Add instant malted milk powder.
In a large bowl whisk together 5 1/2 cups of flour, cinnamon and salt. Add in the liquid and mix until combined.
Add extra flour if dough is too sticky to knead.
Knead dough with a bread hook attachment in a mixer or by hand until smooth (5-10 minutes). Fold in the raisins by hand to evenly distribute throughout the dough.
