Yes — almond flour is keto. A ¼-cup serving has just 3 grams of net carbs, versus about 24 grams in the same amount of all-purpose flour. That’s an ~87% drop, and it’s why almond flour is the backbone of low-carb baking.
It’s the flour I reach for first, and the reasons matter more than the one-word answer. Below: the carb math (so you can check it yourself), how almond flour compares to the other flours, and why it works so well on keto.
How many carbs are in almond flour?
This is the label I read before any almond flour goes in my cart. Here’s what’s in a standard ¼-cup serving (28g) of blanched almond flour:
- Calories: 160
- Fat: 14g
- Protein: 6g
- Total carbs: 6g
- Fiber: 3g
- Net carbs: 3g
- Sugar: 1g
Three grams of net carbs is about as low as baking flour gets. And unlike wheat flour, which is basically pure starch, I’m getting real fat and protein out of it. That’s the reason I can build a whole dessert around almond flour and still land inside my macros.
How to calculate net carbs in almond flour
Here’s how I count it for every recipe on this site. Net carbs are the carbs that actually move your blood sugar, and the formula is simple:
Net carbs = total carbs − fiber − sugar alcohols
For almond flour, that’s 6g total carbs minus 3g fiber, which leaves 3g net carbs per ¼ cup. (There are no sugar alcohols in plain almond flour, so nothing to subtract there.)
I subtract the fiber because your body doesn’t break down or absorb most of it the way it does starch and sugar, so it barely touches your blood glucose. With almond flour, half the carbs are fiber, which is exactly what I want in a keto flour.
Almond flour vs. other flours
I’ve baked with all of these, and here’s how they actually stack up per ¼ cup:
| Flour (per ¼ cup) | Net carbs | Total carbs | Fiber | Keto-friendly? |
|---|---|---|---|---|
| Almond flour | 3g | 6g | 3g | ✅ Yes |
| Coconut flour | ~6g | ~16g | ~10g | ✅ Yes (use far less) |
| All-purpose flour | ~24g | ~25g | ~1g | ❌ No |
| Whole wheat flour | ~21g | ~24g | ~3g | ❌ No |
Almond flour wins for me on net carbs and on how it behaves. Coconut flour is keto too, but it’s a different animal: so absorbent that I use about a quarter of the amount and add extra eggs, or it bakes up dry. All-purpose and whole wheat are simply too starchy to fit into a keto day, full stop.
Why almond flour works so well on keto
Low net carbs is only half of why I lean on it. Keto isn’t just “avoid carbs.” It’s high fat, moderate protein, and almond flour fits that profile without me even trying: 14g of fat and 6g of protein per serving. All-purpose flour gives me none of that; it’s pure starch. So almond flour doesn’t just squeak under my carb limit, it actively helps me hit my macros. After years of testing, that’s why it became my default.
Is almond flour or coconut flour better for keto?
Both are keto, and I keep both in my pantry. I reach for almond flour for most baking: cookies, breads, cakes, anything I want a tender, familiar crumb. I save coconut flour for lighter, more cake-like textures, or for nut-free baking. One rule I learned the expensive way: never swap coconut flour 1:1 for almond flour. It drinks up so much liquid that you need roughly ¼ the amount plus extra eggs, or you’ll pull a dry, dense brick out of the oven.
How to bake with it
A few things I wish someone had told me before my first almond-flour bake:
- Buy blanched, super-fine almond flour, not almond meal (coarser, skins on). Almond meal is the number-one reason keto cookies come out gritty and crumble apart. I learned that the hard way before I switched.
- Plan on about 1 cup of almond flour for every ⅓ cup of all-purpose, plus an extra egg or two for structure. There’s no gluten to do that job, so the eggs hold everything together.
- Store it cold. It’s high in fat and turns rancid on the counter faster than you’d think — I keep mine in the freezer and pull it out 30 minutes before I bake.
I’ve put everything else I’ve learned (the brands I trust, the ratios, how it handles moisture, and the fixes for when a bake goes sideways) plus 150+ tested recipes in one place:
