In a microwave safe bowl, combine white and chocolate chip morsels, sweetened condensed milk and butter.
Microwave for 2-3 minute increments and stir until mixture is smooth and creamy. Repeat as many times needed. For repeat trips to the microwave, heat in 1 minute increments as to not scorch the chocolate
Once fully melted and smooth, add vanilla and all spices and mix thoroughly.
Fill Gingerbread silicone mat or a foil lined, 9x9 pan. If using 9x9 sheet, now is the time to add any colored sprinkles or snowflakes if you wish. Refrigerate 2 hours or until set.
Carefully remove fudge from silicone mold or slice fudge into bite size pieces.
Setting time may vary. This will start to set quickly as it cools. It can also set at room temperature but will take longer than if refrigerated.
