Mix the butter with the sugar until frothy. Add the vanilla pulp and the grated orange peel. Sieve wheat starch and flour with baking powder and stir in alternately with the eggs. Mix in the orange juice and chocolate droplets.
Line a loaf pan (1 ½ liter content) with baking paper, fill in the dough and bake for about 45 minutes at 160 ° C. If the cake has a small skin (after approx. 10 minutes) carefully cut in the middle with a sharp knife so that the cake can rise evenly.
For the glaze, bring the cream to the boil and melt the chopped couverture in it. Mix well and cover the cooled cake with the warm glaze.
