Why You’ll Love This Easy Cake Flour SubstituteThis trick requires just two ingredients and takes just 2 minutes to make! Here’s why when you learn how to make cake flour from all-purpose at home, you’ll never look back:

Better Ingredients – You know exactly what’s in it. You can choose to use organic unbleached flour, which is tough to come by in the limited cake flour selection in the baking aisle.

Save Money – It’s way less expensive to make it yourself and your results will be equally amazing.

Convenient – No need to keep this extra ingredient in your pantry when you can make it without much fuss.IngredientsYou only need two pantry staples to make cake flour–once you see how much extra you are paying at the store, you’ll never bother with the boxed stuff again.

All-purpose flour – Be sure to measure the flour correctly

Cornstarch – Make sure you are getting cornstarch and not corn flour or cornmeal. Look for cornstarch that has just one ingredient on the label: cornstarch. Pro Tip:Note that this recipe makes 1 cup of cake flour. If your recipe calls for 2 cups, be sure to double proportionally to 2 cups (removing 4 Tablespoons) and the cornstarch to 4 Tablespoons.

How to Make Cake FlourTake just two minutes to prepare this substitute, and you’ll love the airy texture of the finished product.

Measure all-purpose flour into a measuring cup by scooping it from the flour bin and scraping the top off evenly with the back of a knife. Then use a tablespoon to remove 2 Tablespoons of the flour from the cup.

Add 2 Tbsp cornstarch to your cup of all-purpose flour. I add it directly into the measuring cup.

Sift the two ingredients together over a sheet of parchment or into a mixing bowl several times, making sure the two ingredients are well combined. I used the fine mesh sieve (actually, I use it for everything!).How to Store Cake FlourOnce the homemade cake flour is made, store it in your pantry in an airtight container in a cool, dry and dark place. Store away from sunlight and moisture. Check the expiration on your flour and cornstarch, and that is typically the expiration of your cake flour substitute, about 6 to 8 months. The flour is ready to use when you need it!

What is the difference between Cake Flour and All-Purpose Flour?Cake flour has a lower protein and gluten content and a finer consistency than all-purpose flour, which gives desserts a softer, fluffier texture. You can use this homemade substitute in any recipe that calls for cake flour, like our Storybook Cake Roll and Honey Cupcakes.
Cake flour substitute can come in handy when you need to make a recipe but don’t have it on hand. I love that you can make it from better ingredients for cheaper and in the quantity you need. Try this kitchen hack today!
