Hold the bottle of Cheesecake under hot water for at least 20 seconds to loosen the contents from the bottle.
Empty the bottle into the bowl of the planetary mixer and beat with the whisk for 5 minutes at full speed until light and airy.
Transfer the mixture to a smooth-nozzled piping bag and fill the silicone moulds with the cheesecake mixture.
Cover with a slice of brownie.
Freeze the cakes so as to be able to turn them out and leave to thaw in the refrigerator.
