Step 1: Prepare the Fudge Base

1. In a medium saucepan, combine the heavy cream, granulated sugar, and unsalted butter.
2. Heat the mixture over medium heat, stirring constantly until the butter melts and everything is combined.
3. Bring the mixture to a gentle boil and continue cooking for 4–5 minutes, stirring occasionally to prevent burning.

Step 2: Add the Chocolate and Marshmallow

1. Remove the saucepan from the heat.
2. Stir in the white chocolate chips and marshmallow cream. Mix vigorously until the chocolate melts completely, and the mixture is smooth and creamy.

Step 3: Flavor and Color

1. Add 3 teaspoons of orange extract and stir until the flavor is evenly distributed.
2. Gradually add 8–10 drops of orange food coloring, stirring as you go. Adjust the color to your liking—add more for a vibrant orange or less for a pastel hue.

Step 4: Pour and Set

1. Line an 8×8-inch baking pan with parchment paper, leaving some overhang for easy removal.
2. Pour the fudge mixture into the prepared pan and spread it evenly with a spatula.
3. Let the fudge cool at room temperature for 15–20 minutes before transferring it to the refrigerator.
4. Chill for 4–6 hours, or until the fudge is completely set.

Step 5: Slice and Serve

1. Once the fudge is firm, lift it out of the pan using the parchment paper overhang.
2. Place it on a cutting board and slice it into small squares or rectangles using a sharp knife.
3. Serve immediately, or store for later enjoyment.
