Blooming Chocolate A Thing?

Every morning I make a big mug of coffee. I use the pour over method because it takes a lot less room on my limited counter space. Love the smell of coffee but not so much the taste. Being lactose intolerant I use oat milk.  Trader's Joe chocolate oat milk was my go to but after they discontinued it, I had to make my own. Which is a healthier way to go.  I read that coco powder has to be activated with something warm to get the full flavor. I've been trying it so see if that method is true. I would like to think it's working as I think my coffee is a little more chocolatey tasting but it could be just wishful thinking.
