Frequently Asked Questions
Can I use a different type of flour for the crust?
Almond flour is the best low-carb option and provides a buttery, shortbread-like texture. Coconut flour cannot be substituted directly because it’s far more absorbent. If you must use coconut flour, use only ⅓ cup and increase the butter to 5 tablespoons, but the crust will be more crumbly and have a distinct coconut flavor. A blend of almond flour and finely ground pecans also works well.
Why did my filling crack?
Cracks usually happen when the filling is overbaked, beaten with too much air, or cooled too quickly. Make sure to bake just until the center jiggles slightly, don’t overbeat the eggs, and let the pan cool gradually on the counter before refrigerating. If cracks do appear, they’re purely cosmetic; a dusting of powdered sweetener covers them beautifully.
Is this recipe dairy-free?
As written, no, it contains butter, cream cheese, and heavy cream. For a dairy-free version, use a plant-based butter or coconut oil for the crust, dairy-free cream cheese, and full-fat coconut cream (the solid part from a chilled can). The flavor and texture will be slightly different but still delicious.
Can I use bottled lemon juice?
Fresh lemon juice is strongly recommended for the bright, zesty flavor that defines these squares. Bottled juice often has a flat, slightly metallic taste. If you must use bottled, opt for a high-quality brand, but the fresh version is truly worth the extra squeeze.
My squares are too soft to slice cleanly—what did I do wrong?
They likely need more chilling time. The filling sets firmly only when fully cold. Ensure you refrigerate for at least 4 hours, and preferably overnight. Also, check that you used full-fat cream cheese, as low-fat versions contain more water and may not set as firmly. If they’re still soft, you can pop them in the freezer for 30 minutes before slicing for extra firmness.

Prep Time:
20 minutes
Cook Time:
32–40 minutes
Chill Time:
4 hours (or overnight)
Total Time:
About 5 hours
Yield:
16 squares
Ingredients
For the Crust:
- 1½ cups super-fine blanched almond flour
- ¼ cup unsalted butter, melted
- 2 tablespoons powdered keto sweetener (such as Swerve Confectioners or monk fruit powdered)
For the Filling:
- 8 oz full-fat cream cheese, softened
- 6 tablespoons powdered keto sweetener (in addition to the crust sweetener)
- Zest of 2 lemons
- 2 large eggs, room temperature
- ¼ cup heavy whipping cream
- ⅓ cup fresh lemon juice (from about 2–3 lemons)
- 1 teaspoon vanilla extract
- Pinch of salt
For Garnish (Optional):
- Powdered keto sweetener, for dusting
- Lemon zest or thin lemon slices
- Fresh berries
Instructions
- Preheat oven to 350°F (175°C). Line an 8×8-inch square pan with parchment paper and lightly grease.
- Make the crust: In a bowl, mix almond flour, melted butter, and 2 tablespoons powdered sweetener until it resembles damp sand. Press firmly into the pan. Bake for 10–12 minutes until edges are lightly golden. Remove and keep oven on.
- Make the filling: In a large bowl, beat the cream cheese until smooth. Add the 6 tablespoons powdered sweetener and lemon zest; beat until combined. Add eggs one at a time, mixing on low just until incorporated. Mix in heavy cream, lemon juice, vanilla, and salt until smooth.
- Pour the filling over the pre-baked crust and spread evenly. Gently tap the pan on the counter to release air bubbles.
- Bake for 22–28 minutes, until the edges are set and the center has a slight jiggle. The filling will set fully as it cools.
- Cool the pan on a wire rack to room temperature, about 1 hour. Then refrigerate for at least 4 hours, preferably overnight, until fully chilled and firm.
- Slice into 16 squares using a sharp knife, wiping clean between cuts. Dust with powdered sweetener and garnish with lemon zest or berries before serving. Keep refrigerated.
Notes
- Use powdered sweetener for a smooth, non-gritty texture. Granular sweetener will not dissolve and will leave a crunchy mouthfeel.
- The filling will be soft when warm; chilling is necessary for clean slices. Overnight chilling gives the best flavor and texture.
- For a dairy-free version, use plant-based butter, dairy-free cream cheese, and coconut cream. The texture will vary.
- Store covered in the refrigerator for up to 5 days, or freeze for up to 3 months.
