Almond Flour

What it is

Almond flour is made by blanching whole almonds (removing the skins), then grinding them into a fine powder. It is sometimes confused with almond meal, which is coarser and made from whole (skin-on) almonds — they behave differently in baking, so the distinction matters.

Almonds are tree nuts with no botanical relationship to wheat, barley, or rye. Almond flour is naturally and inherently gluten-free.

Coeliac safety

The main risk is cross-contamination at the processing facility. Some almond flours are manufactured in facilities that also handle wheat or other gluten-containing products. For coeliacs, look for certified GF labelling or brands that explicitly state dedicated gluten-free production.

Almond flour is also a tree nut product — relevant to flag for anyone baking for others, since nut allergies are separate but serious.

Texture & flavour

Almond flour behaves unlike any grain-based flour. It’s high in fat (roughly 50% fat by weight) and protein (~21%), which gives baked goods a moist, tender, almost fudgy crumb. It adds a mild, sweet, buttery nuttiness that enhances rather than competes with most flavours.

It does not absorb liquid the same way grain flours do, and it adds no starch structure. Baked goods made entirely with almond flour are typically softer, denser, and lower-rise. They also brown and caramelise more quickly due to the fat content.

Best uses

• Cakes, tortes, and brownies — where a dense, moist crumb is a virtue, not a flaw
• Macarons (almond flour is the original, essential ingredient)
• Cookies and shortbread — tender, crisp-edged, and naturally rich
• Financiers and friands
• Grain-free pancakes (works well with eggs and banana)
• Crumble toppings and streusel

Not ideal for yeasted bread or anything requiring a light, airy structure.

HTGF tips

• Eggs are essential when baking with almond flour — they provide the structure and binding that gluten and starch would normally offer. Most almond flour recipes use more eggs than you’d expect.
• Don’t substitute almond flour 1:1 for any grain flour without recipe-specific adjustments. The fat and moisture content are too different.
• Almond meal (coarser, skin-on) gives a rustic texture and slightly bitter edge — it works in fruit cakes and crumbles but produces a speckled, denser result in cakes.
• Store in the fridge or freezer. The high fat content means almond flour goes rancid relatively quickly — smell it before using if it’s been in the cupboard for more than a month.

If you don’t have it

For nut-based texture in cakes and bakes, finely ground sunflower seed flour or hazelnut flour can substitute at 1:1, though both have stronger flavours. For Paleo or grain-free recipes, there’s often no easy swap — the fat content and structure of almond flour is fairly unique among GF options. In recipes where it’s one flour among several, replacing with a mix of rice flour and an extra tablespoon of fat (oil or butter) can approximate the result, but test first.
