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 batter

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

  2. In a large bowl, mix together the flour, sugar, baking powder, and salt.

  3. Add the milk and eggs, then stir well until combined.

Bake

  1. Pour the batter into square pans and bake until golden.

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

What each ingredient does

Flour
Forms the structure that holds the cake's crumb together as it bakes.
Eggs
Add structure, richness, and moisture, helping the cake set as it bakes.
Butter
Adds fat for richness and a tender crumb.
Baking powder
Releases gas in the batter, making the cake rise as it bakes.
Milk
Provides the liquid that hydrates the flour and gives the batter its moisture.
Sugar
Adds sweetness and helps the cake brown as it bakes.

The step that matters

Add the milk and eggs, then stir well until combined. Vigorous or prolonged stirring after the liquid goes in develops gluten in the flour, which can make the cake tough and dense. Stir only until the batter is smooth and evenly combined.
