These soft and creamy keto lemon bars are the treat I turn to when I am craving something bright and silky but want to keep dessert low in carbs. The bars melt in your mouth and come together in a flash making them just right for both family gatherings and weeknight cravings.
I first whipped these up for a potluck with friends who eat gluten free and keto. Everyone was amazed how luscious and zesty they turned out without the sugar.
Ingredients
- Cream cheese: Twelve ounces helps the bars turn out creamy and rich Always use brick style for best results
- Yogurt: One cup adds lightness and tang Full fat gives the best flavor
- Lemon juice: Two tablespoons bring a natural citrus brightness Choose fresh lemon juice for best taste
- Lemon zest: Two teaspoons for intensely lemony flavor Never skip this as it makes all the difference
- Powdered xylitol or erythritol: Half cup keeps it keto and smooth texture Sift if clumpy Use powdered sugar if not worried about carbs
- Almond flour: Three and a half tablespoons thickens the filling and keeps it gluten free For non keto cornstarch can also work
- Turmeric or yellow food coloring: Optional for a hint of sunny color Go with a pinch of turmeric for a natural approach
- Almond flour: One and a half cups forms the base if you want a crust
- Melted butter or coconut oil: Four tablespoons binds the crust and provides rich flavor Look for unsalted butter for best taste
Step-by-Step Instructions
- Prep the Crust:
- Combine almond flour with melted butter or coconut oil in a bowl using a fork until the mixture looks like wet sand Line an eight by eight pan with parchment and firmly press the crust into an even layer Chill as you make the filling
- Blend the Filling:
- In a blender or food processor add cream cheese yogurt lemon juice lemon zest powdered xylitol or erythritol almond flour and turmeric or food coloring Purée until completely smooth and creamy Scrape down the sides to get everything incorporated but avoid over mixing so the filling stays smooth
- Pour and Bake:
- Pour the creamy lemon mixture over the crust and smooth the top Bake at three hundred fifty degrees Fahrenheit for twenty five minutes Keep the oven door closed the whole time for even baking
- Rest in Oven:
- Turn off the oven and let the pan sit inside for eight minutes with the door still closed This gentle finish helps prevent cracking
- Cool and Chill:
- Remove the pan even though the bars will look a little underdone Let them cool fully at room temperature before refrigerating for several hours or overnight This will set the texture for clean slices

My favorite part is adding the lemon zest It gives a punch of real lemon flavor that always reminds me of summers with my grandma in her sunny kitchen zesting lemons side by side
Storage Tips
These lemon bars store beautifully in an airtight container in the fridge for up to four days If you want to keep them longer wrap tightly and freeze for up to one month Be sure to thaw in the fridge for best texture The bars taste even better the next day after the flavors meld
Ingredient Substitutions
No almond flour Swap in sunflower seed flour or very finely ground walnuts for a nut free version For the sweetener use monk fruit if you do not have xylitol or erythritol Dairy free cream cheese and coconut yogurt work seamlessly to keep them plant based
Serving Suggestions
Serve chilled with a dusting of extra powdered sweetener and a few curls of lemon zest I like to pair these with a mug of hot herbal tea or fresh raspberries for a light finish For a party try slicing into small bites for a dessert platter

Cultural Note
Lemon bars are a classic American dessert but this keto version keeps the spirit alive by combining silky cheesecake texture with bright citrus notes Using almond flour for both the crust and filling nods to European traditions of nut based pastries
