Banana Walnut Chiffon Cake

The recipe original from All That Matters, but I first saw it from Bakericious. I added chopped walnut to the cake. My chiffon is actually could be higher, however it fell from the tube while cooling inverted. The cake is still fluffy, soft and moist, and it has really strong banana fragrance even without putting any essence.

Ingredients :

(A)
4 egg yolks
40g castor sugar
1/4 tsp salt
50g oil
150g mashed bananas

(B)
120g Cake flour
1/2 tbsp Baking powder
1/8 tsp Baking soda

(C)
4 egg whites
40g castor sugar
1/2 tsp Cream of Tartar

40g Toasted Walnut, chopped (optional)

Method :
- In a bowl, using hand whisk, whisk yolks and sugar till sugar dissolves.
- Add oil and salt, whisk and add mashed bananas. Stir well.
- Fold in sifted flour and mix well.
- Preheat the oven at 170C.
- In another bowl, using an electric mixer, beat till the whites are frothy. Add in Cream of Tartar and beat till soft peaks.
- Add in sugar gradually and beat till stiff peaks.
- Fold in 1/3 of the whites into the yolk mixture using a rubber spatula (I usually used hand whisk) till incorporated.
- Pour the mixture to the remaining egg whites and fold in gently till incorporated.
- Add chopped walnut, mix well.
- Pour the batter into chiffon tube pan.
- Bake at 170C for 40 mins.
- Insert a skewer to check if cake is done.
- Remove from the oven and invert the pan. Remove the cake from pan when it's completely cooled. The surface will feel abit wet but it will be dry after exposing to the air.
