Prepare the Baking Sheet: Line a baking sheet with parchment paper, ensuring it covers the entire surface. This will prevent sticking and make cleanup easier.
Melt the Chocolate: In a microwave-safe bowl, break up the dark chocolate into small pieces. Heat in the microwave in 30-second intervals, stirring between each interval, until fully melted and smooth. Do not overheat.
Mix in Add-ins: Once melted, remove the bowl from the microwave. Stir in the mixed nuts and dried cranberries, ensuring they are well coated in chocolate.
Spread the Mixture: Pour the chocolate and nut mixture onto the prepared baking sheet. Use a spatula to spread it into an even layer, about ¼ inch thick.
Add Sea Salt: While the chocolate is still melted, sprinkle the flaky sea salt evenly over the top. Press gently to help it stick.
Set the Bark: Place the baking sheet in the refrigerator for about 1-2 hours, or until the chocolate has completely hardened.
Break Into Pieces: Once set, remove from the refrigerator. Break the bark into irregular pieces with your hands or a sharp knife for a rustic look.
Notes
Serve the bark on a decorative platter. For a festive touch, wrap pieces in cellophane and tie with a ribbon for gifting!
