01 - Line an 8x8-inch baking pan with parchment paper, allowing overhang on two sides for easy removal later.
02 - In a large mixing bowl, add oats, rice cereal, dried apple, shredded coconut, chopped peanuts, cinnamon, and salt. Mix well to distribute evenly.
03 - Place peanut butter, honey, and coconut oil in a microwave-safe bowl or small saucepan. Warm gently until smooth and runny, stirring occasionally. Remove from heat and stir in vanilla extract.
04 - Pour the warm wet mixture over the dry ingredients. Stir thoroughly with a spatula until all components are evenly coated and the mixture holds together when pressed.
05 - Transfer the mixture to the prepared pan. Use a spatula or clean hands to press firmly and evenly, compacting the mixture tightly to ensure bars hold their shape.
06 - Refrigerate for at least 1 hour or until completely firm and set.
07 - Using the parchment overhang, lift the solid block from the pan. Cut into 12 equal-sized bars with a sharp knife.
08 - Keep bars in an airtight container in the refrigerator for up to 1 week for best texture and freshness.
