Method for baking a baking mixture in at least one closed baking mould consisting of coated aluminium foil, comprising the following steps: a) producing a baking mixture, in particular a cake mixture, and exposing the baking mixture to at least one inert gas and/or air, the density of the baking mixture after exposure to the inert gas and/or air being between 0.4 and 0.8 g/cm 3, b) introducing the baking mixture into the at least one baking mould and closing said at least one baking mould, c) baking the baking mixture in the at least one closed baking mould in at least one reactor, wherein - in a first phase (phase 1) a reactor pressure is built up to values between 120 kPa and 400 kPa over a period of 3 to 30 minutes at a reactor temperature between 80°C and 300°C, the reactor pressure at any time point corresponding to the internal pressure in the closed baking mould, - in a second phase (phase 2) the reactor pressure is held at values between 120 kPa and 400 kPa at a reactor temperature between 80°C and 300°C for a period of 5 minutes to 200 minutes, during which phase the baking mixture is baked, and - in a third phase (phase 3) the reactor pressure is reduced incrementally to values between 100 kPa and 120 kPa while at the same time reducing the reactor temperature to 20°C to 100°C, the reactor pressure at any time point corresponding to the internal pressure in the closed baking mould, and d) removing the at least one closed baking mould containing the baked good from the reactor. a) producing a baking mixture, in particular a cake mixture, and exposing the baking mixture to at least one inert gas and/or air, the density of the baking mixture after exposure to the inert gas and/or air being between 0.4 and 0.8 g/cm 3, b) introducing the baking mixture into the at least one baking mould and closing said at least one baking mould, c) baking the baking mixture in the at least one closed baking mould in at least one reactor, wherein - in a first phase (phase 1) a reactor pressure is built up to values between 120 kPa and 400 kPa over a period of 3 to 30 minutes at a reactor temperature between 80°C and 300°C, the reactor pressure at any time point corresponding to the internal pressure in the closed baking mould, - in a second phase (phase 2) the reactor pressure is held at values between 120 kPa and 400 kPa at a reactor temperature between 80°C and 300°C for a period of 5 minutes to 200 minutes, during which phase the baking mixture is baked, and - in a third phase (phase 3) the reactor pressure is reduced incrementally to values between 100 kPa and 120 kPa while at the same time reducing the reactor temperature to 20°C to 100°C, the reactor pressure at any time point corresponding to the internal pressure in the closed baking mould, and - in a first phase (phase 1) a reactor pressure is built up to values between 120 kPa and 400 kPa over a period of 3 to 30 minutes at a reactor temperature between 80°C and 300°C, the reactor pressure at any time point corresponding to the internal pressure in the closed baking mould, - in a second phase (phase 2) the reactor pressure is held at values between 120 kPa and 400 kPa at a reactor temperature between 80°C and 300°C for a period of 5 minutes to 200 minutes, during which phase the baking mixture is baked, and - in a third phase (phase 3) the reactor pressure is reduced incrementally to values between 100 kPa and 120 kPa while at the same time reducing the reactor temperature to 20°C to 100°C, the reactor pressure at any time point corresponding to the internal pressure in the closed baking mould, and d) removing the at least one closed baking mould containing the baked good from the reactor.
