How to make cookies less sweet?

Hi just wanna ask po if paano mag adjust ng recipe para maging less sweet ung cookies. Ginagamit ko yung recipe from broma and i did the chocolate chip skillet recipe niya, and super sweet nung kinalabasan kaya ending d masyadong naubos ung ginawa ko huhu if magbawas kaya ako ng sugar sa recipe d naman po kaya maapektuhan yung appearance ng cookies??
