Sachertorte, a rich and decadent Austrian chocolate cake, is renowned for its dense chocolate layers, tangy apricot jam filling, and smooth chocolate glaze. While traditionally high in sugar and carbs, this keto adaptation retains the luxurious flavors without compromising on a low-carb lifestyle. Keto Sachertorte is a grain-free, gluten-free, and sugar-free version of the classic dessert, making it perfect for those following a ketogenic diet.
Key Ingredients for Keto Sachertorte
The keto version of Sachertorte requires swapping out the high-carb ingredients for keto-approved alternatives that still deliver the rich flavors and textures of the original cake.
Low-Carb Flour Alternatives
- Almond Flour: The best choice for keto baking, almond flour provides a nutty flavor and a moist, dense texture that works perfectly for this cake. It’s also gluten-free, making it suitable for those with gluten sensitivities.
- Coconut Flour (optional): Coconut flour can be used in small quantities to add texture and enhance moisture retention. However, because coconut flour absorbs a lot of liquid, it should be used sparingly.
Keto-Friendly Sweeteners
- Monk Fruit Sweetener: This natural, zero-calorie sweetener is ideal for keto baking as it doesn’t spike blood sugar levels. It provides the right level of sweetness without an aftertaste.
- Erythritol or Stevia: These sugar alcohols are commonly used in keto recipes for sweetness. Erythritol offers a mild sweetness, while stevia is a more potent sweetener—both help mimic the flavor of sugar without the carbs.
Keto-Approved Chocolate
- Dark Chocolate (85% or Higher): For the rich chocolate flavor essential to Sachertorte, use dark chocolate with at least 85% cocoa content. There are also sugar-free dark chocolate options available that work well for the glaze and cake layers.
Sugar-Free Apricot Jam Substitutes
- Homemade Keto Apricot Jam: You can easily make your own apricot jam by using fresh apricots or dried apricots (with no added sugar), sweetened with keto-friendly sweeteners like erythritol or monk fruit.
- Store-Bought Sugar-Free Jam: Look for sugar-free apricot jam made with natural sweeteners, available in many health food stores or online.
Additional Ingredients
- Eggs: Eggs help create structure and bind the ingredients together. They’re a key component in keto baking to ensure the cake holds its shape while staying moist.
- Butter or Coconut Oil: Both options provide the necessary fat content for a rich and moist cake. If you’re dairy-free, coconut oil is a great substitute.
Step-by-Step Keto Sachertorte Recipe Instructions
Making a Keto Sachertorte may seem complicated, but with the right ingredients and a methodical approach, you can recreate this luxurious dessert with ease.
Making the Keto Chocolate Cake
- Preheat the Oven: Preheat your oven to 180°C (350°F). Grease a 9-inch springform pan and line the bottom with parchment paper to prevent sticking.
- Melt the Chocolate: In a double boiler, melt your keto-approved dark chocolate with butter (or coconut oil) until smooth. Set it aside to cool slightly.
- Mix Dry Ingredients: In a large mixing bowl, combine almond flour, cocoa powder, and a pinch of salt. These dry ingredients form the base of the cake and ensure it’s gluten-free and low-carb.
- Beat the Eggs and Sweetener: In a separate bowl, beat the eggs and sweetener (monk fruit or erythritol) until light and fluffy. This step helps the cake achieve a light, airy texture despite being flourless.
- Combine Wet and Dry Ingredients: Slowly fold the melted chocolate mixture into the egg mixture, then gently fold in the almond flour mixture. This creates a thick, rich batter that will bake into a dense, moist cake.
- Bake the Cake: Pour the batter into the prepared pan and smooth the top. Bake for 35-40 minutes, or until a toothpick inserted in the center comes out clean. Let the cake cool completely before slicing.
Preparing the Sugar-Free Apricot Jam Filling
The apricot jam layer is essential to the authentic flavor of Sachertorte, providing a tangy contrast to the rich chocolate cake. Here’s how to make a sugar-free version that’s keto-friendly.
- Prepare Apricots: If you’re using fresh apricots, dice them and cook in a small saucepan with a bit of water until softened. If using dried apricots, soak them in hot water until they soften, then blend.
- Sweeten the Jam: Add a keto-friendly sweetener (such as erythritol or stevia) to taste, and a squeeze of lemon juice for brightness. Simmer until the jam thickens.
- Cool the Jam: Once thickened, remove from heat and let it cool before spreading. If the jam is too runny, you can add a small amount of chia seeds to help thicken it without adding carbs.
Assembling the Cake Layers
Once the cake is baked and cooled, it’s time to slice it into layers and assemble the classic Sachertorte with its iconic apricot jam filling.
- Slice the Cake: Using a serrated knife, carefully slice the cake horizontally into two even layers. If your cake is too delicate, you can leave it as a single layer and just spread the jam on top.
- Spread the Jam: Spread a generous amount of the sugar-free apricot jam over the bottom layer, ensuring even coverage. Place the top layer of the cake over the jam.
- Seal with Jam: Optionally, spread a thin layer of the apricot jam over the top and sides of the cake. This helps the glaze adhere and adds an extra layer of flavor.
Creating the Keto Chocolate Glaze
The smooth, glossy chocolate glaze is one of the most recognizable features of Sachertorte. For the keto version, we use sugar-free dark chocolate combined with heavy cream or coconut cream to create a rich, shiny coating.
- Melt the Chocolate and Cream: In a double boiler, melt the sugar-free dark chocolate along with heavy cream (or coconut cream for a dairy-free option). Stir until smooth and glossy.
- Cool Slightly: Allow the glaze to cool for a few minutes so it thickens slightly but is still pourable.
- Pour the Glaze: Place the cake on a wire rack set over a baking sheet. Slowly pour the chocolate glaze over the top of the cake, letting it drip down the sides. Use a spatula to smooth it out evenly.
- Let the Glaze Set: Allow the cake to sit at room temperature until the glaze sets completely, which can take about 30 minutes.
Easy Keto Sachertorte Variations
Sachertorte can be customized in various ways to suit different preferences or dietary needs. Here are some easy variations that maintain the keto-friendly nature of the dessert.
Nut-Free Keto Sachertorte
For those with nut allergies, replace almond flour with sunflower seed flour or a combination of coconut flour and ground flaxseed. This will give you a similar texture without the use of nuts.
Dairy-Free Keto Sachertorte
Simply swap out the butter for coconut oil and use coconut cream in place of heavy cream to create a dairy-free keto Sachertorte that’s just as rich and satisfying.
Mini Keto Sachertorte
Make individual-sized keto Sachertortes by baking the batter in a muffin tin or mini springform pans. This is perfect for portion control and makes for an elegant presentation.
Tips for Perfecting Keto Sachertorte
Even with the best ingredients, keto baking can sometimes be tricky. Here are a few tips to ensure your Keto Sachertorte turns out perfect every time:
- Watch the Oven Temperature: Keto cakes can overbake quickly. Keep an eye on your cake during the last 10 minutes to avoid drying it out.
- Prevent Crystallization: When using erythritol for the glaze, make sure to whisk it well into the cream to avoid a gritty texture.
- Storage: Store the cake in an airtight container at room temperature for up to 3 days or in the fridge for a week. You can also freeze it, but note that the glaze may lose some of its smoothness upon thawing.

Why Keto Ingredients Make a Difference
Almond Flour vs. Regular Flour
- Almond Flour: Low in carbs and rich in healthy fats, almond flour is a keto-friendly alternative to wheat flour. It provides a moist, dense texture, which is perfect for recreating the traditional texture of Sachertorte.
- Coconut Flour: Though used in smaller quantities, coconut flour absorbs moisture well and can be mixed with almond flour to improve texture and lower the overall calorie content.
Sugar Substitutes vs. Regular Sugar
Keto sweeteners like erythritol, monk fruit, and stevia are all zero-carb alternatives to traditional sugar, which can spike blood sugar levels and knock you out of ketosis. These sweeteners allow you to enjoy dessert without the negative impact on your glucose levels.
Popular Keto Sachertorte Variations
Sachertorte is a versatile dessert that can be adapted to fit various flavor profiles and dietary needs. Here are some popular keto-friendly variations that you can try:
Chocolate-Raspberry Keto Sachertorte
For a fresh twist, replace the apricot jam with sugar-free raspberry preserves. The tartness of the raspberry pairs beautifully with the rich chocolate, offering a delightful contrast in flavors. You can also blend a small amount of fresh raspberries into the sugar-free jam for added texture and a burst of freshness.
Keto Sachertorte Cheesecake
This variation combines two decadent desserts into one! To create a Keto Sachertorte Cheesecake, add a cream cheese layer between the chocolate cake and the sugar-free jam. The creamy texture of the cheesecake enhances the richness of the chocolate and adds a new dimension of flavor.
How to Make It:
- Prepare the cake as usual.
- Make a simple cheesecake filling with cream cheese, heavy cream, and a keto-friendly sweetener.
- Spread the cheesecake layer between the two chocolate cake layers, followed by the jam.
Low-Calorie Keto Sachertorte
If you’re looking to reduce the calorie count of your Keto Sachertorte, there are several modifications you can make:
- Use less butter: Replace some of the butter with Greek yogurt or coconut milk for a lighter texture without sacrificing too much flavor.
- Skip the Glaze: For an even lower-calorie version, omit the chocolate glaze altogether and dust the top with unsweetened cocoa powder instead.
FAQs About Keto Sachertorte
What is the Difference Between Keto Sachertorte and Regular Sachertorte?
The primary difference between keto and regular Sachertorte lies in the ingredients. While the traditional version is made with flour, sugar, and high-carb apricot jam, the keto version uses:
- Almond flour in place of regular flour, which is low in carbs and gluten-free.
- Sugar-free sweeteners such as erythritol or monk fruit instead of sugar.
- Keto-friendly chocolate (85% cocoa or higher) instead of regular dark chocolate, which often contains sugar.
By replacing high-carb ingredients, keto Sachertorte allows you to enjoy the same flavors without spiking your blood sugar or going off track with your keto diet.
Can I Make Keto Sachertorte Without Almond Flour?
Yes, if you are allergic to nuts or prefer not to use almond flour, there are alternatives:
- Sunflower Seed Flour: This can be substituted in equal amounts for almond flour.
- Coconut Flour: Use coconut flour, but remember it is much more absorbent than almond flour, so you’ll need to use it in smaller quantities (typically 1/3 cup of coconut flour replaces 1 cup of almond flour). You may also need to add more eggs or liquid to the batter.
What is the Best Sweetener for Keto Sachertorte?
The best sweetener depends on your personal preference:
- Monk Fruit Sweetener: Popular for its lack of aftertaste and all-natural origins.
- Erythritol: A sugar alcohol that has a mild sweetness and is often blended with other sweeteners for better balance.
- Stevia: A more potent sweetener, ideal for those who prefer a stronger sweet flavor with minimal aftertaste.
Whichever sweetener you choose, ensure that it is keto-approved and has zero to minimal impact on blood sugar.
How Long Can I Store Keto Sachertorte?
Keto Sachertorte can be stored in an airtight container at room temperature for up to 3 days. If you prefer to keep it longer:
- Refrigeration: Store it in the fridge for up to 7 days. Bring the cake to room temperature before serving to soften the texture.
- Freezing: You can freeze Keto Sachertorte for up to 3 months. When ready to serve, thaw it in the fridge overnight and bring it to room temperature before slicing.
Can I Use Other Sugar-Free Jams in Keto Sachertorte?
Yes! The keto version of Sachertorte can be adapted with various types of sugar-free jams, such as:
- Raspberry Jam: Offers a tart flavor that complements the richness of the chocolate.
- Strawberry Jam: A sweeter option, perfect for those who prefer a milder fruity flavor.
- Orange Marmalade: For a more bitter and tangy flavor, sugar-free orange marmalade can add a unique twist.
