The Method for Sugar-Free, Keto, Low-Carb Lemon Bars

Step 1: Preheat the Oven
Preheat your oven to 350°F (175°C). This ensures that your lemon bars bake evenly and come out perfectly set.
Step 2: Prepare the Baking Pan
Line a 9×9-inch baking dish with parchment paper, allowing some overhang for easy removal later. This will help you lift the bars out without sticking.
Step 3: Make the Crust
In a mixing bowl, combine the coconut oil and 2 tablespoons of monk fruit sweetener. Use a whisk to mix until combined and creamy. Add in a pinch of salt and sifted coconut flour. Mix until a crumbly dough forms.
Step 4: Press the Crust
Press the dough firmly into the bottom of the lined baking pan. Use your fingers or the bottom of a measuring cup to create an even layer.
Step 5: Bake the Crust
Place the crust in the preheated oven and bake for 15-20 minutes, or until it is lightly golden and firm to the touch. Keep an eye on it to avoid over-baking.
Step 6: Prepare the Filling
While the crust is baking, whisk together the eggs in a separate bowl. Add the remaining 1/2 cup of monk fruit sweetener, lemon zest, and fresh lemon juice. Mix until everything is well combined and smooth.
Step 7: Combine and Pour
Once the crust is done baking, remove it from the oven and let it cool for a few minutes. Pour the lemon filling over the slightly cooled crust, spreading it evenly.
Step 8: Bake Again
Return the baking pan to the oven and bake for an additional 20-25 minutes, or until the filling is set and slightly firm to the touch. A toothpick inserted in the center should come out clean.
Step 9: Cool and Slice
Let the lemon bars cool in the pan for at least 30 minutes. Then, lift them out using the parchment paper and transfer them to a cutting board. Slice into squares and dust with the remaining sifted coconut flour for a beautiful finish.
Customize for Your Needs

- Add key lime zest for a tropical twist.
- For a creamier texture, consider adding a dollop of whipped coconut cream on top.
- Mix in some fresh berries for a fruity variation.
- Top with unsweetened shredded coconut for added texture and flavor.
