Sandnøtter (Norwegian Christmas Butter Cookies)

Sandnøtter are one of the most beloved Norwegian Christmas cookies — tender, buttery and made to melt on your tongue. They belong to the traditional syv slag (the “seven sorts” of Scandinavian Christmas baking), and their sandy, crumbly texture comes from one clever ingredient: potato starch. Here’s how I make them from scratch.

Ingredients Equipment Method Notes

Ingredients

  

• 250 g butter 1 cup + 2 tbsp | softened to room temperature
• 250 g granulated sugar 1¼ cups
• 1 large egg
• 1 tsp vanilla sugar or 1 tsp vanilla extract
• 500 g potato starch 2⅔ cups | potato STARCH, not potato flour (see Notes)
• 125 g all-purpose flour 1 cup

Equipment

• Stand mixer | For creaming butter and sugar to a light, airy base
• Digital kitchen scale | Essential here — potato starch is nearly impossible to measure accurately by volume, so weigh it
• 2 Baking sheets | Bake in batches and don't overcrowd
• Fine-mesh sieve | For sifting the starch and flour into the dough so it stays smooth.

Method

 

1. Cream the softened butter and sugar together until pale, light and airy.
2. Add the egg and beat until fully combined.
3. Sift together the vanilla sugar, potato starch and all-purpose flour, then sift into the butter mixture.
4. Knead gently until you have a firm, smooth dough. (Chill 30 min if the dough feels too soft to roll.)
5. Roll into small balls and place on the baking sheets — no more than about 20 per tray so they don't spread into each other.
6. Press each cookie down gently with a fork to make the classic ridged pattern. If the fork sticks to the dough, dip it in a little potato starch first — and again between cookies as needed.
7. Bake at 400°F (200°C) for about 10 minutes. Sandnøtter should stay pale — do not let them brown.
8. Cool completely on the tray, where they firm up.

Notes

Chef’s tip — the starch is the whole point. The high ratio of potato starch is what gives sandnøtter their signature sandy, melt-in-the-mouth crumb (that’s the “sand” in the name). US bakers: reach for potato starch (sometimes labeled potato starch flour), not “potato flour” — they’re different products and potato flour will ruin the texture. Keep the cookies pale; they’re done when set but still light, and they crisp up as they cool. Store in an airtight tin.
If the fork keeps sticking as you press the pattern, dip it in potato starch between cookies — a quick fix that keeps the ridges clean.

What are sandnøtter?

Sandnøtter are a classic Norwegian Christmas cookie and one of the traditional syv slag — the “seven sorts” of cookies many Scandinavian households still bake for the holidays. The name translates roughly to “sand nuts,” and it’s a perfect description: these little butter cookies have a fine, sandy crumb that dissolves the moment you bite in. They’re small, pale and unfussy, marked with the classic fork-pressed ridges on top. Unlike richer holiday bakes, sandnøtter are all about that delicate, short texture — no chocolate, no filling, just butter, sugar and a whisper of vanilla.

What makes sandnøtter so tender

The secret is potato starch. Where most butter cookies rely on wheat flour, sandnøtter swap most of it for starch — that’s what gives them their fine, sandy crumb. A common mistake for bakers outside Scandinavia is grabbing “potato flour” at the store. It’s not the same thing: potato flour is dried, ground whole potato and will turn your cookies dense and gummy, while potato starch is the pure, silky starch you actually want here. In the US it’s usually labeled “potato starch” and sits with the baking supplies or in the kosher aisle. Use potato starch and you’re set.

Tips for perfect sandnøtter

• Weigh your ingredients. Potato starch is almost impossible to measure accurately by the cup — a kitchen scale gives you consistent results every time.
• Cream well. Beating the butter and sugar until pale and airy builds the light texture.
• Keep them pale. Sandnøtter should not brown. Pull them while they’re still light — they finish setting as they cool on the tray.
• Don’t crowd the tray. Around 20 per sheet keeps them from spreading into each other.
• Fork sticking? Dip it in a little potato starch between cookies to keep the ridges clean.

Troubleshooting

My cookies browned. The oven ran too hot or they stayed in too long. Sandnøtter are done when set but still pale — start checking at 8 minutes. They fell apart when I moved them. That’s the potato starch doing its job — they’re fragile straight from the oven and firm up as they cool. Always cool them fully on the tray before lifting. The dough felt too soft to roll. Chill it for 30 minutes; softened butter can leave the dough slack in a warm kitchen.

How to store sandnøtter

Store sandnøtter in an airtight tin at room temperature, where they’ll keep for up to two weeks — the flavor and texture actually settle after a day or two. They also freeze beautifully: layer them between parchment in a sealed container for up to three months, and thaw at room temperature. That make-ahead quality is exactly why they earn a place in the syv slag every December.

Make it your own

A press of a fork gives the classic ridged top, but you can also flatten them with a patterned cookie stamp for a festive look. A tiny pinch of cardamom in the dough leans them even more Scandinavian.
