Low-Carb Coconut Lime Bars

Step 1
Preheat the oven to 350 degrees F (175 degrees C). Grease an 8-inch square baking dish.

Step 2
Make the crust: Mix almond flour, sweetener, coconut flour, lime zest, and salt in a large bowl together in a large bowl until thoroughly combined. Cut in butter with a fork until combined and no lumps remain. Press crust mixture into the bottom of the prepared baking dish.

Step 3
Bake in the preheated oven until lightly browned, 10 to 15 minutes. Remove from the oven; keep the oven on.

Step 4
Make the filling: Whisk lime juice, coconut milk, sweetener, melted butter, and lime zest in a medium saucepan over medium heat. Mix until sweetener is dissolved; do not let boil. Gradually add beaten eggs, whisking constantly, until mixture is foamy and airy and starts to thicken, 5 to 10 minutes. Remove filling from the heat and spread evenly over the crust.

Step 5
Return to the oven and bake until filling is set in the middle, 10 to 15 minutes.

Step 6
While the bars are baking, make the topping: Toast shredded coconut in a small skillet over medium heat until lightly browned, 2 to 3 minutes. Remove from the heat and toss in lime zest.

Step 7
Remove bars from the oven and sprinkle topping over the surface. Let cool for 15 minutes, then transfer to the refrigerator until chilled, about 2 hours.

Step 8
Cut into 12 bars.
