Prep Time: 15 minutes
Cook Time: 30 minutes
Total Time: 45 minutes
Servings: 16 squares
Skill Level: Easy
Ingredients
- 2 cups almond flour
- 1/2 cup unsalted butter, melted
- 1/4 cup powdered erythritol
- 1/4 teaspoon salt
- 4 large eggs
- 3/4 cup powdered erythritol (for the filling)
- 1/2 cup lemon juice (freshly squeezed)
- 2 tablespoons lemon zest
- 1/2 teaspoon baking powder
- 2 tablespoons coconut flour
- Powdered erythritol (for dusting)

Instructions
- Preheat your oven to 350°F (175°C). Line an 8×8 inch baking pan with parchment paper, allowing the edges to hang over for easier removal.
- In a medium bowl, combine the almond flour, melted butter, 1/4 cup powdered erythritol, and salt. Mix until well combined and the mixture forms a dough.
- Press the dough evenly into the bottom of the prepared baking pan, forming a crust. Bake for 10-12 minutes, until just lightly golden. Remove from the oven and let it cool while preparing the filling.
- In a large bowl, whisk together the eggs, 3/4 cup powdered erythritol, lemon juice, and lemon zest until smooth and well combined.
- Add the baking powder and coconut flour to the lemon mixture, and whisk until fully incorporated.
- Pour the lemon filling over the crust and spread it out evenly.
- Bake for 25-30 minutes, or until the filling is set and the top is just turning golden.
- Allow the bars to cool completely in the pan before lifting them out using the parchment paper overhang. Cut into 16 squares and dust with powdered erythritol before serving.
Helpful Tips
- For a creamier filling, add a tablespoon of heavy cream to the lemon mixture.
- If you prefer a stronger lemon flavor, increase the lemon zest by 1 extra teaspoon.
- To make the bars ahead of time, store them in an airtight container in the refrigerator for up to 5 days.
Storage Instructions & Substitutions
The Lemon Keto Bars can be stored in an airtight container at room temperature for up to 3 days or in the refrigerator for up to 5 days. For a longer storage option, freeze the bars for up to a month, ensuring they are well-wrapped to prevent freezer burn.
If almond flour is not available, you can substitute with an equal amount of finely ground cashew flour. Coconut flour can be replaced with 1/4 cup more almond flour, but note that the texture may vary slightly.

Pairings
These Lemon Keto Bars pair wonderfully with a freshly brewed cup of herbal tea or a glass of iced green tea. For a delightful combination, serve alongside fresh berries and a scoop of unsweetened whipped cream.
