- 2 bags Skittles sweets

Method
- For the cake, preheat your oven to 180°C / gas mark 6 and grease your two 20cm cake tins, lining the bases with greaseproof paper.
- In a large bowl, beat the sugar and Stork together. You can then add your eggs in one at a time until fully combined.
- Gently fold in the self-raising flour, before adding in 4 tablespoons of milk.
- Bake on the middle shelf of the oven for around 40 minutes – the sponge should be golden and springy to the touch.
- Allow to cool for a few minutes in the tins, then turn out on to a wire rack where it can cool completely.
- For the buttercream, while your rainbow birthday cake sponges are cooling, get a bowl and beat together 100g Stork and 140g icing sugar until smooth.
- Use your palette knife to spread jam on the bottom sponge, followed by a layer of buttercream. Then, sandwich your two cakes together.
- Place back on to the wire rack, with a tray underneath, and start preparing your decoration.
- For the decoration, pick out 8 white Haribo marshmallows and tear them into chunks. Set them to one side as these will make the clouds.
- Place all the remaining white marshmallows from both Haribo Chamallows packets into a saucepan.
- Add 100ml of milk to the marshmallows and place on a very low heat, stirring continuously until fully melted.
- Let it cool slightly, then pour the warm mallow mixture over the top and sides of your cake. Leave to set for 30 minutes.
- Once set, add your skittles on top in a rainbow design and cluster the cut-up marshmallow pieces at each end to create clouds. Ta-dah!
