What Makes This Key Lime Pie So Special?

Key Ingredients and Their Role

• Graham Cracker Crumbs: These form the sweet, crunchy base that supports the creamy filling.
• Brown Sugar: Adds a caramel note and helps bind the crust together.
• Unsalted Butter: Gives the crust its richness and holds everything in place.
• Sweetened Condensed Milk: Provides sweetness and ensures the filling sets without eggs.
• Plain Greek Yogurt: Adds a creamy, tangy finish and helps with the pie’s structure.
• Lime Zest: Delivers bold citrus aroma and flavor.
• Fresh Lime Juice: The star ingredient that defines any true Key Lime Pie.
• Heavy Cream: Whipped for a soft, airy topping.
• Confectioners’ Sugar: Gently sweetens the whipped cream without leaving any grit.
• Lime Slices and Extra Zest: For garnish and added visual appeal.

Ingredient Swaps You Can Try

• Gluten-Free Option: Use gluten-free graham crackers for a wheat-free crust.
• Non-Dairy Yogurt: Try coconut-based yogurt for a vegan twist.
• Bottled Lime Juice: If you’re short on fresh limes, high-quality bottled Key lime juice can work.
• Coconut Cream Topping: For a dairy-free whipped topping, chill canned coconut cream and beat until fluffy.

How to Make This Easy Key Lime Pie

Prepare the Crust
Preheat your oven to 375°F. In a mixing bowl, combine graham cracker crumbs, brown sugar, and melted butter. Mix until the crumbs are moist and evenly coated. Press the mixture firmly into a 9-inch deep-dish pie pan using a flat-bottomed glass. Bake for 10 minutes until lightly golden. Let the crust cool while you prepare the filling.
Make the Filling
Lower the oven temperature to 350°F. In a large bowl, whisk together sweetened condensed milk, Greek yogurt, lime zest, and lime juice. The mixture should be thick and creamy. Pour the filling into the baked crust and smooth the top.
Bake and Cool the Pie
Bake the pie for 15 minutes. The filling should jiggle slightly but not appear liquid. Let the pie cool at room temperature for 30 minutes. Then transfer it to the refrigerator for at least 3 hours to fully set.
Prepare the Whipped Topping
In a chilled mixing bowl, beat heavy cream until soft peaks form. Add confectioners’ sugar and continue beating until medium peaks form. Spread the whipped cream over the cold pie. Finally, garnish with lime zest and slices.

Expert Tips for Success

• Zest First: Always zest the limes before juicing them. It’s difficult to do this in reverse.
• Use Room-Temperature Ingredients: This ensures smoother blending and even baking.
• Check the Jiggle: The center should wobble slightly when the pie is done—this means it’s set but still creamy.
• Chill Fully: Let the pie rest in the fridge to achieve a firm, sliceable consistency.
• Clean Your Knife: Wipe the knife between each slice for neat presentation.

Delicious Pairings and Creative Twists

• Toppings: Sprinkle toasted coconut or crushed graham crackers for added texture.
• Fruit Additions: Fresh berries make a colorful and tart counterpoint to the lime filling.
• Crust Variations: Try a cookie crust using vanilla wafers or gingersnaps for added flavor.
• Mini Pies: Use muffin tins to make individual servings—great for parties.
• Make-Ahead Note: Bake the crust a day ahead. Add the filling on the day you plan to serve it to prevent sogginess.
