Magic custard cake, one cake batter turns into 3 layers dessert!
The first bottom layer is a dense gooey cake, then the second layer is a creamy custard and the top layer is a sponge cake.. All made up of ONE batter! Oh yeah, that’s the magic part.
I decided to flavour this magic custard cake into a taro or purple yam flavour. My favourite bubble milk tea flavour if you’re familiar with this (seriously has become a stereotype) asian drink. But yeah… I got to be honest, there are no actually purple yam in this taro magic custard cake. More on that later.
Anyway, I also want to flavour it in a different way other than vanilla and chocolate. So…
Ok let’s get started, shall we?
The ingredients are:
Yep. Taro tea powder.
Umm… But what’s that?
It is a drink mix powder, often found sweetened and sometimes called taro latte powder if it consist some milk on it where you can just dilute it in some warm water/milk, put some boba pearls and ice and you got boba taro milk tea!
Also another reason why I decided to make it into taro flavoured magic custard cake is that.. Well, Let’s start from the beginning. The first magic custard cake recipe I encountered and made me realise such awesome dessert exist was a chocolate one then I found the vanilla and even fruit flavoured ones. Then I found the matcha and I was super intrigue to make the matcha flavoured magic custard cake until one day I decided to use all of my matcha powder for a birthday cake for a friend. So… Scratch that because I don’t have the money to buy another packet of high quality green tea powder.
After some times, I’ve forgotten this magic custard cake idea until I found some packets of taro tea powder stored deep inside my pantry. As I’ve said before, being a boba taro milk tea lover (fanatics, even.), I’ve tried to made them my own and totally forget them after using a few packets and consuming them every. Single. Day.
So, as I’ve said before, this cake got no actual purple yam on it instead it’s the flavouring powder. I mean.. Let’s face it, in most countries, finding taro tea powder is way easier than the actual taro itself.. You can just purchase it online!
Well, I found mine online too, but unfortunately this shop did not ship worldwide. Maybe you can find it in your asian grocery stores? If not, still. Buying it online is your best chance. The taro tea powder that I own is not that great in terms of quality anyway. The colour was a bit off.
Whip the egg whites on high speed until it becomes fluffy like a cloud. Stiff peak stage.
Put the clouds into the purple liquid.
You’re not suppose to loose a lot of air in the whipped egg whites, but folding the whipped whites to the liquid batter is damn hard.
So here’s what I did, I whisk them gently together, just whisking from the side ( not from the center), turning the bowl as I whisk and once I saw the whites are pretty much covered with the purple, I’m done. It won’t and shouldn’t be totally mixed together so don’t stress out and vigorously whisk them.
Wait, although I should tell you to let it cool first, if possible, put it into the fridge for an hour or so until the cake feels firm, then you can cut it. If not, this cake would be pretty messy to cut.
Although, for me, the cake taste better in room temperature because the custard part goes even creamier. But yeah, it’s a personal preference and plus, if you’re not a big fan of waiting, you can just dig in!
Well honestly, I’m not the biggest fan of waiting too, especially with food. But since I took quite sometime taking pictures of this taro magic custard cake, it comes to temperature as time goes by…..
So here’s the best chronology to enjoy the taro magic custard cake:
Bake – let cool – sprinkle with icing sugar – cut into pieces – wait until the cake has come to room temperature – best part, DIG IN!!
Taro magic custard cake recipe
Makes 1 pan of 21 x 21 cm cake
• 4 eggs (yolks and whites separated)
• 225 g white sugar
• 60 g all-purpose flour
• 15 g taro tea powder*
• ½ teaspoon salt
• 110 g unsalted butter (melted)
• 475 ml (2 cups) whole milk
• vanilla extract (optional)
* Unsweetened, if you cannot find the unsweetened kind, use 200 g sugar or adjust accordingly. Also, 15 g is based on my not-so-stong taro powder, if you can find a better quality, use about 7-10g or adjust to your liking.
How to make it:
1) Whip the egg whites with 2 tablespoon of the sugar until stiff peak stage. Set aside.
2) Whip the egg yolks with the rest of the sugar until pale and fluffy then add in the flour, salt and taro powder, whisk until combined.
3) Pour in the melted butter, stir, then pour the milk and vanilla, stir until just combined.
4) Working half at a time of the egg whites, spoon and whisk them together, just by the side GENTLY trying not to loose a lot of air, the mixture will not be totally incorporated.
5) In a 21x21cm square pan that has been buttered, line the sides of it making the parchment paper hang on to the sides then coat with caster sugar, pour in the batter then bake at a preheated oven at 180°C or 360°F for 50-60 minutes.
6) Let the cake totally cooled before unmolding it, sprinkled with icing sugar then cut into pieces.
