There’s something quietly magical about opening a bag of cake flour and feeling that impossibly soft powder slip through your fingers like silk.
Most home bakers assume cake flour is something you simply buy at the store, but making your own is a game-changer that transforms your baking overnight. Store-bought cake flour can be pricey, inconsistently available, and sometimes contains additives you don’t need.
The beauty of homemade cake flour lies in its simplicity and control. With just two humble ingredients and two minutes of effort, you create a flour that produces cakes with a tender crumb, delicate structure, and that coveted velvety texture that makes people wonder if you trained as a pastry chef.
Whether you’re chasing the perfect angel food cake or building a multi-layer celebration cake, this recipe is your secret weapon. Let’s dive into how to make it and why it works.

My Experience Making This Recipe
I stumbled onto homemade cake flour during a particularly frustrating baking session when my local specialty shop was out of stock. Rather than abandon my layer cake plans, I decided to experiment with blending all-purpose flour and cornstarch.
The difference was immediate and stunning. The cake emerged from the oven with a level of tenderness I’d never achieved before, with a fine, delicate crumb that practically melted on the tongue.
Since that day, I’ve never bought commercial cake flour again. Now every cake I bake gets this treatment, and my family has noticed the improvement in texture and flavor.

Ingredients for Homemade Cake Flour
- All-purpose flour: 1 cup (120 grams), spooned and leveled
- Cornstarch: 2 tablespoons (16 grams)
Ingredient Notes and Substitutions
- All-purpose flour is the base that provides structure and protein to baked goods. If you only have bread flour, reduce the amount to 7/8 cup and add an extra tablespoon of cornstarch to lower the protein content further.
- Cornstarch reduces the protein content of all-purpose flour, which creates a softer, more tender crumb. Potato starch works as a substitute if you cannot find cornstarch, using the same amount.
How to Make Homemade Cake Flour
Step 1: Measure Your All-Purpose Flour
Spoon your all-purpose flour into a dry measuring cup and level it off with a knife, rather than scooping directly from the bag. Scooping compacts the flour and gives you more than you need, which throws off the delicate ratio needed for tender cakes.
Step 2: Measure Your Cornstarch
Use a measuring spoon to measure out exactly 2 tablespoons of cornstarch. This precise ratio is what separates homemade cake flour from ordinary all-purpose flour.
Step 3: Combine in a Bowl or Jar
Pour the measured flour into a small mixing bowl or into a glass jar that you plan to store it in. The jar method is convenient if you want to skip the transfer step later.
Step 4: Add the Cornstarch
Sprinkle the cornstarch over the flour in the bowl. The cornstarch will settle on top initially, but that’s exactly what you want before mixing.
Step 5: Whisk or Stir to Combine
Use a fork or small whisk to stir the mixture vigorously for about 30 seconds until the cornstarch is thoroughly distributed throughout the flour. You want no visible white streaks of cornstarch remaining.
Step 6: Sift the Mixture
Pour the combined flour and cornstarch through a fine-mesh sifter or strainer into another bowl, sifting 2 to 3 times. This aeration step ensures an even texture and removes any lumps that might disrupt your baking.
Step 7: Transfer to Storage Container
Scoop or pour your finished cake flour into an airtight container, label it with the date, and seal it tightly. Proper storage keeps your homemade flour fresh and prevents moisture absorption.
Step 8: Use in Your Favorite Cake Recipe
Substitute this homemade cake flour one-to-one for commercial cake flour in any recipe that calls for it. Your cakes will bake up noticeably more tender and delicate than ever before.
Pro Tip: Sift your cake flour mixture at least twice to ensure the cornstarch distributes evenly, which is the secret to consistent, tender results every single time you bake.
Tips for the Best Homemade Cake Flour
- Measure by spooning and leveling, not scooping, to avoid packing too much flour into your measuring cup. A loosely measured cup of flour makes a huge difference in cake texture.
- Use fresh all-purpose flour within a year of purchase for the best results. Old flour can affect how your cakes rise and set.
- Make a larger batch and store it in an airtight container for up to three months, so you always have homemade cake flour ready when inspiration strikes.
- Sift the finished mixture multiple times to ensure the cornstarch integrates completely and air is incorporated throughout.
- If your cakes still feel slightly dense, try reducing your flour by one tablespoon and increasing the sifting to four times total.
- Keep your storage container in a cool, dry place away from direct sunlight and heat to maintain freshness and prevent clumping.
Common Mistakes to Avoid
- Scooping flour directly from the bag packs it down too much, giving you more flour than intended and resulting in dense, dry cakes. Always spoon and level instead.
- Using the wrong ratio of cornstarch to flour throws off the protein balance and defeats the purpose of making homemade cake flour. Stick to the exact measurements given.
- Skipping the sifting step leaves cornstarch clumps that create uneven texture in your finished cakes. Sift at least twice.
- Storing cake flour in a non-airtight container exposes it to moisture and humidity, causing clumping and reducing its effectiveness.
Serving Suggestions
Homemade cake flour shines brightest in delicate cakes where tender crumb is the main event. Use it in any cake recipe, from simple sponge cakes to elaborate layered creations.
- Classic vanilla layer cake with buttercream frosting
- Airy angel food cake or chiffon cake
- Tender white cake for wedding or celebration tiers
- Fluffy white or yellow cupcakes
- Delicate lemon or almond sponge cake
Variations to Try
- Add one-quarter teaspoon of baking powder to your flour mixture if you want a slight lift in cakes that don’t call for additional leavening, which creates an even lighter crumb.
- Substitute arrowroot powder for cornstarch in a one-to-one ratio if you have a cornstarch sensitivity or prefer a neutral starch option.
- Mix in two tablespoons of fine sugar with your flour for a sweetened cake flour that works beautifully in shortcakes and pound cakes.
- Create a self-rising cake flour by adding one teaspoon of baking powder and one-quarter teaspoon of salt to your standard cake flour mixture for convenience.
Dietary Adaptations
- Gluten-free: Replace all-purpose flour with a one-to-one gluten-free flour blend and maintain the same amount of cornstarch; the results will be slightly different but still tender.
- Dairy-free: This recipe contains no dairy, so it’s naturally suitable for all dairy-free baking needs.
- Vegan: This recipe is completely vegan and works in any vegan cake recipe you choose to bake.
- Low-carb: While this recipe cannot be made low-carb in its traditional form, allulose or monk fruit can replace sugar in cakes baked with this flour, though the substitution may affect texture slightly.
Storage and Reheating
Refrigerator
Store your homemade cake flour in an airtight container on a pantry shelf rather than in the refrigerator, as temperature fluctuations can introduce moisture.
- Lasts up to three months in a cool, dark pantry
- Keep the container tightly sealed between uses
Freezer
You can freeze homemade cake flour for extended storage of up to one year if you want to make large batches ahead.
- Use a freezer-safe airtight container or zip-lock bag
- Thaw to room temperature before opening to prevent condensation
Reheating
No reheating is necessary for cake flour since it’s a dry ingredient used in baking recipes. Simply measure and incorporate into your cake batter as instructed in your recipe.

Frequently Asked Questions
Yes, but you’ll notice a slightly softer, more cake-like texture in your cookies and brownies. For traditional crispy cookies, stick with all-purpose flour instead.
How long does homemade cake flour stay fresh?
Homemade cake flour lasts about three months in an airtight container in a cool, dark pantry. After that, the cornstarch begins to absorb ambient moisture and loses effectiveness.
What if I don’t have cornstarch?
Potato starch works as a direct substitute in equal amounts. If you have neither, reduce your all-purpose flour by two tablespoons and add two tablespoons of fine sugar instead, though the texture will be slightly less tender.
Do I need to sift cake flour before measuring it into recipes?
Most cake recipes assume you’re using store-bought cake flour, which is already sifted, so no additional sifting is necessary. If your homemade cake flour clumps during storage, sift it once before measuring.
Is homemade cake flour really better than store-bought?
Homemade cake flour is fresher, costs less, and contains no additives, which many bakers find produces noticeably better texture. The difference becomes obvious once you taste a cake made with each version side-by-side.
Final Thoughts
Making your own cake flour is one of those small kitchen skills that pays dividends every single time you bake. You’ll spend two minutes and pennies on ingredients, yet notice an immediate improvement in every cake you create from that point forward.
Start with this simple recipe, commit to proper measuring and sifting, and watch your homemade cakes transform into something noticeably more tender and delicate. Your friends and family will wonder what changed, and you’ll have a secret that took only minutes to learn.
