Maybe it's the altitude, but these little suckers are kind of hard to roll into a ball without it collapsing.
These were good on their own, but I thought some peanut butter would really make them shine. So, I mixed about a 1/2 cup of creamy peanut butter with an electric mixer until it was fluffy. I loaded it into a zip-top bag and piped it onto every other cookie bottom to make sandwich cookies. Yum!
