A holiday classic gets a healthy makeover! These Keto Butter Cookies are buttery and crisp, and piped in festive swirls. Dip them in chocolate or leave them plain, it’s up to you.
Remember those Danish butter cookies making the rounds every holiday season? You know the ones – they came in a pretty blue metal tin and the cookies were all nestled in fluted paper cups.
Every house had them, back in my childhood. It was standard holiday issue, usually gifted by some aunt, grandmother, or coworker. They were tasty but the tin usually lasted so long, they grew stale before you could eat them all.
Well, you no longer need to mourn those holiday memories, because Keto Butter Cookies have arrived! And they are just as buttery, tender, and sweet as the real thing.
They look so festive on a cookie tray, along with other favorites like Keto Sugar Cookies and perhaps a few Chewy Keto Ginger Cookies. How can you resist?
Why you will love these cookies
I can’t tell you how fun it was to tackle this classic cookie recipe. I actually had to tackle it a few times, as the first few batches simply didn’t live up to the butter cookies of my memory.
It’s a tricky thing to get right, a soft dough that you can pipe into pretty swirls, whilst also being firm enough to not completely dissolve during baking. All the more tricky with keto ingredients!
But it was worth it to me to persevere. I found that if I let them sit in a warm oven, they got firmed up without browning too much. They stayed super buttery, but with a delightful crispness. Just like the real deal.

Ingredient Notes
- Almond flour: Use finely ground almond flour so your cookies will have the best texture without being grainy. If you need to be nut-free, try using sunflower seed flour.
- Sweetener: You need an erythritol based sweetener for these cookies to firm up properly.
- Butter: If you use salted butter, you can omit the additional salt in the recipe. Be sure to use softened butter for better consistency.
- Sugar-free dark chocolate: Both Lily’s and ChocZero work well for the chocolate coating.
- Cocoa butter: I add a little cocoa butter to the melted chocolate for a smoother melt. You can also use ½ tablespoon to 1 tablespoon coconut oil, but they will be much more melty at room temperature.
- Sugar-free sprinkles: If you want to decorate your cookies with a little something extra, you can use store bought or homemade sugar free sprinkles. You could also use finely chopped nuts.
- Pantry staples: Eggs, vanilla extract, and salt.
Step by step directions
1. Combine the dry ingredients: In a food processor, combine the almond flour, sweetener, and salt. Pulse to combine.
2. Add the wet ingredients: Cut the softened butter into chunks and add to the processor. Pulse until the mixture resembles coarse crumbs. Add the egg and vanilla and process until the dough clumps together.
3. Pipe the cookie dough: Fit a piping bag with a large open star tip such as the Ateco #826 or 828, and fill with dough. Holding the bag straight up and down, pipe the dough into tight circles, about 2 inches in diameter, onto two baking sheets lined with silicone baking mats or parchment paper.
4. Bake the cookies: Bake at 325ºF for about 18 to 20 minutes, until they are just golden brown around the edges. Remove and turn off the oven. Let the oven cool for about 15 minutes, then put the cookies back in to dry out and firm up, another 15 to 20 minutes or so. Remove and let cool completely.
5. Dip in chocolate: In a heatproof bowl set over a bowl of barely simmering water, melt the chocolate and cocoa butter. Dip half of each cookie into the chocolate and set on a waxed paper lined baking sheet. Sprinkle with sugar-free sprinkles, if desired.
Tips for Success
Using a food processor makes the dough more cohesive and very well combined. I first tried just beating things together in my stand mixer but it didn’t produce as fine a dough and the resulting cookies had a slightly gritty texture.
Make sure that butter is well softened. This is an important factor too, as it helps create a softer dough that squeezes through the piping tip. The ideal temperature for softened butter is 70F. If your house is a bit chilly, give the butter a slight zap in the microwave (10 seconds).
Use a larger open star piping tip. The tip you use for piping these cookies is very important, as the prongs need to be open enough to allow the dough to squeeze through. I used the Ateco 824, but the Wilton 1M tips can work as well.
It takes a bit to get the hang of piping these cookies. But the good news is that if you mess up, you can just add the dough back into the bag to be re-piped.
Double baking helps crisp them up. Danish butter cookies should be quite crisp but you also want them a pale golden color. To avoid over-browning, I took mine out at about the 20 minute mark, but then I returned them to the warm oven for a bit to help them crisp up. Worked like a charm!
As always, your sweetener matters. The only way to achieve a truly crisp cookie is with erythritol based sweeteners such as Swerve. Other sweeteners like BochaSweet, allulose, etc, make for cake-y soft cookies. Not necessarily a bad thing but not the perfect Danish Butter Cookie consistency.
Frequently Asked Questions
Keto shortbread cookies are made like classic shortbread, which means they don’t contain any egg. These keto butter cookies have an egg to help make the dough pliable and soft, so that it can be piped into shapes.
You can easily store these cookies in freezer. Once baked and cooled, place them in an airtight container between sheets of waxed paper. They will keep for up to 2 months.

Joanne says
When you say powdered sugar do I use Swerve confectioners sugar? Or is there something else I should use?
Carolyn says
I don’t say powdered sugar… I say powdered sweetener. And I think I outline what the best options are in the tips? :). but yes, Swerve confectioners would be a good choice here.
Aliya says
what about powdered xylitol (pure birch sugar) does that change texture or anything?
Carolyn says
Yes, it will make them much softer and less crisp.
Donna says
Can you put the dough in a cookie press?
Carolyn says
No, it’s too soft. Please search my site for spritz cookies.
Linda says
Delicious and so simple to make. They look and taste great. Definitely recommend this recipe
VAnny says
we don’t need baking powder or baking soda?
Carolyn says
No… you don’t want them to rise and lose their shape.
Diane says
Have you made these with allulose or a blend of sweeteners? I don’t tolerate erythrytol well.
Carolyn says
They simply won’t crisp up enough. Sorry!
Jana Gallagher says
Do I have to pipe these? can’t I just roll them out or make into balls then press?
Janie says
New to Keto baking. I have all the ingredients with the exception of the cocoa butter. Is there a substitution for the cocoa butter? These look fabulous. Thank you.
Carolyn says
You can use a little coconut oil but they are meltier at room temp.
corina says
can we substitute coconut manna?
