Crockpot Chocolate Lava Cake Recipe

A warm, ooey, gooey chocolate cake with a melted marshmallow and chocolate chip topping, this crockpot lava cake is a decadent dessert that is just pure indulgence and comfort.

It’s the perfect option for busy days or low-key entertaining. It takes about 10 minutes to prepare and doesn’t require babysitting the oven, fancy decorating or any special techniques, yet it completely reminds me of a fancy chocolate soufflé that you’d have to order before the start of your meal at an upscale restaurant.

The ease and quick preparation of this recipe also makes it perfect for letting the kids help make.

We’ve made this crockpot chocolate cake a few times now and have made it from scratch and using a boxed chocolate cake mix. I’ve provided the instructions below (and in the printable recipe card) to make it both ways, so you can choose whichever method works best for you.

Now, I preferred my cake not too molten in the center – just a bit melty. You may want to check the center of your cake about 30 minutes from the end of the indicated cooking time and see if you want to continue cooking or if you’re happy with it. Just set the crockpot to warm until ready to serve.

Can I use hot water instead of hot milk? Yes, where the recipe calls for covering the cake batter with hot milk, you can replace it with hot water or even hot coffee. However, the cake texture will be slightly different as the milk contributes to the fudgey texture. Hot water or coffee will still give you a moist cake, but will lack some of the molten lava experience that the hot milk creates.

Can I double this recipe to serve more people? Absolutely! You will need to increase the baking time accordingly, 3.5 to 4 hours on high. 

Can you make this recipe gluten-free or vegan? Yes, make the appropriate substitutions (gluten-free boxed cake or gluten-free C4C flour, etc) and follow the rest of the cooking instructions, as directed below.

To make clean-up even easier, instead of greasing the crockpot you can line it with parchment paper or these disposable crockpot liners.

  • Crockpot <– This is the crockpot that I use the most often – it has a thermoshield which not only prevents little fingers from being burned if the kids touch the outside of the crockpot, but it’s also great for bringing along to potlucks. I also like that I can set the cook time on it, so if we end up taking too long playing outside (or running errands) I don’t have to worry about the food burning.
  • Measuring Cups and Spoons
  • Heat-proof Measuring Cup
  • Whisk or Electric mixer <– this is a great hand mixer if you don’t want to make the investment into a stand mixer

  1. For the recipe using the cake mix you have hot milk to pour over the cake but where do you use the additional 1 1/2 cups cold milk?

  2. Hi Rachel,
    I’m sorry for the confusion. It’s supposed to read “OR” as an alternative to the sour cream, if desired, and you can add some cold milk to the batter if you want a softer, “meltier” cake. I just amended the recipe notes to be more clear – thank you for bringing my attention to it 🙂
