For the dough, mix the flour with the baking powder and sugar in a bowl. Dice the butter, add with the egg and milk and knead everything into a smooth dough.
Preheat the oven to 225 ° C top / bottom heat.
Roll out the dough on the lightly floured work surface into an approx. 25 cm circle. Lift onto a baking sheet lined with baking paper. Peel the kiwis, cut into slices and place on the cake base, pressing lightly into the batter. Place the cake in the oven on the lower rack and bake for about 10 minutes.
In the meantime, put the ingredients for the glaze in a small saucepan and bring to the boil while stirring constantly.
Take the cake out of the oven and spread the butter icing on top. Reduce the oven heat to 200 ° C and bake the cake until golden for another 10 minutes.
Tips: If you double the amount of ingredients, the recipe is just enough for a small baking sheet.
You can also freeze the whole cake whole or in pieces. Shelf life about 2 months.
