I wanted to make a Stevia-sweetened chocolate milk so I tried mixing some unsweetened cocoa powder with the milk and stevia, but I found that the cocoa powder doesn't mix with the milk at all. It tends to float on top, and even with a lot of stirring and mixing back and forth between two glasses it was a lumpy mess.
Any techniques or natural additives I can use to help the powder dissolve more like Nestle Quick and the like?
