Instructions Checklist
  • Preheat the oven to 350 degrees F (175 degrees C). Grease an 8x8-inch baking dish.

  • 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.

  • Bake in the preheated oven until lightly browned, 10 to 15 minutes. Set aside.

  • 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.

  • Bake in the preheated oven until filling is set in the middle, 10 to 15 minutes.

  • 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.

Cook'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.
