Gluten-Free All-Purpose Flour Blend (No Gums, No Rice Flour)

Store-bought gluten-free all-purpose flour blends often rely on xanthan gum, rice flour, and lots of refined starches like potato starch or tapioca. If your goal is a cleaner blend, with more nutrients, still practical for everyday baking – this is a simple homemade mix you can make from scratch with whole-grain flours and a small binder option (no gums required).

Many gluten-free all-purpose flour blends rely on rice flour and a lot of refined starches to mimic wheat, but not everyone feels great on that combo. For some people, it can be harder to digest and act more like “fast carbs,” leading to a quick blood-sugar spike and an energy crash.

That’s why I created this blend, which uses more nutrient-dense flours like sorghum, millet, and gluten free oats with just a small amount of arrowroot: it’s less processed, brings more fiber and minerals, and tends to be gentler on digestion, while still baking well and offering more for your gut microbes than a mostly-starch mix.

This blend is best for: muffins (like these banana blueberry muffins or strawberry muffins), pancakes (apple pancakes or sweet potato pancakes), waffles, quick breads, sheet cakes like banana cake, coffee cakes, cookies, and as a base for many “everyday” bakes.

For gluten free sourdough breads, buns and yeast breads, it works great too, but you’ll usually add a bit more binder in the recipe depending on the style of bread (more on that below).

If you want a lighter option for delicate bakes, you can also use my gluten-free pastry flour mix (low-starch) it’s designed for a softer, more tender crumb in things like cakes, and pie crust.

How This Blend Works

• Whole-grain base for structure: sorghum + millet + oat (or oat-free swap see below);
• Just enough starch for lift: a small amount of arrowroot keeps crumb lighter without turning the blend starchy;
• Nutritionally enhanced: fewer carbs, more protein, significantly more fiber that makes things still taste good.
• Optional binder (no xanthan): a little psyllium helps reduce crumbling and improves sliceability (especially helpful in egg-free bakes);

What Each Flour Does

• Oat flour: provides softness + natural binding; helps baked goods hold together (I use certified gluten-free + organic brand) or you can ground rolled oats.
• Sorghum flour: provides structure and a mild flavor; keeps texture smoother than many GF grains;
• Millet flour: light whole-grain body; can taste slightly “corn-y” if used too heavily, so it’s balanced here;
• Arrowroot: provides lightness and lift; helps avoid dense bakes without relying on potato/tapioca.

How To Use This AP Gluten Free Flor Mix (for baking, cake, cookies, bread)

• For baking (everyday): Use this blend as the flour base in muffins, pancakes, waffles, snack cakes, quick breads, and bars.
• For cake: Works best in oil-based cakes and sheet cakes.
• For cookies: Great for soft/chewy cookies. For crisp cookies, reduce binder or skip it.
• For bread: Works best for quick breads and simple yeast loaves where you’re okay with a slightly more tender crumb. For yeast breads/rolls, you’ll often add a little extra binder (the optional ingredient) in the recipe liquid for better structure.

Oat flour alternative (no oats option)

If you want the same “all-purpose” feeling without oat flour, here are two options that keep the blend low-starch:

Option 1 (closest texture): swap oat for buckwheat

Oat-free blend (2 cups total):

• ⅔ cup buckwheat flour (light buckwheat if you want lighter color)
• ½ cup sorghum flour
• ½ cup millet flour
• ⅓ cup arrowroot

Binder: psyllium powder/husk still optional for sliceable baked goods. Why it works: buckwheat adds body and binds better than millet alone, without needing rice or tapioca.

Also, millet flour and oat flour can turn bitter when they’ve been sitting too long on the shelves, and those are the two I’ve personally run into most often. To avoid that bitter taste, I frequently grind my own millet and certified gluten-free rolled oats into a fine flour (high-speed blender, small batches) and use it fresh when I need it.

Option 2 (mildest flavor): swap oat for more sorghum

Oat-free, mild blend (2 cups total):

• ⅔ cup sorghum flour
• ½ cup millet flour
• ½ cup fine almond flour (if you tolerate nuts; makes crumb tender + less gritty)
• ⅓ cup arrowroot

Binder: 2 tbsp of psyllium husk, per batch (especially important here).

Notes

• Weigh vs cup: GF flours pack differently, because some brands are superfine and settle heavier; others are coarse and weigh less. Use grams if possible. If using cups, spoon-and-level; don’t pack.
• Resting batter tip: for pancakes/muffins, let batter rest 5 minutes so flours hydrate (better texture, less grit).
• When to skip binder: I often don’t need psyllium except for sliced breads and buns.
• Substitution limits: this isn’t a perfect 1:1 swap for wheat in every recipe; hydration may need small tweaks. If your batter seems thick, add 1–2 Tbsp liquid at a time until it looks like your usual batter.
• Flour texture matters: Superfine-milled gluten-free flours (lighter in color and texture) usually bake up softer, airier, and less gritty, while more artisanal/stone-ground flours (darker, coarser) behave more like whole-wheat, they absorb more liquid and give a heartier, denser crumb.
