Ingredients

Directions

Make the dough

  1. Combine the light dough, melted butter, sugar, beaten eggs, dissolved baking soda, and salt in a bowl.

  2. Add enough flour to make the dough stiff enough to knead well.

  3. Set the dough aside to rise until light.

Shape and bake

  1. Roll the dough into cakes about ½ inch thick to fit your pans.

  2. Place one cake in the pan, cover it with soft butter, and lay another cake on top.

  3. Allow the cakes to rise again until light.

  4. Bake until golden and serve immediately.

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

What each ingredient does

Light dough from hop yeast
Provides the leavening that makes the cake rise and gives it an airy crumb.
Eggs
Add structure and richness, helping the cake hold its shape while baking.
Sugar
Sweetens the cake and helps the crust turn golden as it bakes.
Melted butter
Adds fat for tenderness and a rich flavour in the crumb.
Baking soda
Reacts with the dough's acidity to help it rise and lighten the texture.

The step that matters

Letting the dough rise until light. Yeast needs time and warmth to build gas bubbles that give the cake its lightness. Rising too briefly leaves a dense crumb, and over-rising can collapse the structure before baking.
