Prep and Cook Time
- Preparation: 15 minutes
- Baking: 25 minutes
- Cooling: 1 hour (to set properly)
Yield
Approximately 12 generous bars
Difficulty Level
Easy to medium – perfect for bakers seeking a healthy yet delicious challenge
Ingredients
- For the crust:
- 1 ¾ cups blanched almond flour
- ¼ cup powdered erythritol
- ¼ teaspoon fine sea salt
- ½ cup unsalted butter, melted and slightly cooled
- 1 teaspoon pure vanilla extract
- For the lemon filling:
- 4 large eggs, at room temperature
- 1 cup fresh lemon juice (about 4-5 medium lemons), preferably Meyer lemons for a sweeter zest
- ¾ cup powdered erythritol
- ¼ cup coconut flour
- Zest of 2 lemons
- 1 teaspoon baking powder
Instructions
- Prepare the crust: Preheat your oven to 350°F (175°C). In a medium bowl, combine almond flour, powdered erythritol, and sea salt. Stir gently to blend.
- Add butter and vanilla: pour in the melted butter and vanilla extract. Mix thoroughly with a spatula until the mixture resembles wet sand and holds together when pressed.
- Press and bake: Line an 8×8-inch baking pan with parchment paper, leaving overhang for easy removal. Press the crust mixture evenly and firmly into the bottom. bake for 12-15 minutes until golden around the edges but not browned. Remove from oven and allow cooling slightly.
- Mix the filling: While the crust cools, whisk together eggs, fresh lemon juice, lemon zest, powdered erythritol, coconut flour, and baking powder until smooth and slightly thickened.
- Pour and bake again: Pour the lemon filling evenly over the warm crust. return the pan to the oven and bake for an additional 15 minutes or until the filling is set and no longer jiggles.
- Cool and chill: Remove from oven and let cool to room temperature. Refrigerate for at least 1 hour to allow the bars to firm up perfectly. This step is crucial for that clean slice and delightful texture.
- Slice and serve: use the parchment overhang to lift the bars from the pan. Cut into 12 squares with a sharp knife, wiping the blade between cuts for crisp lines.
Tips for Success
- For maximum zest,use Meyer lemons if you can find them-thay soften the acidity with a subtle sweetness.
- Don’t skip chilling; refrigeration firms the lemon filling for clean slicing and mellows the flavors.
- If the crust feels too soft after baking,a tablespoon more almond flour mixed in before pressing helps add structure.
- swap erythritol for monk fruit sweetener to reduce any cooling aftertaste, if preferred.
- Use room temperature eggs to ensure a smooth lemon filling without curdling.
