Sugar Free Keto From – Mars Bar recipe

Sugar Free Keto From – Mars Bar recipe

Share This Recipe

Well I guess if anyone was to attempt a great version of a Keto Mars Bar I would begrudgingly put up my hand…. YEAH RIGHT!  

It is perfection!  Truly keto confectionary at its best.  To be honest I barely can tell any difference from the keto Mars Bar to the original.  

If you have tried my various protein bars… Vanilla Nougat Bar, or my Chocolate Caramel Slice, you will know that I love recreating old school favourites with the Sukrin products.  On the ketogenic diet you do not have to give up sweets. You just need to learn how to make them sugar-free.

If you need to stock up I totally recommend the Bakers Pack, Sukrin put the pack together just for us and I gave it its name lol.  The pack contains all the ingredients I use in this recipe and my many other recipes.

How to make a Keto Mars Bar

There are a couple of specialty ingredients you will have to buy to make this recipe work. Those being Whey Protein Isolate and Sukrin Fibre Syrups.

  1. I choose to use Isopure WPI as it has a neutral flavour, no carbs and works perfectly in each of my recipes. Substitute a pea protein isolate for dairy free or other WPI’s. Add the protein powder by the tablespoon and mix well. Many other protein powders are more absorbent and can make the mix drier or crumblier.
  2. Sukrin Australia is the only retailer of Sukrin products. The syrups both in clear and gold are a great substitute for honey or glucose syrup and maple syrup or golden syrup. I also love the range of other sweeteners including a fabulous icing sugar substitute Sukrin Melis, and the Sukrin Gold granular, which is a rich caramel flavoured sweetener similar to brown sugar. You can order through this link here.
  3. Vitawerx Milk Chocolate is absolutely delicious! Available in both milk chocolate and white chocolate it is as close as you can get to eating the real thing but with ZERO sugar. Use the links here to purchase online.

This keto Mars bar recipe has been created to be included in an up-coming book Keto Eats that is available now for sale.

I have decided to put this keto Mars Bar recipe out on the website as there is currently nothing quite like this recipe and so many on my lovely Facebook community gave it a huge thumbs up to go ahead and make it.

The Keto From-Mars Bar

This was such an easy recipe for me to create. It is totally delicious and seriously tastes just like the real thing.... well at least to someone who wasn't a big consumer. I hope you love this recipe.

Chocolate Nougat



I used a silicone bar mould that is now expired. A silicone large icecube tray would be perfect for 32 x 4cm mars bites.



    • Place clear syrup and chocolate in large pyrex bowl and microwave for 1 minute. Stir to combine and melt chocolate.
    • Combine chocolate mix with WPI and MCT oil and mix until combined. With a gloved hand massage mix until it is no longer grainy.
    • Spoon or break off pieces and push into moulds (will make 32 x 4cm moulds)
    • Reserve.


    • Place all caramel ingredients into a large pyrex bowl. Heat on high for 3 minutes. Carefully remove from microwave stir mixture and return to microwave. Continue to heat at 1-2 minute intervals until mixture looks very bubbly when you take out and when stir becomes thicker and more viscose. At this point you will definitely smell a caramel scent.
    • Carefully spoon the hot caramel into your moulds. Refrigerate until set.
    • Melt chocolate and thinly coat each mars bar.


    1. At this point there is no keto alternative available in Australia for Sukrin fibre syrup products. I make these recipes with the products because I can easily replicate many recipes that previously would have been created with sugar products. The main ingredient is Isomalto oligosaccharides in the syrups, a sugar alcohol that passes through the body undigested. These products contain very little carbohydrate and low calorie.
    2. Chocolate, for the Milk Chocolate you can use any of the following 0 sugar varieties Sukrin Milk, Vitawerx, or Well Naturally. Each of these brands offers a low carbohydrate, no sugar at all, and low calorie option.
    3. The bars are best stored in an airtight container in a cool dry place. If refrigerated you will find that they are a lot harder, just like the real thing if stored in fridge or freezer.
    4. All keto sweets should be a sometime food. This recipe could easily be made into smaller portions, or drops similar to a Rolo.
    5. Please use caution when making the caramel. The instructions for the microwave are open in time as many microwaves have different wattage. In mine at 750W I find the caramel takes around 8-10 minutes. As it starts to get a little thicker you will notice if you check your spoon after 30 seconds you can gauge what "ball" or setting stage your caramel is at. For your convenience I have included a video to show you the look and feel the caramel has when it is ready to pour.
    6.  It should be noted that due to Sukrin labels including net carbs on the label this recipes carbs are calculated as net carbs per portion.

    1. hi this looks fantastic… I dont use protein isolate, what can I use instead please??? I really want to make this!!!

      1. You can try a pea protein, or a whey. But there is no other substitutes in this recipe for protein powder

    2. I so hope I have enough Sukrin fibre gold left to make these on the weekend.
      Megan you are amazing.

        1. Let me know what you think and give it a rating when you taste it Suzanne
    3. Can you make it without the sukrin fiber and substitute another liquid?!

      1. In Australia we have nothing similar that is a keto product

    4. I made these and they are just soooooooo good. I used Lindt 90% dark chocolate for coating the bars and I love them 😍

      1. Glad you enjoyed them. The dark chocolate would cut a little of the sweetness as well

    5. This looks amaze! I’m hoping we have products here in nz to create these xx

    6. Hey Megan,

      Just wondering what flavour of Isopure is best? Especially if I were to use this for other recipes.

      1. I just use the unflavoured one.

    7. I’m not on a keto diet but trying to get back to paleo lifestyle. My question is if honey would work instead of the syrup?

      1. I am not sure Lin sorry. Honey is definitely not as thick as the fibre syrups.

    8. Seriously these Mars Bars look so darn good!! The photography is perfect and I want to go out right now and buy the ingredients to make them. Yum and yum and some more yum. Nice one Megan! Love the video and your Aussie accent!!

      1. Hahaha! I am about as Aussie as they come aren’t I. Lol. I am such a dag. Thanks Adrianne

    9. Oh, yeah. Amazing! I got my baking pack from Sukrin and made these IMMEDIATELY. I coated them with 1/3 Lindt 90% and 2/3 Well Naturally milk choc. I also had chocolate flavoured Whey Protein which worked well. Thank you!

    10. Would caramel work with coconut cream?

      1. Yes it would Joanna

    11. Hi, I finally purchased the Isopure Whey Protein Isolate to makes these, only to realise that I don’t have MCT oil. Can you use melted coconut oil instead? Thanks!

      1. You can however if it is a firm set coconut oil it will make the nougat harder

    12. My nougat and caramel turned out perfectly! My coating on the other hand is what I’m struggling with 🙁 how do you melt the chocolate and coat the bars? Thanks for any help 😄

      1. I melt mine in the microwave for about 90 seconds then either dunk it or drizzle over

    13. What moulds did you use?

      1. The ones I used were by Chefs Toolbox
