A baking mix-in for cookies or brownies refers to a variety of flavorful ingredients folded into batter before baking, such as chocolate chips, nuts, dried fruit, or candy pieces. These additions are typically stirred into a standard cookie or brownie dough, which is then baked until set. The concept is a staple in American home baking, popularized in the 20th century.
These mix-ins are generally high in carbohydrates and fat, with minimal protein, depending on the specific add-in chosen. A single cookie or brownie serving with a standard mix-in like chocolate chips typically ranges from 150 to 250 calories.
