Step‑by‑Step Instructions for Keto Strawberry Tiramisu
Step 1: Prepare Strawberry Sauce
Begin by chopping 1 cup of fresh strawberries and placing them in a saucepan. Add 1 tablespoon of lemon juice and 2 tablespoons of erythritol, along with a splash of water. Heat over medium for about 5 minutes, stirring occasionally until the strawberries are softened and syrupy. Remove from heat and let the sauce cool completely.
Step 2: Make Sponge Cake
Preheat your oven to 350°F (180°C) and line an 8-inch square baking tin with parchment paper. In a mixing bowl, beat together 1/2 cup of softened unsalted butter and 1/2 cup of erythritol until creamy. Next, add 4 egg yolks and 1 teaspoon of vanilla extract, mixing until combined. Gradually add in 1/2 cup of coconut flour, 1 teaspoon of baking powder, and 1/4 teaspoon of salt, mixing until smooth.
Step 3: Incorporate Egg Whites
In a separate bowl, whip 4 egg whites using a hand mixer until stiff peaks form. This will give your sponge cake a light and airy texture. Gently fold the whipped egg whites into the sponge batter using a spatula, being careful not to deflate the mixture. Spoon the batter into the prepared tin, smoothing the top with a spatula, and prepare for baking.
Step 4: Bake
Place the cake tin in the preheated oven and bake for 25 minutes or until the sponge is golden brown and springs back when lightly touched. Once baked, remove from the oven and allow it to cool for 10 minutes in the tin before transferring it to a wire rack to cool completely.
Step 5: Prepare Cream Layer
While the sponge cools, prepare the cream layer. In a mixing bowl, beat together 1 cup of mascarpone cheese and 1 cup of chilled whipping cream until the mixture is thick and smooth. Add in 3 tablespoons of erythritol and 1 teaspoon of vanilla extract, and continue mixing until well incorporated, forming a light and fluffy cream.
Step 6: Assemble Tiramisu
To assemble your Keto Strawberry Tiramisu, spread a layer of strawberry sauce at the bottom of a serving dish. Cut the cooled sponge cake into slices or fingers and arrange them on top of the sauce. Follow with a layer of creamy mascarpone and then sliced strawberries. Repeat the layers, ending with a final layer of cream and topping with additional strawberries for a beautiful finish.
Step 7: Chill
Refrigerate the assembled Keto Strawberry Tiramisu for at least 1 hour to let the flavors meld beautifully. For optimal taste, consider chilling overnight. Once set, slice and serve chilled to enjoy this refreshing summer dessert that combines the best of flavors and textures!

Expert Tips for Keto Strawberry Tiramisu
-
Chill for Flavor: Allow the Keto Strawberry Tiramisu to chill overnight to enhance flavors and help the layers set perfectly.
-
Perfect Egg Whites: Whisk egg whites until stiff peaks form for a light sponge. This is crucial for achieving the desired texture.
-
Quality Cheese Matters: Use mascarpone cheese for creaminess. Avoid substituting with ricotta, as it alters the texture significantly.
-
Avoid Soggy Layers: Layering the sponge quickly can cause it to absorb too much sauce. Enjoy the assembly at a steady pace!
-
Fresh Ingredients: Opt for fresh strawberries when possible; they provide the best flavor and texture for the sauce in your keto tiramisu.
How to Store and Freeze Keto Strawberry Tiramisu
Refrigerator: Keep your Keto Strawberry Tiramisu covered in an airtight container and refrigerate for up to 3 days. It may soften slightly over time but will still be delicious!
Freezer: If you want to enjoy your tiramisu later, freeze it for up to 1 month. Wrap it tightly in plastic wrap, then aluminum foil, to prevent freezer burn.
Thawing: When ready to enjoy, transfer the frozen tiramisu to the refrigerator for about 8 hours or overnight to thaw gently.
Serving Tips: Serve chilled, and give it a chance to rest for a few minutes after thawing for the best flavor and texture!
Make Ahead Options
These Keto Strawberry Tiramisu preparations are perfect for busy home cooks looking to save time! You can make the strawberry sauce up to 3 days in advance; simply refrigerate it in an airtight container to keep it fresh. The sponge cake can also be baked ahead of time—just store it tightly wrapped at room temperature for up to 24 hours or in the fridge for 3 days. When you’re ready to assemble, layer the cooled sponge and strawberry sauce with your prepared cream layer. Just remember to give the assembled tiramisu at least 1 hour in the refrigerator before serving, or chill overnight for the best flavor. This way, you’ll have a restaurant-quality dessert with minimal fuss when it’s time to enjoy it!

Keto Strawberry Tiramisu Recipe FAQs
What type of strawberries should I use for the sauce?
Absolutely! Fresh strawberries work beautifully for this recipe, providing vibrant flavor and natural sweetness. However, if fresh strawberries aren’t available, you can opt for frozen ones. Just ensure to thaw them and drain excess moisture before using to avoid a watery sauce.
How should I store Keto Strawberry Tiramisu?
Very! Keep your Keto Strawberry Tiramisu covered in an airtight container in the refrigerator. It will stay fresh for up to 3 days. If you prefer, you can also freeze it, wrapping it tightly in plastic wrap and then in aluminum foil to prevent freezer burn. This way, it can last up to 1 month!

When you’re ready to enjoy, just let it thaw in the refrigerator for about 8 hours or overnight for the best results.
What if my sponge cake is too dense?
Don’t worry! If your sponge cake turns out too dense, it could be due to overmixing the batter after adding the egg whites. To avoid this, take your time when folding in the whipped egg whites; the key is to be gentle. Remember, the air in those egg whites is what creates a light and airy texture!
Is this dessert suitable for people with nut allergies?
Very! This Keto Strawberry Tiramisu is nut-free since it uses coconut flour instead of traditional flours. However, always double-check the labels of any packaged ingredients you use, like the erythritol and the mascarpone cheese, just in case they are produced in facilities that handle nuts.
Can I use other sweeteners in this recipe?
Absolutely! If you prefer a different low-carb sweetener, you can substitute erythritol with alternatives like stevia or monk fruit sweetener. Just keep in mind the sweetness equivalent, as some sweeteners are sweeter than others; use less if needed, and adjust to taste!
