Wrap bananas unpeeled in aluminium foil and bake in a preheated oven (electric cooker: 200 °C/circulating air: 180 °C/gas: see manufacturer) for 25-30 minutes.
In the meantime, let your mind wander a little. Take the bananas out of the oven, let them cool down briefly, unpack them and scrape the bananas out of their skins with a spoon.
Mix the bananas in a mixing bowl with sugar, vanilla sugar and brown sugar to a puree. Stir in whole milk yoghurt and lime juice - until you have a creamy mixture. Then stir in white rum.
If you only have brown at home right now, you can also take this one.
Fill the banana-rum mixture into 16-20 small moulds and press a wooden stick halfway into each mould. Put in the freezer for about 20 hours. Wait, wait, wait or throw a small Rumfete in the time.
The next day, dip the ice cream cups in a hot water bath for 5-10 seconds, drain them on a tea towel and carefully pull the ice cream out of the cups. Cheers!.
