What You’ll Need for Rocky Road Fudge

- 3 cups (16 oz/454 g) semisweet chocolate, chopped (use high-quality chocolate for best results)
- 1 (14 oz) can sweetened condensed milk
- 2 tablespoons (1 oz/30 g) butter (unsalted preferred)
- 2 cups (6 oz/170 g) marshmallows, roughly chopped (mini marshmallows work too)
- 3/4 cup (4 oz/115 g) roasted salted peanuts, roughly chopped (substitute with almonds or walnuts if preferred)
How to Make Rocky Road Fudge in the Microwave
- Prepare the pan: Line an 8×8 inch baking tray with parchment paper, leaving some overhang for easy removal.
- Melt the chocolate: In a large microwave-safe bowl, combine the chopped chocolate, sweetened condensed milk, and butter. Microwave for 1 minute, then stir. Continue microwaving in 30-second intervals, stirring gently, until the chocolate is fully melted. Tip: Avoid over-stirring to prevent separation.
- Add mix-ins: Gently fold in the chopped peanuts and marshmallows until evenly distributed.
- Set the fudge: Pour the mixture into the prepared baking pan and smooth the top with a spatula.
- Chill: Transfer the pan to the refrigerator and let it set for 3-4 hours, or until the fudge is firm enough to cut.
- Serve: Cut into small squares and enjoy! Store leftovers in an airtight container in the fridge for up to 2 weeks.
Perfect Pairings: Serving Suggestions
This Rocky Road Fudge is a crowd-pleaser on its own, but you can elevate it further by serving it with a scoop of vanilla ice cream or a drizzle of caramel sauce. For a cozy treat, pair it with a cup of hot cocoa or coffee. It’s also a great addition to dessert platters for parties or as a sweet gift in a decorative box.
Storage Secrets: Keeping Your Fudge Fresh
Store your fudge in an airtight container in the refrigerator for up to 2 weeks. If you’d like to keep it longer, it freezes beautifully! Wrap individual pieces in parchment paper and place them in a freezer-safe bag for up to 3 months. Thaw in the fridge before enjoying.
Quick Tips for Microwave Success
To avoid overheating the chocolate, stick to the 30-second intervals and stir gently. If you don’t have a microwave, you can melt the chocolate mixture in a double boiler on the stove. Just keep the heat low and stir occasionally to prevent scorching.
Fun Variations to Try
Switch up the mix-ins to suit your taste! Swap peanuts for almonds or pecans, or add a handful of dried cranberries for a tangy twist. For a richer flavor, use dark chocolate instead of semisweet. You can even sprinkle sea salt on top before chilling for a sweet-and-salty finish.
Common Questions Answered
Can I use milk chocolate instead of semisweet? Absolutely, but keep in mind it will be sweeter. What if my fudge separates? Over-stirring can cause this, so fold gently. If it happens, try adding a splash of warm cream and stirring slowly to bring it back together.
