Step 1: Prepare the Pan and Cups
Nest two mini fluted paper or foil cups together for each fudge cup—this provides extra stability and a neater appearance. Place each double-layered cup securely into the wells of a mini muffin tin. This tin will hold the cups in perfect shape as the fudge sets. Have all your coloring and decorations ready.

Step 2: Melt the Fudge Base
In a medium, heavy-bottomed saucepan, combine the sweetened condensed milk, butter, and salt. Heat over medium-low heat, stirring constantly with a silicone spatula, until the butter is fully melted and the mixture is smooth and begins to steam slightly. Do not let it boil. Reduce the heat to low. Add all of the finely chopped white chocolate. Stir continuously until the chocolate is completely melted and the mixture is smooth, glossy, and uniform. This should take 5-7 minutes. Important: Keep the heat low to prevent the white chocolate from scorching or seizing.

Step 3: Flavor and Divide the Fudge
Once smooth, remove the saucepan from the heat. Stir in the peppermint extract and vanilla extract until fully incorporated. Immediately divide the fudge mixture evenly into three separate bowls. A kitchen scale is helpful here for precision, but aim for roughly equal portions.

Step 4: Color the Fudge Portions
Leave one portion plain white. To the second portion, add red gel food coloring, a drop or two at a time, stirring until you achieve a vibrant, festive red. To the third portion, add green gel food coloring until you reach a deep holly-green color. Gel coloring is preferred over liquid as it provides vibrant color without thinning the fudge.

Step 5: Layer and Swirl the Fudge into Cups
Working quickly before the fudge begins to set, spoon small amounts of each color into the prepared cups. You can do this randomly for a rustic look, or use a more precise method: transfer each colored fudge to a separate piping bag or small zip-top bag with a corner snipped off. Pipe small dollops of each color into each cup, layering them. Once all cups have a base of colored fudge, use a toothpick, wooden skewer, or a pin tool to gently swirl the colors together. Aim for just 2-3 swirls to create a beautiful marbled effect without blending them into a muddy brown.

Step 6: Decorate with Candy Canes and Sparkle
While the fudge surface is still soft and tacky, immediately sprinkle the top of each cup with the crushed candy cane pieces, pressing gently to adhere. Follow with a light sprinkle of edible glitter or sparkling sugar for a magical, frosty finish.

Step 7: Set and Serve
Allow the fudge cups to set at room temperature for 1 hour, then transfer the entire muffin tin to the refrigerator. Chill for at least 2-3 hours, or until completely firm. Once set, they can be stored in an airtight container in the refrigerator or a cool place. Serve directly from the cups. Let them sit at room temperature for 10-15 minutes before serving for the best creamy texture
