Can I use different types of chocolate chips in peanut butter chocolate chip cookie bars?

Cornstarch is used to create a softer, more tender texture in the cookie bars. It helps prevent them from becoming too dense or hard, contributing to a light, chewy bite that complements the richness of the peanut butter and chocolate.
