Can I use margarine instead of butter? In order for the cookies to turn out ​well, butter must be used.

Does it matter what kind of milk I use? Nope! As you can see from the video/pictures, I decided to use ​almond milk, but it is up to your preference. 

When placing the cookies onto the pan, it is best to lightly cover your hands in shortening to reducing sticking. 

Does it matter what kind of chocolate I use? This is up to you as well. When receiving the recipe, I was told that milk chocolate would be best since the cookies themselves are not very sweet. However, as you can see from the video/pictures, I decided to use dark chocolate since I personally prefer it better.

If cookies are made 1-1 1/2 inches wide, you should yield about 5-6 dozen cookies.
