Food companies are faced with an increased demand by health professionals and consumers for healthier food products. The need for flours that are free of gluten (such as millet, tapioca, potato, soy, flax, etc.) are becoming progressively more popular and are offering new sales potentials for food companies. It is against this background that the study was undertaken to produce millet based sponge cakes with the view of improving the sensory and nutritional values of the product. In addition to a control sample using only wheat flour, ten different cake formulations were prepared using varying wheat and millet flours ratios. Sensory analysis using forty untrained panel and proximate analyses were performed. The results revealed that significant differences in visual puffiness, appearance, texture/mouthfeel, moistness and smell acceptability were not observed among these products. Superimposition of the optimal areas having a score greater than 6.0 from each attribute was done to obtain an optimal formulation range. However, the sensory assessments of the products on the 9-point hedonic scale depicted that all products scores were more than 6 on the scale which is an indication that all sensory attributes were at least liked slightly in each case by the panel. Panel was able to correctly discriminate between the different samples in terms of the sensory attributes on the 9-point hedonic scale. However, the overall liking of the samples as perceived by the panel indicated that all products were acceptable with Sample E being the most preferred. Positive purchase intent was noticed among the panel hence offering new sales potential for the millet based cakes. There was improvement on the nutritional content (carbohydrate, fat and ash) of the formulations as the proximate analysis generally showed a mean increase of 2.08±0.36% for ash and 33.41±3.32% for fat against the control sample of 1.53% and 30.96% respectively. No significant change was observed in the protein content (7.43±0.92% against 7.44%). However, there was a decrease (71.41±5.38%) in carbohydrate content against control sample of 77.43%.
