Fat

Higher fat → richer flavour, tenderness, spread. Melted butter → crispy; cold butter → flaky.

Sugar

More sugar → sweeter, crispier edges. Brown sugar adds chew via molasses; white sugar promotes spread.

Eggs

Eggs add structure, lift and moisture. Extra yolk → richer and chewier. Extra white → cakey and drier.

Liquid

Buttermilk activates baking soda, adds tang and moisture. Oil-based batters stay moist longer than butter-based.
