Line a loaf pan with parchment paper and set aside.
Add puffed rice cereal and chopped pecans to a medium-sized bowl, mix well and set aside.
In a small saucepan, add coconut oil, 1/4 cup of peanut butter, maple syrup, and cocoa powder and heat over medium. Whisk continuously to incorporate all of the cocoa powder and melt peanut butter, approximately 2 minutes.
Pour the chocolate mixture over the rice cereal and pecans and gently mix to coat all of the cereal.
Pour coated cereal into the loaf pan and spread to an even layer.
Add loaf pan to freezer to set for 30 minutes.
Meanwhile, create the peanut butter drizzle by adding the peanut butter, oil, and confectioner's sugar to a small bowl and whisking until creamy.
After at least 30 minutes, remove the loaf pan from the freezer and pull out parchment paper, and place set crunch bars on a cutting board. Use a knife to cut into 9 bars.
With a spoon, drizzle the peanut butter mixture over the top of the crunch bars.
Store in the fridge and enjoy!
