Line an 8x8" square pan with aluminum foil and spray with non-stick spray
In a saucepan over low heat, place the white chocolate chips, butter, and condensed milk.
Stir constantly over low heat until the mixture melts completely.
When the mixture is melted, add the cinnamon, nutmeg, ginger, vanilla, salt, and sprinkles. Stir until combined
Pour the entire mixture in the prepared pan and leave it at room temperature to set. About 1-2 hours
When the fudge is solid, cut into 1 1/2" squares (you can cut them smaller or larger if you'd like)
If your fudge is too soft, simple place in the fridge for 10-15 minutes
