Prep and Cook Time
Readiness: 20 minutes | Cooking: 30 minutes | Cooling: 1 hour
Yield
12 generous bars
Difficulty Level
Easy – perfect for beginners and seasoned bakers alike
Ingredients
- For the crust:
- 1 ¾ cups almond flour, finely ground
- 2 tbsp coconut flour
- ¼ cup powdered erythritol
- ½ tsp baking powder
- ½ tsp sea salt
- 6 tbsp unsalted butter, melted
- 1 tsp vanilla extract
- For the lemon filling:
- 4 large fresh lemons, zested and juiced (about ½ cup juice)
- 4 large eggs, room temperature
- ¾ cup powdered erythritol
- ¼ cup heavy cream
- 2 tbsp coconut flour
Instructions
- Preheat your oven to 350°F (175°C). Lightly grease an 8×8 inch baking pan and line it with parchment paper, allowing extra on two sides for easy bar removal.
- Prepare the crust: In a medium bowl, whisk together almond flour, coconut flour, powdered erythritol, baking powder, and salt. Stir in the melted butter and vanilla extract untill the mixture becomes crumbly but holds together when pressed.
- Press the crust mixture firmly and evenly into the bottom of the prepared pan. Use the back of a spoon or the bottom of a glass for a smooth finish to create a compact base.
- Bake the crust for 12-15 minutes or until golden and fragrant. Allow it to cool slightly while preparing the filling.
- Make the filling: In a mixing bowl, whisk eggs until frothy. Add lemon zest, lemon juice, powdered erythritol, heavy cream, and coconut flour. Whisk thoroughly until the batter is smooth and glossy.
- Pour the filling over the warm crust and gently smooth the surface with a spatula.
- Bake for 18-20 minutes, or until the filling is set but still slightly jiggly in the center. Avoid overbaking to maintain the creamy texture.
- Cool fully at room temperature, then transfer to the refrigerator for at least 1 hour to fully firm up and enhance the zesty flavor.
- Slice into bars using a sharp knife dipped in hot water between cuts to achieve clean edges.
Tips for Success
- Fresh lemons are essential-not only for juice but also for rind zest that brings that unforgettable zing.
- Using powdered erythritol instead of granulated prevents a grainy texture in both crust and filling.
- Don’t overbake the lemon filling; it should retain a slight wobble for a silky finish once chilled.
- For a dairy-free version, substitute butter with coconut oil and heavy cream with full-fat coconut milk.
- Make ahead transportation ease by storing in a sealed airtight container-these bars stay fresh for up to 5 days refrigerated and can be frozen for up to 3 months.
Serving Suggestions
Elevate presentation by dusting the lemon bars lightly with powdered erythritol or garnishing with thin lemon slices and fresh mint sprigs.Pairing these bars with a cup of herbal tea or a keto-friendly sparkling water with a citrus twist intensifies their refreshing profile. Serve chilled for the ultimate cool, tangy bite that complements warm weather and festive occasions alike.
