Rainbow cupcakes are one of my favourite types of cupcake to make, they take a bit more time to prepare but they look so cute once baked that the extra effort is worth it.
You will need :
- 4oz Caster Sugar
- 4oz Butter (preferably 'Stork' baking butter)
- 4oz Self Raising Flour
- 2 Medium Eggs
- 1tsp Vanilla Extract
- 1tbsp Milk
- Red, blue, green and yellow food colouring
To make the cakes :
- Preheat the oven at 180C/350F/Gas Mark 4.
- Line a muffin tray with cupcake cases.
- Cream together the butter and caster sugar until pale and fluffy.
- Beat the 2 eggs into a measuring jug and pour the eggs into the butter/sugar mixture a small amount at a time - make sure the egg is fully beaten in each time you pour it.
- Stir in the vanilla extract.
- Use a sieve to cover the mixture with the flour.
- Once the flour is in use a large metal spoon to carefully fold flour into the mixture, once the mixture has started to stick add the tbsp of milk.
- Keep folding the mixture until smooth
- Divide the mixture into 4 tubs
- Add food colouring to each of the tubs of mixture, adding enough colouring to make it a vibrant colour.
- Place a single colour in each of the cupcake cases, then add the next colour on top of the previous colour and again with the next two colours until you have 4 layers of colours in each case. Alternatively use a piping set filled with the different mixtures and pipe the colours in - this works slightly easier when layering.
- Bake in the oven for 15 minutes, test with a cocktail stick, if it comes out clean they are done!
- Leave them to rest in the tin for 10 minutes while they cool then transfer to a cooling rack.
For the icing you can use a variety of different techniques, the one pictured above is a simple buttercream and the rainbow on top was made using a knife to cut out the centre of the cupcake - the same way as the butterfly cupcakes are made.
Adding a colour to the buttercream different to the colours already in the cake and placing some cute edible decorations on top looks cute when removed from their cases.
Using a piping set with the buttercream to completely cover the top of the cakes gives people a little surprise when it comes to peeling the case off to reveal the hidden rainbows.
For the buttercream you will need :
- 5oz Butter
- 10oz Icing Sugar
- Caster Sugar (Usually 10oz but add to your taste)
To make the buttercream :
- Beat the butter until soft.
- Add the icing sugar and carefully fold it in mixing carefully.
- If the mixture is a bit dry add a small dash of milk.
- Finally add the caster sugar, the more you add the sweeter and more textured it will be. Add any left over food colouring if you would like a coloured topping.
