Preheat your oven to 350 degrees. Line a cookie sheet with a baking mat or parchment paper.
Mix the sugar and peanut butter together, then add baking soda and eggs.
Mix well, then stir in the chocolate chips. (I've also used a wooden spoon…no mixer… when I was in a hurry–and It worked great!)
Roll the dough into balls and place on the prepared baking sheet, then flatten them just a bit with your fingers. (Option: Roll cookie dough balls in granulated sugar before baking.)
Bake for 9-10 minutes, or until the edges are set. Let the cookies cool for a few minutes before removing from cookie sheet. If you want to make Peanut Butter Blossoms, press unwrapped mini Reese's PB cups into the center of each cookie as soon as they come out of the oven. Let cool completely.
