The invention relates to a method and an apparatus for producing a dough, in particular a dough for bread for toasting, by means of an extruder. The extruder has at least two extruder shafts along which kneading elements for admixing a gas into a dough are arranged in at least one kneading section. Gas can be drawn off along a gas-removal section and therefore a defined proportion of the gas is established in the dough. Furthermore, a mould for discharge of the dough is arranged at the output of the extruder. A nozzle device is arranged at an input region of the extruder, it being possible for said nozzle device to be used to spray a preparation liquid onto a dough base material under pressure in order to form a starter dough.
