Why is my batter more flavorful than my cookie?
I made an oatmeal cookie recipe that featured five spice powder. The raw batter tasted incredible - really rich and deeply flavorful. But once they were baked they tasted just like a lightly spiced oatmeal cookie.
Where did all that rich flavor go, and how can I keep it present in the end result?

Custard-filled buns topped with sanding sugar.
