Those waffles were lighter than I ever tasted before. I never tried malted milk powder when mixing batter for waffles. Do you know what malted milk powder adds to the taste or texture of waffles?
Well to me, its the taste of malt, which I love! Essentially the same flavor as the inside of a malted milk ball, or the malt powder that is used when brewing beer. I even love the taste of roasted, malted barley grain, which is where the malt powder comes from (after you make a brew of it and then evaporate the water so that only the extracted malt is left).
I think the Carnation version has milk powder added to it which makes it easier for most consumers to use.
