01 - Line an 8x8-inch baking pan with parchment paper, allowing some overhang for easy removal of the bars later.
02 - In a large bowl, combine the 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 the vanilla extract.
04 - Pour the warm wet mixture over the dry ingredients. Stir thoroughly to ensure all ingredients 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 firm and set.
07 - Lift the bars from the pan using the parchment paper overhang. Cut into 12 equal bars and serve immediately or store for later.
