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

What each ingredient does

Butter: Adds fat and richness, creaming with sugar to trap air for a tender crumb.
Sugar: Sweetens the cake and helps create a fine, tender texture when creamed.
Eggs: Provide structure and richness, setting as the cake bakes.
Flour: Forms the structure of the cake as its proteins set during baking.
Baking powder: Releases gas in the batter so the cake rises in the oven.
Silken tofu: Adds moisture and a smooth, tender body to the batter.

The step that matters

Beating the batter after adding the flour and liquid mixture. Beating only until smooth after each addition keeps gluten development limited, so the cake stays tender rather than tough and dense.
