This is Emily from Back to the Cutting Board. I wanted to let you know there is a typo in the recipe that I fixed yesterday, but it looks like you copied it before that.
In Step 4, use 1/2 cup peanut butter (like it says in the ingredients list) instead of 1/4 cup peanut butter.
Sorry about the typo, I just didn't want anyone's cookies to come out dry.
