Ingredients You’ll Need
Believe it or not, this Penuche Recipe (Brown Sugar Fudge) Recipe calls for simple, pantry-friendly ingredients that come together to create a spectacularly soft and buttery fudge. Each one plays a crucial role, from sweetness and creaminess to texture and flavor depth.
- 3/4 cup butter (1 and 1/2 sticks): Adds richness and smoothness that makes the fudge melt in your mouth.
- 2/3 cup evaporated milk: Provides creaminess without watering down the flavor.
- 2 tablespoons light corn syrup: Helps prevent crystallization for a perfectly smooth fudge.
- 2 & 1/2 cups brown sugar: The star ingredient that gives the fudge its iconic caramelized taste and beautiful color.
- 12 ounces white chocolate bars (high quality): Melts into the fudge to create a creamy, sweet base—using bars over chips ensures a better texture.
- 1 (7-ounce) jar marshmallow creme (fluff): Adds lightness and a soft chewiness, elevating the fudge’s texture.
- 1 teaspoon vanilla: Enhances all the flavors with a warm aromatic note.
- 1/2 teaspoon kosher salt: Balances the sweetness and intensifies all the other flavors.
How to Make Penuche Recipe (Brown Sugar Fudge) Recipe
Step 1: Prepare Your Pan
Start by lining an 8 or 9 inch square pan with aluminum foil or parchment paper. If you’re using foil, coat it lightly with nonstick spray. This step is essential because it will make lifting the fudge out a breeze once it’s set, saving you from any sticky situations!
Step 2: Prep Ingredients for Quick Use
Get everything ready before you start cooking. Chop your white chocolate into small chunks to help it melt faster and more evenly. Open the marshmallow creme, peel away all foil seals, and keep it handy—microwaving it briefly is optional but it helps to scoop later. Set out your vanilla and kosher salt so you can add them right on cue.
Step 3: Melt the Butter Carefully
In a heavy 3-quart saucepan, melt the butter over medium-high heat. Don’t just let it sit—while it melts, spread some butter up the sides of the pan with a spoon or knife. This nifty trick stops sugar crystals from forming on the edges and ruining your fudge’s perfect consistency.
Step 4: Combine Milk and Corn Syrup
Add evaporated milk and light corn syrup to your melted butter. These ingredients help keep the fudge creamy and prevent it from crystallizing as it cooks, creating that signature smooth texture.
Step 5: Add Brown Sugar Carefully
Pour the brown sugar into the center of the pan, taking care not to let it touch the sides. This helps avoid crystallization issues and ensures your fudge cooks evenly.
Step 6: Stir Till Butter is Fully Incorporated
Use a wooden spoon to gently stir, slowly melting the butter into the brown sugar mixture until everything blends perfectly together. This sets the stage for the rich caramel base of your fudge.
Step 7: Bring to a Rolling Boil
Heat the mix to a full rolling boil over medium-high heat, stirring constantly with your wooden spoon. Once bubbling from the center, lower the heat to medium and keep boiling for exactly 5 minutes while stirring non-stop. This step is critical for the fudge to set up just right. If you have a candy thermometer, look for about 236 degrees Fahrenheit.
Step 8: Melt in White Chocolate
As soon as the timer goes off, remove the pan from the heat and add your chopped white chocolate. Stir vigorously and quickly until it melts and the mixture becomes silky smooth with no lumps. Don’t stop stirring or the fudge will start to harden too soon!
Step 9: Add Marshmallow Creme
Microwave the marshmallow creme in its jar for about 20 seconds until it rises a bit—this hack makes scooping so much easier. Stir all the marshmallow creme into your fudge immediately, blending it thoroughly while the fudge is still fluid and warm.
Step 10: Flavor with Vanilla and Salt and Beat
Drop in vanilla and kosher salt. Then, beat the fudge well with your spoon, scraping bottom and sides until everything is combined into a creamy, light golden blend without any streaks.
Step 11: Optional Nut Add-in
If nuts are your thing, toss in around 2/3 to 3/4 cup chopped toasted pecans now to add a crunchy, toasty contrast to the soft fudge. This step is totally optional but highly recommended if you love a little texture.
Step 12: Pour and Cool
Pour your luscious fudge into the lined pan immediately, spreading it evenly. Allow it to cool at room temperature for 3 to 5 hours. After about 30 minutes, cover it with plastic wrap to keep it moist. You can refrigerate to speed things up but let it come back to room temperature before slicing.
Step 13: Slice and Store
Once set, lift the fudge out using the foil or parchment edges. Cut into even squares with a sharp knife. Store on the counter covered, and enjoy within 3 to 5 days before it dries out.
How to Serve Penuche Recipe (Brown Sugar Fudge) Recipe

Garnishes
Sprinkle a pinch of flaky sea salt on top of your fudge squares for a sophisticated salty-sweet kick. Alternatively, finely chopped toasted nuts add inviting texture and a nutty aroma, making each bite feel extra special and indulgent.
Side Dishes
Serve your penuche fudge alongside a steaming cup of coffee or chai tea to balance its sweetness perfectly. It also makes a wonderful addition to dessert platters paired with fresh berries or shortbread cookies, enhancing your host game effortlessly.
Creative Ways to Present
Wrap individual fudge squares in parchment paper ribbons or place them in festive boxes for gifting during holidays or celebrations. For parties, try stacking bite-size penuche pieces in pretty glass jars or arrange them beautifully on a tiered dessert tray for eye-catching appeal.
Make Ahead and Storage
Storing Leftovers
Your leftover fudge will stay delicious on the counter for up to 5 days if covered tightly to prevent drying out. Keep it sealed in an airtight container or wrapped well in plastic wrap to maintain that perfect soft texture you fell in love with.
Freezing
Yes, you can absolutely freeze this fudge! For best results, slice before freezing and store in sealed containers or freezer bags. When you want a sweet indulgence, just let the fudge thaw at room temperature for a few hours—convenient and wonderful for holidays or unexpected guests.
Reheating
Fudge isn’t usually reheated like other desserts, but if you want softer pieces after refrigeration or freezing, simply leave them on the counter to come back to room temperature naturally. Avoid microwaving, which can alter texture.
FAQs
Can I substitute white chocolate chips for white chocolate bars?
White chocolate bars are strongly recommended because they melt more evenly and give a creamier texture. Chips often have stabilizers that prevent smooth melting, which can affect the fudge’s final consistency.
What is the purpose of corn syrup in this recipe?
Corn syrup helps prevent sugar crystals from forming during boiling, ensuring your fudge stays smooth and creamy rather than grainy or gritty.
Can I add nuts to this Penuche Recipe (Brown Sugar Fudge) Recipe?
Definitely! Toasted pecans or walnuts complement the flavor and add a pleasant crunch. Add them at the end right before pouring the fudge into the pan.
How do I know when the fudge has boiled long enough?
The fudge should be at a full rolling boil for 5 minutes, bubbling vigorously from the center and not just the edges. A candy thermometer reading about 236°F is the perfect indicator.
Why does the fudge sometimes get grainy?
Graininess usually occurs if sugar crystals form during cooking. Rubbing melted butter on the pan sides and being careful to avoid sugar sticking to the edges help prevent this. Stirring constantly and boiling at the right temperature also play important roles.
Final Thoughts
This Penuche Recipe (Brown Sugar Fudge) Recipe truly captures the essence of comfort and sweetness in every bite. It’s the kind of treat that feels simple but tastes spectacular—perfect for sharing, gifting, or sneaking a stolen piece when no one’s looking.
