Ingredients You’ll Need
Gathering the right ingredients is the first joyful step toward making your Mackinac Fudge Recipe come to life. Each component plays an essential role, creating that signature creamy texture and deep chocolate flavor, with just the right hint of sweetness and richness.
- 2 teaspoons plus 1 cup butter: This balances richness and creates a silky smooth fudge base.
- 4 cups sugar: The key sweetener, providing that classic fudge structure and sweetness.

- 25 large marshmallows: Melted into the mix, these add gentle fluffiness and a tender texture.
- 1 package (11-1/2 ounces) milk chocolate chips: Contributes velvety chocolate smoothness and a mild sweetness.
- 2 cups semisweet chocolate chips: Bring a richer, slightly deeper chocolate flavor to balance the milk chocolate.
- 2 ounces unsweetened chocolate, chopped: Offers intense chocolate depth and cuts the sweetness for complexity.
- 1 teaspoon vanilla extract: Lifts and enhances all the chocolate and creamy notes with aromatic warmth.
- Decorating icing and sprinkles, optional: Perfect to add a personal touch or festive flair on top.
How to Make Mackinac Fudge Recipe
Step 1: Prepare the Pan
Start by lining a 13×9-inch pan with foil and greasing it generously with 2 teaspoons of butter. This step is crucial for easy removal of your fudge after it sets—and trust me, clean edges make all the difference when serving. Taking this little prep time upfront means less mess and more flawless fudge later!
Step 2: Make the Base
In a large, heavy saucepan, combine the sugar, milk, and the remaining 1 cup of butter, then bring this mixture to a rapid boil over medium heat, stirring constantly. This ensures all your sugar dissolves perfectly and avoids any graininess in the fudge. Once boiling, let it cook without stirring for exactly two minutes—this precise timing is key for the proper fudge consistency.
Step 3: Add the Marshmallows and Chocolate
Remove the pan from heat and immediately stir in the marshmallows until they melt smoothly. Then add all your chocolate chips and the chopped unsweetened chocolate, mixing until everything has melted together into one glossy, heavenly chocolate blend. Finish by stirring in the vanilla extract. This blend is the heart and soul of your Mackinac Fudge Recipe—rich, creamy, and perfectly balanced.
Step 4: Let the Fudge Set
Pour the warm fudge mixture straight into your prepared pan, then spread it evenly with a spatula. Allow it to cool for about one hour until it firms up enough to be scored. Scoring it into 1-inch squares now ensures neat portions once fully chilled.
Step 5: Cut the Fudge
Wrap the fudge-covered pan and refrigerate for about three hours or until completely firm. When ready, lift the fudge out of the pan using the foil edges. Remove the foil and cut into squares using a sharp knife warmed under hot water and dried—this little trick prevents crumbling and keeps your fudge looking professional and delicious. If desired, decorate with icing and sprinkles for an extra-special touch.
How to Serve Mackinac Fudge Recipe

Garnishes
A simple dusting of powdered sugar or a drizzle of melted white chocolate can elevate your Mackinac Fudge Recipe into an elegant treat. Sprinkles or crushed nuts add a playful crunch and make your fudge look as good as it tastes.
Side Dishes
Serve your fudge alongside a cup of freshly brewed coffee or a rich glass of cold milk. These classic pairings not only balance the fudge’s sweetness but highlight the complex chocolate flavors that make this recipe a true standout.
Creative Ways to Present
Try stacking fudge squares in a decorative jar tied with a ribbon for a lovely gift. Alternatively, arrange the pieces on a festive platter with seasonal accents like holly or cinnamon sticks to transform this homemade classic into a centerpiece conversation starter.
Make Ahead and Storage
Storing Leftovers
Once your Mackinac Fudge Recipe is fully chilled and cut, you can store leftovers in an airtight container at room temperature for up to a week. Keep the container in a cool spot to maintain that perfect texture—the fudge will stay creamy and fresh.
Freezing
If you want to enjoy your fudge later or prepare it ahead for a special occasion, freezing is a fantastic option. Wrap individual pieces tightly in plastic wrap and store them in a freezer-safe container for up to 3 months. Just thaw at room temperature before serving for the best experience.
Reheating
Fudge is usually enjoyed chilled or at room temperature, but if you prefer a soft, gooier texture, you can microwave individual squares for about 5-7 seconds. Be careful not to overheat, or it may become too melty. This little warm-up can bring out that freshly-made feeling.
FAQs
Can I use a different type of milk for this fudge?
Yes! While this Mackinac Fudge Recipe calls for 2% milk, you can substitute whole milk or even cream for a richer fudge. Just keep in mind that lower fat milks might affect the texture slightly, making it a bit less creamy.
Is it necessary to use all three types of chocolate?
Using milk chocolate, semisweet chocolate, and unsweetened chocolate together gives the fudge its unique depth and balance. However, if you prefer, you can adjust the proportions or omit unsweetened chocolate, but the flavor profile will be sweeter and less complex.
Why do I need to let the fudge cool before scoring it?
Cooling the fudge before scoring allows it to set but remain soft enough to cut cleanly. Cutting too soon can cause sticky, messy edges, while waiting too long might make it harder and prone to cracking.
Can I add nuts or other mix-ins to this recipe?
Absolutely! Chopped walnuts, pecans, or even dried fruit can be stirred in after the chocolate has melted. Just fold them gently to maintain the fudge’s smooth texture.
What is the best way to prevent grainy fudge?
Stirring constantly until boiling and then cooking without stirring for exactly two minutes helps dissolve the sugar completely and fosters a smooth finish. Also, avoid any sugar crystals on the pot’s sides by rinsing them down with a wet pastry brush if necessary.
