USDA’s Agricultural Research Service reports that white layer cakes can be made healthier by replacing some of the flour with finely ground corn bran without significantly undermining many of the qualities of this favorite treat.
Experiments done by USDA food technologist Mukti Singh determined that purified, finely ground corn bran can be used as a substitute for up to 20 percent of the flour called for in the American Association of Cereal Chemists’ “gold standard” test recipe for white cake.
The experiments found that using 20 percent corn bran fiber had no significant impact on qualities such as color or springiness and volunteer taste-tasters who sampled cake made with that amount of the fiber rated it as “acceptable” – which is good.
One slice of an 8-inch, 6-slice, two-layer white cake made with 20 percent corn bran fiber would provide about 5 grams of fiber, compared to about 1 gram from a conventional white layer cake. The USDA researcher say the corn bran recipe can be added to cakes that are prepared at commercial bakeries or to the boxed mixes sold for home bakers.
