Mix the first 8 ingredients into a cake batter (leave out the cocoa for now). Pour some batter into the glasses. For jars with a capacity of 230 ml, one tablespoon of dough is sufficient. Add the cocoa to the rest of the batter and stir in. Distribute the dark dough evenly on the glasses.
Bake the cakes at 160 ° C (hot air) for about 30 minutes (stick test)
If you close the jars that are still warm, the cake should keep for up to three months. I haven`t tested this yet.
