Tasty treats: Easy Rainbow Cupcakes Recipe

My parents often remind me of how I used to make purple pastry for my dad to eat when he got in from work, something he for some reason wasn’t super keen on and had to get rather inventive about why he couldn’t eat my baked delights straight away - as such I’m really keen that any food my kids make has to taste good enough that I can eat it with a real smile on my face and not a forced grin. Despite the unusual colour, these rainbow cakes totally deliver, being moist and tasty as well as super cute.


For the cakes –
110g Margarine or butter
110g Caster sugar
110g Self raising flour
2 Eggs
Green food colouring
1 tsp Vanilla extract
2 tbsp Milk

For the decorations –
75g Butter
14g Icing sugar
Rainbow sweets

Kate's son and daughter mixing cake mixture in a bowl

To make the cakes mix the margarine and sugar together then add the self-raising flour, eggs, vanilla extract and finally the milk, then add your food colouring - add a bit at a time until the cake mixture looks a grass like colour. We at first tried using one of the gel food colourings but the colour it created looked really brown and so we returned to using our normal liquid food colouring instead.

Divide you cake mix into 12 cupcake cases in a cake tray and pop in the oven for 8-10 minutes. If your children are anything like mine they will devote this time accordingly to ensuring that the bowl and any spoons have no cake mixture left on them, my youngest looking remarkably like the Hulk by the time I managed to get the bowl back.

Because the cakes are meant to represent the land on which the rainbow is on, you want to make sure your cakes are green (nice fresh grass) and not brown (muddy old field) so try and get them out of the oven before they brown. I took mine out as soon as they looked like they had risen enough and checked that they were cooked by popping a clean knife in them. If the knife comes out clean they are done, if it’s messy they need another minute or so.

Leave your cakes to cool while you make the buttercream for your clouds, mixing together the icing sugar and butter. We used an electric hand whisk for this as both my kids claimed it was far too hard on their arms otherwise! Using teaspoons put two small ‘clouds’ onto your cakes and then cut the rainbow sweets to size and add these, pushing one end of each rainbow into each cloud to get your rainbow to stand it up. And you’re done! All you need to do now is munch your rainbow cakes to give you a bit of energy before you race around looking for that elusive pot of gold.

We hope you enjoy making (and eating) your cupcakes as much as we did - honestly, they never last long in our house!
