PB&J Thumbprint Cookies

"Okay, okay you caught me. They're not actually thumbprint cookies. I have a weird thing about sticking my thumb into cookie dough. I just can't. It makes ZERO sense because I'm totally rolling the cookie dough into balls with my hands, but that last step of poking it with my thumb? Not going to happen. Go ahead, judge my weirdness. I totally am. If you want to use your thumb for these, by all means do, but I used the back of a wooden spoon and it worked just fine. No thumbing necessary. (I feel weird even typing that)."
