Made with a blend of semi-sweet and bittersweet chocolate, sweetened condensed milk, real butter, and crunchy toasted walnuts, this easy creamy chocolate walnut fudge sets into velvety, sliceable squares without ever touching a candy thermometer.
Traditional boiled sugar fudge is notoriously finicky—if the humid weather is off or you stir the pot one degree too early, the entire batch crystallizes into grainy sugar bricks. In our test kitchen, we swapped two-hour sugar boiling for a low-heat emulsion of 60% bittersweet chocolate, semi-sweet chocolate, butter, and sweetened condensed milk.
By melting the chocolates gently over low heat and folding in warm toasted walnuts and pure vanilla off the burner, you get rich, confectioner-style fudge that slices like cold truffle ganache.

Key Ingredients (Overview)
- Semi-Sweet Chocolate Chips or Bars: Two cups (12 oz / 340g) provide classic creamy chocolate sweetness.
- 60% Bittersweet Chocolate: One cup (6 oz / 170g) of chopped dark chocolate balances the sweet condensed milk so the fudge tastes gourmet.
- Sweetened Condensed Milk: One 14-ounce (396g) can acts as both sweetener and creamy binder—never use evaporated milk.
- Unsalted Butter: Four Tablespoons (56g) cubed and melted in with the chocolate for a satin sheen and soft bite.
- Pure Vanilla Extract & Fine Sea Salt: Added off the heat to round out the dark chocolate flavor.
- Walnut Halves: One and 1/2 cups (170g) coarsely chopped and toasted in a dry skillet for 4 minutes until fragrant.
- Flaky Sea Salt: Optional finishing sprinkle on top for a sweet-and-salty contrast.
Start by Toasting the Walnuts and Lining the 8×8-Inch Pan
Raw walnuts straight from the bag can taste slightly tannic and soft inside rich chocolate. Toss your chopped walnuts in a dry skillet over medium heat for 4 to 5 minutes until golden and fragrant, then transfer immediately to a plate so they don’t scorch.
Line an 8×8-inch metal baking pan with two criss-crossed sheets of parchment paper, leaving a 2-inch overhang on all four sides—this parchment sling lets you lift the chilled block of fudge straight out onto a cutting board.
Having your pan lined and walnuts toasted before melting the chocolate is essential because the fudge begins thickening as soon as it leaves the stove.
Why Low Heat Is the Key to Glossy Fudge
When chocolate and sweetened condensed milk are heated too aggressively over medium-high flames, the cocoa butter separates from the cocoa solids and rises to the surface as an oily sheen. Melting everything over the lowest burner setting (or a gentle double boiler) and removing the pot when 90% of the chocolate is melted keeps the emulsion satin-smooth.
Culinary Insight: Three Secrets for Confectioner-Smooth Fudge
- Use an 8×8-inch metal pan: A 9×9-inch pan makes thin squares; an 8×8-inch pan yields thick, 1-inch candy-shop cubes.
- Warm the knife under hot tap water before slicing: Wiping a sharp chef’s knife dry after running it under hot water lets the blade glide cleanly through the chilled chocolate and nuts.
- Chill uncovered for the first hour: Letting the fudge cool in the fridge without plastic wrap touching the top prevents moisture droplets from spotting the surface.
How to Make Easy Chocolate Walnut Fudge
In a heavy saucepan over low heat, combine the semi-sweet chocolate, chopped 60% bittersweet chocolate, sweetened condensed milk, cubed butter, and fine sea salt. Stir constantly with a silicone spatula for 4 to 5 minutes until smooth and glossy.
Remove the saucepan from the heat immediately and stir in the pure vanilla extract and 1 cup of the toasted chopped walnuts until evenly distributed.
Scrape the thick, warm fudge into the parchment-lined 8×8-inch pan and smooth the top with your spatula. Scatter the remaining 1/2 cup toasted walnuts and a pinch of flaky sea salt over the surface, pressing them gently in. Chill in the refrigerator for 3 hours until firm, then lift out and slice into 36 squares.
The Final Result
Each square cuts with clean, sharp edges, revealing golden toasted walnut pieces suspended in velvety, truffle-rich dark chocolate.
Pack the squares into parchment-lined holiday gift tins or serve on a slate dessert board alongside espresso and peppermint bark.
Stored in an airtight container, this fudge stays fresh for 2 weeks at cool room temperature, 1 month in the fridge, or up to 3 months in the freezer.

Ingredients
Creamy Chocolate Walnut Fudge
- 1 and 1/2 cups (170g) walnut halves, coarsely chopped and divided
- 2 cups (12 oz; 340g) quality semi-sweet chocolate chips or chopped bars
- 1 cup (6 oz; 170g) 60% bittersweet chocolate baking bar, finely chopped
- 1 can (14 oz; 396g) sweetened condensed milk (not evaporated milk)
- 4 Tablespoons (56g) unsalted butter, cut into cubes
- 1/4 teaspoon fine sea salt
- 1 and 1/2 teaspoons (7ml) pure vanilla extract
- 1/2 teaspoon flaky sea salt, for topping (optional)
Instructions
- Line the pan and toast the walnuts: Line an 8×8-inch metal baking pan with parchment paper, leaving a 2-inch overhang on all sides. In a dry skillet over medium heat, toast the chopped walnuts for 4 to 5 minutes, stirring often, until fragrant. Transfer to a plate to cool slightly.
- Melt the chocolate and condensed milk: In a heavy medium saucepan over the lowest heat setting, combine the semi-sweet chocolate, bittersweet chocolate, sweetened condensed milk, cubed butter, and fine sea salt. Stir constantly with a silicone spatula for 4 to 5 minutes just until melted and glossy (do not let it simmer or boil).
- Fold in vanilla and walnuts: Remove the pan from the heat immediately. Stir in the pure vanilla extract and 1 cup (113g) of the toasted walnuts.
- Spread into the pan: Scrape the warm fudge into the prepared 8×8-inch pan and spread into an even layer with your spatula. Scatter the remaining 1/2 cup toasted walnuts and flaky sea salt over top, pressing lightly so they adhere.
- Chill until firm: Refrigerate uncovered for 3 hours until completely set.
- Lift and slice: Use the parchment overhang to lift the fudge block onto a cutting board. Using a sharp chef’s knife warmed under hot water and wiped dry between cuts, slice into 6 rows by 6 rows for 36 squares.

- Make Ahead & Freezing Instructions: Store cut fudge squares in an airtight container layered with wax or parchment paper at room temperature for up to 2 weeks, or in the refrigerator for up to 1 month. Freeze in a freezer-safe container for up to 3 months; thaw overnight in the fridge.
