Work dough ingredients together with a pastry blender or the tines of a large fork until completely blended.
Scoop the dough up by rounded tablespoons, or a bit more if you’d like larger cookies. Arrange on a parchment-lined baking sheet.
Flatten the dough lightly with your palm, then press down lightly with a regular-sized fork in two directions to make that cool criss-cross pattern that peanut butter cookies are known for.
Bake cookies for 10 minutes, or until the bottom of the cookies are golden brown.
Allow cookies to cool for a bit to firm up, then transfer to a plate or container. Store cookies covered at room temperature.
