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 cake pop moulds half-full with the mixture.
Cut the butter cake into small cubes and press into the mixture.
Finish filling the moulds and insert a lollipop stick.
Freeze.
