Combine the homemade sweetened condensed milk and sifted cocoa powder in a mixing bowl. While mixing, add cocoa powder in portions wise. Mix well to make dough.

If the dough is still too sticky or wet, add more cocoa powder, or if it is too dry, add condensed milk. Or you can apply your hands with bit of oil or butter while kneading.

Knead to make a smooth non-sticky dough.
Keep butter paper or silver foil at the bottom of a square or rectangular airtight container. Now spread the truffles mixture on the butter paper.

Spread evenly with your fingers to get square shaped truffles and cover with butter paper or foil.

Sprinkle roasted dry fruits powder or cocoa powder for garnish. (optional)
