Opinions?

Cookies made with butter always taste better than those made with trans-fats. The flavor is incomparable. Also, that frosting doesn't look homemade, so probably is too sweet and also loaded with trans-fats. Honestly, cookie baking isn't hard. Priority number one is quality ingredients, then control your other variables.

As for more filling.... I could easily eat all of those (would feel sick afterwards but still worth it)
