Serve a frighteningly good brownie on the scariest day of the year. This will go straight to the homes of both young and old.

How to do it:

1. Preheat the oven to 175 degrees above and below.
2. Melt the butter and remove from the heat. Add the chocolate and leave for a minute or two. Stir until the chocolate has melted. Whisk in the cocoa and sugar. Beat in one egg at a time and finally stir in the vanilla, salt and flour. Coarsely chop the walnuts and fold in together with the chocolate drops.
3. Pour into a small greased long pan and bake in the middle of the oven for 30-35 minutes. The cake should not be completely cooked through. Test with a skewer or toothpick. There should be some moist crumbs on the stick when it is finished.
4. Cool completely before putting on the cream cheese, otherwise the cream will melt.
5. Whisk the butter, vanilla, orange juice and 70 g caster sugar into a fluffy cream. Finally, whip in the cream cheese. If you want a sweeter cream, you can whip in a little more icing sugar. 
6. Put the cream cheese in a piping bag with a round tip and spray ghosts on the brownie. Start by making a small round body and finish with a tip like a tail. It can be worthwhile to practice a little on a plate before you decorate the brownie. If the cream is too thick, you can whip in more orange juice.
7. Melt the chocolate over a water bath and transfer to a small piping bag or make a creamer's house out of food paper. Spray little shocked mouths on the ghosts, and use the chocolate or ready sprinkles for eyes.
