If you are a lover of lemon then these Keto Lemon Bars are perfect for you! Made with a buttery almond flour crust, then topped with delicious low carb lemon curd, these easy and healthy sugar-free lemon bars are going to be a hit in your household.




  • 1 ½ cups almond flour
  • 1 egg
  • ¼ tsp salt
  • ¼ cup melted butter
  • ¼ cup granulated monk fruit


  • ½ cup granulated monk fruit
  • ½ cup powdered swerve
  • ¼ cup almond flour
  • 4 eggs 
  • 1 tbsp lemon zest
  • ½ cup lemon juice
  • ½ tsp vanilla 


  • powdered swerve for dusting 




Use a glass dish. Metal pans can cause the lemon squares to have a slightly metallic taste.

Fresh lemon juice – Bottled lemon juice doesn’t even come close to the real thing.

Lemon zest is also key, it adds another level of lemony flavor. 

Line the baking dish with parchment paper so you can easily pull it out. 

When cutting the squares, wipe the knife with a paper towel or rinse with hot water in between cuts. 

Double the recipe – use a 9×13 baking dish and double all the ingredients.  

Make sure the bars are completely cooled before cutting into them. 

Add the powdered sugar after the bars are cut into squares.
