We think this is every child dream to have a rainbow cake for their birthday (and not only). We decided to make this dream come true for our inner child and we encourage you to do the same!

Ingredients for rainbow cake:

For dough:

  • 230 g butter
  • 220 g fine sugar for baking
  • 5 egg whites
  • 2 tsp of vanilla extract
  • 370 g of wheat flour
  • 4 tsp of baking powder
  • half a tsp of salt
  • 350 ml of milk
  • 5 colours of dyes (purple, blue, red, orange and yellow) – use gel or powder dyes

For cream of whipped cream and mascarpone:

  • 900 ml or 1000g of cream (30 or 36%), chilled
  • 250 g mascarpone cheese, chilled
  • a few tablespoons of powdered sugar, to taste
  • vanilla or lemon extract



  1. All ingredients should be at room temperature.
  2. Flour, baking powder, salt – sift, put away.
  3. Put butter and sugar in a mixing bowl and mix it into a smooth, fluffy mass. Pour the egg whites one after the other and mix then add the vanilla extract.
  4. Add the milk and dry ingredients to the mixed butter mass, stirring with a kitchen spatula or a spatula only until the ingredients are combined.
  5. Divide the dough into 5 portions and place each part of the dough in a separate bowl (in our case the parts were around 200g each). Add dyes: purple, blue, red, orange and yellow. Mix thoroughly with the dough to obtain a uniform color.
  6. Put the dough into 5 molds (cake tops or disposable aluminum molds) with a diameter of 23 cm and bake for 15 – 20 minutes at 170 ° C or to the so-called – dry stick.
  7. Remove from the oven, cool.


  1. Cream, mascarpone cheese and powdered sugar put in a mixing bowl (all together) and beat to create a thick cream. At the very end of whipping, add the selected extract.


  1. Lay the individual cake tops with cream: place the violet top on the plate and spread with our made cream, then do the same with blue, red, orange and yellow cake tops.
  2. The tops and sides of the cake are also spread with cream.

The entire cake should be cooled in the refrigerator for a minimum of 3 hours.

And voila! Now it is up to you how you want to decorate your rainbow cake! Let your imagination go to work 🙂
