If you’re out of cake flour, a few swaps can get you close.

• Pastry flour: Softer than all-purpose, it can deliver a tender crumb.
• All-purpose + cornstarch: For each cup needed, remove 2 Tbsp all-purpose and replace with 2 Tbsp cornstarch, then sift well.
• Gluten-free 1:1 blends: Labeled for baking; results vary by recipe.

These options can work for cupcakes, snack cakes, and more, though texture and rise may differ from using true cake flour. Start with recipes that don’t rely on a tall, airy structure, and avoid swapping in self-rising flour unless your recipe accounts for added leaveners. On Walmart.com, you can filter by flour type and choose pickup or delivery.

Cake flour is milled to be extra fine and soft, which helps create a delicate, tender crumb in cakes and cupcakes. It’s often sold as bleached or unbleached. All-purpose flour is more robust and versatile, better suited for cookies, quick breads, pancakes, and everyday baking.

• Texture: Cake flour tends to produce softer, lighter bakes.
• Versatility: All-purpose covers more recipe styles.
• Label callouts: Look for terms like unbleached, organic, or self-rising (which includes leaveners).

Choosing between them depends on the recipe style and the crumb you prefer. If you’re shopping online, use filters to compare types and bag sizes for home delivery or store pickup.

You can approximate cake flour with ingredients you may have on hand.

1. Measure 1 cup all-purpose flour.
2. Remove 2 tablespoons.
3. Add 2 tablespoons cornstarch.
4. Whisk or sift the mixture 2–3 times to aerate.

Scale this ratio for larger batches. Sifting helps distribute the starch and lightens the blend, which can improve tenderness, but results vary by recipe and mixing method. If your batter seems thick, a small splash of milk can help loosen it. For the closest texture, avoid overmixing once liquids are added. Always check your recipe for specific guidance on flour type and leavening.

Both options are available, and each can be useful.

• Bleached cake flour: Undergoes a whitening step. It can yield a paler color and a fine, delicate crumb.
• Unbleached cake flour: Skips the bleaching step. It may offer slightly more structure and a creamier hue.

Either can produce great results, so it often comes down to the style you like and what your recipe suggests. When browsing online, check the product title for “bleached” or “unbleached,” review the ingredient list, and choose the bag size that fits your baking routine. Pickup and delivery options can make restocking convenient.

Proper storage helps maintain freshness and performance.

• Transfer to an airtight container or seal the bag tightly.
• Store in a cool, dry place away from heat, light, and strong odors.
• Avoid moisture; use a clean scoop to keep it dry.
• For longer storage, you can refrigerate or freeze in an airtight container; bring to room temperature before measuring to reduce clumping.
• Check the package’s best-by date and look for off smells or pests before use.

Following these steps can help keep your flour consistent from bake to bake, but always refer to the packaging for brand-specific guidance.
