Slice the vanilla lengthwise and scrape the seeds out.
1 vanilla bean
Heat the milk in a saucepan over medium heat together with the vanilla bean and seeds. Whisk a few times to break apart the vanilla seeds that are stuck together. Once the milk is hot, about 2 minutes, remove it from the heat and set it aside for at least 30 minutes to give the vanilla time to infuse. You can also store it in the fridge for up to 12 hours.
480 ml milk
Note! If using vanilla paste or vanilla extract, skip the steps above. You don't need to warm the milk and add the vanilla paste or extract straight to the custard.
Preheat the oven to 350F (180C).
Cut the brioche into about 1-inch (2.5cm) cubes and place them into the baking dish.
380 grams brioche bread
In a bowl, whisk the eggs and both sugars just until combined.
4 egg, 100 grams granulated sugar, 100 grams light or dark brown sugar
Mix in the melted butter.
56 grams melted butter
Remove the vanilla bean from the milk. Whisk the milk into the egg mixture.
Pour the custard over the brioche. Make sure all the pieces are soaked.
Add the white chocolate and raspberries over the top and gently mix them in.
100 grams white chocolate, chopped, 200 grams frozen or fresh raspberries
Bake on the middle rack for 30 minutes, or until the custard is set/absorbed and the top is starting to brown.
Remove from the oven, dust some powdered sugar on top, serve, and enjoy.
1 tablespoon powdered sugar
