 This post may contain affiliate links. Please read my privacy policy for more details

In this weeks video tutorial I’m creating quite a simple looking cake, but it’s packed with different techniques. This cake is perfect if you are looking to create your first drip cake, or maybe you’re looking to create Rainbow swirls on your cakes and cupcakes. In this tutorial I go through step by step how to add these techniques onto your cakes and also how to decorate your cake using pretty sprinkles. I mean who doesn’t love some sprinkles!

For this cake I’m using some of the pastel sprinkles by Happy Sprinkles which look amazing and if you want to try some of their many sprinkle mixes yourself there are details of how you can get 10% off all your sprinkles a little further down.

The perfect cake for beginners

I absolutely love how pretty this cake looks. Its quite simple in it’s design, but it can be made in any colour to match your theme, or to match your sprinkles and you can dress it up by adding toppers or names to really personalise it.

For the cake itself I baked 1 and a half times my normal vanilla sponge cake recipe. So instead of having 2 cakes I divide into 4 layers I had 3 cakes I divided into 6 layers. This gave me a slightly taller cake than normal as taller cakes seem to be so popular on Instagram recently. But you can make it in any size depending on how many people you need to feed. The cake was then covered in my vanilla buttercream which I coloured in a light pink using the Colour Mill rose. This pink matched the lighter pink in my sprinkles perfectly.

The perfect pastel sprinkles

One of the main parts of this cake were the sprinkles and ever since I saw the ‘Pastel Vibes’ mix by Happy Sprinkles I just knew I had to use them on a cake. They also have so many other amazing sprinkle mixes, so there will definitely be one to match your theme and colours.

I loved the Pastel Vibes sprinkles as it had such a mixtures of different colours and shapes. There are pastel strands hundreds and thousands, star and hearts, coloured chocolate and metallic balls and long metallic pink strands.

How to create a white drip for your cakes

I knew for this cake I wanted a drip that would really stand out against the pastel pink buttercream so in the tutorial you will see how I made this white drip. Because white chocolate always has a slightly yellow tone it’s hard to get your drip completely white without adding alot of white food gel. For this drip I actually used bright white candy melts. Candy melts are different to chocolate but they work the same when creating a ganache, so using a ratio of 1:1 candy melts to double cream I warmed up the double cream and added this to the candy melts until I had a nice smooth mixture. Because the cream is slightly off white I did add a teaspoon of Sugarflair’s superwhite powder just to brighten them up.

One tip I would always give is to allow your ganache mixture to cool before adding it onto your cake, and pop your cake in the fridge for a few minutes so the buttercream is cold. Also always practice your drip on a glass before adding it to your cake. You will see me to do in the tutorial.

Piping Buttercream Rainbow Swirls

I have to admit I am a massive fan of using more than one colour in a buttercream swirl. It just looks so pretty. But how do you get your buttercream into the piping bag so all the colours come out evenly?

If you haven’t seen my rainbow swirl tutorial you might not have seen that the best way to do this is to add all your colours onto a piece of cling film first. You can then wrap this in to a sausage shape and add this into your piping bag.

It is such an easy and relatively mess free way of doing it. You then get these pretty buttercream swirls which are great for the top of your cakes or to add onto your cupcakes. In the tutorial I go through step by step how to do it, plus what piping tip I use for this cake!
