In brief
Pound cake takes its name from a traditional formula with equal quantities of butter, sugar, flour and eggs.
Useful to know
Pound cake takes its name from a traditional formula with equal quantities of butter, sugar, flour and eggs. King Arthur’s modern version changes the proportions and adds a little baking powder. [1]
The name therefore cannot reconstruct every recipe’s exact formula. Check the quantities and how air is incorporated. The source alternates dry and liquid ingredients to limit excessive mixing. A dense, buttery crumb can be an intended characteristic rather than evidence that the cake has failed.
