Prep Times and Heat Intensities
Understanding the exact timing and stovetop heat levels is key to preventing grainy sugar crystals or burnt chocolate.
| Stage | Time Required | Stovetop / Activity Intensity |
| Preparation & Pan Lining | 5 minutes | None (Room Temperature) |
| Initial Boiling Setup | 3 minutes | Medium Heat (Stirring Constantly) |

Ingredients List
To create authentic Toll House Famous Fudge, use high-quality ingredients as listed:
-
Granulated Sugar: 1 ½ cups
-
NESTLÉ® CARNATION® Evaporated Milk: ⅔ cup (5 fl. oz. can)
-
Butter or Margarine: 2 tablespoons
-
Salt: ¼ teaspoon
-
Miniature Marshmallows: 2 cups
-
NESTLÉ® TOLL HOUSE® Semi-Sweet Chocolate Morsels: 1 ½ cups (approx. 9 ounces)
-
Vanilla Extract: 1 teaspoon
-
Chopped Pecans or Walnuts (Optional): ½ cup
Step-by-Step Cooking Instructions
Step 1: Pan Preparation
Line an 8-inch-square baking pan with aluminum foil or parchment paper, allowing the edges to overhang slightly. Lightly grease the foil with non-stick cooking spray or a drop of butter to ensure easy release. (Note: For thicker fudge squares, you can use a 9×5-inch loaf pan instead).
Step 2: Combine and Heat Base Ingredients
In a heavy-duty saucepan, combine the 1 ½ cups granulated sugar, ⅔ cup evaporated milk, 2 tablespoons butter, and ¼ teaspoon salt.
-
Intensity: Set your stovetop to Medium Heat.
-
Stir constantly using a heat-resistant spatula or wooden spoon to dissolve the sugar evenly and prevent scorching.
Step 3: Achieve Full Rolling Boil
Bring the mixture to a full rolling boil (a boil that cannot be stirred down).
-
Intensity: Maintain Medium Heat.
-
Time: Once the full boil is achieved, boil for 4 to 5 minutes, continuing to stir constantly so the milk solids do not burn on the bottom of the pan.
Step 4: Remove from Heat & Incorporate Chocolate
Immediately remove the saucepan from the heat source.
-
Intensity: Off Heat / Zero Stovetop Heat.
-
Quickly add the 2 cups of miniature marshmallows, 1 ½ cups chocolate morsels, 1 teaspoon vanilla extract, and optional chopped nuts.
Step 5: Vigorous Blending
Stir the mixture vigorously for 1 full minute or until the marshmallows and chocolate chips are completely melted and the batter forms a uniform, glossy emulsion.
Step 6: Pour and Set (The Last Stage of the Recipe)
Immediately pour the molten fudge into your prepared 8-inch baking pan, smoothing the top surface evenly with a spatula.
-
Setting Phase (Last of the Recipe): Place the pan into the refrigerator and chill for at least 2 hours (or 3 hours if using a 9×5 loaf pan) until completely firm.
-
Once fully set, lift the fudge out of the pan using the foil overhang handles. Peel off the foil and slice into 48 individual bite-sized squares using a sharp chef’s knife.
Pro Tips for Perfection
-
Use Heavy-Bottom Cookware: A saucepan with a thick bottom distributes heat evenly and prevents hot spots that burn evaporated milk.
-
Do Not Substitute Milk: Evaporated milk is essential for proper density and fat structure. Do not use sweetened condensed milk or regular fluid milk.
-
Clean Cutting: Dip your knife in warm water and wipe it dry between cuts to get smooth, clean edges on every fudge square.
Storage & Shelf Life
-
Room Temperature: Store in an airtight container between layers of wax paper for up to 1 week.
-
Refrigeration: Keeps fresh in an airtight container in the fridge for up to 2–3 weeks.
-
Freezing: Wrap individual pieces in plastic wrap, place them in a freezer bag, and freeze for up to 3 months. Thaw in the refrigerator overnight before serving.
