This easy Thermomix fudge is a recipe you can truly rely on. It sets beautifully, tastes incredible, and has a smooth, creamy texture. The hint of salt balances the sweetness and brings out that classic salted caramel flavour, without tasting too sugary.
Making your own fudge is very rewarding, but I've learned the hard way that a lot can go wrong (looking at you, microwave fudge!). After extensive testing in my Thermomix, I've finally perfected a recipe that doesn't stick to the baking paper, isn't grainy or greasy, and slices cleanly into neat little squares.
This recipe may use a few more ingredients than most, but every one plays a part in making the best melt-in-your-mouth fudge.

Recipe Ingredients

Notes on the key ingredients:
- Sweetened Condensed Milk: Nestlé is the leading brand in Australia, but supermarket home brands work just as well. For UK readers, the Carnation brand is labelled 'Condensed Milk' but it's the same thing. Avoid skim or light versions, as they won't set properly. You can also make your own sweetened condensed milk in the Thermomix from milk powder, sugar and butter.
- White Chocolate: Use white chocolate melts from the baking aisle - they melt smoothly and set well in fudge. Lindt white chocolate also works well in this recipe.
- Brown Sugar: Essential for the rich caramel flavour and golden colour.
- Glucose Syrup: You'll find it in a clear tub in the baking section.
- Golden Syrup: Adds depth and a hint of toffee flavour.
- Unsalted Butter: Stick to unsalted so you can control the saltiness of the final fudge.
- Salt: I use Maldon sea salt flakes. They give a delicate crunch and lovely visual finish when sprinkled on top.
Step-by-Step Directions
These step-by-step photos are here as a visual guide. You'll find all the exact times, temperatures, and quantities in the printable recipe card below.
- Step 1: Line a 20cm square tin with baking paper, leaving overhangs on each side to make lifting the fudge easier.
- Step 2: Add the sweetened condensed milk, brown sugar, butter, golden syrup and glucose to the mixing bowl.
- Step 3: Cook for 7 min/100°C/speed 3, without the measuring cup (use simmering basket or splatter guard on top).
- Step 4: Cook for another 12 min/Varoma/speed 3, without the measuring cup (use simmering basket or splatter guard on top). The mixture will thicken and turn a lovely caramel colour.
- Step 5: Add the white chocolate, vanilla and salt. Mix for 20 sec/speed 3, scrape down, then mix again for 10 sec/speed 3 until the chocolate fully melts.
- Step 6: Pour the mixture quickly into the prepared tin - it sets fast. Sprinkle with sea salt flakes. Cool for 20 mins, then chill for at least 6 hours (or overnight) before slicing.
Fudge Tips
Ensure The Baking Tin Is Lined Correctly: Line the baking tin with baking paper to prevent sticking. Leave overhangs at each end to make it easier to lift the fudge out.
Clean The Bowl Immediately: Rinse the Thermomix bowl as soon as you've poured out the fudge - the mixture hardens quickly and can be tricky to clean if left.
Weigh Ingredients Accurately: Precise measurements matter. Even slight inaccuracies can result in a fudge that's too soft or not set correctly.
Storage
Fridge: Store the fudge in an airtight container in the fridge for up to 10 days.
Freezer: Wrap each piece of fudge tightly in plastic wrap or foil, then place in an airtight container or freezer bag. Freeze for up to 3 months.
Frequently Asked Questions
Yes, you can use white sugar instead of brown. I tested it, and honestly, I couldn't tell much of a difference - the fudge still turned out smooth and delicious.
No, I don't recommend doubling this recipe. The volume of ingredients would come too close to the maximum capacity of the Thermomix bowl, especially when cooking at Varoma temperature. This can lead to the mixture bubbling over and cooking unevenly. For best results, make the recipe in two separate batches.
A standard 20cm square baking tin is ideal. Line it with baking paper and leave some overhang on two sides, making it easier to lift the fudge once it's set. You can use a glass or ceramic dish if that's what you have, but metal tins help the fudge cool and set a little faster.

📖 Recipe
Thermomix Salted Caramel Fudge
Equipment

Ingredients
- 395 g sweetened condensed milk, see notes
- 100 g brown sugar
- 100 g unsalted butter, roughly cut into cubes
- 20 g golden syrup
- 40 g glucose syrup
- 200 g white chocolate melts, see notes
- 1 teaspoon vanilla extract
- ½ teaspoon sea salt flakes, plus extra for sprinkling on top
Instructions
- Grease and line a 20cm square tin with baking paper, leaving overhangs at each end.
- Add the sweetened condensed milk, brown sugar, unsalted butter, golden syrup and glucose syrup to the Thermomix mixing bowl. Cook for 7 min/100°C/speed 3, without the measuring cup, using the simmering basket or splatter guard on top.
- Cook for a further 12 min/Varoma/speed 3, still without the measuring cup and using the simmering basket/splatter guard on top.
- Add the white chocolate, vanilla extract and sea salt to the hot caramel mixture. Blend for 20 sec/speed 4, scrape down the sides of the mixing bowl with a spatula, then blend again for 10 sec/speed 4 until the chocolate is fully melted.
- Pour the fudge mixture into the prepared tin and smooth the top. Work quickly, as it begins to set fast. Sprinkle with extra sea salt flakes. Leave to cool for 20 minutes on the bench top then chill in the fridge for at least 6 hours, preferably overnight, before slicing. Wash the Thermomix bowl immediately after so it's easy to get the fudge mixture off.
