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

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

  2. In a bowl, mix the flour and sugar together.

Make the batter

  1. Beat the eggs well and add them to the flour mixture.

  2. Cream the butter and add it to the mixture.

  3. Mix everything until well combined.

  4. Pour the batter into a buttered cake pan or small buttered tins.

Bake

  1. Bake for 30 minutes or until golden brown.

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

What each ingredient does

All-purpose flour
Provides the main structure that holds the cake's crumb together as it bakes.
Granulated sugar
Sweetens the cake and helps it brown while tenderising the crumb.
Eggs
Add structure and lift through their proteins, and help bind the batter.
Unsalted butter
Adds fat for a tender texture and rich flavour.

The step that matters

Beat the eggs well before adding them to the flour mixture. Well-beaten eggs trap air that helps the cake rise, and adding them gradually keeps the batter smooth so it bakes evenly.
