Can I use a different sweetener instead of monk fruit blend?
Yes! You can substitute monk fruit blend with erythritol or stevia, just adjust the amount based on how sweet your substitute is.
What can I use if I don't have almond flour?
If you don't have almond flour, coconut flour works, but use only about a quarter of the amount since coconut flour is way more absorbent.
How do I store leftover Keto Chocolate Lava Cake?
Store leftovers in an airtight container in the fridge for up to 3 days. Reheat in the microwave but don't overcook it!
Is there a way to make this recipe dairy-free?
Yes! Swap the unsalted butter for coconut oil and the heavy cream for coconut cream and you'll have a great dairy-free version.
What can I serve with the Keto Chocolate Lava Cake?
This cake is amazing with whipped cream or sugar-free ice cream. Fresh berries on the side are great for a little contrast too!
Put your scientist hat on, please....the hubs is having some bad reactions to sweeteners, and because I have used several kinds and can't remember which I may have used in a particular recipe, do you have a recommendation for one that has the least side effects? He experiences a sore throat shortly after eating, and then gastro issues later. I'm guessing erythritol (swerve) is a culprit, but I've also used Allulose and a monk fruit/Allulose blend. Is it possible that all of them a problem?
It’s very possible all of those could be triggering him, but erythritol is the most likely culprit, especially with the immediate sore throat plus later GI issues. Allulose is usually better tolerated but can still cause digestive upset in some people. If you want the lowest-risk option to test, I’d try 100% allulose sweetener and see if his symptoms stop. Another option is 100% monkfruit sweetener (one that isn't mixed with erythritol or allulose).
Holy Moly, this is so amazingly good! You just made my life so much sweeter, thank you for your awesome recipes!
I have not found a good small dessert that had the right texture until this - so rich!!! I only ate 1/4 and put it away as a treat to savor over several servings - especially with the homemade whipped cream. I used allulose and it was wonderful - thank you!!!!! Love your channel. Your recipes appeal to non-ketoers too!
This literally is my favorite quick dessert to make. So delicious and easy to make!
Instead of the monk fruit blend, can you substitute swerve for it in all of your dessert recipes?
Yes, you can!
Would like your 20 minute ice cream maker name and your ice cream recipe. I don’t have social media, but have seen your channel on UTube.
here's my ice cream recipe: https://www.ketofocus.com/recipes/keto-vanilla-ice-cream/
I just tried this. It's insanely delicious. I sure I'll be making this weekly. I miss chocolate donuts and this will solve that craving. Didn't have to alter the recipe at all. Thanks!
Delish!!!! Ok so I have been on keto for a cool minute; but, this cake is great!! It’s easy to make but for the topping I made a whipped cheesecake topping (I couldn’t help myself). I also sub substituted half of the sweetener in the cake for half of sugar-free vanilla syrup used in coffee‘s. I feel like I am sinning... but I am not!
This is so delicious!!! Loved every bite! Just a quick question. Are the macros above calculated per serving or for the entire thing?
Macros are for two servings. So if you ate it all, then you would double the macros. I split it into two because I felt like it was caloric dense for those watching calories.
Anne, I love your recipes and I follow you on YouTube. Keep up the good work ?
I’m confused. It appears that this is a recipe for 1 serving when being mad but the nutritional facts say 2 servings. Am I missing something?
It's very caloric dense and rich, so that's why I decided to make it two servings. You can eat the entire thing if you want.
Me and my lady recently started keto and we had a hankering for some kind of dessert. This absolutely delicious and is everything that you expect in a lava cake. We will definitely be having this again in the future!
I also want to say that I love your website. I understand that ad revenue allows you fuel your passion of providing recipes and encouraging a different lifestyle; but the fact that it isn't blatantly loaded with ads is something that I really appreciate. I found you on YouTube a few weeks ago. Keep the fantastic recipes going!
