If you're old enough to remember soda jerks and malt shops, did you ever drink a "malted" as a kid? This was a milkshake with Malt powder sprinkled on top. The flavor was like finely smashed malted balls without the chocolate, but I think the "malt" itself consisted of malted barley, wheat flour and whole milk that was in powder form. I think there were ice cream sundaes made with vanilla ice cream, and drenched in chocolate syrup and malt powder, too.
Perhaps a throw-back to the days of Prohibition when malt companies had to develop legal uses for malt?
Does anybody know?
