Fannie May Fudge Recipe: Decadent Chocolate Indulgence

This recipe captures the legendary richness of that famous chocolate shop’s creation. The secret lies in precise temperatures and high-quality ingredients.

You’ll achieve smooth, melt-in-your-mouth texture with just 15 minutes of active work. The result is a decadent treat that rivals the original.

Ingredients for Fannie May Fudge

Decadent chocolate and a handful of pantry staples create this legendary confection with ease.

The cocoa powder is non-negotiable here. Hershey’s Special Dark or Ghirardelli deliver that deep, complex chocolate flavor this recipe demands. For the chocolate chips, Guittard or Callebaut are worth the splurge—cheap chips have waxy stabilizers that affect texture. Whole milk is essential; the fat content ensures that signature melt-in-your-mouth quality. Organic Valley or local dairy brands work beautifully.

No marshmallow creme? Homemade marshmallow fluff (egg whites, sugar, corn syrup) gets you close. Dairy-free? Swap whole milk for full-fat coconut milk and use vegan chocolate. Want nut-free? Skip the walnuts or use toasted pecans instead. The vanilla matters—imitation vanillas have a harsh aftertaste that cuts through the richness. Always use pure extract.

Fudge keeps beautifully at room temperature in an airtight container for 2 weeks. For longer storage, refrigerate for up to 1 month or freeze for 3 months. Let it come to room temperature before serving—the flavors deepen as it warms slightly.

Step-by-Step Instructions for Fannie May Fudge

Master the art of smooth, velvety fudge with these proven techniques and precise timing.

Step 1: Combine Sugar, Cocoa, and Dairy

In a heavy-bottomed saucepan, combine the 3 cups Granulated Sugar, 0.75 cup Unsweetened Cocoa Powder, 1 cup Whole Milk, and 0.5 cup Unsalted Butter cut into pieces. The heavy base prevents scorching during the long cooking process.

Place the saucepan over medium heat and stir constantly with a wooden spoon until the butter fully melts and the sugar dissolves completely. This is critical—undissolved sugar crystals can cause graininess in your final product. Continue stirring as the mixture begins to bubble.

Step 2: Reach the Soft-Ball Stage

Once the mixture reaches a full, rolling boil, stop stirring and allow it to cook undisturbed. Insert a candy thermometer and cook until the temperature reaches 234-238°F (soft-ball stage). This typically takes 15-20 minutes.

Watch for visual cues: the mixture will thicken slightly and develop a glossy sheen. If you don’t have a thermometer, test by dropping a small amount into ice water—it should form a soft ball that flattens when removed. Avoid the temptation to stir during this phase, as it can cause sugar crystallization.

Step 3: Incorporate Chocolate and Marshmallow

Remove the saucepan from heat and immediately add the 2 cups Semi-Sweet Chocolate Chips and 1 jar Marshmallow Creme. Stir vigorously until both are completely melted and the mixture is smooth. The residual heat will melt the chocolate without scorching.

Add the 1 tsp Vanilla Extract and 0.25 tsp Salt, stirring to distribute evenly. The salt enhances the chocolate flavor, while the vanilla adds depth. At this point, the mixture should be thick, glossy, and slightly cooler.

Step 4: Add Cream and Nuts for Texture

Stir in the 0.5 cup Heavy Cream until fully incorporated. This adds richness and ensures an ultra-smooth texture. Then fold in the 1 cup Chopped Walnuts (if using), reserving a small handful for topping if desired. Toasted walnuts provide a subtle crunch.

The fudge will begin to thicken as it cools. Work quickly but carefully to ensure even distribution of the walnuts. The mixture should now be thick enough to hold its shape when spooned.

Step 5: Set and Slice

Pour the fudge into a greased 8×8-inch or 9×9-inch pan, spreading it evenly with a spatula. Let it cool at room temperature for 2-3 hours, or refrigerate for 1 hour to accelerate the process. The surface should appear matte and firm to the touch when ready.

Once fully set, cut into 1-inch squares using a sharp knife. For clean cuts, warm the knife under hot water between slices. Store in an airtight container at room temperature for up to 2 weeks.

Make-Ahead Tips for This Dish

Prep Ahead Strategy

Measure all your dry ingredients the night before—3 cups sugar, ¾ cup cocoa powder, and ¼ tsp salt—and store them in a sealed container. This saves 5 minutes on cooking day and prevents last-minute scrambling. 💡

Pre-Toast Nuts

Toast the 1 cup walnuts in a 350°F oven for 8-10 minutes up to 2 days ahead. Let them cool completely before storing in an airtight container. This preserves their crunch and deep, nutty flavor.

Butter and Cream Prep

Cut your ½ cup butter into tablespoon-sized pieces and measure the ½ cup heavy cream in advance. Keep both refrigerated until ready to use. Cold butter incorporates more smoothly into the hot sugar mixture.

Pan Preparation

Line your 8×8-inch or 9×9-inch pan with parchment paper and grease it lightly with butter or nonstick spray. Do this the day before to ensure it’s ready when your fudge mixture is done cooking.

Marshmallow Creme Hack

If your 7 oz jar marshmallow creme is stubborn to scoop, microwave it for 10-15 seconds to soften. Measure it out and cover tightly—it’ll keep for 1 week at room temperature.

Timing the Cook

Since the entire process takes 15 minutes of active work, clear your schedule and have all ingredients prepped. The soft-ball stage (234-238°F) requires your full attention to avoid overcooking. ⏰
