*Speculoos is a European cookie butter. It has a light gingerbread flavor.
I had a crazy idea to make a winter cocktail using the buttery cookie flavored spread, speculoos. Aviation gin partnered well because it has a light cardamom flavor that goes great with the gingerbread notes in the cookie butter. Although it's not chocolate chip, the combination of "aviation" and cookies reminded me of the old days of fresh baked, inflight snacks on Midwest Airlines
