Flapper pie is a classic Canadian dessert that features a creamy custard filling topped with a fluffy meringue, all nestled in a buttery graham cracker crust. This nostalgic treat is perfect for any occasion and is sure to impress your guests with its delightful combination of textures and flavors.
Most of the ingredients for this flapper pie recipe are common pantry staples, but you may need to pick up a few items at the supermarket. Make sure you have graham cracker crumbs, cornstarch, and cream of tartar on hand, as these might not be in your usual stock. The rest of the ingredients, such as milk, sugar, eggs, and vanilla extract, are more commonly found in most kitchens.

Ingredients for Flapper Pie Recipe
Graham cracker crumbs: Crushed graham crackers used to form the pie crust.
Sugar: Sweetens the crust, custard, and meringue layers.
Melted butter: Binds the graham cracker crumbs together to form the crust.
Milk: Forms the base of the custard filling.
Cornstarch: Thickens the custard filling.
Egg yolks: Adds richness and color to the custard filling.
Vanilla extract: Adds flavor to the custard filling.
Egg whites: Whipped to create the meringue topping.
Cream of tartar: Stabilizes the egg whites for the meringue.
Sugar: Sweetens and stabilizes the meringue.
Technique Tip for This Recipe
When making the meringue, ensure that the egg whites are at room temperature before beating. This helps them whip up more easily and achieve greater volume. Additionally, make sure your mixing bowl and beaters are completely clean and free of any grease, as even a small amount of fat can prevent the egg whites from reaching stiff peaks.

How to Store or Freeze This Pie
- To store your delightful flapper pie, allow it to cool completely at room temperature. This ensures the custard sets properly and the meringue maintains its texture.
- Once cooled, cover the pie with plastic wrap or aluminum foil. Ensure the wrap is snug but not too tight to avoid marring the meringue.
- Place the covered pie in the refrigerator. It can be stored for up to 3 days, maintaining its deliciousness and texture.
- For longer storage, consider freezing the pie. First, place the pie in the freezer uncovered for about 1-2 hours. This initial freeze helps the meringue and custard firm up.
- After the initial freeze, wrap the pie tightly with plastic wrap, followed by a layer of aluminum foil. This double wrapping prevents freezer burn and preserves the pie's flavor.
- Label the wrapped pie with the date of freezing. The flapper pie can be frozen for up to 1 month.
- When ready to enjoy, thaw the pie in the refrigerator overnight. Avoid thawing at room temperature as it can cause the custard to become watery and the meringue to weep.
- For a freshly baked taste, you can reheat the thawed pie in a preheated oven at 350°F (175°C) for about 10 minutes. This step helps to refresh the meringue and bring back some of its original texture.
How to Reheat Leftovers
Preheat your oven to 325°F (165°C). Place the flapper pie on a baking sheet to catch any drips. Cover the pie loosely with aluminum foil to prevent the meringue from browning too much. Heat for about 10-15 minutes or until warmed through.
For a quicker method, use a microwave. Place a slice of flapper pie on a microwave-safe plate. Heat on medium power for 20-30 seconds. Check the temperature and continue heating in 10-second intervals until warm. Be cautious as the custard can overheat quickly.
If you prefer a stovetop method, use a double boiler. Place the flapper pie in a heatproof dish and set it over simmering water. Cover the dish and heat for about 10 minutes, checking frequently to ensure even warming.
For an air fryer, preheat to 300°F (150°C). Place the flapper pie in the basket, ensuring it is stable. Heat for 5-7 minutes, checking halfway through to ensure the meringue doesn't overcook.
