Keto Fudge Sauce Ingredients

250 g (1 cup) whipping or thickened cream (will work with both US and metric measures). Coconut cream could be used for dairy free substitutes.

Gold Sweetener – used as a brown sugar substitute with less than the sweetness of regular sugar it lends a caramel undertone to the fudge sauce. You can substitute for sweetener of choice but some sweeteners may crystallise after cooling.

Gold Fibre Syrup – is a fabulous Golden Syrup alternative. It reacts very similarly to golden syrup in cooking and helps caramelise in this sauce.

2 tbsp butter – I use salted butter but ghee or coconut oil can be substituted.

200 g dark chocolate – I use Lindt 85 or 90% chocolate. Sugar free dark chocolate, or Zebra Vegan Chocolate can be used instead for a dairy free keto chocolate fudge sauce.

2 tsp vanilla extract 

Pinch of salt flakes – salt helps to bring out the flavour in chocolate.

How To Serve Keto Fudge Sauce

Delicious and rich there is so many ways to use this keto hot chocolate fudge sauce recipe.

  5. Mug Cake – Add a spoonful to your favourite 2 minute keto mug cake recipe for an oozy centre.

1. Lakanto Gold is a great choice for the sauce. It adds caramel flavour notes to the sauce and doesn’t make it overly sweet

    This would have to be the 20 or 30th time I’ve made this. It’s so silky and unctuous – a little is well enough. A jar lasts ages in the fridge. Extremely versatile and super easy to knock up in the Thermie.

    Whip up a big bowl of zucchini noodles with marinara sauce and pair it with this keto garlic bread for the perfect keto alternative to pasta night.

    Wow this hot chocolate fudge sauce is awesome. Not only is it super easy to make but it is so versatile. It’s like ice magic on icecream and makes the perfect hot chocolate with a dollop of cream in it. It’s super delicious and perfect for dipping strawberries in. I also loved in on the chocolate Bavarian pie on a dollop of cream.
    I can guarantee you will love this chocolate fudge sauce whatever way you choose to eat it
