Rice krispie treats with tons of peanut butter flavor! There's peanut buttery goodness in the base, the topping, and garnish!
Lining the pan with parchment paper is optional, but it does allow you to lift the rice krispie treats out of the pan in one piece (just make sure to leave some extra parchment hanging out on either side to use as handles!). I found it easier to cut the rice krispie treats neatly when they are removed from the pan.
You can use a 9 x 13 inch pan instead of a 9 x 9 inch pan if you prefer. The treats will be thinner but you can also cut more servings. If using the 9 x 13 inch pan, I recommend using 15 ounces peanut butter chips and 3 tablespoons butter for the topping, so there is enough topping to cover the larger surface area.
The rice krispie treat mixture comes together very quickly once the marshmallows are melted, so it's very helpful to have all of your ingredients prepped and measured before you start the cooking process.
