Ingredients:
For the Crust:
- 1 ½ cups almond flour
- ¼ cup coconut flour
- ¼ cup powdered erythritol (or any keto-friendly sweetener)
- ½ cup unsalted butter, melted
- ½ teaspoon vanilla extract
- Pinch of salt
For the Lemon Filling:
- 3 large eggs
- ½ cup powdered erythritol
- ⅓ cup freshly squeezed lemon juice (about 2–3 lemons)
- 1 tablespoon lemon zest (optional, for extra tang)
- ¼ cup coconut flour
- ½ teaspoon baking powder
Topping (optional):
- Extra powdered erythritol for dusting
Instructions:
Step 1: Preheat the Oven
Preheat your oven to 350°F (175°C) and line an 8×8-inch (or 9×9-inch) baking dish with parchment paper, leaving an overhang for easy removal later.
Step 2: Prepare the Crust
- In a medium-sized bowl, combine the almond flour, coconut flour, powdered erythritol, and a pinch of salt.
- Add the melted butter and vanilla extract, stirring until the mixture forms a crumbly dough.
- Press the dough evenly into the prepared baking dish, ensuring it covers the bottom.
- Bake the crust for about 12-15 minutes or until golden brown. Remove from the oven and set aside.
Step 3: Prepare the Lemon Filling
- In another bowl, whisk the eggs and powdered erythritol together until smooth and well-combined.
- Add the lemon juice and lemon zest (if using), mixing thoroughly.
- Sift in the coconut flour and baking powder, stirring until no lumps remain.
Step 4: Bake the Lemon Bars
- Pour the lemon filling over the pre-baked crust, spreading it evenly.
- Return the dish to the oven and bake for 18-20 minutes, or until the filling is set but still slightly jiggly in the center.
- Remove from the oven and allow the bars to cool completely in the pan.
Step 5: Chill and Serve
Once cooled, place the lemon bars in the refrigerator for 1-2 hours to firm up. After chilling, lift them out using the parchment paper overhang, slice into squares, and dust with additional powdered erythritol if desired.
