Delicious Chocolate Mousse Cake

Decorative Topping (optional)

Halloween decoration

10 grams soft butter

10 grams powdered sugar

10 grams egg white

10 grams flour

1. Mix the butter then add the powdered 
sugar, add the egg white then add the flour. 
Add coloring.

2. Draw your design on a sheet of paper and 
place under the  your parchment paper.

3. Put each color into a separate bag for 
piping. Your lines should be thin but not too 
thin, otherwise, they will not show up well 
after baking.

4. Put this in the refrigerator for about 20 
minutes so that the mixture becomes firm

I use a shallow square baking pan (27 cm x 
27 cm – height is 2 cm) covered with parchment paper to pipe the decoration on.

Strain into another bowl and lightly cool. The chocolate and egg mixture should be the same temperature.

Putting together

1. Let the cake cool and turn upside down to remove the parchment paper. Cut out the decoration and a matching bottom and put the bottom inside of a cake ring. 

2. Fill the ring with chocolate mousse the place the decorate piece on top. Put in the refrigerator for at least one hour before removing the ring.

Place one piece of cake at the bottom of the ring then add mousse almost to the top. Put on the last piece of cake & put in refrigerator.
