The absolute best Keto Lava Cake recipe we've had all year! Only 2 grams net carbs per cake.
At only 2 grams net carbs per lava cake, this is the perfect dessert that won't kick you out of ketosis.

You may be just starting out on Keto or you may have already lost a ton of weight and are now just maintaining. I don’t know YOUR Keto journey, but I do know THE Keto journey.

It usually starts out great but often gets derailed by a pan of brownies or a bag of Oreo’s.  It’s almost always our sweet tooth that gets us.  The next thing you know, you’re kicked out of ketosis and working your butt off to get back in so you can start losing again.

This is one of the main reasons why I have been focusing on desserts here at Ketowize.  I know they are the downfall of many Keto dieters (this one included), and the reason why so many of us fall off the wagon so frequently.

The BEST Keto Lava Cake Recipe I've Ever Made

The best keto lava cake with fork taking a bite.
No matter where you are on your Keto diet journey, having a good dessert recipe that can be made in minutes definitely ups your chances of success.

I’ve loved delicious lava cakes long before I had even heard of the Keto diet.  There is just something so decadent about that rich, moist chocolate cake filled with ooey, gooey lava that pours out on your first bite.

Besides my own children, it really is one of my favorite things on the planet.

And surprisingly, adapting my favorite lava cake recipe to a low carb version wasn’t too terribly difficult.

Sure, it took some trial and error, but the results are out of this world delicious.

Simple Ingredients Make A Delicious Keto Lava Cake

Ingredients for our delicious keto lava cake recipe prepped and laid out on the counter.
We cut out the sugar (which is heavy in the original version) and replaced it with Swerve erythritol-based sweetener.

The key to making our lava cake recipe actually low carb (there’s only 2 grams of net carbs per cake in our version) came from two important changes.

First, this is a flourless Keto lava cake recipe so there are no flours (including coconut or almond flour) anywhere to be found in here.  We’ve tried a few versions with almond flour and found they just didn’t taste at all like the real thing.

So, we took a cue from our Ultimate Double Chocolate Chip Cookie recipe – it is completely flourless as well – and skipped the flour completely.

The other major switch comes from swapping out the sugar with an erythritol-based sweetener.  We always like to opt for Swerve Confectioner’s blend as we’ve found it works superbly for baking.

Mixing The Ingredients - You'll Want To Do It Right

Mix the wet and dry ingredients separately for this recipe.
You will want to mix the wet and dry ingredients separately. This is an important step for making successful Keto Lava Cakes.

This is a really simple recipe but it’s easy to screw up if you don’t follow this step.

Begin by mixing all of the dry ingredients (cocoa powder, powdered Swerve, baking powder, and salt) together with a fork to remove the lumps and incorporate them completely.  Many people skip this part and wonder why their lava cakes turn out subpar.

In a separate bowl, beat the eggs with a whisk or electric mixer and then add the heavy cream and pure vanilla extract and mix until combined.

Next, combine the wet and dry ingredients together and mix until smooth before splitting the mixture between two greased ramekins or other small glass baking dishes.

Ramekins work great for this Keto Lava Cake recipe. Just make sure you grease them before pouring the batter in.

A Few Notes On Cocoa Powder

First and foremost, cocoa powder IS NOT the same as cocoa mix. You will find real cocoa powder in the bulk section, baking aisle, or organic section of the store or at your favorite online retailer. But, knowing this information is only the beginning.

Choosing the right unsweetened cocoa powder can make a big difference in the richness of your Keto lava cakes. Plus there are many added health benefits to using a high quality cocoa powder that you may not know about.

Cocoa Powder is Rich in Polyphenols. These are naturally occurring antioxidants linked to many health benefits, including reduced inflammation, better blood flow, lower blood pressure, and improved blood sugar and cholesterol levels.

Tip: You can easily determine the quality of a cocoa powder by comparing its fat content, located on the nutrition label.

High quality cocoa powder can mean the difference between a mediocre lava cake and a Keto lava cake you want to make over and over again.

Dutch Process or Natural Process? What’s the difference and why does it matter? You’ll generally find cocoa powder labeled as dutch or natural process in the store. And, while it may sometimes be a personal preference, there are some key things you should know to help you make an informed decision.

When baking, the type of cocoa powder does matter, because the acidity of the cocoa powder could be the only thing activating the leavening agent in the recipe.

For example, if the recipe calls for baking soda, natural cocoa powder is probably fine and possibly even necessary, because the acidity in the cocoa powder helps activate the baking soda. If the recipe calls for baking powder, then you’ll be able to opt for Dutch-processed cocoa powder.

Tip: For recipes that are not specific, locate the leavening agents. Baking powder means you get to go Dutch–if you want!

    After tasting the batter, I added one more tablespoon of Swerve Confectioner’s sugar. I used dutch processed cocoa. I loved the cakes, as did my non-keto husband. So yummy and quick, I will certainly make this again….maybe tomorrow.

      Took away my craving for chocolate. This is my new chocolate snack. Easy to make and taste exacty as it saids chocolate lava excellent.

  2. I’m looking forward to trying this. While I enjoy the little cakes made with almond flour, I wanted one with lower carbs. TBH though, everyone I’ve ever tried that use whole egg tasted like chocolate scrambled eggs. I’m hoping this one won’t!

  3. 5 stars
    Oh yes. We just devoured this rich and delicious chocolate lava cake. Easy to make as directed and my perfect baking time is 15 minutes. Definately will make again! Try it! It is not a keto flop of a recipe.

  4. Just a note I want to leave for some of your readers who may not have Dutch chocolate powder…for this recipe, 4 T of cocoa, add 1/8 tsp of baking soda..

  5. 5 stars
    Really great recipe. I modified a bit the second time I made it. I cut back on chocolate by 1 Tbls and added 1 Tbls of Erithritol. Really good.

    This came out sooooo good! I’m wondering is there a no flour vanilla option?? Thank you, I will continue making this.

  7. 5 stars
    Excellent just as written. I served this to my husband, garnished with confectioner’s swerve, raspberries and a mint sprig. It was delicious and I think I got more praise than I deserved, because it was so easy. Lots of “bang for the buck”! Thank you for this little gem.

    Make these. Now. Double the recipe. They are *that* good! I didn’t have powdered sweetener, so just used granulated sweetener and they turned out just fine. I did taste the batter and found it slightly bitter, but we tend to like our chocolate desserts that way. It was perfect with a small scoop of keto ice cream. They are also amazing reheated in the microwave for about 10 seconds if you bake extras.

    Why are you not eating these Right Now? B

  9. 1 star
    I made the recipe as is, but didn’t like it. I used regular cocoa powder and the finished result, though pretty, was very bitter. I doubt that I will make it again using Dutch cocoa powder, as I don’t want to waste the ingredients.
