01 - Line an 8x8-inch baking pan with parchment paper, leaving some overhang for easy removal later.
02 - In a large bowl, combine oats, rice cereal, dried apple, shredded coconut, chopped peanuts, cinnamon, and salt. Mix well to distribute evenly.
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 wet mixture over the dry ingredients. Stir thoroughly, ensuring everything is 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 completely firm and set.
07 - Lift the bars from the pan using parchment overhang and cut into 12 equal bars. Store in an airtight container in the refrigerator for up to 1 week.
