Easy Chocolate Fudge - 4-Ingredient No-Fail Treat

Real fudge fails for one reason: the sugar crystallises and turns grainy. You can dodge that whole problem by starting with sweetened condensed milk, which is already smooth and will not seize on you.

This version needs four ingredients, one pan and a fridge. No thermometer, no marble slab, no beating until your arm gives out. You melt, you stir, you chill.

The texture lands somewhere between a truffle and a chocolate bar. Dense, a little soft at room temperature, and clean to cut once it has had two hours in the cold.

About the Ingredients

3 cups (510g) semisweet chocolate chips

Use chips, not chopped bars, if you can. Chips contain stabilisers that help the fudge set firm. If you only have bars, chop them fine and add two extra minutes of stirring.

1 can (14 oz / 397g) sweetened condensed milk

Full-fat, not evaporated milk. Evaporated milk is unsweetened and will give you a soft, grainy slab that never quite firms up.

2 tbsp (28g) unsalted butter

Salted butter works too. If you use it, drop the added salt to a tiny pinch. Margarine in a tub will make the fudge greasy.

1 tsp (5ml) vanilla extract

Real extract, not imitation, if the budget allows. Add it off the heat so the alcohol does not cook off and leave a flat taste.

1/4 tsp fine sea salt

Fine salt dissolves; flaky salt sits in visible specks. Skip it only if your butter is salted.

1 cup (120g) walnut halves, roughly chopped

Toast them for six minutes at 350F (175C) first if you want more crunch. Pecans or roasted almonds swap in one for one.

Step-by-Step Instructions

1. Line the pan

Line an 8×8 inch (20x20cm) pan with parchment, leaving overhang on two sides. A smaller pan gives thicker fudge, a 9×9 gives thinner squares.

2. Melt everything gently

Combine the chocolate chips, condensed milk, butter and salt in a heavy saucepan over low heat. Stir constantly for 6 to 8 minutes until fully smooth. You want a glossy, pourable mixture with no visible chip shapes left.

3. Check for smoothness

Lift the spatula and let it drip back. If you can still see tiny grainy specks, keep stirring on low for another minute. Grainy now means grainy forever.

4. Add vanilla off heat

Pull the pan off the burner and stir in the vanilla. It will smell sharp for a second, then settle into a deep chocolate note.

5. Fold in the walnuts

Stir in about three quarters of the walnuts, saving the rest. Work fast, because the mixture thickens as it cools.

6. Pour and top

Scrape everything into the lined pan and smooth the top with an offset spatula. Press the remaining walnuts over the surface.

7. Chill until firm

Refrigerate uncovered for 2 hours, or overnight for the cleanest cut. The fudge is ready when the centre feels firm and does not give under a light press.

8. Cut into squares

Lift the slab out by the parchment and cut into 36 small squares with a warm knife. Wipe the blade between cuts for sharp edges.

Delicious Variations

Salted peanut

Swap the walnuts for 1 cup of roasted peanuts and sprinkle flaky salt over the top before chilling.

Mint

Use 1/2 teaspoon of peppermint extract instead of vanilla and skip the nuts entirely.

Dark and orange

Use 60 percent dark chocolate chips and add 1 teaspoon of orange zest with the vanilla.

Melt it low, stir it smooth, and let the fridge do the rest. Cut a few squares for tonight and keep the rest cold for the days when you need something sweet in ten seconds flat.

👨🍳 Chef's Note: If your kitchen runs warm, chill the fudge for an extra hour before cutting. A cold slab cuts clean; a room-temperature one fights back. Sweet success, one shortcut at a time.
