Keto Key Lime Pie | Low Carb, Creamy & Refreshing Dessert

This Keto Key Lime Pie is delicious, tart, smooth and sweet, and a low-carb way to cool down with a dessert, without knocking yourself out of ketosis. With a silky filling of bright lime flavor, it sits on a buttery crust made with almonds instead of your usual crackerslements (my taste buds are nothing if not adventurous)! While in most recipes sugar and condensed milk add sweetness to this dish, here Keto approved sweeteners and heavy cream are used. So you’re still left with that creamy, dreamy texture and way fewer carbs.

The pie also chills remarkably well if you want to take it to a picnic or serve as a weeknight dessert. It’s also simple to make, but luxurious enough to serve to guests who aren’t keto-friendly. Actually, it’s great for dinner parties or any time you want a sugar free indulgence. Finally, it gets a dollop of whipped cream and lime zest and you won’t believe it didn’t come from a bakery. This pie is not only low carb, it’s like a tropical explosion in your mouth and best of all you get to devour it when you’re into the mood for some healthy indulgence.

Ingredients Equipment Method Notes

Ingredients

  

For the Crust:

• 1½ cups almond flour
• ¼ cup melted butter
• 2 tbsp powdered erythritol
• ½ tsp vanilla extract

For the Filling:

• 1 cup heavy cream
• 4 oz cream cheese, softened
• ½ cup powdered erythritol
• ½ cup fresh key lime juice (or regular lime juice)
• 2 tsp lime zest
• 3 large egg yolks

Equipment

• 1 Mixing bowls
• 1 Hand whisk or electric mixer
• 1 Pie dish (9-inch)
• 1 Measuring Cups & Spoons
• 1 Spatula

Method

 

1. Prepare the Crust: Mix almond flour, butter, erythritol, and vanilla extract together in a bowl until well combined. Press the mixture firmly into a 9-inch pie dish, making an even base. Bake for about 10 minutes at 350°F (175°C). Remove from oven and leave to cool off.
2. Make the Filling: Beat the erythritol eggs until well combined with the softened cream cheese. Blend in lime juice, lime zest, and heavy cream until the filling is soft and smooth.
3. Bake the Pie: Place the filling into the baked crust. Bake at 325°F (160°C) for 15 minutes or until the center rises slightly and begins to firm but is still slightly jiggly.
4. Put It In The Icebox: Allow the pie to cool at room temperature and then chill for at least 2 hours in the refrigerator.
5. Serve it up: top with whipped cream and sprinkle lime zest on top before you cut the first piece.

Notes

• Use fresh key lime juice for the best flavour.
• Don’t over-bake—the filling should have a slight jiggle when removed.
• Chill thoroughly for a firm texture.
• For extra creaminess, fold whipped cream into the filling before baking.
• Add parchment paper under the crust to prevent sticking.
