A method for forming a grain-based cereal paste that includes preparing a mixture of the paste and water at a target first cereal-to-water weight ratio, boiling the mixture for a target boiling duration of time, cooling the mixture to a prescribed temperature for a target cooling duration of time, adding enzymes to the mixture, the amount of enzymes calculated based on a dry weight of the paste in the mixture, maintaining the mixture with added enzymes for a specified duration of time at a specified temperature, preparing a dehydrated mixture by removing water from the mixture to result in a prescribed moisture content for the dehydrated mixture, admixing a plant based oil to the dehydrated mixture at a prescribed oil-to-mixture weight ratio, and milling the dehydrated mixture containing the admixed plant based oil to prepare a paste with a particle size in a range of 1 to 120 microns.
