Ingredients List
For the Keto Crust
- 1 ½ cups almond flour
- ¼ cup melted butter
- 2 tablespoons erythritol or keto sweetener
- ½ teaspoon vanilla extract
- Pinch of salt
For the Key Lime Filling
- 4 large egg yolks
- 1 can (400g) unsweetened condensed coconut milk or keto condensed milk
- ½ cup fresh key lime juice (about 6–8 limes)
- 1 tablespoon lime zest
- ⅓ cup powdered erythritol
- 1 teaspoon vanilla extract
Optional Topping
- 1 cup heavy whipping cream
- 1 tablespoon powdered erythritol
- Extra lime zest for garnish
Step-by-Step Instructions
Step 1: Prepare the Oven
Preheat your oven to 350°F (175°C).
Lightly grease a 9-inch pie pan.
Step 2: Make the Keto Crust
In a mixing bowl, combine:
- Almond flour
- Melted butter
- Sweetener
- Vanilla extract
- Salt
Mix everything until it forms a soft dough.
Press the mixture firmly into the pie pan. Make sure it covers the bottom and slightly goes up the sides.
Bake the crust for 10–12 minutes, until it turns lightly golden.
Let it cool while you prepare the filling.
Step 3: Prepare the Key Lime Filling
In a medium bowl, whisk the egg yolks until smooth.
Add:
- Keto condensed milk
- Fresh key lime juice
- Lime zest
- Sweetener
- Vanilla extract
Whisk everything together until the mixture becomes smooth and creamy.
Tip: Fresh lime juice always gives the best flavor for Keto Key Lime Pie.
Step 4: Fill the Pie
Pour the lime filling into the cooled crust.
Spread it evenly using a spatula.
Step 5: Bake the Pie
Place the pie back into the oven and bake for 15–18 minutes.
The filling should look slightly set but still a little soft in the center.
Remove from the oven and let it cool at room temperature.
Step 6: Chill the Pie
Refrigerate the pie for at least 3 hours.
Chilling helps the filling firm up and improves the flavor.
Step 7: Add the Whipped Cream (Optional)
In a bowl, whip the heavy cream with powdered erythritol until soft peaks form.
Spread or pipe the whipped cream over the pie.
Finish with a sprinkle of lime zest for extra freshness.
Now your delicious Keto Key Lime Pie is ready to enjoy!
