This study investigated the quality characteristics of cookies made with chestnut inner peel powder and its potential as a food ingredient. Cookies were made with various levels (0, 10, 20, 30, 40%) of chestnut inner peel powder. Dough pieces were baked for 20 minutes at $180^{\circ}C$ in an electrically heated rotary oven for about 10 minutes, and all items were measured after cooling for 24 hours at normal temperature. Quality characteristics were measured by moisture content, leavening rate, loss rate, spread factor, color, texture profile analysis, and sensory evaluations. The moisture content of cookies was significantly affected by increasing chestnut inner peel powder (p<0.001). The spread factor as well as L-value and b-value of cookies significantly decreased with increasing chestnut inner peel powder content (p<0.001). However, hardness and redness (a-value) of cookies significantly increased with increasing chestnut inner peel powder content (p<0.001). The sensory score showed that cookies added with 20% chestnut inner peel powder had higher color, texture, and overall acceptability scores than other samples. As a result, quality of cookies added with 20% chestnut inner peel powder was the most suitable, and we suggest that chestnut inner peel is a good ingredient for increasing the consumer acceptability and functionality of cookies.
