There is something undeniably magical about a tray of Linzer cookies. For years, I looked at those delicate, powdered “stained glass” windows at holiday parties with a mix of admiration and hesitation. I knew the traditional combination of white flour and heavy jams would leave me feeling sluggish and foggy within an hour. But I missed them. I missed that specific, sandy crumble of the nut dough and the tart brightness of the fruit filling.
I realized I didn’t have to choose between festive aesthetics and feeling my best. By leaning into the traditional Austrian roots of this recipe—which already favors almond meal—I found a way to recreate that elegance without the heavy sugar load. These cookies are tender, buttery, and bright with lemon zest. They are my proof that we can honor our favorite seasonal traditions while sticking to a plan that supports steady energy.
Why These Jeweled Treats Are My Holiday Staple
The beauty of this recipe lies in the almond flour. In many modern cookies, we force low-carb ingredients to mimic wheat, but Linzers want to be nutty. The almond flour provides that classic, tender bite that melts in your mouth, rather than the chewy texture of a standard sugar cookie.
I also add a generous amount of fresh lemon zest to the dough. It cuts through the richness of the butter and erythritol, making the cookie taste sophisticated rather than just “sweet.” It’s a recipe I turn to when I want to impress guests who might be skeptical of “healthy” desserts. Most of the time, they have no idea these are any different from the bakery version until I tell them.
Fitting Sweet Traditions into a Conscious Lifestyle
Navigating the holiday season while managing carbohydrate intake can feel tricky, but I’ve found that having a reliable, diabetes-friendly option makes all the difference. Instead of feeling restricted, I feel empowered to enjoy a treat.
This recipe is designed with blood sugar in mind. By swapping traditional sugar for erythritol and using a high-fiber almond flour blend, the impact on the body is significantly gentler than a standard cookie. However, they are still a rich, calorie-dense treat, so I treat them as a “mindful indulgence.”

My Kitchen Notes for Flawless Bakes
Working with gluten-free, low-carb dough requires a slightly gentler touch than traditional baking. Over the years, I’ve learned a few tricks to ensure these come out perfect every time.
- Chill is Non-Negotiable: This dough relies on butter for structure. If it gets too warm, it becomes impossible to cut into those pretty shapes. I always chill the dough discs before rolling, and I chill the cut shapes again before baking. This prevents them from spreading into unrecognizable blobs in the oven.
- Watch the Edges: Almond flour browns faster than wheat flour. I keep a close eye on the oven around the 12-minute mark. You want the edges to be barely golden, not brown.
- Cool Completely: When these come out of the oven, they are extremely fragile. If you try to move them immediately, they will crumble. I let them sit on the baking sheet for at least 5 minutes before transferring them to a rack.
Crafting the Perfect Windowpane Cookie
The assembly is where the fun happens, and it’s a great step to get kids involved in. Once the cookies are fully cooled, I separate the solid bottoms from the window tops.
I dust the tops with powdered sweetener before assembling. This keeps the red jam window bright and shiny, rather than getting covered in white “snow.” Then, I spread a small teaspoon of sugar-free raspberry or strawberry jam onto the bottom cookie.
You don’t need much filling—just enough to reach the edges when you gently press the top down. The result is a cookie that looks professional but is actually quite simple to put together.
Common Questions About Low-Carb Holiday Baking
Are these cookies suitable for someone with diabetes?
In my experience, yes, they can be a great fit. With approximately 11g of net carbs per cookie, they are much lower in carbohydrates than traditional Linzers. However, everyone responds differently to sugar alcohols and almond flour. I recommend enjoying one as part of a balanced meal—perhaps paired with some protein—rather than on an empty stomach.
How do I serve these to ensure a balanced snack?
Since these are low in protein, I like to pair them with something that rounds out the nutritional profile. They go beautifully with a warm, cozy drink. I often serve a cookie with a mug from my list of 15 Homemade Cinnamon Tea Recipes. The warmth of the tea and the richness of the cookie make for a very satisfying, sensory experience that doesn’t require overindulging.
Can I use a different sweetener?
I use erythritol because it provides a crunch similar to sugar. If you prefer monk fruit or allulose, those work too, though allulose may cause the cookies to brown faster and soften more quickly. If you are sensitive to the cooling effect of erythritol, a monk fruit-erythritol blend is often smoother on the palate.

- Cuisine: Austrian-American
Description
These buttery, tender sandwich cookies offer the classic elegance of traditional Linzers with a lighter, modern touch. Infused with a hint of fresh lemon zest to brighten the almond flavor, this version uses erythritol and sugar-free fruit spread to keep the sweetness high while being mindful of carbohydrate intake. It is a delightful, festive treat designed to fit into a balanced lifestyle, offering a comforting bite that may support steady energy levels.
Ingredients
2 ½ cups All-purpose flour (bleached or unbleached)
¼ tsp Salt (fine sea salt)
1 cup Unsalted butter, softened (2 sticks)
1 large Egg (room temperature)
1 tsp Vanilla extract
1 tsp Lemon zest (freshly grated)
¼ cup Sugar-free powdered sweetener (for dusting)
Instructions
In a medium mixing bowl, sift together the all-purpose flour, almond flour, and salt. Whisk gently to ensure the almond flour is evenly distributed and free of clumps. Set aside.
In a large bowl or stand mixer fitted with the paddle attachment, cream the softened butter and erythritol together on medium speed until the mixture is pale and fluffy (about 2-3 minutes).
Lower the mixer speed and beat in the egg, vanilla extract, and fresh lemon zest until fully incorporated. Scrape down the sides of the bowl with a spatula.
Gradually add the dry flour mixture to the wet ingredients in two batches, mixing on low speed just until a soft dough forms. Do not overmix.
Divide the dough in half and shape each portion into a flattened disc. Wrap tightly in plastic wrap and refrigerate for at least 30 minutes to firm up.
Preheat your oven to 325°F (165°C). Line two large baking sheets with parchment paper.
Lightly flour a clean surface. Roll out one disc of dough to approximately ¼-inch thickness. Use a 2.5 to 3-inch round or fluted cookie cutter to cut out the base shapes.
Cut an equal number of shapes for the tops. For the top cookies, use a smaller 1-inch cutter (star, heart, or circle) to remove the center, creating the “window.” Reroll scraps as needed to utilize all dough.
Arrange the cookies on the prepared baking sheets, leaving about an inch of space between them. Chill the trays in the refrigerator for 15 minutes before baking (this prevents spreading).
Bake for 14-16 minutes, or until the edges are just barely set and light golden. The tops should remain pale.
Remove from the oven and let the cookies cool on the baking sheet for 5 minutes before transferring them to a wire rack to cool completely. They must be fully cool before filling.
Once cool, dust the “window” top cookies generously with the sugar-free powdered sweetener. Spread about one teaspoon of sugar-free jam onto the flat side of each solid bottom cookie.
Gently press the dusted top cookies onto the jam-covered bottoms to form the sandwich. Serve immediately or store in an airtight container.
Notes
- Mindful Enjoyment: While these cookies are a lighter alternative to traditional Linzers—using sugar-free ingredients to minimize the direct impact on blood sugar—they remain a rich, butter-based treat. Since they are lower in fiber and contain saturated fats, they are best enjoyed as a single, petite indulgence alongside a balanced meal to help manage saturated fat intake.
- Allergy Alert: This recipe contains Wheat (Gluten), Tree Nuts (Almonds), Dairy (Butter), and Egg. For a nut-free version, replace almond flour with an additional ½ cup of all-purpose flour, though this will slightly increase the carbohydrate count.
- Storage: These cookies soften over time as the jam hydrates the cookie. They are best enjoyed within 3 days if stored at room temperature, or they can be frozen (unfilled) for up to a month.
