Place 8 Bourbon biscuits onto a baking tray and warm in the oven for 3 minutes at 180°C. Once warm, carefully separate each biscuit into two halves, creating 16 biscuit halves. Set aside for decoration.

Crush the remaining 450g of Bourbon biscuits into fine crumbs and place in a large bowl. Add the melted butter and 120ml of the condensed milk. Mix thoroughly until it forms a wet, dough-like consistency.

Press the biscuit mixture firmly into the lined tin, creating an even base layer.

Break the milk chocolate into small pieces and place in a saucepan with the remaining condensed milk. Heat gently over low heat, stirring continuously until the chocolate has completely melted and formed a thick, glossy mixture.

Pour the chocolate mixture over the biscuit base and spread evenly to the edges. Arrange the Bourbon biscuit halves on top in 3 rows of 5 pieces.
