At first you should design your hedgehog (or whatever animal you like) with a CAD Program. In this case it is absolutely unneccecary to draw the product first, but if your cake is getting a more comlicated shape, you can just print it to cut the form out of the dough.
If you own a Cake Cutter than you can just cut the dough directly from the computer!
So here I just took the measures and cut out a cardboard-template.
Step 1: The Shortcrust
a pinch of salt
knead the shortcrust dough out of it, wrap it in aluminium foil and put it into the fridge for two hours.
After that you roll out the dough with a thickness of 5mm and use the cardboard to cut it in pieces.
Bake it at 200°C for 8-10 minutes.
Step 2: The Cream
1/2 Sachet of blacmange powder
1 Egg yolk
3 Tablespoons of cocoa
Take the blacmange powder and mix it with 3 tablespoons of milk and the egg yolk. Heat up the rest of the milk with the sugar. If it is boiling, put the blacmange into the milk, mix it and boil it again.
Beat the butter until light and put it gently into the blacmange, when they have the same temperature.
If this is done, take aside some tablespoons of the cream and add the cocoa to the rest of it.
Step 3: Forming the Hedgehogs
Step 4: Chocolate!
Congratulations to your first computer developed choco-vanilla-butter-cream hedgehogs!!!!
