Preheat oven to 350 degrees.

Combine peanut butter and sugars and until smooth (1-2 minutes on medium speed).

Add egg, vanilla, baking soda, and salt. Mix for about a minute.

If adding chocolate, fold into dough now. Chocolate is optional, really.

Using a tablespoon ice cream scoop, scoop and shape dough into balls, roll in sugar.

Place balls on parchment lined cookie sheet, approximately 11/2 inches apart.

Using a fork, flatten with a criss cross pattern, or simply flatten with the bottom of a glass.

Press one chocolate chunk or chip into the center of cookie after flattening the dough.

Bake for 8-9 minutes, don’t overbake!

Let them sit on the baking sheet for a few minutes before transferring to a cooling rack. Makes approximately 2 dozen cookies. Recipe can be doubled easily.
