Imagine the zing of fresh limes on a warm summer day, with each bite taking you closer to that perfect balance of tart and sweet.
Steps
- Prepare the Condensed Milk: Begin by making the sugar-free condensed milk ahead of time, allowing it to cool completely. It’s advisable to prepare it the day before and store it in the refrigerator overnight to thicken.
- Make the Crust: Preheat your oven to 325°F. In a large bowl, combine almond flour, a brown sugar substitute, cinnamon, and salt. Stir in melted butter until well-mixed, then press the mixture into a pie plate, shaping it along the bottom and sides.
- Bake the Crust: Place the crust in the oven and bake for about 12 minutes until it starts to brown at the edges. Remove from the oven and let it cool completely before adding the filling.
- Prepare the Filling: In another bowl, beat egg yolks with lime zest until they thicken and become paler. Add in the prepared condensed milk and continue beating until the volume increases, then mix in lime juice and powdered sweetener.
- Assemble the Pie: Pour the lime filling into the cooled pie crust. Cover the pie with foil and bake at 325°F for 30 minutes, then remove the foil and bake for an additional 10 minutes. The filling should be set around the edges but slightly jiggly in the center.
- Chill the Pie: Allow the pie to cool completely at room temperature, then refrigerate for at least 2 to 3 hours to ensure it sets properly.

FAQ
- Can I substitute regular limes for key limes in this recipe?
- Yes, you can use regular Persian limes instead of key limes. They are easier to juice and work just as well in this recipe.
- Is it possible to use a different sweetener for the keto key lime pie?
- You can substitute different sweeteners, but keep in mind that only erythritol-based sweeteners will ensure a crisp crust. For the condensed milk, using BochaSweet or allulose helps prevent recrystallization.
- Can this keto key lime pie be made without dairy?
- Yes, you can make the pie dairy-free. Substitute coconut cream for the heavy whipping cream in the condensed milk, and use coconut oil or another non-dairy butter alternative for the crust.
- How should I store the keto key lime pie?
- Since it is custard-based, the pie should be stored in the refrigerator and will remain fresh for up to five days. It is not recommended to freeze this pie as the filling may alter in texture.
Tips
- Make the Condensed Milk Ahead: Prepare the sugar-free condensed milk in advance, ideally the day before, so it has time to cool completely. This allows it to thicken in the refrigerator and be ready for use when needed.
- Simplify the Crust: Instead of making graham crackers only to crumble them later, mix the crust ingredients directly and press them into the pan. This saves time and effort while maintaining the traditional graham cracker taste.
- Par-Bake the Crust: Bake the crust for about 12 minutes before adding the filling. This step helps ensure the crust is well set and supports the pie filling effectively.
- Cover While Baking: Use foil to cover the pie during the initial 30 minutes of baking. This prevents the crust from over-browning while ensuring the filling cooks properly.
