How to make cream puffs:
Place the mixture in a pastry bag with a smooth nozzle and form little tufts of dough on a baking tray lined with baking paper;

Preheat the oven to 200 degrees and bake the cream puffs in the middle;
Cook without ever opening the oven for about 25 minutes, during this phase you will see the cream puffs swell and brown;
When they are nice and puffy after 25 minutes you can lower the temperature to 180 degrees and continue cooking for another 5 minutes;
