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 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.

Notes

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!
