Vanilla Buns

Oven, in the book's wordsA moderate oven

Ingredients

Directions

The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.

Prepare

Preheat the oven to 350°F (175°C).

Make the dough

Beat the butter until creamy.
Gradually add the flour and sugar to the butter.
In a separate bowl, beat the eggs and mix in the vanilla extract.
Pour the egg mixture over the flour mixture and combine well.

Shape and bake

Form the mixture into buns and place them on a baking sheet.
Bake for 45 minutes.

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

What each ingredient does

All-purpose flour: Provides the structure that holds the buns together as they bake.
Sugar: Adds sweetness and helps the buns brown during baking.
Butter: Adds fat for a tender texture and rich flavor.
Eggs: Bind the mixture and add structure and moisture.
Vanilla extract: Adds a distinct aroma and flavor.
