Charcoal Marbled Rice Flour Chiffon Cupakes

I have a packet of charcoal powder which do not know what to use, so decided to try it in this rice flour chiffon cupcake recipes since I need to bake as give-away.

For Cake  

Ingredients : for 18-20 chiffon cupcakes cases base about 5-6cm
5 egg yolks
10g caster sugar
40g corn or sunflower oil  
1/8 tsp salt

70g milk
60g cake flour
5g  charcoal powder
1 tbsp vanilla extract

5 egg whites
45g caster sugar
1 tsp lemon juice or vinegar (I only used 1/4 to 1/2)

Method :
1. Sift cake flour and rice flour twice.

2. Mix egg yolks and sugar in a bowl, whisk till sugar has dissolved.
3. Add in oil, salt, milk, vanilla exract and mix well.
4. Sift in flour mixture and whisk well.
5.In another bowl, beat the egg whites and lemon juice/vinegar till frothy. Add in sugar gradually and beat until approaching stiff peaks (meringue stand straight with a little curve at the tip) or till stiff peaks (this stage is a bit difficult to fold with egg yolk mixture). 

6. Use whisk to loosen the egg yolk batter a bit, then take 1/3 of meringue and use a hand whisk to mix well with egg yolk batter.

7. Fold in 1/2 of meringue and use a silicone spatula, gently fold with egg yolk batter till slightly combined. Fold in the balance meringue and gently fold till well combined.
8. Pour 1/3 of the batter to another bowl, mix in the 5g charcoal powder and gently fold till well combined.
9. Scoop ratio 2:1 vanilla mixture vs charcoal mixture into cupcake cases and use a satay stick to whirl the batter.

10. Bake at pre-heated oven at 160C at center rack for 20-25 mins.

11. Knock the cupcake on table top once and set aside to cool completely.

For Vanilla Custard Cream Filling

Ingredients  :

150g dairy whipping cream

3 tsp custard powder 

1 tsp homemade vanilla extract

2 tbsp icing sugar

* this amount of cream is just nice with little left over as my cupcakes are full of cream. 

Method :

1. Whisk whipping cream, vanilla extract, custard powder and icing sugar till peak form (not too stiff) under a bowl of ice water. Pls ensure not to over beat the cream.

2. Chill the vanilla custard cream in the fridge for at least 15 mins to let it set a bit. I put in the freezer to fasten the process.

Assemble :  

1. Insert the long narrow pipping tip into the center of the cupcakes and squeeze the whipped cream in (I like the generous of cream so I just press as much as I can, until the cake fluff up lol).

2. Sprinkle with snow sugar and garnish with fruits if desire.

3. Serve cold!

Verdict?
The cupcakes just tasted like vanilla cake, the charcoal powder just only created the visual effect without any taste.
