'Potluck' Marshmallow Bars

My brother and I were trying to figure out something to make with the bad of mini-marshmallows in the cupboard and we started discussing these treats known only as - those things with the rainbow marshmallows that we always had at potlucks. We both remembered them as being rainbow mini marshmallows covered in some sort of goo, which I remembered consisting of peanut butter and butterscotch and he remembered as including chocolate as well.

So, armed only with childhood memories, we went hunting. And we found this...

1 pkg butterscotch chips
1 pkg (about 2 cups) chocolate chips
1/2 cup peanut butter

1 pkg mini-marshmallows

Line 9x13 pan with tinfoil. Grease tinfoil. In a large bowl microwave together chocolate chips, butterscotch chips and peanut butter in 30s-1min intervals until melted. Add marshmallows. Pour into pan. Refrigerate until solid.

Okay, so we realized why these are brought to potlucks - because one or two is tasty but anymore gets a little much. So I don't know if I'll make them again.
