This is a really simple recipe. I actually found it scrawled in a baker friend's journal, so it's light on details, but it's easy and really delicious. It's based on a low carb recipe for atkins/diabetics that uses splenda, but I've only ever made it with sugar.
1 1/4c Almond Flour
1c Sugar (use Splenda if making low carb/sugarfree version)
1/4c Butter (softened)
1 lg egg
1 tsp vanilla
pre-heat oven to 350, and grease a baking sheet
Combine flour and sugar.
Blend in butter, egg, and vanilla (use an electric mixer)
Form dough into walnut-sized balls and place onto cookie sheet.
Bake for 5 minutes. Press down lightly with fork, then continue to bake for another 15 minutes. (Watch these like a hawk; they can burn easily, but they don't brown until they are slightly overdone. They're good even if overdone, though... they just turn a little crispy.)
