This is a favourite recipe of our family that I make for almost all holidays and get togethers. They are always in demand and usually the first dessert item to go. They look great on platters with Christmas cookies and squares, and are super easy to make for a cookie/square exchange (as long as peanut-free is not a concern.)

1/4 cup butter
1/2 cup smooth peanutbutter
1 package butterscotch chips
3 cups coloured miniature marshmallows
Place butter, peanutbutter and butterscotch chips in a pan on medium-low heat. Stir CONSTANTLY until melted and smooth. Remove from heat and let cool 20 minutes. After cooling, stir in miniature marshmallows. Pour into a butter greased 8 inch square pan, plastic, or glass container. Chill in fridge until firm (a few hours.) Cut into squares (not too big as they are quite sweet) and serve. They freeze quite well.
I always make a double batch by doubling all ingredients and chilling in a 9x13 glass baking dish.
The photo is not mine, I found it on the internet. photographer unknown, as I keep forgetting to take photos when I make them and they are eaten so quickly.
