Line 2 9×5 loaf pans with parchment, lightly spray with cooking spray, and set aside.
In a large saucepan over medium heat, melt the butter. Once the butter has melted add the brown sugar, honey and peanut butter and whisk until completely combined.
Bring the mixture to a boil, then lower the heat to medium-low and simmer until the sugar is completely dissolved, about 2 minutes. Remove the saucepan from the heat and add the vanilla extract. Stand back, it may foam a little.
Add the granola and rice krispies into the saucepan and fold them into the sugar mixture until the granola and rice cereal is completely coated. Fold in about half the chocolate chips (there will be some slight melting).
Spread the mixture into the prepared pan and press firmly with a spatula (or clean hands) to completely fill the plan. Top with remaining chocolate chips.
Allow the pans to site at room temperature for 20-25 minutes until mostly cooled and set. Lift and cut into bars.
Makes about 10 bars
