Low Carb, Moist Keto Lava Cake

Dessert on the keto diet is definitely a good idea if we use the right kind of low-carb flours and keto approved sweeteners.

My first dessert, I’ve ever made on my ketogenic journey was a one-minute chocolate mug cake brownie. I could eat it every day and still hit my macros perfectly.

After having such a great success with a keto dessert, I wanted to move forward and bake a low carb dessert. I searched for keto desserts and found plenty of keto alternatives for dessert.

I’m experimenting with lots of flours lately: coconut flour, almond flour, flax seed flour and I noticed they are very different and it is pretty difficult to sub one for another in the low carb recipes.

  1. Instructions don't mention where you add the cream or vanilla. I assume you mix it with the eggs, but you might want to explicitly state this.

  2. Is it really supposed to have 1 tablespoon of vanilla? Mine turned out so bitter that I had to throw it out. Such a waste of of good vanilla.

    • What sweetener are you using? Some of them turn out so bitter when baking them. Or maybe you used a stronger vanilla extract and it may need less depending on the quality of the product. Always taste the batter and adjust the ingredients.

    • Patti, I am so sorry it didn't work out for you. I just finished making some for me and for my daughter who are on keto, and they were absolutely delicious. In my experience with baking, what makes things bitter based on all the ingredients listed would be the cocoa powder. If you did not use a high-quality cocoa powder, or if you accidentally use just a little too much, or if you used dark instead of the regular, that will definitely cause your recipe to be bitter.

    • It's a homemade low carb ice cream recipe I found on Pinterest. There are also a few low carb ice-creams you can find at the store, but you have to carefully read the ingredient lists to make sure they are keto friendly.

    • Hello and thanks for your kind comment. I'm not sure about this because stevia sweetness differs from brand to brand. I am not a huge fan of how stevia tastes in baked goods.

  3. could anyone please tell me how much fat is in this marvelous recipe. I have a hard time eating enough fat.. the carbs are listed but not the fat intake.. Thanks Debbie

    • Hi Jill!
      You can use the same batter. Spoon into the muffin pans, filling each cup about 2/3 full. You will have to cut the baking time in half.

  4. This was super rich and delicious!! I had to remember to only eat half for my one serving! For those who got a bitter taste, try using 3 1/2 Tablespoons of Whole Earth brand (keto). I also cooked mine for about 18 minutes in my Breville at 350 set on the convection setting as well…I had a very slightly crispy top and as the cake started to settle, the middle thickened into a pudding…I made my own whip cream by using 1/2 cup heavy whipping cream and 1 tsp maple extract. Cravings vanquished – incredible!

  5. Mighty good cake for sliced fresh strawberries! Topped with whipped cream of course. I bake at 400 for 9 minutes. Finishes setting up out of the oven. Perfect.

  6. I made this and it was delicious! My husband was very impressed he couldn’t believe it was sugar free and 4 grams or carbs. We had dessert first! Haha yum!

    • Hello Randy! There's a print button in the recipe card. Just scroll until you get to it. I guess you'll have to use a computer. Thanks for stopping by!

  7. Someone has to tell me where I went wrong mine taste terrible. The only thing I'm thinking it could be is Stevia packets…. I reduced the vanilla from 1tbsp to one 1tsp and it was still VERY bitter. I have this twice and both times it was horrible. Once exactly by the directions and the other reducing vanilla…. Stevia can't be that bad with baking right? (New to Stevia/low cal sweetener)

    • Hello dear. I don't use stevia for baked goods. It gives them an extremely bitter taste, it tastes almost like metal. I am not a fan of stevia, I use erythritol instead. Monk fruit sweetener is also great for baked goods.

  8. Loana, I only have Hershey's cocoa. Is that a sufficient choice for cocoa? Also, I only have Swerve sugar. Do you have any idea if that sugar supplement works well in baked goods? Thanks for your time,
    Tina

    • Hello Tina. Swerve is perfect for as a low carb sweetener for baked goods. And the Hershey's cocoa is good as long is unsweetened (has no sugar added). If you try the keto lava cake, let me know how it turned out!

  9. I just made this as a treat for my husband and I and I must say I was VERY skeptical but they were so yummy!! I used two tablespoons of monk fruit and a few drops of liquid stevia. I also only used one teaspoon of vanilla (because I totally read the recipe wrong ) and they were really good. Thank you!!

  10. I just made this and it was phenomenal. I calculated macros for my particular ingredients used and it came out to be 1.2g net carbs per serving. I ended up serving it with a small scoop of no sugar added vanilla ice cream and drizzling with some all-natural peanut butter. My husband gobbled it up in no time. I would recommend this recipe to anyone!

  11. Quick question, before I make this, are you using the words cocoa powder and cacao powder interchangeably? I have both, which one should I be using? Thanks so much!

  12. My new favorite cake recipe. Was a little surprised that there is no flour in it. I microwaved it for 60 seconds like stated in a previous comment. It puffed up and was so moist, chocolately and sweet. I added a few sugar free chocolate chips on top. Delicious! Next time I will try to bake it. Definitely a keeper for recipes . Thanks for sharing.

  13. Hello, I would like to make these for a Christmas party THIS Tuesday! My question is….can I make the batter ahead and put in ramekins (or mason jars?) and store in fridge the evening before and then bring to room temp (or not?) and bake on Tuesday??

    • I haven't tried making the batter ahead for the keto lava cake. I guess it should work though. It takes like 5 minutes to combine all the ingredients. If you try it let me know how it turned out 🙂
