Line a 9x9-inch baking pan with parchment paper. Leave some paper hanging over the edges to use when lifting the fudge from the pan.
Place white bark in a microwave-safe bowl. Cook in 30-second intervals, stirring between each,
until the bark melts completely.
To the same bowl, add sweetened condensed milk and vanilla extract; stir to combine. Add in two-thirds of the crushed candy canes, and stir again to combine.
Pour mixture into the prepared pan. Sprinkle remaining candy canes evenly over the top.
Transfer pan to the fridge for 3 hours, or until fudge is set and can be cut.
Notes
If desired, substitute regular chocolate melting wafers for white.
1/4 cup crushed peppermint candies is roughly 5 standard size candy canes or 11 Starlight mints.
