My five year old really can make them all by herself (aside from taking them in and out of the oven, of course) and surprisingly enough they are quite good cookies!
Mix all ingredients together and drop one inch spoonfuls onto a cookie tray (15-18 cookies).
Dip a fork in sugar and press down on the cookie dough to flatten and then repeat on the other side so you have intersecting fork marks. Repeat for each cookie.
Bake for 10-15 minutes. I find I prefer mine slightly under done.
