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

  2. Cream together the sugar and butter.

  3. Add the flour, milk, eggs, and baking powder; mix well.

Make the custard

  1. For the custard, boil the chocolate, egg yolk, sugar, and milk until thick; allow to cool.

  2. Stir the cooled custard into the cake batter.

Bake and fill

  1. Divide the batter into two layers and bake.

  2. For the filling, cream together the butter and confectioner's sugar, then flavor with Jamaica rum.

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, add structure, and enrich the crumb.
Butter
Adds fat for a tender texture and rich flavor.
Baking powder
Releases gas in the batter, helping the cake rise.
Chocolate
Supplies the chocolate flavor and deep color of the custard.
Egg yolk
Thickens the custard as it cooks, giving it a smooth, set body.

The step that matters

Cooking the custard until thick. Egg yolk proteins set with heat and can curdle or turn grainy if boiled too hard or too long. Cooking gently and stopping once thick keeps the custard smooth before it is cooled and folded into the batter.
