Ingredients

For the fudge base

• 400g milk chocolate, broken into pieces
• 397g tin full-fat condensed milk
• 40g unsalted butter
• 1 tsp vanilla extract

For the marshmallow swirl

• 150g white marshmallows
• 1 tbsp milk

How to Make Easy Marshmallow Swirl Fudge

• Prepare the tin: Line a 20cm square tin with baking parchment, leaving some overhang so the fudge is easy to lift out later.
• Melt the chocolate base: Place the chocolate, condensed milk and butter into a heavy-based saucepan. Set over a low heat and stir gently until fully melted and smooth.
• Add flavouring: Remove the pan from the heat and stir in the vanilla extract. Mix well so it is evenly distributed.
• Prepare the marshmallow swirl: Put the marshmallows and milk into a microwave-safe bowl. Heat in short bursts, stirring each time, until melted and glossy.
• Assemble the fudge: Pour the chocolate mixture into the prepared tin and smooth the surface. Spoon the melted marshmallow over the top and gently swirl with a skewer.
• Chill: Leave the fudge to cool at room temperature, then transfer to the fridge for at least 2 hours until fully set.

Tips

Why is my fudge too soft?

Fudge that does not set properly is usually undercooked or contains too much liquid. Make sure you use full-fat condensed milk and chill it for long enough.

How do I get clean slices?

Use a sharp knife warmed in hot water and wiped dry between cuts. This helps keep the swirl neat and tidy.

Can I change the chocolate?

You can use dark or white chocolate, but the sweetness and setting time will change slightly.
