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 oats, crispy rice cereal, chopped dried apple, shredded coconut, peanuts, cinnamon, and salt. Mix well to distribute evenly.
03 - Combine peanut butter, honey, and melted coconut oil in a microwave-safe bowl. Heat in 20-second intervals, stirring between each, until smooth and pourable. Stir in vanilla extract.
04 - Pour the warm wet mixture over the dry ingredients. Fold and stir thoroughly until all dry components are evenly coated with the peanut butter mixture.
05 - Transfer the mixture to the prepared pan. Using the back of a spatula or clean hands, press down firmly and evenly to compact the bars tightly.
06 - Refrigerate the pan for at least 1 hour until the bars are completely firm and hold their shape when cut.
07 - Lift the slab from the pan using the parchment paper overhang. Cut into 12 equal 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.
