    In recent years, health concerns have driven the food industry to develop products with improved nutritional profiles. Within this context, the baking industry has been propelled by the demand for baked goods with enhanced nutritional emphasis. Premixes, due to their practicality and versatility, have positioned themselves as an attractive alternative for the quick preparation of baked products. However, commercial options available on the market are designed for widespread consumption, lacking a nutritional focus. In the present work, three premix treatments were developed made with a mixture of national wheat, quinoa and amaranth flours with a fixed composition of the other components, where a sensory analysis was carried out on the different brownie treatments using a Complete Randomized Block Design to identify the best treatment. The treatment with greater acceptability has attractive sensory characteristics, with a texture comparable to the control sample, evidenced by values of 4.67 (N) for hardness, 0.21 mJ for adhesiveness and 0.34 for cohesiveness. Furthermore, the rheological analysis of the dough presented significant differences except for the retrogradation of starch with the blank, obtaining a time of 45.01 min with a torque of 0.84 Nm. From a nutritional point of view, the best formulated brownie exhibited an enriched profile, with a high content of 34.26, 27.8, 8.22, 3.73 percent of carbohydrates, fat, protein and dietary fiber.
