Method
Preheat the oven to 175 ° C. (Upper or lower heat or circulating air) Spread a baking pan with Ø 23 cm in diameter with coconut oil. Mix the flour, cocoa powder, soda, sugar and salt in a mixing bowl. Flour and cocoa powder seven, so there are no lumps.
Mix water, oil, vanilla and vinegar in a second bowl. Gradually add the water-oil mixture to the dry ingredients and mix with a blender to a smooth dough. For clumps you can add some water.

Approximately bake in the oven for 20-25 minutes until the cake topping bounces slightly when touched. First let cool, then remove from the mold and sprinkle with powdered sugar.
