New Game: What's your favorite single FLAVOR in a cookie?
1. Must be in a cookie, but you can argue for cookie adjacent
2. Must be ONE flavor, not a combination.
3. Not a kind of cookie, just a flavor.
Examples, chocolate chip is a kind of cookie, so that's out, but chocolate is okay, meaning chocolate in cookies, not necessarily a chocolate cookie, though that's included too. Oatmeal is probably out unless you're just wild for the flavor of oats. "Spice" is out, even if you buy a blend, but cinnamon is a good answer.
I was making Moravian ginger cookies and thinking about my very favorite cookie flavor component.
