Whole grain finger millet and sorghum successively replaced commercial soft-type wheat flour in the formulation of multigrain cookies (MGC) at 10-30% levels each. MGC were supplemented with fructoligosaccharide (FOS) at levels of 40%, 60%, and 80% sugar replacement basis. The quality attributes of cookies were evaluated in terms of spread ratio, hardness and nutritional characteristics. The spread ratio of control cookies (CC) was 4.400 and that of MGC with FOS ranged between 4.769 and 7.100. The initial hardness of CC was 70.0 ± 1.6 N and that of MGC with FOS ranged from 69.7 ± 0.7 N to 48.0 ± 1.2 N. MGC with FOS were significantly (p < 0.05) less hard than CC. Sensory data indicated moderate acceptability (OAA score = 7.3 ± 0.5) of MGC with FOS at 60% sugar replacement level, 20% finger millet and 30% sorghum. Total fibre including FOS (per 100 g) was estimated to be 17.4 g and 1.3 g for MGC with FOS and CC respectively. Caloric content of MGC with FOS was 11.7% lower than the CC. Acceptable cookies could be prepared with 50% whole-MG incorporation and up to 60% sugar replacement.
