Instagram Inspired Rainbow Cake with Gold Drip Tutorial

Earlier this week the Cakes by Lynz Instagram page reached 100k followers which is so amazing and I can’t quite believe we hit this milestone. Thank you so much to everyone who follows the page, likes the posts, comments and sends me messages. To celebrate I thought I would make an Instagram inspired cake for this weeks video tutorial.

So on this cake we have coloured buttercream on the outside, coloured to match the Instagram colours, some fun buttercream rainbow swirls on the top. A gold drip and I’m even going to be showing you how I coloured the cake on the inside too!

Colouring my rainbow sponge cake

For this cake I mixed up a batch of my vanilla sponge cake dividing it into 5 separate bowls. You can find the recipe for my vanilla sponge cake here! To colour your sponge you want to use gel colours, this allows you to add a small amount of colour but get rich vibrant shades. For my layers I used the colour splash gel colours and baked these as separate layers in my 5 inch round cake tins.

When the cakes come out of the oven you will see in the video they can look a little dull, due to the caramelisation on the outside. You want to level your cakes and trim around the edge to reveal these bright fun colours.

Some tips to stop too much caramelisation – I reduced the temperate I baked my cakes by 5 degrees Celsius, baking at 175 rather than 180. I also lines the sides of my cake tins with parchment paper.

The layers of sponge were then stacked together with some of my white American buttercream so that when the cake was cut you get these very separate colours.

Creating a gold drip for your cakes

For this cake I wanted to add a drip around the edge and the gold really compliments against the bright colours. To create the gold drip I started with the white Deco Melt by Fun Cakes. I find that this brand of candy melts when melted are super runny so make the perfect drip, without having to add anything else. If you are using a different brand of candy melts you may need to add a little double cream at a ration of 1:1 to thin it out.

In the tutorial you’ll see I melted down the Deco Melts in the microwave, and added some gold lustre dust. For this I used the glamorous gold lustre dust by Sweet Sticks. This doesn’t add any shimmer to your candymelts but it give it an ivory tone which is going to make it so easy to create the gold drip.

Creating a gold drip cake

If you’re creating a gold drip if you try and paint a white drip with gold, it can look really streaky and patchy. It is also really hard to paint right up to the edge without getting the paint on your cake. By colouring the candy melts and having that base colour you only need one layer of paint. Also if you miss any areas down the side, it doesn’t show. Take a look at the tutorial to see me paint the whole of the gold drip!

Rainbow Buttercream Swirls

The cake was finished off with some rainbow swirls of buttercream on the top to match the colour of the sponge cakes on the inside. This is such a fun technique to create and so easy to get those rainbow colours. Watch the tutorial to see how I use a sheet of cling film or plastic wrap to lay out the buttercream, before rolling it into a sausage to place into the piping bag.

For this cake I used the 2D piping nozzle to give fun ruffled swirls. One tip when creating your swirls, if you pipe the swirl but realise you need it a little closer to the previous one you can slide a small spatula underneath and just slide it across, giving you enough space to finish your swirls.

I really loved creating this cake and it meant so much to me creating a cake to celebrate the Cakes by Lynz Instagram page reaching 100k followers. I really never imagined it would grow so much when I uploaded my first Instagram post back in 2016. I am so grateful for all the support, comments, likes, shares and messages people send.
