How to Make Keto Lemon Bar Cookies
-
Preheat the oven to 325°F and prep your mini muffin pan with silicone liners. This step ensures your cookie cups come out easily without sticking.
-
Whisk together the almond flour, Swerve Granular, baking powder, and salt in a large bowl. Once blended, stir in the melted butter, egg white, and vanilla extract until a cohesive dough forms.
-
Roll the dough into scant 1-inch balls and place them in the prepared muffin cups. Bake for 5 minutes as is; then, remove from the oven and gently press a deep well into the center of each ball for the curd.
-
Bake again for 10 to 12 minutes until the cookie edges are lightly golden. Allow them to cool completely in the pan—reshape any puffed wells while still warm, then pop out of the molds.
-
Cook the lemon curd by whisking the egg, egg yolk, powdered sweetener, lemon juice, and zest in a bowl set over barely simmering water. Keep whisking until thickened, about 10 minutes.
-
Finish the curd by removing it from heat and adding the butter. Allow it to melt then whisk until you achieve a smooth and creamy texture—let sit for 15 minutes to cool.
-
Spoon the luscious lemon curd into each cookie cup, filling them up to the brim. Refrigerate for at least 1 hour to firm up, then dust with additional powdered sweetener before serving.
Optional: Garnish with a sprinkle of lemon zest for an extra burst of flavor.

Tips for the Best Keto Lemon Bar Cookies
- Chill the Dough: Allowing the dough to rest in the refrigerator for about 15 minutes can make it easier to roll into balls and help them hold their shape while baking.
- Avoid Overbaking: Keep an eye on the cookie cups as they bake; removing them just when the edges start to brown will ensure a tender, melt-in-your-mouth texture.
- Perfect Curd Consistency: Whisk continuously while making the lemon curd to prevent it from curdling; patience is key to achieving that silky smooth finish.
- Reshape While Warm: If the wells puff slightly during baking, gently reshape them using your thumb or a rounded tool while the cookies are still warm for that perfect curd-holding indentation.
- Serving Suggestions: These delicious Keto Lemon Bar Cookies are best served chilled; refrigerating them helps the flavors meld beautifully, enhancing your overall experience.
With these expert tips, you’ll nail the perfect batch of Keto Lemon Bar Cookies every time!

Keto Lemon Bar Cookies Recipe FAQs
What type of almond flour should I use for the cookie cups?
I recommend using blanched almond flour for the smoothest texture and best flavor in your Keto Lemon Bar Cookies. It has a finer grind compared to raw almond flour, which can yield a grainier result. Make sure to check for any additives to ensure it’s keto-friendly.
How should I store leftover cookie cups?
Store your cookie cups in an airtight container in the fridge for up to 3 days. This helps retain their freshness and lets the flavors meld deliciously. If you notice any moisture, consider layering paper towels between the cookies to maintain texture.
Can I freeze Keto Lemon Bar Cookies?
Absolutely! To freeze, place the filled cookie cups in a single layer on a baking sheet until they are solid, about 1-2 hours. Then, transfer them to a freezer bag. They can last up to 2 months in the freezer. When you’re ready to enjoy them, thaw them in the fridge overnight or at room temperature for a couple of hours before serving.
What can I do if my lemon curd doesn’t thicken?
If your lemon curd isn’t thickening, make sure you’re whisking continuously during the heating process. It can take around 10 minutes for the mixture to reach the right consistency. If it still doesn’t thicken after this time, you can add a bit more egg yolk (after whisking it) and return it to the heat to help it set properly. Be patient, as achieving that silky texture is worth it!
Are these cookies suitable for people with nut allergies?
Since these Keto Lemon Bar Cookies are made with almond flour, they are not suitable for those with nut allergies. However, you can experiment with other low-carb flour alternatives like sunflower seed flour, though the flavor and texture may vary slightly. Just be sure to maintain the right ratios for your new substitute!
