Line a tray or plate with parchment paper and prepare all toppings before melting the chocolate. Organizing ingredients first helps you work quickly once the chocolate is smooth and ready to spread.
Melt the semi-sweet chocolate chips, dark chocolate chips, and coconut oil in short microwave intervals while stirring between each round. Careful melting prevents burning and creates a glossy finish.
Pour the melted chocolate onto the prepared tray and spread evenly into a rectangle about 1/4-inch thick. Keeping the layer consistent helps the bark break into clean pieces later.
Sprinkle chopped almonds, peanuts, crispy rice cereal, and pretzels evenly over the chocolate. Gently press toppings into the surface so they stay attached after chilling.
Add dried cranberries, mini marshmallows, white chocolate chips, and flaky sea salt across the top. This combination creates balanced sweet, salty, and crunchy flavor in every bite.
Refrigerate the bark until fully firm, then break into rustic pieces before serving or storing in an airtight container.
