Please choose the correct ending to complete the given sentence: Food and Entertaining: [header] How to bake soft cookies [title] Use cake flour instead of all-purpose flour.

If your recipe calls for shortening, use it instead. Ending3: [substeps] When you're baking cookies, it might make sense to opt for powdered flour. This will add the crunchy texture of classic sweet cookies while still giving the tart-tinged flavor of traditional southern cookies. Ending4: [substeps] Consider using whole wheat flour instead of whole-wheat. This is a lighter form, and has a bit of a crunch.
