Mix Your Own Gluten-Free Flour Blends

Gluten-free baking gets a lot less mysterious when you stop thinking in terms of one “magic” bag of flour and start thinking in roles. Every good blend needs structure, tenderness, and a little help holding onto moisture. Once you know what each flour and starch does, you can mix exactly what you need for cakes, breads, and pastries, without paying extra for a pre-made blend that may not match your recipe.

The 4-part system

I build gluten-free blends using four categories. Most successful blends are some variation of these:

• Base flour: neutral, reliable backbone (white rice flour, brown rice flour, sorghum flour, millet flour, oat flour if certified gluten-free).
• Starch: lightness and tenderness (tapioca starch, potato starch, cornstarch).
• Structure and flavor flour (optional but helpful): a boost in browning, flavor, and strength. This category includes higher-protein, higher-fiber, or higher-fat flours that help with crumb and sliceability (almond flour, sunflower seed flour, chickpea flour, soy flour, teff). Use small amounts at first.
• Binder: elasticity and “gluten-like” structure (psyllium husk powder for breads, xanthan gum or guar gum for many cakes and cookies).

When a gluten-free bake is gritty, it is often the base flour. When it is dense, it usually needs more starch or more leavening/hydration (depending on what you are baking). When it crumbles, it needs a binder or a touch more structure and flavor flour.

Choose the right binder

Binders are powerful. Too little and your baked goods fall apart. Too much and you get a gummy, stretchy texture that no one asked for. Brands and recipes vary, so treat the amounts below as starting points, then adjust in small increments.

Xanthan gum

• Best for: cookies, cakes, muffins, pancakes, quick breads
• Starting guideline: 1/4 to 3/8 teaspoon per cup of flour blend for cookies and cakes, 1/2 teaspoon per cup for quick breads and muffins

Guar gum

• Best for: cold or no-bake applications and tender cakes (it hydrates differently than xanthan)
• Use similarly to xanthan, but start slightly lower if you are sensitive to gumminess

Psyllium husk powder

• Best for: yeasted breads and chewy rolls (it creates a flexible, dough-like structure)
• Starting guideline: 1 to 2 teaspoons per cup of flour blend, or about 3% to 6% of flour weight (for example, 10 to 20 g psyllium powder per 330 g flour)

Important: Psyllium needs water. If you add psyllium (or increase it), you will almost always need more hydration. The dough will look wetter at first, then tighten as the psyllium gels.

Also important: If you are using a recipe that already calls for xanthan gum or psyllium, do not add more in your blend. Decide where the binder “lives” and keep it consistent.

The master ratios

Here are beginner-friendly ratios I use constantly. Think of them as reliable defaults. You can dial them in as you learn what textures you love.

All-purpose gluten-free blend

• 60% base flour
• 40% starch

Example for 1000 g total: 600 g white rice flour + 250 g tapioca starch + 150 g potato starch.

Cake blend

• 50% base flour
• 50% starch

Optional: swap 10% of the base flour for almond flour for richer flavor and moisture retention.

Pastry and pie crust blend

• 55% base flour
• 35% starch
• 10% structure and flavor flour (almond or oat flour works beautifully)

This little bit of structure and flavor flour helps crust brown and taste less “starchy.”

Yeasted bread blend

• 60% base flour (sorghum + brown rice is a great combo)
• 30% starch
• 10% structure and flavor flour (almond, chickpea, or teff in small amounts)

Then use psyllium husk powder in the recipe (or add it to the blend only if your recipes do not separately include binders).

Go-to blend recipes

In professional kitchens, we weigh because it is consistent and fast. At home, I still recommend weight when possible, especially for gluten-free baking.

If you only have cups: the cup amounts below are approximate. Flour and starch weights vary a lot by brand and how you scoop. For the closest results, spoon into the measuring cup and level it off, or better yet, weigh.

How to scale any ratio

Pick a total weight, then multiply by the percentage. Example: for a 500 g all-purpose blend, do 60% base (300 g) and 40% starch (200 g).

Nomora Everyday GF Blend (makes about 480 g)

• 240 g white rice flour (about 1 1/2 to 2 cups, depending on brand)
• 160 g tapioca starch (about 1 1/4 to 1 1/2 cups)
• 80 g potato starch (about 1/2 to 2/3 cup)

How to use: cookies, brownies, muffins, pancakes, quick breads. Add xanthan gum in the recipe as needed.

Soft Cake GF Blend (makes about 480 g)

• 200 g white rice flour (about 1 1/4 to 1 2/3 cups)
• 200 g tapioca starch (about 1 1/2 to 1 3/4 cups)
• 80 g potato starch (about 1/2 to 2/3 cup)

How to use: layer cakes, cupcakes, tender loaf cakes. Great with buttermilk, yogurt, or sour cream for extra tenderness.

Flaky Pastry GF Blend (makes about 500 g)

• 220 g white rice flour (about 1 1/2 to 1 3/4 cups)
• 140 g tapioca starch (about 1 to 1 1/3 cups)
• 80 g potato starch (about 1/2 to 2/3 cup)
• 60 g almond flour (about 1/2 to 2/3 cup, depending on grind)

How to use: pie crust, galettes, hand pies, scones. Keep everything cold and do not skip the resting time, since gluten-free doughs need hydration time to roll without cracking.

Potato starch vs potato flour

This one trips people up. Potato starch is a refined starch that adds lightness and tenderness. Potato flour is made from whole potatoes and absorbs much more liquid. They are not interchangeable 1:1 in blends, so double-check the label before you dump it in.

How to mix it

You can whisk a blend in a bowl, but for the most even results, I like the jar method.

1. Weigh or measure each flour and starch into a large bowl.
2. Whisk thoroughly for 30 to 45 seconds, scraping the bottom and corners.
3. Transfer to a jar or airtight container.
4. Shake for 10 seconds before each use. Starches settle.

Smart substitutions

Portland grocery stores spoil me, but I still want your blend to work if your options are limited. These swaps keep texture predictable.

• White rice flour: swap with oat flour (certified gluten-free) for a softer, slightly sweet crumb, or sorghum for a more wheat-like flavor.
• Brown rice flour: swap with millet flour for mild flavor, or teff in small amounts for richer, earthier notes.
• Tapioca starch: swap with cornstarch for tenderness, though you may lose a bit of chew and stretch.
• Potato starch: swap with arrowroot starch for a similar softening effect.
• Almond flour: swap with sunflower seed flour (note: it can turn green with baking soda, harmless but surprising) or use oat flour for a nut-free option.

Allergen and flavor notes: Oats must be certified gluten-free to avoid cross-contact. Legume flours (like chickpea) can taste “beany” if you use too much, so keep them to small percentages until you know you like the flavor.

My waste-reduction tip: If you bought a specialty flour for one recipe and it is just sitting there, use it to replace up to 10% of the base flour in your next blend. Small percentages are forgiving and help you learn what that flour does.

Storage and freshness

Gluten-free flours are more prone to going stale or rancid, especially nut flours.

• Room temperature: base flours and starches, airtight, cool pantry, about 2 to 3 months for best flavor.
• Freezer: my favorite for nut flours and blends that include them. Freeze up to 6 months.
• Label your container: write the blend name and date. Future you will be grateful.

Troubleshooting texture

These are the most common issues I see when people start mixing their own blends, plus the simplest adjustments.

• Gritty or sandy: try a finer-milled rice flour, or replace 10 to 20% of rice flour with oat flour. Let batters rest 10 to 15 minutes before baking so flours hydrate.
• Dry: add 1 to 2 tablespoons more fat (oil or butter) per batch, or include 5 to 10% almond flour in the blend. Also check bake time. Overbaking dries out gluten-free goods fast.
• Gummy center: reduce binder slightly, or lower starch a bit and increase base flour. Make sure your oven temperature is accurate and allow a full cool down before slicing.
• Crumbly: add a touch more binder, or add 1 egg (or 1 tablespoon ground flax + 3 tablespoons water) if the recipe allows.
• Dense bread: increase hydration, use psyllium husk powder for structure, and give the dough adequate proof time. Gluten-free yeasted doughs often need a little longer.

FAQ

Do I need xanthan gum in every gluten-free bake?

No. Some recipes rely on eggs, nut butters, or chocolate for structure. But for many cookies, cakes, and especially anything you want to slice cleanly, a small amount helps.

Can I replace a store-bought 1:1 blend with my homemade blend?

Usually yes if your homemade blend is close to a 60/40 base-to-starch ratio. The biggest difference is whether the store-bought blend includes xanthan gum. If it does and yours does not, you will need to add binder to the recipe.

Why do some gluten-free blends taste starchy?

Too much starch, or too little salt in the final bake. Start with the ratios above, and remember that a tiny bump of salt and acid (like buttermilk, yogurt, citrus, or vinegar in yeasted dough) can make gluten-free baked goods taste more like themselves.

A simple next step

If you are new to this, pick one blend to start. Mix a jar of the Everyday GF Blend, then bake two things you already know well, like your go-to chocolate chip cookies and a quick banana bread. Take notes on texture. Adjust one variable at a time. That is how you get confident fast, without wasting ingredients.
