Preheat the oven to 350°F/180°C. Line a baking sheet with parchment paper.
Combine the peanut butter, sugar, egg and baking soda in a medium-size bowl and use a very sturdy wooden spoon to beat the ingredients together until well combined.
Drop golf ball–size balls of dough, spaced evenly apart, onto the prepared baking sheet. Make a crisscross impression into the dough with a fork. Bake for 10 to 12 minutes or until cookies are still a bit soft in the center and just barely colored on the bottom. They firm up upon cooling. Do not overbake! Place pan on rack to cool.
Store the cookies in an airtight container at room temperature for up to 4 days.
Chocolate Chip Peanut Butter Cookies: Stir in ½ cup (85 g) miniature or standard size semisweet chocolate morsels (using dairy-free if desired) into the batter after it is all mixed. Form, bake, and cool as directed.
