Ingredients You’ll Need
The beauty of this Old-Fashioned Black Walnut Fudge Recipe is in its simplicity and quality ingredients. Each element is carefully chosen to contribute to the luscious texture, deep chocolate flavor, and that signature nutty finish.
- Semi-sweet chocolate chips: These provide a smooth, rich chocolate foundation without overpowering sweetness.
- Sweetened condensed milk: Adds creamy sweetness and helps achieve the perfect fudgy consistency.
- Unsalted butter: Enhances the smooth texture and adds subtle richness.

- Salt: Balances sweetness and sharpens the overall flavor.
How to Make Old-Fashioned Black Walnut Fudge Recipe
Step 1: Prepare Your Pan
Start by lining an 8×8-inch baking dish with parchment paper or lightly greasing it with butter. This simple prep step ensures the fudge won’t stick and makes it easier to lift out for cutting once it’s set.
Step 2: Melt the Fudge Base
In a medium saucepan over medium-low heat, combine the semi-sweet chocolate chips, sweetened condensed milk, and unsalted butter. Stir gently and consistently so the mixture melts evenly without scorching. The smooth, glossy texture you’re aiming for is the key to that perfect fudgy bite later on.
Step 3: Add Vanilla and Salt
Once everything is melted and smooth, remove the pan from heat and stir in the vanilla extract and salt. These little flavor boosters help to round out the flavor profile, making the chocolate shine even brighter and keeping the sweetness in check.
Step 4: Fold in the Black Walnuts
Gently fold in the coarsely chopped black walnuts, spreading them evenly throughout the chocolate mixture. This step is where the classic character of the fudge truly comes alive, marrying that melt-in-your-mouth chocolate with the rustic crunch of nuts.
Step 5: Pour Into the Pan
Pour the rich fudge mixture evenly into your prepared pan. Use a spatula to smooth the top so every piece cuts neatly and looks inviting.
Step 6: Chill to Set
Place the pan in the refrigerator for at least 2-3 hours. This chilling period is crucial for the fudge to firm up properly, making it easier to cut while keeping that perfect fudgy texture.
Step 7: Cut Into Pieces
When fully set, remove the fudge from the fridge and lift it out using the parchment paper edges. Use a sharp knife to cut the fudge into small squares or your preferred size. Clean your knife between cuts for the neatest edges.
Step 8: Serve and Enjoy
Now the best part: diving into your homemade Old-Fashioned Black Walnut Fudge Recipe. It’s an irresistible mix of creamy, nutty goodness that tastes like a warm hug in every bite.
How to Serve Old-Fashioned Black Walnut Fudge Recipe

Garnishes
For an extra touch of flair, sprinkle a few finely chopped black walnuts on top just before chilling. You could also dust with a light sprinkle of cocoa powder or a pinch of flaky sea salt to add a delightful contrast to the sweetness.
Side Dishes
This fudge pairs beautifully with simple accompaniments such as a cup of rich coffee, robust black tea, or even a glass of cold milk. These drinks perfectly complement the fudge’s deep flavors and help balance its richness.
Creative Ways to Present
Try serving your Old-Fashioned Black Walnut Fudge Recipe on a festive platter with colorful garnishes like fresh berries or edible flowers for gatherings. Wrapping small fudge squares individually in wax paper makes charming gifts, too, perfect for sharing the love with friends and family.
Make Ahead and Storage
Storing Leftovers
You can store leftover fudge in an airtight container at room temperature for up to a week. Keep it in a cool, dry place away from direct sunlight to maintain its texture and flavor.
Freezing
If you’d like to keep your fudge longer, freezing is your best bet. Wrap pieces tightly in plastic wrap and place them in a freezer-safe container. The fudge can last up to 3 months frozen without losing its quality.
Reheating
Fudge is best enjoyed chilled or at room temperature, so reheating isn’t usually necessary. If you prefer it softer, a brief 10 to 15-second microwave zap can gently soften the fudge. Just be careful not to melt it completely!
FAQs
Can I substitute regular walnuts for black walnuts?
Absolutely! While black walnuts provide a distinctive strong, earthy flavor, regular walnuts or a mix can also create delicious results, just with a milder nutty taste.
Is this fudge gluten-free?
Yes, this Old-Fashioned Black Walnut Fudge Recipe contains no gluten ingredients, making it naturally gluten-free and suitable for most diets without gluten restrictions.
Do I have to use semi-sweet chocolate chips?
Semi-sweet chocolate chips offer a nice balance of richness and sweetness, but you can use bittersweet or milk chocolate chips if you prefer a different flavor profile.
How do I prevent the fudge from becoming grainy?
Melting gently over medium-low heat and stirring constantly helps keep the texture smooth. Avoid letting it boil or heat too quickly, which can cause graininess.
Can I add other nuts or ingredients?
Yes! You can experiment by adding pecans, almonds, or even dried fruit for a personalized twist on this classic fudge. Just be mindful of the texture balance so it stays creamy with a pleasant crunch.
