Keto-licious Sugar Free Chocolate Fondant: 4 ingredients, 15 minutes baking time and just 1.9g carbs per slice.
But let me warn you now: this one is for chocolate connoisseurs only. Extremely rich. Moist. Velvety. Decadent. Pure chocolate keto heaven.
All you need is no-added-sugar dark chocolate, eggs, butter and icing ‘sugar’. It takes about 15 minutes to prepare and 15 minutes to bake. The rest is waiting time. Yep, that’s the difficult part: actually stopping yourself from diving in and trying this mouth-watering fondant IMMEDIATELY.
Let me warn you now: don’t give in to temptation or you’ll feel very let down. You must let the Keto-licious Sugar Free Chocolate Fondant set for a few hours. Which isn’t a bad thing, come to think of it. You could enjoy a long walk, meet up with friends, curl up on the sofa with a good book or sip a glass of wine whilst watching your favourite TV series. Whatever you fancy. Just don’t have a sneaky taste of the fondant!
The Two Main Ingredients I use for the Keto-licious Sugar Free Chocolate Fondant.
The superstar and main protagonist here is obviously CHOCOLATE.
You know that on keto you must minimise carbs, so milk chocolate is a no-no. But please don’t just buy any dark chocolate. Most dark chocolate has added sugar, so check the label. Generally speaking, higher cocoa content chocolate has less natural sugar and therefore carbs. But you can’t assume that will always be the case, so I repeat: check the label.
My favourite chocolate is Montezuma’s Absolute Black 100%. It is too bitter for me to eat out of the box. But with added sweetener it’s a different story. Unfortunately, you’ll only find it on-line – at ridiculously inflated prices, or at Sainsbury’s. Needless to say that whenever I see Montezuma’s on offer I buy the entire stock on display! It may be that, in countries outside the UK, Montezuma’s is more readily available, but I just wouldn’t know.
The other key ingredient is ICING ‘SUGAR’.
If you want to make your own icing ‘sugar’ you can easily do that with erythritol and stevia. Check out my quick instructions HERE.
To make the Keto-licious Sugar Free Chocolate Fondant you need a bain marie (aka water bath, double boiler) to warm up the eggs over the hob. You also need two loaf moulds so as to create a water bath for the fondant. It is what allows it to bake whilst keeping it moist. I prefer silicone moulds, but sometimes I use Pyrex. It makes no difference, other than it is easier to extract the fondant from a silicone mould. Whatever you use, do remember to let the parchment paper overhang, as it will make the job of lifting the fondant out way easier.
Just one other thing. I cut the fondant into 10 slices, which may sound a bit stingy. Trust me. This Keto-licious Sugar Free Chocolate Fondant is so rich, I doubt anyone would be able to indulge with more.
Finally, don’t hesitate because you’ve read ‘bain marie’. It really is a piece of cake ;). And this fondant will definitely remove any chocolate craving you might have.
Enjoy!

- 220g unsweetened dark chocolate (I used Montezuma's 100% absolute black) - U.S. alternative HERE
- 110g unsalted butter
- 3 large eggs
- 3 tbsp Sukrin icing 'sugar' (U.S. alternative HERE) (or Make your Own)
- Lightly butter a silicone or oven-proof glass loaf mould (approx 20cm x 11cm).
- Use parchment paper to line the buttered mould, allowing for some overhang so the fondant can be lifted out easily later.
- Lightly butter the parchment lining as well.
- Pre-heat oven to 220°C static.
- Melt butter, chocolate and icing 'sugar' in a medium pirex bowl in the microwave, until smooth and glossy, then set aside.
- Hand-whisk whole eggs in a bain marie to warm them up, then remove egg bowl from heat and whisk on high speed until the eggs have doubled in size and have become frothy, with peaks forming when lifting the whisk.
- Leave the bain marie water on the hob until it reaches boiling point, then turn off the heat.
- Fold eggs into chocolate mixture (not the other way around) ⅓ at a time, using a large hand whisk. Don't over mix.
- Transfer the mixture to your prepared mould and then place it inside a larger mould.
- Pour the hot water from the bain marie into the larger mould (about 2cm height).
- Bake for 5 mins, then cover loosely with foil and bake for a further 10 mins.
- Remove from oven and let the fondant cool completely before refrigerating it in its mould for at least 3 hours.
- Once set, lift fondant out and transfer onto a serving dish.
- Enjoy it on its own, or with whipped cream or vanilla ice cream.

I gather you are not in the US, so am wondering what comparable name this would be called over here in the states? The reason I ask is that over here “fondant”, aka “rolled icing fondant”, is a sweet, dough-like, edible sugar mixture used for covering cakes (instead of spreadable frosting or icing, the fondant is rolled out thin like a pasta sheet and draped over the cake).
While I’m here, you wouldn’t happen to know of any recipes for keto/sugar-free, rolled icing fondant would you?
Hi, yes in the U.K. we refer to ‘fondant icing’ as a very sweet, stiff paste used for decorating cakes. ‘Chocolate Fondant’ is a small cake that’s quite soft and liquefies in your mouth with no need to chew – hence the name ‘fondant’, which means ‘melting’ in French.
Fondant icing is quite tricky as it’s made with sugar, water, gelatin, vegetable fat and glycerol. I wouldn’t know if there is a ‘keto’ version somewhere but, if there is, it won’t be anything remotely close to the real thing, and it would use a lot of sweetener, probably a sugar alcohol, which can cause gut issues if consumed in excess.
Is it moldable?
Not sure what you mean by that. Can you clarify?
Hi this looks great!!!! Just wondering could it be rolled out and put on a cake like fondant icing?
Thanks heaps,
Bri
No, I’m afraid not, Bri, you have to spread it with a spatula. P.S. Sorry about taking so long to reply..your comment went in my spam for some strange reason.
Hi there Antya,
From my isolated cottage, on the beautiful West coast of Scotland.
I just wanted to say ( on my first ever post to you ) that I think this recipe
is cruelty to chocolate lovers, who are keto followers…to have to wait THREE
hours to taste it, is just TOO much, so I’m off in to Glasgow, to look round the shops, to pass this time, to stop temptation, getting the better of me…I will let you know what I think of the ” Fondant ” after dinner…Thanks SO much for all your hard work in coming up with these fail safe recipes…back soon
Marion
Hahaha Marion. Hope it was worth the wait. And thank you for commenting. You made my day!
Well, Antya,I enjoyed my trip to Glasgow, ( 67 miles away from my cottage.. I REALLY did ” Step away from the fondant ” but I just kept thinking of the treat in store when I got back home.
As a chef, I knew it would improve after a few hours..& boy improve it did ! It was FABULOUS, awesome, gorgeous, & SO moreish, & yummy, I shall be making it again for the weekend ( Which might have to begin on a Tuesday in my home ! ) I had just ordered all the different Sukrin products,
as I’m type 2 diabetic, & they don’t raise my B.S at all.
They also taste lovely ( I bought mine from a company called Dolphin Fitness, on the web, as they were cheapest )
So I’m now off, to take a trip through your other recipes, to discover what else I can make. I’ve no doubt my lovely Husband, will be confused & wondering just why a full roast dinner, followed by the ” fondant ” is on the table, on a weekday…but needs must. Keep em’ coming, I’m happy to be an official taster xx
Your friend in food
Marion
Hi Marion! Loving your witty feedback!!! I have decided to make you my OIT (Official Independent Taster). If you fancy trying my new chocolate fudge, email me at antya(at)queenketo(dot)com, stating your home address and full postcode so I can post it to you.
I will do just that Antya…I shall also be sat under my letterbox from Thursday, with my mouth open..waiting for the postman, & I won’t be ” fudging ” from that position, till your parcel arrives !
Thanks for the message..now it’s time for you to get back in that kitchen xxx
If only I had a kitchen….been without for 7 weeks whilst my house undergoes a total refurbishment plus extension. Living in a building site is horrendous enough, never mind trying to keep posting recipes!!! All my ‘baking’ is being achieved with a table-top halogen oven, believe it or not. Anyway, fudge will be on its way as soon as I make a fresh batch (probably tomorrow). x
