For the Lemon Curd:
- 3 large eggs
- 1/2 cup granulated keto-friendly sweetener (e.g., erythritol, stevia)
- Zest of 2 lemons
- 1/2 cup fresh lemon juice
- 1/4 cup unsalted butter, cubed
For the Tiramisu Layers:
- 1 cup heavy whipping cream
- 8 oz mascarpone cheese
- 1 teaspoon vanilla extract
- 1/4 cup granulated keto-friendly sweetener
- 1 package of keto-friendly ladyfinger-style cookies (you can use almond flour-based ones)
- Strong brewed coffee or espresso, cooled
- Unsweetened cocoa powder, for dusting
- Prepare the Lemon Curd:
- In a heatproof bowl, whisk together the eggs and sweetener until well combined.
- Place the bowl over a pot of simmering water (double boiler) and add lemon zest, lemon juice, and butter.
- Whisk continuously until the mixture thickens and coats the back of a spoon, similar to a custard. This should take about 10-15 minutes.
- Remove from heat and let it cool. Cover with plastic wrap directly touching the curd’s surface to prevent a skin from forming. Refrigerate until cold.
- Prepare the Tiramisu Filling:
- In a mixing bowl, beat the heavy whipping cream until stiff peaks form. Set aside.
- In another bowl, whisk together the mascarpone cheese, vanilla extract, and sweetener until smooth.
- Gently fold the whipped cream into the mascarpone mixture until well combined.
- Assemble the Tiramisu:
- Dip the ladyfinger-style cookies into the cooled brewed coffee or espresso one at a time, making sure not to soak them too much. Arrange a layer of dipped cookies in the bottom of a serving dish.
- Spread a layer of the mascarpone mixture over the cookies.
- Drizzle a layer of lemon curd over the mascarpone mixture.
- Repeat the layers:
- Add another layer of dipped cookies.
- Spread another layer of the mascarpone mixture.
- Drizzle another layer of lemon curd.
- Dust the top of the tiramisu with unsweetened cocoa powder.
- Cover the dish with plastic wrap and refrigerate for at least 4 hours, preferably overnight, to allow the flavors to meld and the dessert to set.
- Cut into portions and serve chilled.
