Preheat oven to 350°F (175°C).
Mix together peanut butter, sugar, baking soda and salt in a medium bowl until smooth. Beat in egg. Stir in MILK CHOCOLATE CHIPS.
Spoon heaping tablespoonfuls of dough 2 inches apart onto parchment paper-lined baking sheets.
Bake for 10 to 12 minutes or until lightly browned.
Let the cookies cool on the baking sheets until firm enough to handle, then use a spatula to transfer them to a wire rack for cooling.
