Recipe Ingredients

  • 1 cup finely ground almond flour
  • ¼ cup low-calorie natural sweetener (such as Swerve®)
  • 2 tablespoons coconut flour
  • 1 teaspoon lime zest
  • ¼ teaspoon salt
  • 3 tablespoons butter, softened
  • 1 cup lime juice
  • ½ cup coconut milk
  • ½ cup low-calorie natural powdered sweetener (such as Swerve®)
  • 1 tablespoon butter
  • 1 teaspoon lime zest
  • 5 large eggs, beaten
  • 2 tablespoons unsweetened shredded coconut
  • ½ tablespoon lime zest, or to taste

Cooking Directions

  1. 1 Preheat the oven to 350 degrees F (175 degrees C). Grease an 8x8-inch baking dish.
  2. 2 Combine almond flour, sweetener, coconut flour, lime zest, and salt in a large bowl. Mix thoroughly. Cut in butter with a fork until combined and no lumps remain. Press crust mixture down into the prepared baking dish.
  3. 3 Bake in the preheated oven until lightly browned, 10 to 15 minutes. Set aside.
  4. 4 Whisk lime juice, coconut milk, sweetener, butter, and zest in a medium saucepan over medium heat. Mix until sweetener is dissolved; do not let boil. Add beaten eggs slowly, a little at a time, whisking constantly until mixture is foamy and airy and starts to thicken, 5 to 10 minutes. Remove filling mixture from heat and spread evenly over the crust.
  5. 5 Bake in the preheated oven until filling is set in the middle, 10 to 15 minutes.
  6. 6 Toast shredded coconut in a small skillet over medium heat until lightly browned, 2 to 3 minutes. Sprinkle coconut and lime zest topping over the bars. Let cool and refrigerate completely before cutting into bars.

Chef's Notes

The Allrecipes nutrition calculator doesn't factor in net carbs, so the amount of carbs listed appears higher than what is really in the bars. I used Swerve(R) as the sweetener here, and while it does contain 3 to 4 g of carbs per teaspoon, the ingredients in Swerve do not affect blood sugar, so the carbs it contains are considered non-impact. Because of this, a common practice is to subtract fiber and sugar alcohols from the carb total, making it zero carb. I have calculated the correct carbs for this recipe as 5.1g per serving, not 17.8g; You can use granular sweetener in the filling mixture, though I prefer the powdered version since it dissolves better. You can pulse granular sweetener in a blender or food processor to achieve a powdered consistency. For a sweeter bar, add an additional 1/4 cup of sweetener to the filling mixture; For 1 cup of lime juice, you will need approximately 8 limes.


  1. The only change was monkfruit sweetener, delicious!
  2. Incredibly tart. My husband loves tart but this was too much. We wound up sprinkling a bunch of regular powdered sugar on top to help balance it out. Once we did that it was good.
  3. Methinks the base needs more butter or something to set it. Totally crumbles when trying to bring out as a bar. Also possibly this recipe was written for key limes if they are sweeter than regular? Definitely need to double the sweetener in the custard. I will scoop mine out into a bowl add some - Read more ...
  4. yummy very tasty!
  5. This was amazing. Made it exactly as directed. You should also try since they have the best Keto plan.
  6. Made this 4 times in the last month according to recipe and I enjoy it. The lime flavor is a little bit strong for me.
  7. Recipe developer here!!! I just want to point out a concern that some have with the carb content. I assure you these are keto-friendly. The problem is that the Allrecipes nutrition calculator doesn't factor in NET CARBS so the amount of carbs listed is actually higher than what is really in the bars. I used - Read more ...
  8. So disappointed these are not keto friendly
  9. I haven't made them yet as we are getting ready to move and I did not have coconut flour and coconut milk and thought I'd wait until we get to the new house to stock up on new ingredients.
  10. These would have come out perfect had I remembered to add the sweetener to the custard. I added 1/2 of the sweetener (powdered swerve) to the toasted coconut and lime topping and... well... it made the topping super sweet and after mushing in my mouth with the custard and crust, it was perfect. Mine set - Read more ...
