Ingredients

• 🍋 Fool-Proof Key Lime Pie (Serves 8–10)
• 🛒 Ingredients
• Crust
• 1 1/2 cups graham cracker crumbs (about 10–12 crackers)
• 1/3 cup melted butter
• 3 Tbsp. sugar
• Pinch of salt
• Filling
• 1 can (14 oz.) sweetened condensed milk
• 4 large egg yolks
• 1/2 cup key lime juice
• (fresh or bottled — Nellie & Joe’s works great)
• 1 Tbsp. lime zest (optional but makes it taste homemade)
• Topping
• 1 cup heavy whipping cream
• 2 Tbsp. powdered sugar
• 1/2 tsp. vanilla

Instructions

1. Part 1: Start with making the crust (pre-baking keeps the crust crisp, not soggy):
2. Preheat oven to 350°F.
3. Mix graham crumbs, sugar, salt, and melted butter until it feels like wet sand.
4. Press firmly into a 9-in pie dish (bottom + sides).
5. Bake 8 minutes.
6. Let cool slightly.

8. Part 2: Make the filling (this is the magic part):
9. Whisk egg yolks for about 1 minute until slightly thickened and lighter in color.
10. Add sweetened condensed milk and whisk until smooth.
11. Stir in lime juice and zest.
12. ⚠️ Don’Tbsp. worry — it thickens naturally from the acid reacting with the milk.

14. Part 3: It's time to bake!
15. Pour filling into crust.
16. Bake 15 minutes — just until set but still slightly jiggly in the center. It should NOT brown.

18. Part 4: Now it needs to chill (very important if you want clean slices!)
19. Cool at room temp 30 minutes.
20. Refrigerate at least 4 hours (overnight is best).
21. ---
22. Part 5: Complete with an indulgent whipped-cream topping:
23. Whipping cream, powdered sugar, and vanilla until soft peaks form.
24. Spread or pipe onto pie right before serving.

32. 🔥 Pro tips (makes it taste bakery-level)
33. Use regular limes if key limes are hard to find — nobody can tell.
34. Add a tiny pinch of salt to the filling to boost flavor.
35. Chill overnight if possible — flavor improves a LOT.
