That's not a "no no".
For this cake, you have to get the cake bottom hot enough to soften the sugar mixture. Then invert it right away onto a cake platter and leave it all together for a few minutes so any sauce can run off from the pan onto the cake. Then you should be able to lift off the cake pan.
In the future, transfer the cake to the serving plate as soon as it comes out of the oven.
You shouldn't need parchment but it wouldn't hurt.
