easy rainbow cake recipe

if you are subscribed to my youtube channel you might of seen my "rainbow cake" video that i posted.
so my cake didn't end up looking as good as the beautiful, vibrant pictures that you find on pintrest, but it tasted AMAZING!

i am going to share with you my recipe and method in the most easiest way a can so anybody can give this ago!

ingredients for the sponge:

• 125 grams of soft butter
• 225 grams of self raising flower
• 150 grams of caster sugar
• 3 eggs
• 1 tea tablespoon of baking powder (or less)
• a pinch of salt
• a drop of vanilla extract
• a few colours of gel food colouring (its more vibrant if you use gel)

ingredients for butter icing 
i don't use measurements for this. i just keep adding and mixing, with a little bit of tasting until i decide its perfect!

• room temperature butter
• dash of milk
• icing sugar

method:

• pre heat the over to gas mark 5 or 190c or 375f
• put all the sponge mixture in to a bowel but not the food colouring!
• use an electric mixer or do what i did and use a hand held bender to mix all the ingredients together until it forms a creamy mixture

• depending on how many colours you are using, split the mixture equally into bowels. i used four colours so i only used four bowels. 
• once the mixture is evenly split, start adding your food colouring, for example: put blue in one bowel, pink in another and so on...

• if you have more than one cake tin lucky you! i only had one cake tin the same size so i had to cook four sponges separately!
• grease the tin well by using butter
• add your first coloured mix to the tin (or if you have more than one tin, put a colour in each tin)
• put your sponge/sponges in the oven to cook. 
• i didn't go by a time whilst cooking my sponges because im an idiot and never found out how long you keep them in an oven for! i would say check after about ten minutes to see how they are getting on. prick it with a fork and if the mixture does not stick it should be ready. of course make sure it is spongy before taking it out of the oven.
• whilst the sponge/sponges are cooking start making the butter icing!
• put in a few spoonfuls of butter into a bowel, with a drop of milk and icing sugar
• mix until smooth and creamy

• leave the delicious butter icing to one side until the sponges are cooked
• once the sponges are cooked place them on a cooling rack to cool down.
• do not attempt to put the butter icing on the sponges whilst they are warm otherwise it will melt and make your cake soggy!
• next we are going to want to build the cake together
• stick the sponges together using a thin layer or butter icing. if you like you could also add a layer of jam

• next cover your cake it the rest of your butter icing! 
• you may want to add decorations or sprinkles but i left my plain.

i hope i have explained everything in an easy way and it is learning difficulty friendly!
