Peppermint Fudge Squares

This is the easy fudge every grandmother in the Midwest seems to have a copy of. No candy thermometer, no soft-ball stage, no beating until it loses gloss. Just boil milk, sugar, butter, and salt for exactly 5 minutes, then stir in marshmallows, chocolate chips, mint extract, and walnuts off the heat. The miniature marshmallows are the magic: they melt into the hot sugar mixture and stabilise the fudge so it sets smooth and creamy without the precise crystallisation control real fudge requires.

The peppermint flavour is gentle by design. A half teaspoon of mint extract perfumes the fudge without overpowering the chocolate; it reads as a faint cool finish rather than a candy-cane wallop.

The 5-minute boil is the only timing rule worth getting exactly right. Stir constantly to prevent scorching, and use a kitchen timer rather than guessing. Under 5 minutes and the fudge stays too soft to slice; over 5 minutes and it sets up grainy.

Pro Tips

• Use a heavy-bottomed pot. Thin pots create hot spots that scorch the milk and sugar before they can come to a proper rolling boil.
• Stir vigorously when the marshmallows go in. The mixture needs to be smooth before it cools; lumps of unmelted marshmallow set into bumps in the finished fudge.
• Line the pan with parchment paper or foil for easy removal. Greased bare pan works but parchment lets you lift the whole block out for clean cutting.
• Chill at least 4 hours before cutting. Warm fudge slumps; cold fudge cuts into clean squares.

Variations

• Substitute almond or vanilla extract for the mint for different flavour profiles.
• Use pecans or hazelnuts in place of walnuts.
• Top the warm fudge with crushed candy canes for visible peppermint flair before chilling.
