    • 250g (8oz) butter
    • 250g (8oz) light soft brown sugar
    • 175g (6oz) black treacle
    • 500g (1lb) rolled oats
    • 18 x 28cm (7 x 11in) tray bake tin, lined with baking parchment


    • Set the oven to 180°C (gas mark 4).

    • Cut the butter into cubes and place it in a saucepan along with the soft brown sugar and treacle. Place the pan over a low heat and stir until all the butter and sugar have melted.

    • Pour the melted mixture into the oats and mix well. Tip the mixture into the lined tin and level it out and press it down well.

    • Bake the tray bake in the centre of the oven for 40-50 mins, until it’s starting to turn a darker colour around the edges.

    • Remove the tray bake from the oven and mark it into 12-14 fingers, then leave the flapjack to cool in the tin.

    • When cold, use the lining paper to lift the flapjack out of the tin and then cut or break along the marked lines.
