Set aside a few slices of bread to place on top of the pudding, and cut the rest into cubes. Place the cubes in the bottom of a baking dish and lay the reserved slices on top.

Whisk the eggs with the milk and 2 tablespoons of sugar, then pour the mixture over the bread. Let it soak for 10 minutes so the bread absorbs the liquid.

Preheat the oven to 325°F (160°C). Sprinkle the remaining 2 tablespoons of sugar and the raisins on top, then bake for about 20 minutes. Serve warm.
