This came my way from AlexaK, so thank you!
It reminds me a lot of the Creamy Caramel Oolong from Tealish. The first sip was very much tea-ja-vu to me.
The oolong is a little nutty and just a touch toasty, and the caramel adds a small amount of butteriness and sweetness. It suffers from the same issues as the Tealish one, though. While the oolong pairs well with the flavors the caramel was offering, I wish the caramel aspect was louder. As it stands, this could almost be an unflavored oolong with caramel/burnt sugar notes and not a luscious buttery caramel flavored oolong.
