Line an 8-inch square baking pan with parchment paper, leaving some overhang on the sides for easy removal.

In a large mixing bowl, combine the quick oats, mini chocolate chips, and chopped peanuts (if using).

In a separate microwave-safe bowl, heat the peanut butter and honey together in the microwave for 30 seconds or until melted.

Add the vanilla extract and salt to the melted peanut butter and honey mixture and stir to combine.

Pour the peanut butter mixture over the dry ingredients and stir until the oats are fully coated.

Transfer the mixture to the prepared baking pan and press down firmly with a spatula or your hands until it is evenly distributed and tightly packed.

Chill the granola bars in the refrigerator for at least 30 minutes to set.

Once set, remove the granola bars from the pan using the parchment paper overhang and cut into desired sizes and shapes.

Store the granola bars in an airtight container in the refrigerator for up to one week.
