Prep the pan: Line a rimmed baking sheet with parchment paper. For thicker bark, use a smaller sheet or an 8x12-inch pan.
Crush the candy canes: Place unwrapped candy canes in a plastic bag.
Tap gently with a rolling pin until you have a mix of smaller pieces and peppermint dust.
Melt the chocolate: In a microwave-safe bowl, heat white chocolate in 20–30 second bursts, stirring between each, until smooth. Or use a double boiler over gently simmering water. If using, stir in a teaspoon of neutral oil or a bit of cocoa butter for shine.
Flavor it: Stir in peppermint extract and a pinch of sea salt.
Start with 1/2 teaspoon extract, then taste. Add a drop more if you want a stronger mint flavor.
Optional dark chocolate layer: Melt dark chocolate separately and spread into a thin, even layer on the parchment. Chill 5–7 minutes until just set but still slightly tacky.
This helps the white layer adhere.
Spread the white chocolate: Pour the white chocolate over the prepared pan (or over the tacky dark chocolate). Use a spatula to spread it to about 1/4 inch thickness.
Top with candy canes: Sprinkle the crushed candy canes evenly over the surface. Gently press them so they stick as the chocolate sets.
Chill to set: Refrigerate for 20–30 minutes, just until firm.
Don’t leave it for hours or it may sweat when brought back to room temperature.
Break into pieces: Peel the bark off the parchment and snap into irregular shards. Aim for palm-sized pieces for gifting.
Serve or store: Keep at cool room temperature in an airtight container, or refrigerate if your kitchen is warm.
