A couple of things to know when baking: It's an exact science, so be exact with your ingredients and measurements. DO NOT USE IMITATION VANILLA. You deserve the real thing. Mexican vanilla is my personal favorite. It adds that certain je ne sais quoi that makes the cookies special. If you don't have time to jaunt down to Mexico for spices, it can usually be found at Fiesta grocery stores or specialty baking shops. Chill the dough overnight for best results. Resist the urge to eat too much raw cookie dough. It's good, but the baked cookies are much much better.
Please know that I didn't create all of these recipes, but I have mastered them. My favorites among those pictured below: Chocolate Peanut Butter Thumbprints. Though they're all ridiculously good. Enjoy!
