Taiwanese Castella Cake
Description
This Taiwanese Castella Cake begins with sifting cake flour and combining it with warm avocado oil, cold milk, and vanilla extract to create a smooth batter. Egg yolks are added, providing richness, while the egg whites are whipped with cream of tartar and sugar to soft peaks, giving the cake its characteristic lightness.
The egg whites are carefully folded into the yolk batter to maintain airiness. The batter is poured into a parchment-lined round cake pan and baked at a low temperature, producing a spongy cake with a tender crumb and minimal browning.
The gentle baking method and use of avocado oil keep the cake moist and flavor subtle. This cake is enjoyed plain or with minimal accompaniment, highlighting its airy texture and mild sweetness.

- 50 ml milk cold, whole

Prep:
- Preheat oven to 250°F/121°C.
- Line a piece of parchment paper at the bottom of the 6" round cake pan.
- Separate the egg whites from egg yolks (while cold).
Make the egg yolk batter:
- Sift cake flour into a medium mixing bowl. Set aside.
- Pour 30ml oil in a small pot and heat until the oil reaches 75°-80°C.
- Add the flour mixture into the hot oil and mix well with a spatula.
- Pour cold milk and vanilla extract into the flour mixture to reduce the temperature and mix well.
- Add all the egg yolks in at once, and mix until very smooth. Set aside.
Whip the egg whites:
- Place the egg whites in a stand mixer fitted with whisk attachment.
- Whip egg whites, and add in cream of tartar when it becomes foamy.
- Gradually add in sugar and whip until soft peaks.
Combine the mixtures:
- Fold in egg whites into the yolk flour mixture in 3 batches, until well combined with no white streaks.
- Pour cake batter at a height of 8-10" to break any air bubbles, and into the baking pan/baking tray.
- Tap the pan a few times on the counter to release any remaining bubbles.
- Place cake pan into an aluminum foil dish/baking pan and place into a roasting pan in the centre of the oven.
- Pour in body temperature tap water (35°C) into the roasting pan to ½" deep.
Bake:
- Bake the castella cake at 250°F/121°C for 60 minutes.
- Increase the oven temperature to 300°F/149°C and bake for an additional 15 minutes.
- Test for doneness by gently tapping on the cake with a silicone spatula. If it feels springy, it is done. If not, extend the time for 5 more minutes.
- Turn off heat.
- Remove water bath and leave cake in the oven for another 5 minutes to dry up.
- Take the cake out of the oven and cool on a wire rack for 10 minutes.
- Give the cake a good tap around the edges to loosen.
- Remove bottom from the pan and cool completely on a rack.
- Cover and chill the cake or slice and serve.
