I got this recipe from my sister who used to make it and sell to  classmates when she was in high school .

1 14 ounces condensed milk

1 tbsp melted butter

1 tsp vanilla extract

1/4 cup finely crushed skyflakes crackers

2 tbsp finely ground nuts (optional)

In a saucepan mix melted butter and milk together well. Cook over a low heat . Continue mixing it to avoid sticking.Add the crackers ,vanilla and nuts and continue cooking until the mixture is thick enough to shape into small ball.

Remove from the heat and transfer to a small bowl

Shape into small balls or form the shape you want.  start wrapping while its stilla a little bit hot so it will stick to the wrapper.
