Improved high fiber shredded whole wheat cereal biscuits and their methods of preparation are provided. The methods include adding finely milled bran to tempered cooked whole wheat berries to form a blend. Masa (corn) bran is preferred. The methods include thereafter shredding the bran fiber fortified cooked whole wheat berries to form shredded mats and then forming the shredded mats into desired shaped and sized finished breakfast cereal pieces such as bite sized biscuits or nuggets. By adding the finely milled bran immediately prior to shredding, high levels of fiber fortification can be obtained while avoiding minimizing bran-speckled finished products.
