The easiest, richest, yummiest peanut butter cookies on the planet

 

1 cup peanut butter (or almond butter, sunbutter, cashew butter, soy butter, or my fave, mixed nut butter)
1 cup brown sugar (if you don't have brown, white will do. They will be less chewy and more crisp)
1 egg
1 tbs vanilla extract
Optional: Chocolate chips, nuts, candied nuts, chocolate squares, jelly, candied fruit

Mix all. If using chocolate squares, jelly or candied fruit, hold on to those.
Roll into small balls, the size of a shooter marble.
Place on a tray, one inch apart.
Smoosh with a fork if you like. If you are holding onto one of those other things, press them into the top of each cookie. If you are using jelly, press down with your thumb to make a pond and then fill it with jelly. Make sure your jelly pond doesn't leak, or you will have a big sugary, burnt mess where your cookies should be.
Bake for 8 minutes at 325.
Cookies will be very gooey. Let cool slightly on tray, then transfer to rack to cool completely. They are VERY rich. Make them little and pace yourself.
