, so I went with Carmel Kisses.. yes a lot of unwrapping but oh so worth it.. my family and friends raved, (and drooled) and begged for more.

  6. I cooked this exactly like the recipe. At three and a half hours it was still like soup. Continued on for another 30 minutes and still the same. I know crock pots are different but I would have thought that at least by 4 hours it would have set at least some, but it never did. Any suggestions on maybe what went wrong? We still loved it even though it was like pudding. Thank you very much.
