Cut bread into cubes of about 2 cm. Whisk eggs, sugar and vanilla sugar. Heat milk and double cream in a pot while stirring (do not boil!). Stir slowly into the egg mixture in a thin stream.
Fold in bread and let it stand for about 10 minutes.
In the meantime, select the blackberries and wash if necessary. Preheat oven (electric cooker: 175 °C/circulating air: 150 °C/gas: see manufacturer). Grease six ovenproof moulds (each approx. 8 cm Ø). Spread the bread mixture into the ramekins.
Add the berries and almonds. Bake in a hot oven for about 40 minutes. Remove from the oven and leave to rest for about 10 minutes. Cream tastes good with it.
