Cut bread into cubes (approx. 2 cm). Whisk eggs, sugar and vanilla extract. Heat milk and double cream in a pot while stirring until boiling. Add to the egg mixture drop by drop while stirring.
Fold in the bread cubes and let them stand for about 10 minutes. In the meantime, sort out the blackberries.
Divide the mixture into 6 greased ovenproof dishes (approx. Ø 8 cm). Add blackberries and sprinkle with almonds. Bake in the preheated oven (electric cooker: 175 °C/ convection oven: 150 °C/ gas: see manufacturer) for approx. 40 minutes.
Take out and let it rest for about 10 minutes. Whipped cream tastes good with it.
