No. According to a search on the official website of Haagen-Dazs, the words "This coupon cannot be exchanged for cash or other goods, and is valid until September 30, 2012, will be invalid after expiration" is marked on the back of the Haagen-Dazs mooncake coupon. Therefore, Haagen-Dazs mooncake coupons can only be exchanged for Haagen-Dazs ice cream mooncakes, not ice cream.
