When you add chocolate in your bakes, everything becomes different, this simple chocolate castella cake is prepared using a very simple batter then chocolate chips are added to take everything to the moon. This cake will be your new favourite. Start by preparing an 8-inch square cake tin by buttering the pan then lining it with a parchment paper. Preheat your oven to 175 degrees Celcius then start by breaking 8 eggs then separating the yolks from the whites and place the whites in a large bowl.

In another bowl, sift in cake flour together with unsweetened cocoa powder and cornstarch, sifting will ensure your cake comes out soft from the oven and the addition of cornstarch will help to reduce gluten. In a small bowl, add corn oil heat the oil in a microwave for about a minute and thirty seconds then pour it into the dry ingredients mixture and using a whisk, start mixing them immediately until very smooth. Add in 50% dark chocolate chips and continue to stir gently for about three minutes until they are melted.

Add in milk and stir it in, at first it will be hard to mix but as you continue, everything will come together. Once everything has come together, add in the 8 egg yolks and mix in well in the cholate mixture and when the mixture thickens, add milk according to flour absorbed, different cocoa powder brands have a large water absorption so you may need to add milk until you have a very smooth and silky chocolate batter. You can add about 10 ml of milk each time while mixing until you achieved the desired consistency.

For the egg whites in that you saved in the first bowl, add in about 4 ml of lemon juice and salt then beat the whites, halfway through, add 110 grams of sugar then continue beating the whites until it reaches a soft peak. Start folding the egg whites to the chocolate batter using a spatula and mix then slowly from the bottom up. Slowly fold them until they form a homogenous mixture, remember to be gentle with folding so you don’t force air out of the batter because this will create a hard cake.

Once finished, add in chocolate chips and fold then in then pour the batter into the prepared 8-inch cake tin and top with more chocolate chips. You will need a rectangle baking pan then place the 8-inch baking tin with the batter in and add about 70 degrees of warm water to the outer baking tray.

Bake the cake at 330 degrees Fahrenheit for about 65 minutes. Use a skewer to check if the cake is fully baked before removing from the oven, if not, leave it for another 5 to 10 minutes while checking it. Once out of the oven, let the cake cool before removing it from the pan then serving it. This chocolate castella cake is super moist, flavorful, and can be enjoyed anytime, best served with a cup of tea.
