Step-by-Step Instructions

Step 1: Preheat Your Oven

Preheat your oven to 350°F (175°C). Line an 8×8-inch baking pan with parchment paper or lightly grease it.

Step 2: Make the Crust

1. In a mixing bowl, combine the almond flour, sugar-free sweetener, melted coconut oil (or butter), and optional shredded coconut.
2. Press the mixture evenly into the bottom of the prepared pan to form the crust.

Step 3: Bake the Crust

Bake for 10–12 minutes, or until lightly golden. Let the crust cool while you prepare the filling.

Step 4: Prepare the Filling

1. In a mixing bowl, beat the softened cream cheese and sugar-free sweetener until smooth.
2. Add the fresh lime juice, lime zest, and vanilla extract, and mix until fully combined.
3. Gently fold in the sugar-free whipped topping or whipped cream until the mixture is light and airy.

Step 5: Assemble the Bars

1. Pour the lime filling over the cooled crust and spread it evenly.
2. Optional: Sprinkle shredded coconut or additional lime zest on top for garnish.

Step 6: Chill

Refrigerate the bars for at least 4 hours, or until the filling is set.

Step 7: Cut and Serve

Once set, lift the bars out of the pan using the parchment paper and cut them into 9–12 equal-sized bars. Garnish with fresh lime slices if desired.
