Spanish 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. The book gives no cooking times either; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.

Prepare the batter

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

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

  3. Add the milk and mix well.

  4. In another bowl, combine the flour and baking powder.

  5. Gradually add the dry ingredients to the wet mixture, stirring until just combined.

Fold in the egg whites and bake

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

  2. Gently fold the egg whites and cinnamon into the batter.

  3. Pour the batter into a greased cake pan and bake for 25-30 minutes or until a toothpick comes out clean.

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

What each ingredient does

Eggs
Whipped whites trap air, giving the cake lift and a light, airy crumb.
Butter
Creamed with sugar, it traps air and adds richness and tender texture.
Flour
Forms the cake's structure once mixed with liquid and heat sets it.
Baking powder
Releases gas in the batter, helping the cake rise in the oven.
Sugar
Creamed with butter, it adds sweetness and helps give a tender, browned crust.

The step that matters

Folding in the egg whites. Whites beaten to stiff peaks hold air that gives the cake its lift. Folding gently keeps that air in; stirring hard deflates the batter and yields a dense cake.
