Sugar Free Keto From – Mars Bar recipe

Share This Recipe

Before jumping to the recipe please note that the below information contains HOT TIPS for this recipe. We try and answer all your questions to guarantee a perfect keto recipe every time.

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 (US alternatives also include are Fibre Yum, Allulose Syrup or Vitafiber).

  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.

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.

      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!

    • Joanna B says:

      Would caramel work with coconut cream?

      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!

      Do you think instead of making the caramel you could use fibre caramel syrup? I’m just thinking out of pure convenience!

    • Deanna Brookhouse says:

      Hi Megan,

      Thank you for your delicious Keto recipes, you are a star! One question can you point me in the direction of a silicon mould for the mars bars? I’m being strict and counting carbs so want the correct size but can’t find a 4cm silicon ice cube tray?

      • Megan Mad Creations Hub says:

        Hi Deanna, I go a silcone mould from House. However if you just get an ice cube tray you can have 2 for 1 if they are just a 2cm tray

    • Robert says:

      These look amazing! Just wondering what syrup to use now? Appears the fiber syrup is no longer available?? Thanks
