Dark chocolate, sweetened condensed milk, and chopped walnuts make this easy microwave fudge. After chilling, it cuts into rich chocolate squares with a walnut crunch.
Line an 8×4-inch pan with parchment paper, leaving enough overhang to lift out the fudge.
Place 300 g dark chocolate , chopped, and 397 g sweetened condensed milk in a microwave-safe bowl. Microwave in 20–30-second intervals for about 1 minute total, stirring thoroughly after each interval, until the chocolate has melted and the mixture is smooth.
Stir in 120 g raw walnuts until evenly distributed. Transfer the mixture to the lined pan and smooth the top with a spatula.
Refrigerate for at least 2 hours, or until firm. Lift the fudge out using the parchment paper, then cut it into 28 pieces.
Notes
Chocolate choice: Dark chocolate balances the sweetness of the condensed milk. Milk chocolate also works, but produces a sweeter, softer fudge.Clean slices: Cut the fudge once it is firm, wiping the knife between cuts to keep the edges neat.Storage: Keep in an airtight container in the refrigerator for up to 2 weeks. Freeze for up to 2 months and thaw in the refrigerator before serving.
