For the Mug Cake
• Unsalted Butter – Adds richness and moisture; substitute with coconut oil for a dairy-free version.
• Egg – Provides structure and leavening; ensure it’s beaten well for a light texture.

• Erythritol – A low-carb sweetener that adds sweetness; can replace with any other low-carb sweetener of choice.
• Baking Powder – Helps the mug cake rise; make sure it’s fresh for best results.
• Vanilla Extract – Enhances the flavor profile; opt for pure vanilla for a richer taste.
• Coconut Milk – Adds moisture to the cake; almond milk can be a lower-calorie substitute.
For the Creamy Filling
• Mascarpone Cheese – The main component of the creamy filling; ensure it’s softened for easy mixing.
• Heavy Cream – Contributes to the creamy texture; can replace with a non-dairy whipped topping for a dairy-free option.
For Assembly

• Dark Rum – Adds depth and authenticity; can be omitted or used in lesser amounts according to taste.
• Cocoa Powder – For dusting; use unsweetened cocoa for a classic tiramisu finish.
Step‑by‑Step Instructions for Quick Keto Tiramisu
Step 1: Create the Mug Cake Batter
In a mixing bowl, combine melted unsalted butter, a beaten egg, coconut flour, erythritol, coconut milk, baking powder, and vanilla extract. Whisk these ingredients until you achieve a smooth, lump-free batter. The mixture should be thick yet pourable, giving a soft sheen as it comes together. This delightful base will be the cornerstone of your Quick Keto Tiramisu.
Step 2: Cook the Mug Cakes
Divide the batter evenly into two 3-inch ramekins. Place them in the microwave and cook for about 2 minutes on high power, or until the cakes puff up and spring back when lightly pressed. Once cooked, carefully remove the ramekins from the microwave and allow them to cool slightly before handling, as the ramekins will be hot.
Step 3: Slice the Sponge Layers
Gently turn the mug cakes out onto a cutting board and slice each cake in half lengthwise, creating four sponge layers in total. You want each piece to be even so that they soak up the coffee mixture and layer beautifully in your Quick Keto Tiramisu. Set the layers aside, ready for assembly.
Step 4: Prepare the Creamy Filling
In a separate mixing bowl, whisk together the softened mascarpone cheese, heavy cream, and a bit more powdered erythritol until the mixture is smooth and creamy. The filling should hold soft peaks as you whisk, ensuring a rich and luscious texture that pairs perfectly with your sponge layers for the tiramisu.
Step 5: Mix the Coffee and Rum
In a shallow bowl, combine freshly brewed coffee with dark rum, stirring well. This aromatic mixture will be used to soak the sponge layers, so make sure it’s strong and flavorful, reflecting the classic taste of traditional tiramisu. Adjust sweetness with low-carb sweetener if desired.
Step 6: Assemble the Tiramisu Layers
Dip each sponge layer quickly into the coffee-rum mixture, ensuring they absorb just enough liquid without becoming too soggy. Layer the soaked cakes and mascarpone mixture in your serving glasses, alternating between sponge and cream to create visually appealing layers. Repeat the process until all components are used, building a delicious structure.
Step 7: Finish with Cocoa Dusting and Chill
Once assembled, dust the top of each Quick Keto Tiramisu with unsweetened cocoa powder for a classic finish. Cover the glasses with plastic wrap and chill in the refrigerator for at least 30 minutes. This chilling step allows the flavors to meld beautifully, giving you a dessert that’s both refreshing and indulgent.

Make Ahead Options
These Quick Keto Tiramisu desserts are a delightful choice for meal prep enthusiasts! You can prepare the mug cakes up to 24 hours in advance; simply bake them, let them cool completely, and then store them in an airtight container in the refrigerator. The creamy mascarpone filling can also be made up to 3 days ahead; just whisk the ingredients together and keep them chilled. When you’re ready to serve, assemble the layers by dipping the sponge in the coffee-rum mixture and layering it with the cream. Dust with cocoa powder just before serving for a fresh presentation. This prep-ahead approach saves time and ensures your dessert is just as delicious!

Quick Keto Tiramisu Recipe FAQs
What type of coconut flour should I use for the mug cake?
When making your Quick Keto Tiramisu, opt for finely ground coconut flour. It absorbs moisture differently than other flours, so a little goes a long way. If substituting with almond flour, remember to adjust the liquid in the recipe, as almond flour is less absorbent than coconut flour.
How should I store my leftovers?
Store your Quick Keto Tiramisu in an airtight container in the refrigerator for up to 3 days. It’s best consumed fresh, but the flavors will continue to meld beautifully after a day in the fridge, enhancing the overall taste.
Can I freeze my Quick Keto Tiramisu?
Absolutely! You can freeze assembled servings of the Quick Keto Tiramisu for up to 1 month. Just be sure to wrap them tightly in plastic wrap and then place them in an airtight container to prevent freezer burn. When you’re ready to enjoy it, let it thaw overnight in the refrigerator.
What should I do if my sponge layers are too soggy?
If you find your sponge layers are soggy, it may be due to over-soaking in the coffee mixture. To prevent this, dip the sponge quickly—just a second or two—so they soak up enough flavor without losing their structure. You can also try reducing the soaking time and reducing the amount of liquid in the coffee mix.
Is this recipe allergy-friendly?
This Quick Keto Tiramisu is nut-free, gluten-free, and can be made dairy-free by substituting mascarpone cheese and heavy cream with plant-based alternatives. However, always check ingredient labels, as some sweeteners or dairy-free options may still contain allergens.
Can I make this tiramisu vegan?
Yes! You can create a vegan version by replacing eggs with a flaxseed or chia seed egg substitute (1 tablespoon of ground seeds mixed with 2.5 tablespoons of water, let sit for 5 minutes) and using dairy-free alternatives for both the mascarpone and heavy cream. Just ensure that your sweetener is also vegan-friendly.
