Soft Cake Base

Ingredients

Cake Base

4 eggs (about 55g each)

1/4cup(45g) vegetable oil 

1/4 cup(45g) milk 

1/2cup(55g) cake flour 

1/4cup(40g) granulated sugar 

1tbsp (5g) lemon juice 

1tbsp (5g) vanilla extract 

Notes: By cake flour, I mean low protein flour, which normally contains 7-9% protein (Mine is around 8%). Not self-rising flour.

Steps:

1. In a clean bowl, mix well vegetable oil and milk. Add in cake flour and mix well. Separate the eggs. Add the egg yolks into the batter and mix well. Set aside.
2. Line the baking tray (28*28*2.6cm) with parchment paper or baking mat. Preheat the oven to 150℃(302℉).
3. Add sugar, lemon juice and vanilla extract into the egg white. Use a hand mixer to beat until soft peaks form. Take a scoop of whipped egg white and gently fold it in the batter until just combined. Pour all the batter into the whipped egg white and gently fold it in until just combined. Pour all the batter into the baking tray, smooth it out and give it a tap or two. Send into the oven to bake for 30 minutes or until golden brown.
4. Take the cake out of the oven and let the cake cool down on the cooling rack before take it out of the cake pan. When the cake is cool to touch, release the sides of the cake with an icing spatula, turn the whole cake pan upside down on the parchment paper. Take off the pan, and peel off the baking mat.
