Mix butter, sugar and whole eggs well. Then add the remaining ingredients. The whole thing comes on a baking tray and is baked at 170 degrees for about 25 minutes top and bottom heat.
After the cake has cooled a little, the icing sugar-rum mixture comes on it.
Preparation Tip:
The icing can of course be colored wonderfully. So that the glaze drips beautifully, do not skimp on the rum!
