      TM 5
      Please note that the TM5 mixing bowl has a larger capacity than the TM31 (capacity of 2.2 liters instead of 2.0 liters for TM 31). Recipes for the Thermomix TM5 may not be cooked with a Thermomix TM31 for safety reasons without adjusting the quantities. Risk of scalding by spraying of hot liquids: Do not exceed the maximum filling quantity and observe the filling level markings of the mixing bowl!

Recipe's preparation

  1. 1,- Preheat the oven to 180 C. Butter the cake tin of around 20 cms and line the base and sides with non stick paper.
    2,- Add the sugar to the and grind 1 min/Speed 10
    3,- Add the butter, salt and vanilla mix 1 min/speed 4
    4,- Insert the butterfly and whisk 2 min/speed 4
    5,- Add the eggs and mix 3 min/speed 4
    6,- Add the flour and the baking powder and mix 1 min/speed 4. Remove the butterfly and put the cake mixture in a big bowl.
    7,- In a mediun sized bowl weigh 250 grs of cake mix and add to it 1/2 tsp of 1 of the food colourings. Mix really well. Repeat it again with all the other colours and 250 grs of the cake mixture each time (depending on the type of food colouring that you use you will need more of it. the cake mixture must be really well dyed with intense colours. I use Wilton colous, which are fantastic). If you only have 1 tin cover all the other bowls with cling film whilst the tin with the first colour is in the oven.
    8,- Put in the oven for 12 minutes (180 C). Check that your cake is ready to come out by inserting a squeewer in the midlle of your cake. Take the cake out of the tin, with care, and leave it to cool in a wire rack. Repeat the same with all the other cake mixtures. let them cool down for at least 1 hour.
    9,- If needed serrate the top of the cakes to make sure that they are all the same size and they are flat at the top (they should be approx 2cm tall).

    To make the icing cream to cover the cake:
    10,- Add the chocolate to the and grate 15 sec/speed 7. Use the spatula to clean the sides of the .
    11,- Add the butter and melt 2 min/50 C/ speed 3
    12,- Add the cream cheese, the orange juice, icing sugar and mix 15 sec/speed 5. Use the spatula to clean the sides of the to the bottom of the and mix 20 sec/speed 6. Remove this mixture into a bowl.

    To put the cake together
    13,- Spread a tsp of the icing cream into a plate (it helps the cake not to slip). Put on top the puple cake. With a flat spatula cover the top of the first cake with a thin layer of the icing cream (about 2 tbsp). Making sure that no crumbs are spread around. Cary on in this order green, yellow, orange and red. Cover the top and sides of your cake with the icing cream trying to keep it as flat as possible. Leave in the fridge until you are ready to serve.

If you have more cake tins which are the same size you can shorten the time, as you can put them in 2's or 3's in the oven.
If you want the icing to be really neat and flat, add fisrst a very thin layer of the icing and put your cakes in the freezer for 15 minutes and then finish covering yor cake with the rest of the icing.
