Actually, come to think of it, these were really bomb scones. But yeah, kind of lame cookies.
1 tsp vanilla extract
1 c all purpose flour1. Once the peeled chestnuts are fully cool, chop them coarsely on a cutting board. Measure 1/2 cup of chopped chestnuts, and dump them in the bowl of a food processor. Grind them until they are very well chopped, then add the softened butter, and pulse again until combined. Add 1/4 cup of your powdered sugar, vanilla extract, 1/4 tsp cinnamon, nutmeg, salt and flour and pulse until an even dough is formed.
In other news, the sun finally came out for a while when I was making these cookies, though both preceded and followed by thunder and lightning.
