Ingredients

• For the Gluten-Free Graham Cracker Crust
• 1 ½ cups (about 180g) gluten-free graham cracker crumbs: It's crucial these are certified GF. You can crush whole gluten-free graham crackers yourself or buy pre-crushed crumbs.
• 6 tablespoons (85g) unsalted butter, melted: Or use melted dairy-free butter alternative for a dairy-free option.
• ¼ cup (50g) granulated sugar
• ½ teaspoon ground cinnamon
• Pinch of salt
• Short note: Gluten-free crumbs lack the gluten structure of traditional graham crackers, so a precise fat-to-crumb ratio and firm pressing technique are key to a crust that holds together. An ideal pan is a 9-inch pie plate; using a deeper dish might result in a thinner crust.
• For the Vanilla Custard Filling
• 2 cups (480ml) whole milk: Or at least 2% milk for the best, creamiest set.
• 4 large egg yolks
• ½ cup (100g) granulated sugar
• 3 tablespoons (24g) cornstarch: Naturally gluten free, but always double-check labels for certification.
• 1 teaspoon pure vanilla extract
• Pinch of salt
• For the Meringue Topping
• 4 large egg whites (at room temperature)
• ½ cup (100g) granulated sugar
• ¼ teaspoon cream of tartar: Or ¼ teaspoon lemon juice as an alternative.
• Optional: ¼ teaspoon vanilla extract or a tiny dash of almond extract for extra flavor.

Directions

1. Make and Bake the Gluten-Free Graham Cracker Crust
2. Prepare the Crumbs: If starting with whole gluten-free graham crackers, crush them finely. A food processor works best for even crumbs, but you can also place them in a zip-top bag and crush with a rolling pin. You're aiming for fine, sandy crumbs, not chunky pieces.
3. Combine Ingredients: In a medium bowl, mix the gluten-free graham cracker crumbs, sugar, cinnamon, and salt. Pour in the melted butter and stir until everything is evenly moistened and resembles wet sand.
4. Press into Pan: Transfer the crumb mixture to a 9-inch pie plate. Use the bottom of a measuring cup or a flat-bottomed glass to firmly press the mixture onto the bottom and up the sides of the pie plate. Be sure to press firmly and evenly to avoid any thin spots that could crumble later.
5. Bake the Crust: Bake in a preheated oven at 350°F (175°C) for 8-10 minutes, or until the edges are lightly golden and fragrant. Remove from the oven and let it cool slightly while you prepare the filling.
6. Inline note for pre-made or mix crusts:
7. Using a store-bought gluten-free pre made pie crust or a gluten-free pie crust mix? Simply pre-bake it as directed on the package, let it cool completely, and then skip straight to Step 3 for the custard filling.
8. Cook the Vanilla Custard Filling
9. Whisk Dry Ingredients: In a medium saucepan (off the heat), whisk together the ½ cup sugar, cornstarch, and pinch of salt.
10. Temper Egg Yolks: In a separate small bowl, whisk the egg yolks. Warm the milk gently in a microwave or small saucepan until it's steamy but not boiling. Slowly drizzle about half of the warm milk into the whisked egg yolks, whisking constantly to temper them (this prevents the eggs from scrambling).
11. Combine & Cook: Pour the tempered yolk mixture back into the saucepan with the remaining milk and dry ingredients. Whisk everything together until smooth. Place the saucepan over medium heat and cook, stirring constantly with a whisk or rubber spatula, until the mixture thickens significantly, bubbles gently, and coats the back of a spoon. You should be able to draw a visible trail with your whisk. This usually takes about 8-12 minutes.
12. Finish Custard: Remove the saucepan from the heat. Stir in the vanilla extract. Let the custard cool for a few minutes in the pan, stirring occasionally, to prevent it from melting the crust when poured in.
13. Whip the Meringue
14. Prepare for Meringue: Ensure your mixing bowl (preferably glass or metal) and beaters are absolutely spotless and free of any grease or fat. Even a tiny speck can prevent the egg whites from whipping properly.
15. Whip Whites: In the clean bowl, beat the egg whites with the cream of tartar (or lemon juice) on medium speed until soft peaks form. This means when you lift the beaters, the peaks gently flop over.
16. Add Sugar: With the mixer still running on medium speed, slowly stream in the ½ cup of granulated sugar, a tablespoon at a time. Continue beating on medium-high speed until the meringue is glossy, thick, and forms stiff peaks. Stiff peaks will hold their shape firmly when the beaters are lifted and have a shiny appearance. Be careful not to over-beat, which can make the meringue grainy or clumpy. If using, gently fold in the optional vanilla or almond extract.
17. Assemble & Bake
18. Fill the Crust: Pour the warm (not boiling hot) vanilla custard into the slightly cooled gluten-free graham cracker crust.
19. Top with Meringue: Carefully spread the whipped meringue over the hot custard, making sure to seal the meringue all the way to the edges of the crust. This helps prevent the meringue from shrinking or "weeping" during baking.
20. Optional Garnish: If desired, sprinkle a spoonful of reserved gluten-free graham cracker crumbs over the top of the meringue for a decorative touch.
21. Bake to Perfection: Bake the pie in a preheated oven at 350°F (175°C) for 15-20 minutes, or until the meringue is beautifully golden brown and set. Keep a close eye on it, as meringue can brown quickly.
22. Cool, Chill & Slice
23. Cool Gradually: Once baked, remove the pie from the oven and let it cool completely at room temperature, away from drafts, for at least 1-2 hours.
24. Chill Thoroughly: Once barely warm, transfer the pie to the refrigerator and chill for at least 4 hours, or preferably overnight, until the custard is fully set.
25. Slice & Serve: For clean slices, use a sharp knife and wipe the blade clean with a damp cloth between each cut. This pie is best served the same day or within 24 hours for the best meringue texture.
