As fun to say as they are to eat – these yummy Scotcheroos are packed with peanut butter, marshmallows, chocolate, and butterscotch, an easy crispy cereal treat that you won't be able to get enough of!
Line a 9x13 inch pan with foil or parchment and preheat oven to 350 while you move on to next step.
In a large pot over medium heat, melt butter.
Reserve 2 cups of marshmallows and set aside. Stir remaining marshmallows into the pot.
Add peanut butter and stir until marshmallows are completely melted and mixture is smooth.
Stir in vanilla and salt, then stir in reserved marshmallows for 1 minute until semi-melted. Stir in cereal.
Spread into prepared pan, pressing down slightly (not too much) to create an even layer in the pan. (see tip)
Sprinkle milk chocolate and butterscotch chips all over the top and transfer to preheated oven for 5-10 minutes until chocolate/butterscotch chips are semi-melted.
Use a spoon or spatula to spread chocolate/butterscotch into an even layer. Allow to cool completely before cutting into bars and serving or storing in airtight container.
Spreading into pan: spritz a rubber spatula with nonstick spray before using to spread/press gooey cereal mixture into the pan. Cooling the bars: to speed up the process of cooling, I usually put my pan into the fridge for 10 minutes or so.
