A simple no bake recipe for butterscotch marshmallow bars with coconut and walnuts! This is a classic holiday no bake treat!

I’m not the biggest fan of butterscotch.

I’m actually the type of person who would prefer to make special k bars without the butterscotch chips.

But, oh man, has my mind changed about butterscotch when it comes to these bars!!

I’m convinced that it has to do something with the combo of peanut butter, marshmallows and butterscotch all together that make the butterscotch less butterscotch-y.. which in my opinion is usually too sweet. Instead all I taste is creamy, marshmallowy goodness with a subtle crunch from the walnuts.

This recipe can go by a lot of different names – peanut butter marshmallow bars or squares, no bake nut goodie bars, and confetti squares, although I think those are generally made with the fruity marshmallows.

Whatever you choose to call them, they are a popular dessert to make for the holidays and to include in cookie tins!

Ingredients

  • butterscotch chips
  • creamy peanut butter
  • butter
  • mini marshmallows
  • walnuts
  • shredded coconut

It’s a quick recipe that comes together within 5 minutes and probably takes about an hour to set before you can cut them into bars. But you can speed up the cooling time by sticking the bars in the fridge! Or if you’re a midwesterner, you can put them in your garage or on your porch, which acts as a second fridge all winter season.
