  1. Preheat the oven to 170 degrees Celsius. Cream together the butter and sugar in a freestanding mixture until fully combined and fluffy. Add the eggs one by one and scrape down the sides of the bowl between each addition. Beat for 1-2 minutes until the mixture is smooth. In another bowl combine the flour, salt and baking powder, and mix until evenly distributed. Add the flour to the egg mixture in 3 separate parts. In another jug mix together the milk and the vanilla extract, then add to the mixture, beating on a slow speed. Divide the batter into 3 equal quantities, and colour each batch a different shade of pink using the gel food colouring. Line 3, 10cm round baking tins and add each batter separately to the three tins. Bake for 20-25 minutes until a skewer inserted into the middle of the cake comes out clean, allow to cool fully on a cooling rack.
  2. While the cake is cooling, make the buttercream. In the freestanding mixer, mix the butter on a high speed for 5 minutes. Then add the icing sugar in 3 separate parts and mix on a slow speed until fully incorporated. Add the milk and beat again on a high speed for a further 5 minutes.
  3. Add the water, rhubarb and sugar to a large saucepan and heat on a low heat until the rhubarb begins to break down and becomes like a compote in texture. Strain it thoroughly through a sieve and reserve the liquid that comes out. Set aside the rhubarb to cool.
  4. Assembling the cakes: Once the cakes are cooled, cut each one horizontally into 3 equal pieces. You should now have 3 round discs of cake in each colour, 9 total. Starting with the darkest coloured layer, pipe a ring of buttercream on the layer in a ring, leaving a space in the center. Put a teaspoon of the rhubarb into the space, then cover the cake with the medium pink layer and repeat until all 3 layers are assembled.
  5. Mix together the icing sugar with 1-2 teaspoons of the rhubarb cooking liquid until you have a very thick runny icing. It shouldn't be too thin or it will all run off the top. Drizze on top of each cake and allow to set slightly.
Recipe Notes
