Linzer cake is a combination of my favorite memories – childhood, Christmas and Vienna. Especially Vienna during the Christmas time. Definitely a place to be, to experience Christmas market and enjoy holiday shopping.

Keto baking is something very special for me. I quit sugar few years ago but I don’t want to give up my healthy sweets. Especially during the holidays.

Linzer cake or Linzer tart and Linzer cookies were always on the menu for Christmas holidays in my family. On this way I am continuing that tradition and satisfying my sweet tooth. But, with no guilt sugar free desserts! That’s why I created this low carb recipe for Linzer torte.

How to make sugar free low carb Linzer torte?

Good quality butter

Keto Linzer torte is so easy to make! First rule is to use a lot of great quality butter. If you can get a grass fed butter, you will definitely taste the difference. As you know, this low carb dough has to be very rich and buttery.

Ground almonds

Freshly ground almonds are crucial for this recipe. It’s even better flavor if you roast them just a little bit before grinding.

You may use your food processor for that, however you can make your life easier and use already ground almonds from the market or any store.

Coconut flour

Coconut flour should be a real, defatted coconut flour. Not coconut flakes or shredded coconut. Coconut flour is usual in low carb and keto baking.

Homemade low carb jam

In this keto Linzer torte recipe I use my homemade low carb blueberry jam. Also you can make it with this delicious keto strawberry jam. It will be fantastic!

If you are not so enthusiastic about preparing everything from the scratch you can use some store bought sugar free jam. Just make sure to check ingredients to avoid artificial sugars and similar sweeteners that are not so great choice.

    Hello Ines,
    I’m new to your blog, I just found it the other day on Pinterest when I saw your beautiful Peach Pie and it was made keto! I had to have it! Now here I am looking at all your lovely recipes and see another beautiful fruit dessert that I can’t wait to make. So many things to choose from that look delectable.
