how to make rainbow cake with vanilla buttercream icing

Pre-heat oven at 160°C. It's a slow-bake cake.

Grease & flour a 7 inch diameter round baking dish.

Sieve flour & salt. Keep aside.

In a bowl, add margarine + sugar & mix well with a mixer at high speed till fluffy and creamy.

Add the eggs + vanilla & mix well till well combined & mixture looks curdy.

Add the flour mixture & mix well till all combined.

If mixture is too heavy, add the water & mix well on high speed.

Take 7 bowls. Scoop using a serving spoon, the cake mixture & distribute evenly in the bowls. Repeat till all the mixture is used up.

Now add the food colouring. Red, orange, yellow, green, blue, pink, purple. Different colour for each bowl. ( unfortunately, i ran out of blue colour, so i used 6)

Mix well. DONT use the same spoon for all the bowls...

Pour 1 bowl at a time, into the baking dish, spreading CAREFULLY to the edge of the dish. Make sure not to mix-up the colours.

Place in the oven. Bake for about 1& a half hours or until a wooden pick inserted in the middle, comes out clean.

Cool completely on wire rack. Make sure the cake is COMPLETELY COOL before spreading the icing.

For the Icing:

In a large bowl, cream margarine & shortening till light & fluffy. Add vanilla, icing sugar & milk. Mix well. (U can add a tablespoon more of milk to make it the consistency u require.)
