Indulge in this creamy, no-bake rocky road fudge featuring a gourmet twist of nutty brown butter and a hint of espresso to elevate the classic chocolate, marshmallow, and peanut combination.
Line a 9x13 inch baking pan with parchment paper, letting a little hang over the sides like handles. Give the parchment a light mist of non-stick cooking spray so the slab lifts out cleanly later.
Set the pan aside within arm’s reach, because once the chocolate is glossy and ready, you’ll want to move quickly while it’s still spreadable.
Brown butter and espresso boost
In a small pan, brown 2 tablespoons of butter until it turns golden and smells nutty, then take it off the heat.
Stir 1 teaspoon of instant espresso powder into the sweetened condensed milk until it looks smooth and slightly tan.
Melt the fudge base
In a large microwave-safe bowl, combine the milk chocolate chips with the sweetened condensed milk mixture. Microwave for about 60 seconds, then stir slowly, scraping the bottom and sides.
Keep microwaving in 15 second intervals, stirring after each one, until the mixture is completely smooth and shiny.
Pour in the warm brown butter and stir until fully blended for a richer aroma.
Fold, press, and set
Let the chocolate mixture cool for a brief moment so it’s still fluid but not piping hot, then fold in the mini marshmallows and chopped peanuts.
Scrape everything into the prepared pan and press it into an even layer. Chill in the fridge for about 60 minutes to set.
Once firm, lift the fudge out using the parchment handles and cut into squares using a clean, sharp knife.
