Psychedelic Rainbow Swirl Lollipop Cake

Woaaah. This cake is a bit of an attack on the eyeballs isn't it? But I love it so much. I think this may be my favourite cake that I've made this year. Yes, even more than the Pocky Cake. Last week was Regex Man's birthday, and in case you don't remember, he has been the recipient of some of my craziest cakes; the Mint Chocolate Chip Cake, the Rainbow Cake with jelly beans and the Fudge Brownie Cookie Dough Cake, just to name a few. He was also the inspiration behind my beloved Fruit Tingle Cake i.e. pretty much the best icing I have ever made. He has a sweet tooth that rivals my own, and I always feel like I can go super over the top on his cakes and he'll love it.But this year I was completely out of ideas. I've been in a creative baking rut for a while now, and I keep having to force myself out of it. I looked to the internets for inspiration in my time of need. I came across this visually stunning but seriously simple decorating technique from Hungry Happenings and immediately loved it. I decided it would be a perfect idea for this cake since last year I put a rainbow inside the cake, and this time I would put a rainbow on the outside. I'm also a big fan of Katherine Sabbath (if you're not following her on instagram, you should be) and remembered her gorgeous lollipop-covered cake and realised that rainbow lollipops would be the perfect topper for this particular cake. This cake is exactly the type kind of cake I like to bake because it's so impressive looking but is actually relatively straight-forward to make. And there's rainbows and lollies and popping candy. I love how the swirling icing matches the lollipops so that it kinda looks like the lollipops are melting all over the cake.I simplified the swirling rainbow decoration on the top of the cake by using royal icing instead of white chocolate ganache. It was less work, quicker to set and I think it helps ensure a brighter colour since you're working with a bright white icing as the base rather than a semi-translucent white chocolate ganache. I definitely suggest using gel colouring if you want to achieve the same brightness of colours in your royal icing. No innards shot of the cake, but it was fairly simple; a vanilla layer cake with Fruit Tingle Icing in between the layers and vanilla icing on the outside. Just so you know, I sat and ate the whole of that huge lollipop at the back while watching the Lego Movie. It was pretty great.Psychedelic Rainbow Swirl Lollipop Cake(makes a tall 3-layer 6" cake or a shorter 7" cake, icing idea adapted from this recipe)For the cake:expand_more
