Method

Batter

  1. Preheat the oven to 350°F (180°C) convection (fan).

  2. Beat the butter with the salt, vanilla sugar and sugar for a few minutes until light and creamy.

  3. Beat in the eggs one at a time.

  4. Combine the flour and baking powder and stir them in as briefly as possible, then spread the batter onto a large baking sheet lined with parchment paper (about 16 × 14 inches / 40 × 35 cm; a US half sheet pan, 18 × 13 inches, works too).

  5. Scatter the fruit over the batter.

Streusel

  1. Rub the butter, sugar, flour, salt and vanilla sugar together into streusel and scatter it over the sheet.

  2. Bake until golden, then let it cool and, if you like, dust with a little powdered sugar (very finely ground sugar for icings and dusting; in the US, powdered sugar or confectioners' sugar; in the UK, icing sugar).
