Creating Gingerbread Holiday Fudge is straightforward if you follow these simple steps:

1. Prepare the Pan: Line an 8-inch square baking dish with parchment paper, leaving some overhang for easy removal.
2. Combine Ingredients: In a medium saucepan, combine the granulated sugar, cocoa powder, butter, and sweetened condensed milk.
3. Heat Mixture: Place the saucepan over medium heat and stir continuously until the butter melts and the mixture is smooth.
4. Add Spices: Stir in the ground ginger, ground cinnamon, ground nutmeg, and salt. Mix until well combined.
5. Incorporate Vanilla: Remove the saucepan from heat and add the vanilla extract. Stir in the chopped nuts and white chocolate chips if using.
6. Pour Mixture: Pour the fudge mixture into the prepared baking dish and spread it evenly using a spatula.
7. Cool: Allow the fudge to cool at room temperature for about 45 minutes. For quicker cooling, you can refrigerate it for 20-30 minutes.
8. Cut Fudge: Once the fudge has set, lift it out of the dish using the overhanging parchment paper. Cut into squares or rectangles.
9. Store: Store the fudge in an airtight container at room temperature or refrigerate for longer shelf life.
