  2. In a bowl, combine flour, sugar, eggs, and baking powder.

  3. Stir the mixture quickly until well combined.

Bake

  1. Pour the batter into a square baking tin.

  2. Bake in the preheated oven until golden.

Roll the cake

  1. Turn the cake onto a flat surface.

  2. Spread with jelly and roll the cake up.

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

What each ingredient does

Flour
Provides the structure that holds the cake's crumb together as it bakes.
Eggs
Add structure and help trap air, giving the cake lift and a light crumb.
Coffee sugar
Adds sweetness and helps keep the crumb tender and browning the surface.
Baking powder
Releases gas in the oven, causing the batter to rise.

The step that matters

Stir the batter quickly until just combined. Overmixing flour develops gluten, which can make the cake tough and dense instead of soft and light.
