Start of by grabbing an 8x8 baking dish and spraying it with cooking spray. Set this aside.
Grab a large pot and place it on the stove on medium heat. Add your butter and allow it to melt.
Once the butter has melted, add in the peanut butter and mini marshmallows and stir these frequently to melt. Don't let it burn! Slow and steady.
Once the butter, peanut butter and marshmallows have melted and combined, it is time to add in you rice krispies. Add these in gradually and stir to evenly distribute.
Once evenly distributed and all of the marshmallow mixture has coated the rice krispies, transfer to your baking dish and spread out evenly.
Time to make your top coat! Melt the peanut butter and white chocolate wafers in a bowl using the microwave or the stove, stir together well and then pour over the rice krispies, smoothing it out with the back of s poon to even it out.
Place these in the fridge for a few hours to set before cutting in to squares and enjoying.
