01 - Line an 8x8-inch baking pan with parchment paper, leaving some overhang for easy removal later.
02 - In a large bowl, mix together oats, rice cereal, dried apple, shredded coconut, chopped peanuts, cinnamon, and salt until well blended.
03 - In a microwave-safe bowl or small saucepan, gently warm the peanut butter, honey, and coconut oil until smooth and runny. Remove from heat and stir in vanilla extract.
04 - Pour the warm wet mixture over the dry ingredients. Stir thoroughly to ensure all components are evenly coated with the peanut butter mixture.
05 - Transfer the mixture to the prepared pan. Using a spatula or your hands, press firmly and evenly to compact the mixture tightly.
06 - Refrigerate for at least 1 hour or until the bars are completely firm and hold together well.
07 - Lift the bars from the pan using the parchment paper overhang and cut into 12 equal-sized bars.
08 - Store in an airtight container in the refrigerator for up to 1 week for best texture and freshness.
