01 - Line an 8x8 inch baking pan with parchment paper, leaving edges overhanging for easy bar removal later.
02 - In a large mixing bowl, add rolled oats, chopped nuts, dried fruit, and chocolate chips. Toss gently to distribute evenly.
03 - Place peanut butter, honey, and butter (or coconut oil) in a small saucepan over low heat. Stir continuously until melted and smooth, then remove from heat.
04 - Whisk vanilla extract and salt into the warm wet mixture until fully incorporated.
05 - Pour the warm liquid over the dry ingredients. Stir thoroughly until all oats and add-ins are completely coated with the peanut butter mixture.
06 - Transfer the mixture to your prepared pan. Press down firmly using a spatula or the back of a spoon to create a compact, even layer.
07 - Refrigerate for at least 1 hour until firm and set completely.
08 - Lift the bars from the pan using the parchment paper handles. Cut into 12 equal rectangles. Store in an airtight container in the refrigerator.
