MY LATEST RECIPES

I got this idea from my sister Meredith. Her recipe starts with a cake mix and a box of pudding, but since I don’t have either of those on hand most of the time, I decided to make a Slow Cooker Chocolate Lava Cake from scratch.

SO EASY.

First, you spread your batter into the bottom of a slow cooker. Then, add a sugary topping. Finally, pour hot water over all of it.

No stirring! Cook on HIGH for 4 hours.

  1. Meggan, you’re a genius! I can’t tell you the last time I used my slow cooker, but this recipe makes me want to bust it out ASAP:) Great recipe xx

  2. Oh yes, Meggan. You’re absolutely right – I really DO need this in my life! In fact a big splodge right about now would be fabulous! :-)

  3. I made this a gluten-free vegan cake by substituting the flour with gluten-free all purpose flour, the milk with almond milk and the butter with Earth Balance margarine and it worked a treat! The only difference was the cooking time; it only took 1.5 hours and it was done! Thank you for this amazing recipe!

    • What a fabulous idea! Which almond milk did you use (unsweetened, vanilla, etc.)? I have a reader who is GF and I will definitely pass this along to him. :) Thank you so much Miriam!

  4. Hi, I’m making this right now. My mom is coming from Michigan to visit my family in Minnesota. She will be at my place in about 4 hours off the Amtrak train, so it will be all cooked when she gets here. I’m so excited for her visit. I have not seen her since Christmas.

    • Hi Naomi! Thanks so much for your note. My sister lives in Michigan (the Hudsonville area) and I have family and best friends in Minnesota, so I know that route well! I hope you both enjoy the cake. I might have to make it myself this weekend, sounds so perfect right now at 8:30 on a Friday morning. :) Have a fun weekend!

  5. I was able to double the recipe without changing the cooking time. I made this for a family reunion and it was a big hit. Everyone loved it!

    • Good info, thank you!! I REALLY want to make this again soon, now I know I should just go ahead and double the recipe. :) Glad everyone enjoyed it! Thanks Barbara!

  6. Did you use a smaller or larger size (diameter) slow cooker? 

    • Hi Brittany! I use a fairly large one but it’s oval in diameter. It’s a Cuisinart digital crockpot. It’s pretty big. If I can help with anything else, please let me know!

  7. Can this be put in a pan that fits inside the slow cooker?  I have a GoWise pressure cooker/slow cooker combo. It’s round and pretty deep. 

    • Hi Kathy, I don’t see why not. I’ve never tried it, but I feel like it would work just fine. Hard to mess this one up! Thanks for reading!

  8. 4 hours on high seems like a long time… Not a typo? 

    • Hi Charlene, it’s not a typo. However, it possible the cake would be done sooner than that. I did a quick search and Betty Crocker says their version takes 3 to 3 1/2 hours on HIGH. So, I will test it again and see if it’s done in 3 hours. Sorry for the confusion!

  9. Would I need to make any changes for a round 5 qt crock pot? Last time I made it I used a 7 qt oval crock and it was delicious. I want to make it again but have to use a different crock pot.

    • Hey there! I think you should be fine making the recipe as-is in a 5 quart. Making it in a 7-quart, it’s nowhere NEAR the top so there is no danger of overflow. And, it should take about the same amount of time. I need to make this again myself!

  10. I love that you this recipe does not use a boxed cake mix like many of the other recipes for lava cake do! I even removed 1/4 cup of the sugar from the cake ingredients because I figured it would somehow make it “healthier”, haha. Didn’t miss the sugar and served it with vanilla ice cream:) Perfect, excellent, delicious!!!!!!! Thank you for this easy recipe.

  11. Thank you so much for this superb recipe. Made it last night and it’s already been eaten. Absolutely delicious. It took two and a half hours in my slow cooker though. Will be one of my go to chocolate desserts from now on :)

  12. Hi Megan! I’m planning to make this very soon as it looks AMAZING!! just wondering what flour to use and what sugar (not the brown sugar…what is the other one?) Thank you! Kat x

    • Hi Kathryn! The flour is all-purpose and the sugar is granulated (aka regular, plain sugar). I hope this helps! If not let me know! Take care and thanks for giving the recipe a try. :D

  13. Brilliant! thanks for getting back to me ! Looking forward to making it amd sharing it my friends!

  14. Hello Meggan, I really want to try this recipe, but since I’m in school I only cook for myself. I have a 2Qt. round crock pot. Is there any way I can condense this recipe? Thank you!!

    • Hi Gabriella! I can put it on the list to test, off the top of my head I don’t know exactly. I don’t want to lie and give you the wrong information! But I will post my results as soon as I can… won’t be until February though. Sorry for the delay! Good luck in school, such a lovely time in life! :D

    • The wait is no problem. Thank you for taking the time to do this for me. Also, I will enjoy it to my fullest! Thank you once again! :D

  15. Sounds perfect! I will try on Thursday but have to take it for a 20 min ride and won’t be able to serve for at least 30 minutes after…. thoughts? Thank you!

    • Hi Barbara, I haven’t done this exact scenario so I can’t say for sure. But, I think you will be fine. Because you’ll be traveling, the crock pot will be turned off and the cake won’t keep cooking. Worst case scenario, you have a little less chocolate sauce than you otherwise would… but I don’t see that happening because the heat is off. As far as food safety goes, you’re good to go. Please let me know if you have any other questions. Thank you for the question! Take care and I hope you love the cake.

  16. Thank you for taking the time to respond  Meggan! Was mostly concerned about taste..
    I will try to remember to send you an update, I think it will be ok! :)

  17. Hi Meggan, can this recipe be doubled? I’d like to bring this to a Jack and Jill:)

    • Hi Geri, I haven’t made it doubled but I don’t see why not? I cut it in half and it worked really well. :) I might have a chance to test a doubled version this weekend… when is your event? Please let me know! Thanks Geri!

  18. Hi Meggan, it’s Saturday, I may give it a whirl, what’s the worst that can happen? We eat it ourselves 😀
