Creamy and spicy together.
We have apple cinnamon but it’s so hard hitting I want something like cinnamon hot chocolate.
Also anything caramel is great.
I’m a huge fan of seasonal scents so watermelon jolly rancher type smells or strawberry shortcake in the summer is great
garden herb 
I recommend anything teakwood. Those are great
Anything Lavender, can't go wrong with Lavender.
