TAKEAWAYS
I had a few bananas left and have been using them for dessert throughout the week. Made banana chiffon cake this time~ It’s my first time making chiffon cake and used a wet ingredient banana on top of normal chiffon cake ingredients. Cake was very soft and fluff, but inside was more wet than I expected and not as spongy. I summarized a few points that might lead to such results here:
- wet ingredients to dry ingredients ratio might need to readjust, so banana will not add too much extra moisture
- quickly mix egg white in cake mix, not losing air bubbles
- bake cake for long enough that the surface is yellow/brown enough. I worried about overbaking/burning the cake, so I took out around the suggested 50-60mins, but I have almost twice the weight of all ingredients, so should have taken longer time. Wait next time!
RECIPE
Ingredients:
- 50g banana
- 1/2 lemon juice for flour mixture, another 1/2 for egg white
- 35ml oil
- 1 whole egg
- 3 eggs with egg yolk and egg white separated
- 50g cake flour
- 1/8 tsp salt
- 50g sugar
Step 1: Mix banana (50g), 1/2 lemon juice, 35ml oil
- smash banana; I had 123g banana, so I adjusted oil and egg accordingly, noted as below
- + 1/2 lime juice
- ** adjustment ** + 70ml oil (I did NOT know chiffon cake uses so much oil….)
- blend in and mix well

Step 2: Add a whole egg, mix well; then add in 3 egg yolks one by one
- **adjustment** I added 5 egg yolks

add egg yolk in 1 by 1 
Step 3: Mix in 50g cake flour, 1/8 cake flour
- ** adjustment** used 100g cake flour, 1/4 tsp salt

Step 4: Add 1/2 lemon juice to egg white, whisk till firm (tips not falling)
- add sugar in 3 separate times

Step 5: Mix 1/3 egg white into cake mix, put them back into the leftover 2/3 egg white, mix well
- be quick and mix well by flipping, otherwise will lose air bubbles, which might be my case?

mix well 
add back to 2/3 egg white
Step 6: Bake at 140C/280F for 50-60mins
- pour cake mix into cake mold, drop to get air bubbles out
- place cake mold into a pan filled with hot water (do not need too much water)
- **Bake till surface turns yellow/brown** If takes out before browned, might not be cooked through; inside is still wet! DO NOT worry about overburnt next time!
