Place butter, sugar, water, cocoa powder, and vanilla sugar in a pot. Put on low heat and stir until all ingredients combine and sugar has melted well. Don’t stop stirring so the sugar won’t burn on the bottom of the pot
Save half a cup of the cocoa butter on the side and let the rest cool down a bit
Preheat oven to 180. Grease with butter and dust with flour your baking pan. I use 22x12 and 5cm deep. It’s ok if your pan is a bit longer or deeper. Mine grows quite high
In the bowl mix flour and baking powder. Mix to combine with whisk, spatula or spoon. Pour your cocoa butter and mix it together by adding gradually eggs. One at the time. If you want to add nuts this is your cue to do so
Pour the mixture into earlier prepared baking pan and bake for 35-45min. you can check if it’s done with a wooden stick. If it comes out nice and dry the bake is done
Let it cool a bit and remove it from the form. Place on cooling rack and pour over earlier saved chocolate sauce. Make sure you have a plate underneath to prevent from the mess. Let it set
All done. Cut into 2 cm slices and enjoy with a nice cuppa
Notes
Tip: If you want an extra crunch you can add roughly chopped 2 cups of walnuts or almonds.
