There are loads of keto fudge recipes out there but this one is pretty epic! No it isn’t a 3-ingredient recipe with keto condensed milk, but let me tell you this is the smoothest sugar free fudge you will try.

The recipe is very easy. So I know you will love it! Dump everything in a pan, heat, stir, wait until everything is smooth, pour it and set. Add any extracts or crunchy bits for the best keto Christmas fudge, or keep it rich and simple with sugar free dark chocolate for a sexy Valentine’s Day fudge recipe.

What You Will Love about this Recipe

  • VERSATILE – the thing I love most about this recipe is its versatility. Add extracts to flavor the fudge. Add chopped nuts, crumbled chocolate chip cookies, cocoa nibs, coconut… whatever you love to customise your fudge.
  • LOW CARB – using sugar free chocolate chips or keto chocolate and low carb sweetener keeps the fudge low in carbs.

The Ingredients

  • Sugar free Smooth Peanut Butter – I love Mayvers brand from Woolworths. You can however substitute any not butter of choice.
  • Fibre Syrup – I use Nothing Naughty Chocolate Fibre Syrup or Sukrin Gold Syrup. For any other suitable swaps you need to check the first ingredient in the syrup is fibre syrup (derived from tapioca, corn, or chicory) and not water. If the syrup you are considering has water as the first listed ingredient it is not suited to this recipe.
  • Whey Protein Isolate – not only does WPI add protein it helps to thicken and set the fudge.
  • Chocolate – use your favorite keto chocolate or keto chocolate chips in the fudge. I use Lindt, Lakanto, or Vitawerx. Try to avoid chocolate with maltitol or sucralose. Some keto fudge recipes use unsweetened cocoa powder. This recipe does not. Use the best quality keto chocolate you can.
  • Cream – use heavy whipping cream or thickened cream.

How To Make Keto Fudge

Butter sweetener and chocolate inside a Thermomix bowl.

Step 1. Place all the ingredients into a saucepan over medium heat (or into a Thermomix bowl).

Step 2. Cook stirring until the fudge mixture is thick and glossy.

Step 3. Pour into a parchment paper lined (or cling film) pan. Chill until set.

Step 4. Slice into individual portions. Store in the fridge or freezer in an airtight container.

Keto Friendly Fudge Flavors & Variations

For some delicious flavour variations here are a few suggestions.

  • Citrus zest. Make your keto chocolate fudge jaffa with a teaspoon of citrus zest, extract or a few drops of orange flavored oil.
  • Extracts or drops like Vital Zing Drops are a great way to flavour the chocolate. You can also use keto white chocolate, caramelised white chocolate, milk or dark chocolate to make delicious variations.
  • Peanut Butter Fudge – drizzle with sugar free keto peanut butter.


Can you freeze keto fudge?

Yes, you can. Store it in an airtight container in the freezer. Enjoy it straight from the freezer or defrost overnight in the fridge.

Can I make dairy free low carb fudge?

You can swap the butter for coconut oil and the heavy cream for thick coconut cream or a dairy free alternative.

Recipe Notes and Tips for Keto Fudge:
  1. Thermomix Method: To make this fudge in the Thermomix, ensure the ingredients used are as per the recipe. Follow the specified temperature and time guidelines for optimal results.
  2. Saucepan Method: If using a saucepan, stir continuously to prevent burning.
  3. Storage Tips: Store the fudge in an airtight container in the refrigerator for up to two weeks. For longer storage, individually wrap the fudge pieces in parchment paper and freeze for up to three months.
  4. Ingredient Swaps: Experiment with different sugar-free nut butters and chocolates to create various flavor combinations. Swap the whey protein isolate with your preferred protein powder for different nutritional profiles. For a variation, try using different sweeteners like erythritol or monk fruit sweetener. I use powdered erythritol. I find this sweetener results in a smooth grit-free fudge. 
  5. Roasted Smooth Peanut Butter: For a rich and nutty flavor, opt for roasted smooth peanut butter as it enhances the overall taste of the fudge.
With these tips and tricks, you can create a delectable batch of keto fudge, whether you choose to use a Thermomix or a saucepan. Enjoy the smooth, creamy texture and rich flavors without compromising your dietary goals!

    This is the best keto fudge, tastes great. I was hesitant at first because other keto fudge recipes promised but didn’t deliver, but this one is terrific. Definitely a keeper. Thanks!

    The combo of peanut butter and chocolate is always a good idea and the fact that there are barely any carbs in this is just the cherry on top! I love a good chocolate dessert and this fudge was delicious!

    I have so many family members on the sugar-free diet these days, I’ve been considering a keto dessert plate for holiday handouts this year. This fudge is so easy and yummy I’m definitely adding it to the list!

      Hi Megan…. what is the conversion of the fibre syrup? I thought it would be in mls as isn’t it a fluid? Please help as I’m really keen to make this fudge. Thanks so much.

      Can someone please respond to my question … thanks 😊
      Hi Megan…. what is the conversion of the fibre syrup? I thought it would be in mls as isn’t it a fluid and 140g seems a lot? Please help as I’m really keen to make this fudge. Thanks so much.

      1. Megan Mad Creations Hub

        Hi Mary, I use weights as they are most accurate. The syrup is heavier than water for cup measures. 140g is accurate for the recipe (it makes a lot of fudge as you can see) and that equates to around 110ml in a cup. If you are making it and have a set of kitchen scale simple place your bowl onto the scale. Tare the weight to zero and add the syrup. Considering the average fudge recipe has about 3 cups of sugar added this recipe is considerably reduced in sweeteners and sweetness.

    3. Mary Wood

      Hi Cathleen … I’m really desperate to make this fudge and have bought all the ingredients. I’m really puzzled by the amount 5 oz or 140g of the fibre syrup which seems a lot to me and also doesn’t seem right as it should be in mls as it’s a fluid. I’m sending this email to you as you say you’ve made it a number of times and l was hoping you could help me. Thanks Cathleen … Mary

    I really like it when I find classic recipes made for the keto diet that are as close to the original as possible, and this fudge did not disappoint!

    Thanks for this recipe, absolutely delicious and easy to make too. Going to make some more for gifts at Christmas.

  11. Arlene Baker

    I do not have the syrup. How can I increase the use of the Sukrin gold to accomodate not adding the syrup to the recipe? Am way excited to try this recipe, but don’t have the syrup. Have everything else..

    1. Megan Mad Creations Hub

      The syrup is to help it stay soft. Using only the granular will make it grainy when it is chilled I am sorry. Sadly, keto granular sweeteners have a tendency to recystallise.

  12. Robert Crick

    When heating all ingredients in a saucepan, how long should this take?? I don’t want to burn the ingredients, however on my first attempt at making this it came out a bit granular still? I thought maybe I didn’t heat (cook) for long enough?? Thanks

    PS: Re My prev comment about soft texture, I mean to add that I used the Thermomix (TM6) to make this recipe

  14. Anne-marie Mulligan

    GOLD SYRUP QUESTION: I’ve got the Sukrin Gold Syrup / Caramel and Syrup. Is this suitable for this recipe? Thanks in advance

    1. Megan Mad Creations Hub

      Absolutely yes it is.

        Thanks!! The taste of this is amazing. It is so smooth and a beautiful flavour combination. However, not sure what I am doing wrong as mine is very soft. It does not set hard enough to cut a square. It has been in the fridge for 24 hours. Mine is done in the Thermomix. I use xylitol for the sweetener. Thanks in advance.

    This fudge is amazing. It is in my fridge all the time. I have made it now so many times. My very fussy daughter loves it. It is so easy and makes the perfect gift 🎁 if you can bear to part with it. This is one bowl I just have to lick. 🤣

    1. Megan

      Thanks so much for the review Lucy. I am so happy that you enjoy this recipe

    So super easy and really delicious! We substituted Brazil, Cashew and Almond butter for the peanut butter and it’s beautiful. My five year old absolutely loved licking the spoon and then the top of the fudge in the tray LOL!!

    1. Megan

      So glad you and your little one enjoyed Tammy. I too am guilty of licking the spoon.

    How easy is this fudge to make and seriously it tastes like real fudge!!. I am going to have to ration the grandkids these school holidays so we have some left for ourselves.!!
    It’s so good knowing I can give them a treat that is sugar free. and it’s a nice treat for us to have with a cup of tea.
    This will be a favourite for sure.

    1. Megan

      Super happy it will pass the family “low carb” testing. Let us know what the kids really thought.

    Delicious. Subbed tahini for 75 grams of the nut butter as I only had 25 grams was delicious both hot and when set (cold)
    Could easily make but free by using all tahini

    Bloody delicious.
