01 - Line an 8x8-inch baking pan with parchment paper, leaving overhang on sides for easy 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 until smooth and pourable, stirring between each. 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 press until all oats and cereal are evenly coated with the sticky mixture.
05 - Transfer mixture to the prepared pan. Press down firmly and evenly with a spatula or the back of a measuring cup to compact the bars tightly.
06 - Refrigerate for at least 1 hour until firm and completely set. Bars will hold their shape better when fully chilled.
07 - Using the parchment overhang, lift the entire slab from the pan. Cut into 12 equal bars with a sharp knife. Store in an airtight container in the refrigerator for up to 1 week.
