1grease a 8x8 pan with butter set aside.
In a pot over medium heat add butter and marshmallows and stir until completely melted.
2Remove from heat and add pretzels, stir to coat well, then add in chocolate and peanut butter chips ( they will melt) stir well then add to 8x8 greased pan. Press down evenly ( I used a piece of parchment paper to press then down) Let cool on the counter for about 15 minutes then place in fridge for 30 minutes to 1 hour.
3Cut into the size squares you want and serve.
**** Do not crush the pretzel up to fine****
