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 the batter

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

  2. In a bowl, cream together the brown sugar and butter.

  3. Add the egg and sour milk, mixing well.

  4. In a separate bowl, combine the flour, baking soda, and baking powder.

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

  6. Melt the grated chocolate in boiling water and stir into the batter.

  7. Add vanilla extract and mix until smooth.

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

Brown sugar
Adds sweetness and moisture, and helps the cake brown and stay tender.
Butter
Adds fat for a tender crumb and rich flavor.
Egg
Helps bind the batter and adds structure as it sets in the oven.
Sour milk
Its acidity reacts with baking soda to help the cake rise and tenderize the crumb.
Baking soda
Reacts with the acidic sour milk to release gas, helping the cake rise.
Flour
Provides the structure that sets the cake as the batter bakes.

The step that matters

Adding the baking soda and sour milk to the batter. Baking soda needs an acid to react and produce gas for rising. Mixing the batter promptly after the sour milk and baking soda are combined keeps that gas in the batter, so the cake rises well.
