Why I Love This Recipe

There’s something magical about a well-made Key Lime Pie, and this version captures all the tangy goodness with a healthier twist. What I adore about this recipe is how it balances the tartness of fresh lime juice and lime extract with creamy textures that feel indulgent but are actually nourishing. The crust, made from crushed shortbread or low-calorie cookies, adds just the right crunch without loading up on extra calories or butter. I also appreciate how easy it is to customize this pie with gluten-free flour and dairy-free cream cheese if needed, making it accessible to many dietary preferences. This recipe is proof that healthy desserts can be downright delicious and crowd-pleasing.

The Essentials

• 1 1/2 cups crushed shortbread cookies or any low-calorie cookie of choice – forms a crisp yet light crust.
• 1/4 cup allulose – a low-calorie sweetener that keeps this pie sweet without spiking blood sugar.
• 5 tablespoons light butter or light margarine – binds the crust and adds richness.
• 2 cups non-fat Greek yogurt – adds protein and tangy creaminess to the filling.
• 1 cup non-fat cream cheese or dairy-free alternative – makes the filling luxuriously smooth.
• 2 large eggs – help set the filling for that perfect sliceable texture.
• 2/3 cup allulose – sweetens the filling without unnecessary calories.
• 1/4 cup all-purpose flour (gluten-free if needed) – gives structure to the filling.
• 1/4 teaspoon salt – balances flavors and enhances the lime zest.
• 1 tablespoon lime juice – fresh and vibrant, the star of the show.
• 1 teaspoon lime extract (optional) – boosts lime flavor for an extra zing.
• 1 13.5 oz can chilled coconut milk – whipped into a fluffy topping.
• 4 tablespoons sugar-free powdered sugar – sweetens the coconut whipped cream topping.
• 1 teaspoon lime extract (optional) – enhances the whipped cream with a hint of lime.

Must-Have Equipment

• 9-inch pie dish – to shape and bake your pie perfectly.
• Food processor or rolling pin – for crushing the cookies finely.
• Mixing bowls – separate bowls for crust, filling, and topping prep.
• Electric mixer or stand mixer – to whip the filling and coconut cream to dreamy perfection.
• Spatula – for folding ingredients gently.
• Measuring cups and spoons – accuracy matters for balanced flavor and texture.
• Cooling rack – to let your pie rest after baking.

The Method for Healthy Key Lime Pie

Step 1: Prepare the Crust

Crush the shortbread cookies until they’re fine crumbs. You can use a food processor for even texture or place the cookies in a zip-top bag and crush with a rolling pin. In a medium bowl, combine the crushed cookies with 1/4 cup allulose and 5 tablespoons of melted light butter. Mix until the crumbs are evenly coated and hold together when pressed. Press this mixture firmly into the bottom and up the sides of your 9-inch pie dish. Pop it in the fridge while you make the filling.

Step 2: Mix the Filling

In a large bowl, beat together the non-fat cream cheese and Greek yogurt until smooth and creamy using an electric mixer. Add the eggs one at a time, beating well after each addition. Then, mix in 2/3 cup allulose, 1/4 cup flour, and 1/4 teaspoon salt until fully combined. Finally, stir in the fresh lime juice and optional lime extract. The filling should be silky and slightly thick.

Step 3: Bake the Pie

Pour the filling into the chilled crust and smooth the top with a spatula. Bake in a preheated oven at 325°F (163°C) for about 40-45 minutes, or until the filling is set but still slightly jiggly in the center. Once baked, let the pie cool to room temperature before refrigerating for at least 4 hours, preferably overnight. This chilling step helps the pie firm up and develop its signature texture.

Step 4: Make the Coconut Whipped Cream Topping

Chill the can of coconut milk overnight. Scoop the solidified cream into a bowl, leaving the liquid behind. Add 4 tablespoons sugar-free powdered sugar and 1 teaspoon lime extract if desired. Whip with an electric mixer until soft peaks form. Spread or pipe this luscious topping over your chilled pie.

Step 5: Serve and Enjoy

Slice your Healthy Key Lime Pie and serve chilled. Garnish with thin lime slices or zest for an extra pop of color and flavor. This pie is best enjoyed fresh but can be stored for days if you want to savor every bite slowly.

Make It Year-Round

• Use frozen lime juice or bottled lime juice when fresh limes aren’t in season.
• Swap out the lime extract for fresh lemon extract for a twist on the classic.
• Add a sprinkle of toasted coconut flakes on top of the whipped cream for a tropical vibe.
• Turn it into mini pies or tartlets for portion control and party-friendly bites.
• Experiment with different cookie crusts, like crushed graham crackers or almond flour-based crusts.

Watch Outs & How to Fix

If your crust feels too crumbly and won’t stick together, try adding a little more melted butter or pressing it more firmly into the pie dish. For a filling that cracks or overbakes, reduce oven time slightly and check for doneness earlier; the key is to have a slight jiggle in the center when you take it out.

If the coconut milk doesn’t whip properly, ensure it’s thoroughly chilled and only scoop out the solid cream, not the liquid. Adding a teaspoon of cornstarch can help stabilize the whipped cream if needed.

Cooling, Storing & Rewarming

Allow the pie to cool completely at room temperature before refrigerating. Store it in the fridge covered with plastic wrap or in an airtight container for up to 4 days. Since this pie is best served chilled, there’s no need to rewarm it. If you prefer, you can let slices sit out for 10-15 minutes before serving to soften the filling slightly.

Healthy Key Lime Pie Q&A

Can I make this pie dairy-free?

Absolutely! Swap the non-fat cream cheese with a dairy-free cream cheese alternative, and ensure your Greek yogurt is replaced with a plant-based yogurt. The coconut milk whipped topping already fits perfectly into a dairy-free lifestyle.

What if I don’t have allulose? Can I use another sweetener?

Yes, you can substitute allulose with erythritol or monk fruit sweetener, but be mindful that the sweetness level and texture might vary slightly. Regular sugar can be used, but it will increase the calorie count.

Is it possible to make a gluten-free crust?

Definitely! Use gluten-free all-purpose flour in the filling and choose gluten-free cookies or crushed gluten-free graham crackers for the crust. This pie is very adaptable to gluten-free diets.

Can I prepare this pie in advance?

Yes, this pie actually benefits from being made a day ahead. The flavors meld beautifully as it chills, and it’s easier to slice when fully set. Just keep it refrigerated and covered until ready to serve.
