Step‑by‑Step Instructions for Keto Strawberry Tiramisu
Step 1: Prepare Strawberry Sauce
In a medium saucepan, combine chopped strawberries, lemon juice, erythritol, and water. Cook over medium heat for 5 minutes until the strawberries soften and release their juices. Stir occasionally to prevent sticking. Once done, remove from heat and allow the mixture to cool completely, thickening into a delicious sauce that will elevate your Keto Strawberry Tiramisu.
Step 2: Preheat Oven
While the strawberry sauce cools, preheat your oven to 180°C (350°F). Prepare an 8-inch square baking tin by lining it with parchment paper, ensuring that the paper hangs over the sides for easy removal later. This will support a perfectly baked sponge cake that forms the foundation of your delightful Keto Strawberry Tiramisu.
Step 3: Make Sponge Cake
In a large mixing bowl, whisk together softened butter and erythritol until the mixture is light and creamy. Add in the egg yolks and vanilla extract, mixing until fully incorporated. Gradually incorporate coconut flour, salt, and baking powder, stirring until smooth. Adjust the consistency with a little water if the batter becomes too stiff, making sure it’s pourable for your cake.
Step 4: Whip Egg Whites
In a separate clean bowl, beat the egg whites using an electric mixer until they reach stiff peaks. This step is crucial for achieving a light and airy sponge cake. Once whipped to perfection, gently fold the egg whites into the butter mixture using a spatula, being careful not to deflate the airy texture you’ve created.
Step 5: Bake Cake
Pour the prepared batter into your lined baking tin, spreading it evenly. Bake in the preheated oven for about 25 minutes or until the cake is golden brown and firm to the touch. Once baked, remove it from the oven and let it cool on a wire rack. This cooling process is essential for the next layering steps in your Keto Strawberry Tiramisu.
Step 6: Prepare Cream Layer
In a mixing bowl, beat together mascarpone and whipping cream until smooth and creamy. Slowly add the erythritol and vanilla extract, mixing until fully combined and fluffy. This luscious cream layer is critical as it balances the tartness of the strawberry sauce and serves as a dreamy topping for your Keto Strawberry Tiramisu.
Step 7: Assemble Dessert
In a baking dish, begin layering by first adding a layer of cooled strawberry sauce. Follow with a layer of chopped sponge cake, then spread some of the creamy mascarpone mixture on top. Repeat these layers until the dish is full, making sure to finish with a beautiful cream layer topped with fresh strawberry slices for that extra summer touch.
Step 8: Chill
Cover your assembled Keto Strawberry Tiramisu with plastic wrap or a lid, and refrigerate for at least 1 hour to allow the flavors to meld together. This chilling step is essential for setting the dessert and enhancing its flavors, making your summer treat even more delightful when it’s time to serve.

Expert Tips for Keto Strawberry Tiramisu

What should I do if my sponge cake doesn’t rise properly?
If your sponge cake doesn’t rise, it might be due to under-whipped egg whites or old baking powder.
