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.

Prepare the cake

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

  2. Beat the butter until creamy, then stir in the sugar and beat until light.

  3. Add the milk, then gradually mix in the flour and finally fold in the beaten egg whites.

  4. Pour the batter into cake pans and bake until a toothpick comes out clean.

Make the filling

  1. For the filling, combine the white sugar, butter, and sweet milk in a saucepan.

  2. Add the grated chocolate and boil until thick, stirring constantly.

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

What each ingredient does

Egg whites
Whipped and folded in to lighten the batter and give the cake structure as it sets.
Butter
Creamed with the sugar to trap air and add richness and a tender crumb.
Flour
Forms the structure of the cake as the batter sets in the oven.
Baking powder
Releases gas in the batter so the cake rises and becomes light.
Grated chocolate
Melts into the filling to add flavour and thicken it as it boils.

The step that matters

Boil the filling until thick while stirring constantly. Sugar and milk can scorch on the bottom of the saucepan if not stirred, and the mixture thickens as water evaporates and sugar concentrates. Constant stirring keeps it even and prevents burning.
