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.

Make 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 sour milk and eggs, mixing well.

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

  5. Stir the flour mixture into the wet ingredients.

  6. Dissolve the grated chocolate in the boiling water and add to the batter.

  7. Mix until smooth and pour into two greased cake pans.

Bake and frost

  1. Bake for 30-35 minutes or until a toothpick comes out clean.

  2. For the frosting, boil the milk and stir in the white sugar.

  3. Add the chocolate and stir until melted and smooth.

  4. Frost the cooled cake layers.

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 give the cake a tender, moist crumb.
Butter
Adds fat for richness and a tender texture when creamed with the sugar.
Sour milk
Its acidity reacts with the baking soda to help the cake rise and stay tender.
Eggs
Add structure and moisture, helping bind the batter and set in the oven.
Flour
Provides the structure that holds the cake together as it bakes.
Baking soda
Reacts with the acidic sour milk to release gas, making the cake rise.

The step that matters

Stirring the flour mixture into the wet ingredients. Once flour meets liquid, gluten begins to form. Mixing only until combined keeps the crumb tender, while overmixing makes the cake tough.
