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

What each ingredient does

Eggs: Bind the batter and add structure and richness as the cake sets.
Rice flour: Provides the gluten-free structure that the cake's crumb is built on.
Butter: Adds fat for a tender crumb and rich flavor.
Sugar: Sweetens the cake and helps it brown and stay moist.
Baking powder: Releases gas during baking so the cake rises.
Buttermilk: Adds moisture and acidity that works with the leavening.

The step that matters

Slowly stir in the dry mix. Overmixing once the flour is added develops little gluten in gluten-free batter but can still toughen the crumb and deflate the air held in the batter. Gentle, brief stirring keeps the texture light.
