Vintage Frozen Pumpkin Parfait Squares

As previous postings will attest, I love pumpkin. I have made this recipe from my mother many times. Before posting it today, I decided to google the recipe to see where it might have come from. Turns out it is a "vintage" recipe, according to one website I found. It came from the label of a can of Libby's pumpkin, a picture of which I've attached alongside my typed version of the recipe. There is much comfort to be found in vintage recipes! Please do send me your favourites!
