Ingredients
Crust
- 1 1/2 cups almond flour
- 1/2 cup butter (at room temperature or slightly melted)
- 1/4 cup erythritol
- Pinch of salt
- 1/2 teaspoon vanilla extract (optional)
Filling
- 1 cup almond flour
- 1 cup erythritol
- 4 large eggs
- 1/2 cup fresh lemon juice (about 3 lemons)
- Zest of 1 lemon (about 2 tablespoons)
Instructions
- Preheat and prepare crust: Preheat your oven to 350°F (175°C). In a bowl, combine the butter, 1 1/2 cups almond flour, 1/4 cup erythritol, vanilla extract (if using), and a pinch of salt. Mix until a dough forms, then press the mixture evenly into a 9x9-inch baking dish lined with parchment paper. Bake for 15 minutes or until the crust starts to turn golden around the edges.
- Mix the filling: While the crust bakes, in a large bowl, whisk together 1 cup almond flour, 1 cup erythritol, eggs, fresh lemon juice, and lemon zest until the mixture is smooth and free of lumps.
- Bake the lemon bars: Pour the lemon filling evenly over the pre-baked crust. Return the baking dish to the oven and bake for an additional 25 minutes, until the filling is set and slightly firm to the touch.
- Cool and serve: Remove the lemon bars from the oven and allow them to cool at room temperature for at least 30 minutes to fully set. Once cooled, cut into 12 to 16 squares. Optionally, sprinkle with powdered erythritol before serving for an extra touch of sweetness.
Notes
- Ensure the butter is at room temperature or slightly melted to easily combine with almond flour for a uniform crust.
- Use fresh lemon juice and zest for the best vibrant flavor.
- Allow bars to cool completely for cleaner slicing and better texture.
- Store leftovers in the refrigerator for up to 5 days in an airtight container.
- Can be made ahead of time and refrigerated; bring to room temperature before serving for best taste.
