Step‑by‑Step Instructions for Quick Keto Tiramisu
Step 1: Prepare the Sponge Cake
In a microwave-safe bowl, combine the melted unsalted butter, beaten egg, coconut flour, erythritol, baking powder, vanilla extract, and coconut milk. Mix until the batter is smooth and well combined. Pour the batter evenly into two equal-sized ramekins. Microwave the ramekins for 2 minutes, or until the sponge rises and is set. Allow them to cool slightly.
Step 2: Assemble the Filling
In a mixing bowl, whisk together the mascarpone cheese, heavy cream, and powdered erythritol until the mixture is creamy and smooth. Be sure to achieve a light texture, which is essential for the perfect Quick Keto Tiramisu filling. Set this luscious mascarpone cream aside, as it will be layered with the coffee-soaked sponge later.
Step 3: Combine Coffee Mixture
In a shallow bowl, mix your strong coffee with dark rum to create a delightful soaking liquid. Ensure the coffee is warm, as this will help infuse the flavors of the tiramisu. Feel free to adjust the sweetness of the coffee to your preference using low-carb options like erythritol. Set this aside for the assembly process.
Step 4: Layer the Tiramisu
Once the sponge is cool, slice it into even pieces. Dip each sponge slice into the coffee mixture, ensuring each piece is soaked but not soggy. Place the soaked sponge layers into the bottom of your serving glasses or a shallow dish. Then, add a generous layer of the creamy mascarpone mixture over the sponge. Repeat this layering process until all ingredients are used, finishing with the creamy layer on top.
Step 5: Chill (optional)
For the best flavor and texture, chill your assembled Quick Keto Tiramisu in the refrigerator for at least 30 minutes before serving. This allows the flavors to meld beautifully. However, if you’re pressed for time, you can enjoy it immediately. When ready to serve, consider dusting cocoa powder on top for an added touch of richness and visual appeal.

Quick Keto Tiramisu Recipe FAQs
How do I choose the right coconut flour?
When selecting coconut flour, look for a fine, light-colored powder that is free from clumps. Fresh coconut flour should smell mildly sweet and coconutty. Avoid any that has an off or rancid odor. Freshness is key for great texture in your Quick Keto Tiramisu.

To store your Quick Keto Tiramisu, cover it tightly with plastic wrap or transfer it to an airtight container. It can be refrigerated for up to 2-3 days. Make sure to keep it covered to prevent the sponge from drying out, ensuring every bite remains creamy and delicious!

Thaw in the fridge before enjoying for the best experience.
What if my sponge cake turns out dense?
If your sponge is dense, it might be due to overmixing or using stale baking powder. To achieve the airy texture, ensure the egg is beaten to a fluffy consistency before mixing in other ingredients. For freshness, always check your baking powder’s expiration date—it should be active enough to create a rise in your Quick Keto Tiramisu!
Are there any dietary considerations with this recipe?
Yes, this Quick Keto Tiramisu is already gluten-free and suitable for a low-carb diet! If you’re concerned about dairy, feel free to substitute dairy ingredients with suitable alternatives.

Can I adjust the sweetness of the mascarpone layer?
