Easy Keto Chocolate Fudge in a baking pan

A super easy Keto Chocolate Fudge recipe the whole family will love. Honestly, it tastes just like the real thing but is only 2g net carbs.

For many years I made some amazing fudge in a popular cafe in Newcastle. Sugar laden and very sweet. This easy keto chocolate fudge is likely to be a new love in your life.

It has amazing texture, flavour and of course in a quick and easy keto recipe.

Not as sweet as the fudge I made so many years ago, but in my opinion better in so many ways.

This is a recipe for a fabulous keto fat bomb that satisfies. You can also change it to suit your personal tastes or simply your mood at the time of making. Read on for more tips and alternatives.

The Ingredients

* Sugar free smooth peanut butter. I love the Mayvers brand from Woolworths. You can however substitute any not butter of choice.
* Sukrin Gold Syrup, there is not keto alternatives in Australia for this ingredient
* Whey protein isolate. I use Isopure. A plant-based protein isolate can be substituted.
* Dark chocolate. You can use 85% Lindt or a sugar free brand can be substituted for a 100% sugar free keto fudge recipe.


Not only is this recipe a delicious keto fudge recipe it is also the perfect keto fat bomb recipe as well.

For some delicious flavour variations here are a few suggestions.

  • Citrus zest. A little orange zest into your easy keto chocolate fudge will result in a tasty jaffa flavour.
  • Extracts. Using extracts like Maple, Raspberry, Coffee, or Vanilla would be a super delicious variety.
  • Vitawerx Milk or White Chocolates. Simply substitute the dark chocolate for either of these for a new flavour. Using the white chocolate will result in a caramelised white chocolate flavour similar to the Cadbury Caramilk.
  • After setting the fudge you can dip or drizzle and sprinkle with any of your favourite toppings or keto chocolates.

    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.

  2. 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

    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. 🤣

    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.
