HOW TO MAKE FLUFFY CHOCOLATE SPONGE CAKE?

The look of this cake is what attracts me the most. The freshly crushed dark chocolate chips create a beautiful effect with shades of brown popping in every slice. When baked this cake feels just like spring, its super soft like cotton and so yum in every bite. The high amount of egg whites in this batter is the reason for its beautiful texture 

I’m sure when baked, not just the kids but everyone biting into it will call you a cake genius. It’s the cake texture which people truly love !! 

WHAT YOU NEED TO KNOW WHILE PLAYING WITH CHOCOLATE CHIPS TO GET THE GRAINY LOOK

Freshly ground chocolate chips are one of the main ingredients in this cake. However, to get the right texture you need to make sure the chocolate chips do not melt but remain grainy in texture. To make sure this happens, weigh the chocolate chips and refrigerate for 2 hours, this will avoid the chips from melting. Then grind this into a powder (not superfine thou). Let the chocolate chip powder sit in the fridge until you plan to use it in the batter

When the cake batter is completely ready, that’s when you fold in the cold chocolate chip powder into the mixture. Once mixed, immediately bake the cake.  

The reason we follow this process is to make sure the chocolate chips do not melt but remain grainy throughout the process. We do not want a marbled chocolate effect but a grainy look to the cake thus the detailing to this part. You can even use milk chocolate chips if you’d like to or maybe just grind some chopped chocolate bars instead of chips.

CAKE PAN FOR JAPANESE COTTON CAKE or Chocolate Chip Cotton Cake

This cake is just like the chiffon cake

For any regular cake, we add some butter or oil (fat) to the dish and dust it with flour or just push in some parchment paper after greasing the sides of the dish. 

While making this cake, use whatever baking dish you’d like. Some recipes stress on using a tube pan while making chiffon cake or cotton cakes however you can use any baking dish lined with parchment paper only on the bottom of the dish and not on the sides. The reason we do so is to make the cake cling to the sides of the baking dish while in the oven. This will allow the cake to rise high. Do not add any fat (oil or butter) to the baking dish for greasing purposes. 

All you need to do is put a piece of parchment paper at the base of the baking dish and not for the sides 

Chocolate Chip Cotton Cake Once Baked

Once the cake is well baked, take it out of the oven and turn the baking dish upside down onto a wire rack. Further, let the cake remain in this position till it comes to room temperature. We do this to make sure it does not sink to the base of the baking dish or shrink while cooling. 

When the cake comes to room temperature run a knife through the sides of the dish and unmold carefully. 

Easy Chocolate Chip Cake Recipe

Ingredients 

3/4 cup (120 grams) dark chocolate chips (ground into a powder)

7 egg yolks

5 tablespoon (75 ml) Oil, unflavored

1/4 cup (65 grams) castor sugar

1 cup (120 grams) Self-raising flour

7 egg whites

1/4 teaspoon cream of tartar

1/2 cup (140 grams) castor sugar

Method 

Making the Dark chocolate chips powder:

Chill the dark chocolate chips for 2 hours in the fridge, then grind it to form a grainy texture. Let this chocolate chip grainy powder sit in the fridge until you add it to the batter before baking

Making the Batter: 

In a bowl, mix the egg yolks and the 65 grams castor sugar together

Once mixed, add the oil. Mix well until all the sugar has dissolved and the mixture seems creamy

Fold in the self-raising flour making sure there are no lumps. Once done, set this mixture aside

Beating the Egg whites: 

In another bowl roughly beat the egg whites. Add the cream of tartar and continue beating till it reaches soft peaks. At this point keep adding the 140 grams of sugar a little at a time and beat well until all the sugar is well dissolved and forms really stiff peaks

Now, using a spatula combine the stiff egg whites with the egg yolk & flour mixture. Fold in the egg whites using a spatula carefully. Do not over mix this mixture

Now add the chilled ground dark chocolate chip powder and roughly mix. Again, do not over mix, all you need to do is make sure the chocolate chip grains are all around the batter.

Baking the cake:

Once well-combined transfer the mixture in a 9-inch baking dish lined with parchment paper at the base making sure it is not greased with butter or oil. Do not put parchment on the sides of the baking dish

Tap the baking dish before baking to remove excess air bubbles from this mixture

Once ready, bake in a preheated oven at 170 degrees C for 50-60 mins. The cake should spring back when pressed in the center. That’s when you know it is well baked

After baking, let the cake cool upside down on a wire rack until it comes to room temperature. Pass a knife through the sides of the baking dish and unmold the cake

Note (chocolate chips tips)

Chilling the chocolate chips powder avoids it from melting while combining it with the cake batter. Once you add the chilled chocolate chip powder to the batter bake the cake immediately. This will make sure your cake has a grainy look and not a marbled chocolate look which normally happens if the chocolate chips melt while mixing it in the batter.
