How to Make Self-Rising Flour (4 Steps)

Self-rising flour is simply all-purpose flour with leavening agents added to help baked goods rise. As self-rising flour costs more than all-purpose flour, many people do not keep it on hand. In addition, the shelf life of self-rising flour is a year, so it's likely the bag will go bad before you've used it all. It's easy to make self-rising flour at home with just a few ingredients you likely already have in your cupboards.

Things You'll Need

  • Measuring spoons
  • Measuring cups
  • Butter knife
  • Flour
  • Mixing bowl
  • Salt
  • Baking powder
  • Mixing spoon
  • Plastic zip-close bag or storage container with lid

Instructions

  1. Fill 1 cup with all-purpose flour. Drag the back of a butter knife across the top of the cup to level it. Use a measuring spoon and remove 2 tsp. of flour. Put the excess flour back into the flour bag.

  2. Pour the scant cup of all-purpose flour into the bowl. Measure 1 1/2 tsp. baking powder and 1/2 tsp. salt into the bowl.

  3. Using a mixing spoon, stir the baking powder and salt into the flour mixture. Stir until the ingredients are combined.

  4. Place the self-rising flour into a plastic zip-close bag or storage container with a tightly sealing lid. Moisture and heat does ruin the flour, so it's important to keep it cool and dry until you use it.
