How to prepare the mint for the cookie dough? I started chopping, but it doesn't say to do that!

Nice catch creamtea!

Thanks gals....I actually went straight off the recipe...Now that you mention the photos, you're right...it does look like they are whole...I am not sure how I feel about that!

The photos show whole mint leaves being added to the mixing bowl.

Hopefully TheRunawaySpoon weighs in, but I think your assumption was correct, I would chop it.
