Prepare the Baking Sheet: Begin by lining a baking sheet with parchment paper, ensuring it covers the entire surface.
Melt the White Chocolate: In a microwave-safe bowl, add the white chocolate chips. Microwave them in 30-second intervals, stirring well in between each interval until melted.
Add Flavor: Once melted, stir in the peppermint extract thoroughly.
Fold in the Peppermint Candy: Gently add the crushed peppermint candies to the melted white chocolate mixture, reserving some for topping.
Spread on the Sheet: Transfer the mixture onto the lined baking sheet and spread it into an even layer, approximately 1/4 inch thick.
Drizzle Dark Chocolate (Optional): Melt dark chocolate and drizzle it over the white chocolate layer if desired.
Add Reserved Candy: Sprinkle the reserved crushed peppermint candies over the top and press them gently into the chocolate.
Chill and Set: Place the baking sheet into the refrigerator for about 2 hours until set.
Break into Pieces: Once solidified, remove from the baking sheet and break into desired sizes.
Garnish with Sea Salt: Sprinkle a pinch of sea salt over the chocolate pieces just before serving.
Notes
For an elegant presentation, serve on a decorative platter with whole peppermint candies or fresh mint.
