Leopard 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

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

  2. Beat the egg whites until stiff peaks form.

Make the two batters

  1. In a separate bowl, cream together the white sugar and butter.

  2. Add the sour milk, flour, and baking soda to the butter mixture, mixing well.

  3. In another bowl, combine the egg yolks with brown sugar and the same quantities of sour milk and flour.

  4. Flavor the yolk mixture to taste.

Bake

  1. Drop spoonfuls of the white and brown mixtures alternately into cake pans.

  2. Bake until a toothpick inserted in the center comes out clean.

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

What each ingredient does

Eggs
Whites whipped to stiff peaks add lift and an airy structure; yolks add richness and color.
Butter
Creamed with sugar, it adds tenderness and a rich, fine crumb.
Baking soda
Reacts with the sour milk's acidity to produce gas that helps the cake rise.
Sour milk
Its acidity activates the baking soda and adds moisture and tang.
All-purpose flour
Provides the main structure that holds the cake together as it bakes.
Brown sugar
Adds moisture and a caramel-like depth to the darker batter.

The step that matters

Drop spoonfuls of the white and brown mixtures alternately into cake pans.. Alternating the two batters loosely rather than stirring them together creates the leopard-spot pattern. Overmixing blends the batters into an even color and deflates the whipped whites, reducing rise.
