What is a chocolate lava cake?

Chocolate lava cakes also known as molten cake are uncooked single-serve chocolate cakes resulting in a liquid chocolate center. It is a delicious easy dessert to serve lukewarm with a scoop of vanilla ice cream on the side.

Keto lava cake 3 ways, runny, molten, or gooey

There are many ways to enjoy these low carb lava cakes. In fact, you can really play with the texture by adjusting the baking time of your recipe. Let’s see the different baking time options to choose from to achieve your favorite lava cake texture.

  1. Runny lava cake – for those who love a liquid runny chocolate lava cake. This option requires less baking, about 9 minutes. You want the top of the cake to be set but jiggly and soft to keep a liquid center. I recommend serving this recipe into the ramekin, don’t flip over a plate or the cake is very fragile and may break.
  2. Molten lava cake – this one is less runny than the previous one. You need to bake the lava cakes for about 10 minutes, until the borders and top of the cake are set, crackle less jiggly.
  3. Gooey lava cake – this texture is close to a moist chocolate cake, the center is not liquid but very moist and it makes this easier to serve on a plate. You need to bake the lava cakes between 11-12 minutes to reach this texture.

Keto lava cake a quick keto dessert

Keto lava cake is the perfect quick keto dessert to serve to your family and friends. Whether you’re on a keto diet or not everyone will love those molten cake with a delicious liquid chocolate center. All you need to make these simple keto desserts are a few ingredients:

  • Sugar-free chocolate – I love to use sugar-free dark chocolate sweetened with stevia. If you can’t find this where you live you can use 99% dark chocolate or 85% dark chocolate. This last option is sweeter and contains slightly more sugar and carbs er serve but still keto-friendly in a small amount.
  • Sugar-free crystal sweetener – erythritol, Monk fruit stevia blend, or xylitol. Read my review of keto-friendly sweeteners to learn some more.
  • Butter or dairy-free butter.
  • Eggs – regular size
  • Almond flour – I used fine almond flour but an almond meal will work as well.
  • Ground espresso – this is optional but love the flavor of this into my chocolate lava cake.
  • Vanilla extract or vanilla essence.

How to make the best chocolate lava cake?

As I mentioned what makes a lava cake perfect is the liquid chocolate center. In order to achieve that you must undercook the cake. My tips are:

  • Ramekin size – make sure all your ramekins have the same size. I recommend 4-oz ramekins for the recipe. If the ramekins are wider, you will get a thinner layer of batter in each ramekin and the cakes will cook faster.
  • Filling – fill each ramekin with the same amount of batter. You bake the lava cake all at once, if one has less batter it will cook faster.
  • Check the baking process – for a ramekin of my size, it should take 10 to 12 minutes to achieve the perfect liquid center. I recommend checking the lava cake after 10 minutes. It is ready when the center jiggles but the top is set, a crust has formed.

How to store your gluten-free lava cake?

This recipe serves 4 keto lava cakes so you probably wonder what to do if you want only one lava cake? There are 2 options:

  • Store in the fridge the uncooked lava cake – and bake the next day, it will be a bit longer to bake as it is straight out of the fridge.
  • Bake longer to set the center and freeze – it will make a delicious chocolate cake that you can freeze or store for 3 days at room temperature.

Keto lava cake

Keto Lava Cake, an easy recipe in single ramekins with only 1.2g of net carbs per serving.
Prep Time: 10 mins
Cook Time: 10 mins
Total Time: 20 mins
4 people

Ingredients

  • 3 ounces 99 % dark chocolate or sugar-free chocolate chips or any chocolate >85% cocoa
  • 3 ounces Unsalted Butter cubed, out of the fridge for 1 hour, or dairy-free butter
  • 3 regular Egg
  • 1/3 cup Erythritol eryrthritol or Monk fruit or xylitol (only 1/4 cup if stevia sweetened chocolate used!)

Instructions

  • Preheat oven to 180 C (350F). Grease 4 little ramekins (I used 4 oz ramekins) with a bit of butter. Set aside.
  • In a medium saucepan, place cubed butter and 99% dark chocolate (or any dark chocolate with more than 85%). Melt on low heat, stirring all the time to avoid the chocolate to burn. You can also melt the chocolate "au bain marie", this method consists of placing the saucepan over a bowl of boiling water to melt it gently. When the chocolate and butter are melted, remove the saucepan from the heat and set aside.
  • In a small mixing bowl, using an electric whisk, whisk the eggs and sugar-free crystal sweetener on high speed for 1 minute until foamy, fluffy, and lighter in color. Note: use 1/3 cup sweetener if your chocolate is unsweetened or 99%, otherwise if you are using stevia-sweetened chocolate or 85% cocoa chocolate, use only 1/4 cup sugar-free crystal sweetener.
  • Stir in (don't whisk!) the vanilla, ground espresso, and almond flour.
  • Gently pour the melted chocolate into the previous egg mixture, stirring at the same time to form the cake batter. Make sure the melted chocolate is not burning hot or it 'cooks' the eggs but if you follow the low-heat technique above that will not be a problem.
  • Fill the 4 ramekins evenly to make sure they bake at the same speed.
  • Place the ramekin onto a baking tray and bring the tray into the oven.
  • Bake for 9-12 minutes. The trick to creating a runny, lava center is to undercook the cake. After 9 minutes, you should have a runny lava cake, after 10 minutes a molten lava cake, and after 12 minutes a gooey chocolate cake. In any case, you can eat the cake but for a lava center, you must take it off the oven when the center of the cake jiggle and the border are slightly set. Simply practice to learn how long you need to bake your lava cake to reach your favorite texture.
  • Cool 2-3 minutes in the ramekin before serving - note that the cake keeps baking slightly when it cools down as the ramekin is hot. That is why you must remove the lava cake from the oven when the center jiggles to enjoy a runny lava cake.
  • Eat directly in the ramekin with a scoop of sugar-free vanilla ice cream on the side or upside down on a plate (careful the cake may break if its center is very runny!)

This recipe serves 4 lava cakes if you want to eat only 2 of them, you can store the uncooked lava cake in the fridge for 24 hours and bake the next day. Otherwise, you can bake the 2 extra lava cakes longer, they will make delicious keto chocolate cakes that you can store for 4 days or freeze and eat for dessert, snack, or breakfast.
Sweetener amount:
if you are using 99% dark chocolate or unsweetened dark chocolate make sure you add  1/3 cup sugar-free crystal sweetener. If you use sugar-free stevia-sweetened chocolate or 85% dark chocolate, these are already sweet so 1/4 cup of sweetener is enough!

  1. I’m not sure what I did wrong. I followed the recipe exactly and for some reason the cake basically separated in the oven and I was left with gooey lava cake on top and gelatinous almond mound on the bottom. Do you know what I could have done wrong?

    Thanks!

  2. Hola! Un placer me encantan tus recetas, pero en mi país consigo en chocolate oscuro de 70% se le agrega la misma cantidad?

    • 5 stars
      I made this recipe twice this week because it was such a hit with all my family and friends… Thank you Carine for the amazing recipes that make this lifestyle much more enjoyable

    • Any chocolate will work in this recipe but 705 chocolate is high in sugar I recommend 85% to keep the recipe keto friendly, Enjoy the recipes on the blog, XOXO Carine

  3. Hi, I love this recipe! Question regarding the flour? Is it only 3 tablespoons of superfine almond flour? I added extra since it was thin and not like your video. Thank you for the recipes!????

    • Yes the recipe is correct you barely need flour in a lava cake or it gets too ‘cakey’. The video make looks different but I can assure you there is only that amount of flour. Enjoy ! XOXO Carine

  4. 5 stars
    These were really good!!! I tried them with peanut butter in the middle and they turned out really delicious! What I liked about it is that it was so rich from the dark chocolate and the peanut butter helped balance out the sweetness. It was just perfect ????❤️

    • What a great idea! Nothing can beat chocolate and peanut butter. Thanks for sharing your ideas with me, XOXO Carine

    • I wouldn’t cook lava cake in the microwave, it will dry out significantly. But I didn’t try so let me know how it goes if you do. Otherwise try my keto chocolate mug cake recipe if you want a delicious microwave chocolate cake in 90 seconds. Enjoy the recipes on the blog, XOXO Carine

    • I don’t recommend splenda as it is an artificial sweetner not safe for keto diet. Plus, it won’t add texture to the cake and the recipe won’t work as well. Also note that you would need very few splenda to replace the sugar free crystal Monk fruit in a recipe. ENJOY ! XOXO Carine

    • I didn’t try the recipe egg free and I won’t recommend flax egg here. Enjoy the recipe on the blog, XOXO Carine.

    • I am happy you enoyed my recipe ! I confirm that 3 oz (ounces) are 85 grams based on google converter here. Thanks for spotting my mistake 🙂 I do all my recipes in grams and cups and use google to provide the US measurement and it seems right for now on.

  5. 5 stars
    Followed recipe as written. 95% Lindt Dark chocolate & classic Lankanto granulated sweetener. 350 degrees for 14 minutes in counter top convection oven gave a gooey center. Add the espresso! Can’t taste coffee, makes it rot her in flavor. So good!

    • I am so happy you found my blog and that you enjoy my keto baking recipes ! I can’t wait to see what you re making next. XOXO Carine.
