Plain Mountain 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).

Make the batter

  1. In a bowl, cream the butter and sugar together until light and fluffy.

  2. Add the egg yolks and milk, mixing well.

  3. In another bowl, combine the flour and baking powder, then gradually add to the wet mixture.

  4. In a separate bowl, beat the egg whites until stiff peaks form.

  5. Gently fold the egg whites into the batter.

Bake and finish

  1. Pour the batter into prepared cake pans and bake until golden.

  2. While the cake is hot, spread a mixture of beaten egg whites and sugar between the layers.

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

What each ingredient does

All-purpose flour
Forms the structure that holds the cake's crumb together as it bakes.
Eggs
Whites trap air for lift, and yolks add richness and structure to the batter.
Butter
Fat that tenderizes the crumb and adds richness and flavor.
Sugar
Sweetens the cake, softens the texture, and helps the crust brown.
Baking powder
Releases gas in the batter, causing the cake to rise in the oven.
Milk
Adds moisture and hydrates the flour to form the batter.

The step that matters

Folding in the egg whites. Beaten egg whites hold air that gives the cake lift. Stirring or overmixing deflates them, so the cake bakes up dense and flat. Fold gently, just until no white streaks remain.
