This is a no bake dessert from my childhood: one of the easiest to do (you can do it with you child together) with ingredients which were easily available at that time. I think I grew up with condensed milk, cookies and butter.
We called these “sweet potatoes”, I guess mostly because of the color and form. I think the closest equivalent to this recipe in English would be “rum balls” if you make them with rum and form balls instead of “potato” shapes.
Of course, if you make this dessert for kids, skip alcohol.
