Spanish Bun 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 large bowl, cream together the butter and sugar.

  3. Add the flour, sweet milk, baking powder, and cinnamon, mixing until smooth.

  4. Fold in the beaten eggs gently.

  5. Pour the batter into a large square pan.

Bake and finish

  1. Bake for about 30-35 minutes or until a toothpick comes out clean.

  2. Let cool and then ice as desired.

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

What each ingredient does

Eggs
Add structure and richness as they set during baking.
Flour
Forms the structure that holds the cake together as it bakes.
Butter
Adds tenderness and richness to the crumb.
Sugar
Sweetens the cake and helps create a tender, browned crumb.
Baking powder
Releases gas during baking so the cake rises and becomes light.
Sweet milk
Provides moisture that hydrates the flour and keeps the crumb soft.

The step that matters

Folding in the beaten eggs gently. Eggs are beaten separately to add air. Stirring vigorously knocks that air out, so the cake bakes up denser and less light.
