Background: The study aimed to prepare cookies with high-quality ingredients which are a rich source of nutrition and have a good shelf life. The study proposed a healthy composition of cookies by incorporating antioxidant-rich green tea while replacing usual principal ingredients like all-purpose flour with cereals like Pearl Millet (Bajra) and oats while substituting unhealthy refined sugar with healthy powdered jaggery. The study thus evaluated the health benefits of green tea cookies based on their nutritional value and sensory analysis. Method and Materials: Cookies composed of five different compositions with varying concentrations of green tea, pearl millets, oats, jaggery, and other ingredients were prepared. Their physicochemical studies like change in width, density, thickness, volume, spread ratio, baking weight loss, fat, and ash contents were evaluated using standard protocols. Total flavonoid content, total phenolic content, and antioxidant activities of all cookies were determined. The sensory analysis was performed for all the five samples of cookies by Preference Tests-9 point hedonic rating. Results: There was a significant increase in TPC, TFC, and antioxidant activity. The sensory profile showed likeliness for these cookies. Conclusion: It can be inferred from the study that substituting pearl millet, oats, and jaggery with the normal ingredients enhanced the nutritional value and the likeliness of the cookies. Further incorporating green tea extract improved the quality of cookies and thus these cookies could be the promising source of healthy antioxidants.
