Dark Chocolate Peanut Butter Cups - 4 oz.

What percentage dark chocolate are these?

Does this order contain six separate packages, or one package containing 6 cups?

The ingredients list "cane sugar." If it's granulated cane sugar, this is not vegan due to the bone char. Anyone know?

This product lists powdered sugar as an ingredient. Powdered sugar sometimes contains cornstarch. I’d like to know, is this powdered sugar corn-free?
