Preheat oven to 350°F (175°C) and grease an 8x8 inch square baking pan.
In a large mixing bowl, whisk together the creamy peanut butter, honey, egg, and vanilla extract until smooth and well combined.
Stir in the rolled oats, baking soda, and salt until the oats are thoroughly coated.
Gently fold in the semi-sweet chocolate chips using a spatula.
Transfer the mixture to the prepared baking pan and press down firmly and evenly into the corners.
Bake for 20 to 25 minutes or until the edges are golden brown and the center is set.
Remove from the oven and allow the bars to cool completely in the pan before slicing into 12 rectangular bars.
