In a large non-stick pot over medium heat, melt butter. Add in marshmallows and stir together with butter until marshmallows have melted and become creamy. Stir in vanilla extract and peanut butter, until smooth.

Fold in grahams cereal until all marshmallows and grahams are evenly mixed together. When the mix becomes very sticky (and has cooled slightly – it will be harder to stir) mix in the  chocolate chips and peanut butter chips. Spread treats into sprayed baking pan. Press into pan and sprinkle remaining  chocolate chips and peanut butter chips on top of the treats, lightly press into top of treats to make sure they stick. Place into fridge for 10-15 minutes to cool.

Slice into bars and serve. Devour.

(Pro Tip – spray your hands and spatula with non-stick spray to make sure the marshmallow doesn’t stick to your hands)
