Ingredients

500g caster sugar

400g Asda Best for Baking Cakes

400g self-raising flour

1tsp baking powder

7 large eggs

2tbsp whole milk

2 of each Dr. Oetker Extra Strong Food Colour Gel in blue, green, yellow, orange and red

3 x 400g Asda Vanilla Flavour Frosting

Method

1
Preheat the oven to 200C/180C Fan/Gas 6. Grease and line 5 x 20cm round sandwich tins.
2
Put 400g of the sugar, the Best for Baking Cakes, flour and baking powder into a large bowl. Crack in 5 of the eggs and add the milk
3
Beat with an electric whisk until fluffy. Divide into 5 bowls. Add 1⁄2 tube of blue food gel to one, then repeat with the other colours. Mix gently until coloured evenly.
4
Spoon each batter into a separate cake tin and level the tops. Bake for 18-20 mins until a skewer inserted comes out clean. Cool fully on wire racks.
5
Meanwhile, reduce the oven to 140C/120C Fan/ Gas 2. Line 2 baking trays with baking paper.
6
Separate the remaining 2 eggs and put the whites in a large, clean bowl (save the yolks for another recipe). Beat with an electric whisk until soft peaks form. Beat in the remaining 100g sugar, a spoonful at a time, until incorporated, then beat on high until thick and glossy.
7
As shown in the images below, using a clean, wet paint brush, paint stripes of each colour of food gel up the inside of a large piping bag. Put the meringue in the bag. Cut off a 2cm hole at the end and pipe 18 meringue ‘kisses’ onto the trays. Bake for 30 mins then turn down to 120C/100C Fan/Gas 1 and bake for a further 45 mins. Leave to cool.
8
To assemble, sandwich the layers together with frosting, starting with the blue cake on the bottom, then green, yellow, orange and red. Coat the outside in a thin layer of frosting and chill for 30 mins.
9
Reserve some frosting for the top of the cake then divide the rest between 5 bowls. Use 1⁄2 tube of each food gel to colour each one. Divide into 5 piping bags then cut off each bag 2cm from the tip. Pipe a 2cm-deep line of each icing around the cake, starting with blue on the bottom.
10
Smooth with a cake scraper or palette knife.
11
Ice the top of the cake with the reserved frosting. Top with the meringues just before serving.
