Can 8 oz of sour cream substitute with 8 oz cream cheese in cookies?

Yes, you can substitute 8 oz of sour cream with 8 oz of cream cheese in cookies, but it may alter the flavor and texture slightly. Cream cheese is thicker and richer than sour cream, so your cookies may be denser and have a less tangy taste. To maintain moisture, consider adding a bit of liquid, like milk, if needed. Adjusting sugar levels may also be necessary, as cream cheese can be sweeter than sour cream.
