Recipe Tips
- Use fresh key lime juice for the best flavor; bottled juice works in a pinch.
- Chill the pie long enough for the custard to fully set — at least 3 hours, preferably overnight.
- For a more decorative whipped cream topping, use a piping bag.
- Toasting the graham cracker crumbs slightly before mixing with butter adds extra depth of flavor.
Variations
- Mini Key Lime Pies: Use a muffin tin or small tart pans for individual servings.
- Ginger Graham Crust: Add ½ teaspoon ground ginger to the crust for a subtle spicy note.
- Coconut Whipped Cream: Substitute heavy cream with coconut cream for a tropical twist.
- Chocolate Drizzle: Drizzle melted white or dark chocolate over the whipped cream topping.
- No-Bake Version: Press crust into pan and pour filling; chill without baking crust for a softer base.
Freezing and Storage
- Refrigeration: Store covered in the fridge for up to 3–4 days.
- Freezing: Not recommended with whipped cream topping, as texture may change. Pie without whipped cream can be frozen for up to 1 month.
- Thawing: Thaw overnight in the fridge before serving.
Special Equipment Needed
- 9-inch pie pan
- Medium mixing bowls
- Whisk or electric mixer
- Spatula
- Citrus juicer (optional for fresh lime juice)
