3 large eggs
½ cup powdered erythritol
⅓ cup fresh lemon juice
1 tbsp lemon zest
¼ cup heavy cream
2 tbsp almond flour

Instructions

Prep the Crust: Preheat the oven to 350°F (175°C). Line an 8×8-inch baking pan with parchment paper. In a bowl, mix almond flour, melted butter, erythritol, salt, and vanilla until crumbly. Press the mixture firmly into the baking pan.

Bake the Bars: Pour the filling over the partially baked crust. Return the pan to the oven and bake for 15–18 minutes, or until the filling is just set.
