Chocolate Cake

Ingredients

Directions

The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point. The book gives no cooking times either; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.

Prepare

  1. Preheat your oven to 350°F (175°C).

Make the batter

  1. In a bowl, cream together the sugar and butter.

  2. Add the eggs and mix well.

  3. Stir in the sour milk and baking soda.

  4. In another bowl, combine the flour and baking powder.

  5. Gradually add the dry ingredients to the wet mixture.

  6. Fold in the melted chocolate until well combined.

Bake

  1. Pour the batter into a greased cake pan and bake for 30-35 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Eggs
Provide structure and richness, helping the batter bind and set as it bakes.
Baking soda
Reacts with the sour milk to release gas, helping the cake rise.
Baking powder
Releases gas as it heats, adding lift to the cake.
Flour
Forms the structure that holds the cake together as it bakes.
Sour milk
Adds acidity that activates the baking soda and tenderizes the crumb.
Melted chocolate
Adds flavour and richness, and contributes fat and moisture to the batter.

The step that matters

Gradually add the dry ingredients to the wet mixture. Adding flour in portions and mixing only until combined keeps the batter smooth and limits gluten development, which would otherwise make the cake tough.
