In a food processor/blender, blend the peanut butter and milk together until smooth.

Preheat your broiler and arrange marshmallows on a parchment-lined baking sheet. Toast marshmallows until they've browned/blackened to your preference. Watch them closely as they can go from nicely browned to black and burnt really quickly.

Once toasted, immediately use a spatula to scrape the marshmallows into the food processor/blender, blending until smooth. Add the ice cream and continue blending until combined. Place milkshake into the freezer while you prepare the glasses.

Using a butterknife, spread strips of peanut butter along the bottom of a glass (see photo above). Spread a layer of peanut butter onto the rim of the glass--about an inch or so in width. Press Reese's Pieces, peanut butter chips, and Nutter Butter cookies into the peanut butter rim. Skewer two marshmallows with a straw and toast with either a mini blowtorch or gas stove. Repeat once more with a second glass

Divide milkshake between the two glasses. Top with whipped cream, more candy/cookies, and marshmallow sauce. Insert the toasted marshmallow straw. Enjoy!
