Remember that foods that are ‘pumpkin spice’ flavored don’t contain any flavor of pumpkin. It’s just a mix of cinnamon, ginger, cloves, nutmeg and allspice.
That said, I don’t think that spice blend mixes well with dark or milk chocolate. It would be fine with white chocolate, which could then easily be colored orange and probably make an overall better product in both appearance and flavor.
