For an extra touch of elegance, drizzle additional melted sunflower seed butter over the bark before chilling. Feel free to experiment with different types of chocolate, such as milk chocolate or white chocolate. Add other toppings like dried cranberries, chopped nuts (if not avoiding nuts), or shredded coconut for added flavor and texture. Store the bark in an airtight container in the refrigerator for up to a week, or in the freezer for longer storage.
