Before starting this recipe - make sure you freeze the ⅔ cup of mini chocolate chips. This helps to prevent them from melting while mixing into the warm oats! Line a 9x9 brownie pan with parchment paper.
In a large bowl, mix together the oats and cereal. Set aside.
Add the brown sugar, maple syrup, peanut butter, coconut oil, vanilla extract, and salt to a saucepan.
Melt this mixture on low heat, stirring constantly, until it's silky smooth.It will begin gently bubbling; this is okay. Pour the warmed sauce over your oats and cereal. Stir well until the mixture is moist.
Time to work fast!Stir in the frozen chocolate chips and shredded coconut. Pour the granola mix into the lined brownie pan, and press it into an even layer using another sheet of parchment paper so your hands don't stick.
Refrigerate for at least 45 minutes. The bar will be solid.
Lift the parchment paper and granola block out of the pan, then carefully cut the block into 12 even rectangular pieces.See recipe notes for tips and tricks on how to cut without breaking too many bars! Pop the cut bars back into the fridge to set (if needed), while you melt the remaining chocolate chips and coconut oil together in a microwave.Use 20-second intervals so you don't burn the chocolate. Stir after each time. Dip the bottom of each bar into the chocolate and place on a parchment-lined sheet tray.
Add the remaining melted chocolate to a pastry bag or plastic storage bag, snip the corner, and drizzle onto the tops of the bars.
Set the finished granola bars into the fridge once more to fully set.
Store them in the refrigerator in a sealed container. Enjoy!
