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.

Make the batter

  1. Cream together the sugar and butter until light and fluffy.

  2. Melt the chocolate over hot water and add it to the mixture.

  3. Incorporate the beaten eggs and mix well.

  4. Add the water and stir until combined.

  5. Sift together the flour and baking powder, then fold into the batter.

Bake

  1. Bake in layers at 350°F (175°C) until a toothpick comes out clean.

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

What each ingredient does

Flour
Provides the structure that holds the cake's crumb together as it bakes.
Eggs
Bind the batter and help set the structure as the cake bakes.
Baking powder
Releases gas during baking so the cake rises and becomes light.
Butter
Creaming with sugar traps air and adds richness and a tender texture.
Sugar
Sweetens the cake and helps create a light, fluffy texture when creamed.
Chocolate
Adds chocolate flavour and deep colour to the batter.

The step that matters

Bake until a toothpick comes out clean. Baking too briefly leaves wet batter in the centre, while overbaking dries the crumb. A clean toothpick shows the structure has set without drying out.
