Quick Answer
This key lime pie uses a press-in graham cracker crumb crust instead of a rolled pastry crust, making it the easiest pie in the lineup. The filling is a simple custard of key lime juice, sweetened condensed milk, and egg yolks that sets into a firm, sliceable cream.

Expert Verdict on Gluten-Free Key Lime Pie

Texture Score
9/10 – Premium & Chewy
Moisture Level
high
Common Failure Mistake
The filling doesn't set and is more like a thick liquid than a sliceable pie.
How to Fix It
Make sure you're using enough egg yolks (4) and baking until the filling barely jiggles — the carryover heat finishes the set as it cools.

Gluten-Free Key Lime Pie
Moist texture with no dry bite
Ingredients
- 1 1/2 cups Graham Cracker Crumbs
- 5 tbsp, melted Butter
- 2 tbsp Brown Sugar
- 1/2 cup (about 20 key limes) Key Lime Juice
- 4 yolks Eggs
- 1 tsp Vanilla Extract
- 1 cup, whipped for topping Heavy Cream
- 2 tbsp (for whipped cream) Confectioners Sugar
Instructions
- 1
Preheat oven to 350°F. Mix the graham cracker crumbs, melted butter, and brown sugar. Press firmly into a 9-inch pie dish, including the sides.
- 2
Bake the crust for 8-10 minutes until lightly golden. Set aside to cool.
- 3
Whisk the egg yolks and sweetened condensed milk together until smooth and pale yellow.
- 4
Stir in the key lime juice and vanilla — the mixture will thicken slightly as the acid reacts with the milk proteins.
- 5
Pour the filling into the cooled crust and bake at 350°F for 15-18 minutes until the filling is set but still slightly jiggly in the center.
- 6
Cool completely, then refrigerate for at least 2 hours. Top with whipped cream before serving.
Nutrition Information
Room Temperature Matters
Always bring your eggs and dairy-free alternatives to room temperature before mixing. Cold ingredients create lumps and uneven texture in gluten-free batters.
Don't Skip the Resting Step
Gluten-free flours like almond flour absorb moisture slowly. Let your batter rest for 5–10 minutes before baking for a significantly better crumb structure.
Storage Instructions for Gluten-Free Key Lime Pie
Refrigerate covered for up to 3 days. Add whipped cream just before serving to prevent weeping.
Gluten-Free Key Lime Pie Troubleshooting
Why is my key lime pie filling runny?
Not enough egg yolks to set the custard, or the filling was underbaked.
Use 4 yolks minimum and bake until the edges are fully set and the center barely jiggles.
Why does my crust fall apart when I cut a slice?
The crumb crust wasn't pressed firmly enough or wasn't pre-baked.
Press the crumbs very hard into the dish using the bottom of a measuring cup, and always pre-bake for 8-10 minutes.
