01 - Line an 8x8-inch baking pan with parchment paper, allowing overhang on opposite sides for easy bar removal later.
02 - In a large mixing bowl, add rolled oats, crispy rice cereal, chopped dried apple, shredded coconut, peanuts, ground cinnamon, and salt. Mix thoroughly to distribute spices evenly.
03 - Combine peanut butter, honey, and melted coconut oil in a microwave-safe bowl. Heat in 20-second intervals, stirring between each, until mixture is smooth and pourable. Remove from heat and stir in vanilla extract.
04 - Pour the warm peanut butter mixture over the dry ingredients. Use a spatula to fold and mix until all dry components are evenly coated with the wet mixture.
05 - Transfer the mixture to the prepared pan. Press firmly and evenly using the back of a spatula or clean hands, compacting tightly to ensure bars hold together properly.
06 - Refrigerate the pan for at least 1 hour or until bars are completely firm and set throughout.
07 - Using the parchment overhang, lift the solid block from the pan. Cut into 12 equal-sized bars with a sharp knife. Store in an airtight container in the refrigerator.
