If using whole nuts, grind them with a little bit of the flour from the recipe. Don't add more flour. This will help them from becoming nut butter. Trust me on this one. I have made nut butters way too often before using this trick. You can also do this with a little of the powdered sugar in place of the flour, I find that not every recipe that needs ground nuts calls for powdered sugar so I stick with using flour
Cornstarch is your friend. Don't skip this step. It's important for tender, soft cookies
Chill the dough before using. Then let thaw slightly so its easy to scoop out the dough to roll. You can make these right away after making the dough, but there is a chance they will spread a little more even with the cornstarch. I am all about chilling cookie doughs before baking.
Instead of using a scoop for these, I weight out the dough then roll. I use ½ oz per cookie. A scant tablespoon size. You can make them a little bigger, but I wouldn't go any smaller
Since these cookies don't spread you can bake a lot on one cookie sheet at once. I use parchment paper for these cookies.
Bake at 350 Deg F ( 177 C) for 10-15 min. I give a 5 min variation because some ovens run hot. Like mine does. I really need to get it adjusted. But. You don't want to overbake, just bake until the bottom edges start to brown.
