Baked item whose name suggests how much of each ingredient to use

POUNDCAKE

This classic dessert’s recipe traditionally calls for a pound of each key ingredient.

The clue hints at "pound cake," a dessert where the name comes from its original recipe—one pound each of butter, sugar, eggs, and flour. The wordplay lies in "baked item" pointing to cake and "how much of each ingredient" referencing the "pound" in its name. It’s a classic example where the answer’s meaning is hidden in plain sight.
