This delightful confection has been a staple in New England kitchens for generations and remains a beloved favorite during the holidays, at bake sales, or as a thoughtful homemade gift. If you’ve been searching for a simple yet indulgent recipe that carries both nostalgia and sweetness, this penuche fudge recipe will not disappoint.
My recipe story
Growing up, penuche fudge was a recipe that always reminded me of family gatherings. My grandmother used to prepare it in a well-worn saucepan, carefully stirring the mixture until it reached the perfect temperature. I remember sitting at the counter, watching the sugar dissolve and smelling the rich aroma of caramel filling the kitchen. Over the years, I adapted her recipe slightly, ensuring it remained simple and foolproof. Now, it’s the kind of sweet I love making for friends, neighbors, or simply to satisfy a craving for something buttery and indulgent. Every bite of this fudge transports me back to those cozy kitchen moments where love was poured into every stir of the spoon.

Ingredient breakdown
The charm of penuche fudge lies in its simplicity. Unlike other fudge recipes that rely on cocoa or chocolate, this one leans entirely on brown sugar to deliver its distinct caramel notes. The brown sugar not only provides a warm color but also enhances the depth of flavor, making each bite taste rich and indulgent.
Butter and milk form the base of the recipe, creating the creamy texture that makes fudge irresistible. The butter adds richness while the milk helps dissolve the sugar and binds everything together. Vanilla extract is added at the end to provide a touch of aromatic sweetness, balancing the caramel tones perfectly. Many people also enjoy folding in nuts like pecans or walnuts, which add crunch and a nutty complement to the sweetness. The ingredients are few, but the flavors they produce are nothing short of delightful.
If you prefer a softer, melt-in-your-mouth fudge, stick with light brown sugar for a milder taste. For a bolder, more molasses-forward flavor, you can experiment with dark brown sugar. Either way, the result is a confection that feels homemade and timeless.
Equipment you’ll need
- Heavy-bottomed saucepan
- Wooden spoon or heatproof spatula
- Candy thermometer (highly recommended)
- 8×8-inch square baking pan
- Parchment paper or aluminum foil
- Sharp knife for cutting
- Mixing bowl
Step-by-step directions
Step 1: Prepare your baking pan by lining an 8×8-inch square dish with parchment paper or aluminum foil. Leave some overhang on the sides to make it easier to lift out the fudge later. Lightly grease the paper or foil with butter to prevent sticking.
Step 2: In a heavy-bottomed saucepan, combine the butter, brown sugar, and milk. Place the pan over medium heat, stirring gently until the sugar fully dissolves and the mixture begins to bubble. This step is crucial to avoid gritty fudge, so take your time here.
Step 3: Attach a candy thermometer to the side of the pan and allow the mixture to cook without stirring until it reaches the soft-ball stage, around 238°F (114°C). This ensures the fudge sets properly while maintaining a smooth, creamy texture.
Step 4: Remove the pan from heat and stir in the vanilla extract. If you’re adding nuts, now is the time to fold them in gently. Allow the mixture to cool slightly, about 5 minutes, before beating it.
Step 5: Using a wooden spoon, beat the mixture vigorously until it thickens and begins to lose its gloss. This can take 5–10 minutes. Beating incorporates air, giving the fudge its signature creamy consistency.
Step 6: Quickly spread the mixture into your prepared pan, smoothing the top with a spatula. Let it cool completely at room temperature until firm. Once set, lift the fudge out using the parchment paper overhang and cut it into squares.

Variations & substitutions
Penuche fudge can be easily adapted to suit different tastes. For a nutty twist, fold in chopped walnuts, pecans, or almonds. To make it more festive, you could sprinkle sea salt on top for a salted-caramel flavor or add a dash of cinnamon or nutmeg for warmth during the holiday season. If you’re dairy-free, substitute the butter with vegan butter and the milk with coconut milk for a slightly different yet equally delicious treat. Some adventurous cooks even like adding a splash of bourbon or rum for a grown-up version of this traditional fudge.
💡 Expert Tips & Troubleshooting
- Always use a candy thermometer to avoid undercooking or overcooking the fudge.
- If your fudge turns out grainy, it’s likely the sugar wasn’t fully dissolved—take extra time at the beginning.
- Beat the fudge until it loses its glossy shine; otherwise, it may not set properly.
- Don’t scrape the sides of the saucepan into the pan—this can introduce sugar crystals.
- For clean cuts, use a sharp knife and wipe it between slices.
Storage, freezing & make-ahead
Penuche fudge stores beautifully, making it perfect for planning ahead. Once cut into squares, place the fudge in an airtight container with layers separated by parchment paper. It will stay fresh at room temperature for up to 1 week. For longer storage, refrigerate it for up to 3 weeks. If you’d like to freeze it, wrap each piece tightly in plastic wrap, then place in a freezer-safe bag. The fudge can be frozen for up to 3 months. When ready to serve, let it thaw at room temperature for a couple of hours. This make-ahead option is especially handy during the busy holiday season.
Serving ideas & pairings
Penuche fudge makes a delightful treat on its own, but it can also be paired in creative ways. Serve it alongside a cup of strong coffee or espresso to balance its sweetness, or pair it with black tea for a cozy afternoon snack. For special occasions, arrange squares of fudge on a dessert tray with cookies and truffles for an elegant presentation. You can also crumble it over vanilla ice cream to add a caramel crunch or package it in decorative tins for thoughtful homemade gifts during the holidays. Its versatility makes it a treat worth sharing and savoring.
FAQ
Can I make penuche fudge without a candy thermometer?
Yes, but it’s trickier. You can test for the soft-ball stage by dropping a little of the hot mixture into cold water. If it forms a soft, pliable ball, it’s ready. However, a candy thermometer gives more consistent results.
Why did my fudge turn out grainy?
Grainy fudge is usually caused by undissolved sugar crystals. Make sure you stir thoroughly until all sugar is melted before boiling, and avoid stirring once it begins to cook.
Can I double this recipe?
Yes, you can double the batch, but be sure to use a large enough saucepan to prevent boil-overs. Keep an eye on the cooking temperature to ensure even results.
What type of brown sugar works best?
Both light and dark brown sugar work well. Light brown sugar gives a milder caramel flavor, while dark brown sugar results in a deeper, molasses-rich taste.
Can I add mix-ins like chocolate chips or marshmallows?
Absolutely! While not traditional, folding in mini chocolate chips, toffee bits, or marshmallows can add texture and variety to your fudge.
