I am surprised why it took me so long to include a chocolate version of Swiss roll recipe in this blog. So here it is; a simple recipe with just whipped non-dairy cream as filling. Tasters approved. I used 4 eggs ingredients to baked in an 11 x 9 inches pan for the cake shown here.
Ingredients:-
4 egg yolks
1/2 tsp vanilla extract
25g Oil
45g milk
45g Cake flour + 20g cocoa powder
Pinch of salt
20g castor sugar
4 Egg whites
40g Castor Sugar
Method:
Mix egg yolks, oil, sugar and milk together and whisk until blended. Sift flour and cocoa powder together with salt and mix into the yolk batter until smooth. Set aside.
Beat the egg whites till foamy, add in sugar gradually and beat till stiff peak. You may add a pinch of cream of tartar to whip the meringue if you wish.
Add 1/3 meringue into the yolk mixture, stir with a hand whisk until batter is lightened then add 1/3 more of meringue and continue to fold until combined.
Add the final portion then switch to spatula to fold gently until batter is smooth and no streaks can be seen. Pour into prepared pan (I used 9″x 11″ pan); smooth out the top by shaking the pan from side to side. Give it a few tabs on the table top to remove big bubbles. Bake in preheated oven on the rack above the centre rack, at 180C for 10mins, then switch the tray inside out and continue baking another 3-4 mins or until golden brown.
Remove the cake and immediately invert on a rack lined with a clean piece of parchment paper. Peel off paper lining and leave it to cool on a clean piece of parchment paper on a cooling rack.
Once cooled, apply whipped cream and roll up. Chill well before slicing and serve.
