When a recipe calls for unsifted flour does that mean all purpose only or can I use cake flour? From viewing past forums members have posted that cake flour allows cake layers to rise better.

If a recipe just calls for "flour" then AP (all purpose) is the default to use.

If you wish to substitute cake flour for AP flour here's a link to a handy baking ingredient substitutions chart:
