Preheat oven to 350 F (180 C). Line 12 muffin cups with paper liners or spray generously with nonstick cooking spray. Grease top of the muffin pan.
Line a baking sheet with parchment paper. Set aside.
Pour all but 2 cups (500 mL) of the bread cubes in a large bowl. Add milk and cream and let stand for 3 minutes, then stir to mush up some of the cubes and let the liquid soak inches Stir in eggs, sugar, vanilla, brandy and butter.
In a small bowl, stir together flour, baking powder, salt and cinnamon, then stir into wet ingredients. Add raisins and stir well to make a chunky butter. Stir in reserved breads cubes just to mix.
Using a large ice-cream scoop, fill each muffin cup to just over rim. Place muffin pan on prepared baking sheet.
Bake for 30 minutes or until muffins are golden with tips of firmer bread cubes golden brown. Let cool in pan 5 minutes. Unmold onto a serving platter on wire rack, dust with icing sugar.
