Chocolate Layer 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, beat the egg whites until stiff peaks form.

  3. In another bowl, cream together the sugar and butter.

  4. Add the egg yolks and sweet milk to the sugar mixture, and mix well.

  5. Sift together the flour and baking powder, then gradually add to the wet mixture.

  6. Divide the batter in half; to one half, add the grated chocolate and mix well.

Bake and assemble

  1. Pour the light batter into two greased cake pans and bake for 25-30 minutes.

  2. Pour the chocolate batter into another greased pan and bake for 25-30 minutes.

  3. Once baked, layer the cakes alternately, spreading chocolate icing between each layer.

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

What each ingredient does

Eggs
Yolks enrich and bind the batter, while whipped whites add lift and a light crumb.
Flour
Provides the structure that holds the cake together as it bakes.
Sugar
Sweetens the cake and helps create a tender, browned crumb.
Butter
Adds fat for richness and a tender texture.
Baking powder
Releases gas during baking so the cake rises and becomes light.
Grated chocolate
Adds chocolate flavor and deepens the color of one batter.

The step that matters

Folding in the beaten egg whites. Whipped whites trap air that gives the cake its lift; deflating them by overmixing leaves a dense, flat cake. Stir gently and stop once combined.
