I have ranted long enough about the tediousness of making rainbow cakes. Usually when people order them, my heart would sink and I would be like “ Oh no not again!!” Why rainbow why why why! Firstly, you need a lot of bowls to contain different color batter. Secondly, washing up after is a chore and thirdly, which I secretly think that’s the reason why I hate making them is because I don’t get to enjoy the fruits of my labor!! I don’t get to admire the pretty slice of rainbow cake that only happens after people cut the cake!
Well, that’s just from the baker’s perspective. I guess the joy of the recipient is enough to put a smile on my face. And that to me is self-satisfying. To celebrate this joyous season that is approaching, I decided to make a rainbow log cake. Christmas is all about red white green, actually all things colorful. So what better occasion to surprise someone than to make this gorgeous cake. It's actually quite simple to whip up. I have a diagram below to show you where each color batter should be poured into the Swiss roll pan. Don't fret if some colors sip into the next color. A mix of colors would nevertheless turn out pretty as well!
