What each ingredient does

Pastry
Forms a sealed wrapper that holds the filling and gives a tender, crisp or flaky outer layer.
Treacle
Adds sweetness, dark colour and a rich, sticky flavour to the filling.
Bread crumbs
Absorb the treacle so the filling stays soft and spreadable instead of running out.
Butter or clarified fat
Greases the cloth or tin so the roll releases cleanly and adds richness.

The step that matters

Roll the pastry up tightly and pinch the edges. A loose roll or unsealed edges let the treacle leak out during cooking, leaving the roll dry and the filling scattered. Moistening the edges helps them bond into a firm seal.
