You could do snickerdoodle hot chocolate! (Something we actually had years ago, not a secret menu item) It’s just a white hot chocolate with cinnamon dolce syrup (I think half of each?) and (maybe) cinnamon dolce topping

We come up with different ones monthly :)
For October it was an iced matcha w/ oat milk, mocha drizzle topped with cookie crumble called the Graveyard Smash
For September it was the Apple of my Eye - shaken espresso with apple brown sugar, topped with spiced apple drizzle in sweet cream foam. Those are just a couple we've had!
