Prepare the Chocolates

1. Melt the Dark Chocolate: In a microwave-safe bowl, melt the dark chocolate in 20-30 second intervals, stirring in between, until smooth and fully melted. Be careful not to overheat.
2. Melt the White Chocolate: Repeat the process with the white chocolate in a separate bowl.

Assemble the Bark

1. Spread the Dark Chocolate: Line a baking sheet with parchment paper. Pour the melted dark chocolate onto the parchment paper and spread it out evenly with a spatula. Let it sit for a few minutes to firm up slightly.
2. Add the White Chocolate: Once the dark chocolate has firmed up a bit but is still soft, drizzle the melted white chocolate over the top. Use a spatula to spread it out evenly, creating a marbled effect.
3. Top with Peppermint: Sprinkle the crushed peppermint candies over the white chocolate layer. Gently press down to ensure they stick.

Let the Bark Set

1. Cool and Set: Allow the bark to cool completely at room temperature for 15-20 minutes or refrigerate it for 10 minutes to speed up the setting process.
2. Break into Pieces: Once the bark is fully set, break it into large chunks with your hands or use a knife.
