Chocolate Peanut Butter Stained Glass Bars

 A retro treat that requires no baking!

1/3 cup unsalted butter

2 cups semi-sweet chocolate chips, divided

1/3 cup creamy peanut butter

3 tbsp unsweetened cocoa powder

2 tsp pure vanilla extract

1/2 tsp kosher salt

1 bag (400 g) multicoloured miniature marshmallows, about 10 cups

1 cup salted peanuts, roughly chopped

2/3 cup flaked sweetened coconut

* Spray a 9 inch square pan with cooking spray, then line with parchment paper to reach 1 inch above edges

* Melt butter in a medium saucepan set over medium heat.  Cook, without stirring until light brown and slightly nutty, about 3 minutes.  Remove from heat and scrape up any browned bits with a wooden spoon.  Cool for 2 minutes

* Add 1/2 cup chocolate to butter and stir until melted.  Repeat with remaining chocolate chips in 2 stages.  Stir in peanut butter, cocoa, vanilla and salt until dissolved and smooth.  Cool completely about 20 minutes.  

* Place marshmallows and peanuts in a large mixing bowl.  Pour cooled chocolate mixture overtop and gently stir to coat; spread into prepared pan to fill each corner without smooth top.  Sprinkle with coconut if using.  

* Refrigerate for at least 3 hours, preferably overnight.

*Grabbing sides of parchment paper, remove bars and transfer to cutting board.  Cut into squares or slices  and store in an air tight container and refrigerate.
