Fudge Recipe Australia: Easy Condensed Milk Chocolate Fudge

This Australian-style chocolate fudge is a rich, sliceable treat made with chocolate, sweetened condensed milk and a little butter. It is cooked gently on the stovetop, chilled until firm, then cut into small squares for sharing. Home-style versions vary, but this simple no-bake method makes a reliably smooth batch without a sugar thermometer.

Ingredients

Use a 20 cm (8-inch) square pan for 24 small pieces. Weighing the chocolate gives the most consistent result, as the volume of chopped chocolate can vary with the size of the pieces. Choose a chocolate you enjoy eating on its own; its flavour carries through the finished fudge.

3 cups (525 g) milk chocolate chips or finely chopped milk chocolate
1 1/4 cups (395 g) sweetened condensed milk, about 1 standard can
2 tablespoons (28 g) unsalted butter
1 teaspoon (5 ml) vanilla extract
1/4 teaspoon (1.5 g) fine salt
1/2 cup (60 g) chopped roasted almonds or walnuts, optional

Instructions

Prepare the pan. Line a 20 cm (8-inch) square pan with baking paper, leaving some overhang on two opposite sides so you can lift the set fudge out later. Smooth the paper into the corners. This takes about 5 minutes and avoids having to prise sticky fudge from the pan.
Measure and chop. If using a block of chocolate, chop it into small, similar-sized pieces so it melts evenly. Chop the optional nuts, too. Measure the condensed milk, butter, vanilla and salt before turning on the heat; this small bit of organisation helps prevent the chocolate sitting over a hot burner while you search for an ingredient. Allow about 10 minutes.
Combine over low heat. Put the chocolate, condensed milk and butter in a heavy-based saucepan. Set it over low heat and stir continuously with a heatproof spatula, scraping the base and sides as you go. The mixture should soften gradually, not sizzle or bubble. Continue for about 6–8 minutes, until the chocolate has melted and the mixture looks thick, glossy and evenly blended. The full stovetop cooking time, including the next step, is about 10 minutes.
Finish the mixture. Take the saucepan off the heat as soon as no chocolate pieces remain. Stir in the vanilla and salt. If using nuts, fold them through now. Avoid vigorous beating: incorporating lots of air can make the surface look uneven, and extended heating can make the chocolate seize or turn grainy. If a few tiny chocolate flecks remain, keep stirring off the heat for a short time rather than returning the pan to high heat.
Fill the pan. Scrape the mixture into the lined pan. Spread it into the corners and level the top with the spatula. Work promptly, as the fudge thickens as it cools. Tap the pan gently on the counter once or twice to settle obvious air pockets, taking care not to splash the hot mixture.
Chill until firm. Transfer the pan to the refrigerator and chill for 3 hours, or until the centre feels firm when pressed lightly. Keep the pan level while the fudge sets. If your refrigerator is crowded or runs warm, it may need longer; use firmness rather than the clock alone as your guide. Do not try to speed setting by putting a hot pan in the freezer, where the edges can freeze before the centre sets evenly.
Cut into squares. Use the paper overhang to lift the slab onto a cutting board. With a large, sharp knife, cut it into 24 pieces, wiping the blade clean between cuts if it starts to drag. For neat edges, warm the knife under hot water, dry it completely, and then slice. Allow about 10 minutes for lifting, cutting and arranging the pieces.

Tips

Use gentle heat. Chocolate can scorch on the base of a pan before the rest has melted. Keep the burner low and stir continuously, especially around the edges. If your stovetop heats unevenly, set a heatproof bowl over a saucepan of barely simmering water and melt the ingredients in the bowl, making sure its base does not touch the water. This indirect method takes a little longer but gives you more control.
Choose chocolate thoughtfully. Milk chocolate makes a sweet, creamy fudge. For a less sweet, more cocoa-forward result, replace up to half of it with dark chocolate; using all dark chocolate creates a firmer, more intense batch, so choose a smooth eating chocolate rather than a very bitter baking chocolate. Chocolate chips are convenient, while chopped bars often melt especially smoothly.
Measure condensed milk by weight if possible. Use the full 395 g can, not evaporated milk. They are different products: sweetened condensed milk is thick and sweet, and gives this quick recipe its structure. Evaporated milk is thinner and unsweetened, so it will not set the fudge in the same way.
Keep moisture away from melted chocolate. Make sure the pan, spatula and any bowl used are dry. Even a small splash of water can cause melted chocolate to seize into a stiff, lumpy mass. If the mixture looks oily or grainy, take it off the heat and stir gently; do not add water in an attempt to thin it.

Serving Suggestions

Serve the squares at cool room temperature, when the fudge is firm but not hard straight from the refrigerator. Arrange them on a small plate with coffee or tea, or include them on a dessert platter with fresh berries and plain biscuits to balance their sweetness. Because the pieces are rich, cut them small; a 20 cm (8-inch) pan gives 24 modest squares, and you can halve those again for a larger party platter.

For a simple gift, place fully chilled pieces in small paper cases and pack them in a food-safe box. Keep the box cool during transport, especially on a warm day, as the fudge softens when left in a hot car or direct sun. If serving after a meal, take out only the amount you expect to use and return the rest to the refrigerator promptly.

Variations

Rocky road style: Fold 1/2 cup (75 g) mini marshmallows and 1/3 cup (45 g) chopped roasted peanuts into the mixture off the heat. Let it cool for a few minutes first so the marshmallows keep their shape rather than melting completely. This makes the squares chunkier and adds a chewy texture.

Dark chocolate and orange: Replace half the milk chocolate with dark chocolate and stir in 1 teaspoon (2 g) finely grated orange zest with the vanilla. The darker chocolate cuts the sweetness, while the zest brings a fresh citrus note. Avoid adding orange juice, which can make the chocolate seize.

Salted nut fudge: Use roasted almonds or walnuts in the mixture, then scatter a small pinch of flaky salt over the top before chilling. The nuts add crunch and the salt gives a savoury contrast. Start with a modest sprinkle; too much can overpower the chocolate.

White chocolate version: Replace the milk chocolate gram for gram with white chocolate. White chocolate is softer and sweeter, so use a good-quality product and keep the fudge refrigerated until close to serving. Fold through 1/2 cup (60 g) dried cranberries or chopped pistachios if you like, but keep add-ins to roughly the same amount so the slab still holds together.

Storage and Reheating

Place the fudge in an airtight container, separating layers with baking paper, and refrigerate it for up to 2 weeks. Keep it away from strongly scented foods, as chocolate can pick up odours. For the best texture, let only the pieces you plan to serve stand at room temperature for about 10–15 minutes. This is a confection, not a dish that needs reheating; warming the whole batch can make it soft and sticky.

For longer storage, freeze the pieces in a sealed freezer-safe container for up to 2 months, with baking paper between layers. Thaw them in the refrigerator for several hours or overnight, still covered, to limit condensation on the surface. Then bring a serving portion to room temperature briefly if desired. As with other perishable foods, refrigerate the fudge within 2 hours of serving rather than leaving it out on the counter all afternoon. Discard pieces that have been left in warm conditions for an extended period or have become contaminated by serving utensils.

Frequently Asked Questions

Why did my fudge not set?

The most common causes are using the wrong kind of milk, changing the chocolate-to-condensed-milk ratio, or not chilling the slab long enough. Check that the can says sweetened condensed milk, and measure the chocolate by weight if you can. Chill for the full 3 hours, then give it more time if the centre still feels soft. A warm refrigerator or a pan much smaller than specified can also slow setting.

Can I make this fudge in the microwave?

Yes. Put the chocolate, condensed milk and butter in a large microwave-safe bowl and heat in 20–30 second bursts at medium power, stirring well after each burst. Stop when the mixture is almost melted and finish stirring off the heat so it does not overcook. Microwave power varies, so do not rely on one long heating time. Stir in the vanilla, salt and any nuts, spread it in the lined pan, and chill as directed.

Can I use evaporated milk instead of condensed milk?

No, not as a direct substitute in this recipe. Evaporated milk is unsweetened and much thinner, while sweetened condensed milk is concentrated and supplies both sweetness and the thick base that helps the fudge set. Using evaporated milk would require a different recipe and cooking method; adding sugar to it here does not reliably reproduce the same texture.

How do I stop the fudge sticking to the knife?

Make sure the slab is fully cold and firm before cutting. Use a large sharp knife, warm the blade under hot water, then dry it thoroughly before each cut. Wipe off any chocolate residue between slices. A damp knife can leave streaks or make the edges sticky, so drying the blade is as important as warming it.

Can I make the fudge ahead for a party?

Yes. Make it up to 2 weeks ahead and store it in an airtight container in the refrigerator, or freeze it for up to 2 months. If making it several days ahead, leave the slab whole and cut it shortly before serving for slightly neater edges. Keep it chilled until you are ready to set out a platter, and return any remaining pieces to the refrigerator within 2 hours.
