- 1 9-ounce package chocolate wafers (such as Nabisco Famous Chocolate Wafers)
- 1/3 cup unsalted butter, melted
- 3 egg yolks
- ½ cup granulated sugar
- ¼ cup cornstarch
- ¼ teaspoon salt
- 2 ½ cups whole milk
- 4 ounces white chocolate chips
- 1 ¼ teaspoon vanilla, divided
- 3–4 medium bananas
- 1 cup heavy cream
- 2 tablespoons sifted powdered sugar
- For optional garnish: Dark chocolate and white chocolate curls (see note below recipe for some tips on creating the chocolate curls) and extra slices of banana
- In the bowl of a food processor, process the chocolate wafer cookies until they are fine crumbs. In a small bowl, place 1½ cups of the chocolate crumbs and hold the remaining crumbs aside in a separate bowl.
- In a medium bowl, combine the 1½ cups of chocolate crumbs with the melted butter and stir to mix well. Press crumbs evenly into the bottom and up the sides of a 9-inch pie plate to form a solid crust. Place in the refrigerator to chill while you begin making the custard for the pie.
- In a medium bowl, lightly beat the egg yolks. Set aside.
- In a heavy bottomed saucepan, combine sugar, cornstarch, salt and milk. Stirring constantly heat over medium heat until the mixture just starts to get bubbly and thick. Cook for 2 minutes, stirring constantly.
- Remove the pan from the heat. While whisking, gradually add a few spoons of the hot custard mixture to the bowl with the egg yolks, being sure to whisk quickly so the yolks do not start to cook or curdle. Keep whisking and slowly add more of the hot custard mixture to the yolks, until you have about a cup of custard in the bowl with the yolks.
- Add the egg yolk mixture back into the pan and stir. Heat the mixture in the pan back up over medium heat, again stirring constantly. Once it starts to bubble, reduce heat to low and cook for 2 more minutes. Remove from heat and stir in white chocolate chips and 1 teaspoon of the vanilla, stirring until the chocolate melts completely. Allow the white chocolate custard to cool slightly.
- Slice two of the bananas and place in a single layer over the chilled crust. Spoon half of the custard filling over the bananas and spread into an even layer. Sprinkle the remaining chocolate crumbs over the custard. Then slice the remaining bananas and place over the chocolate crumbs, then spoon the remaining custard over the bananas. Cover and chill for at least 4 hours so the custard cools and the pie sets.
- When ready to serve, in the bowl of a stand mixer and with the wire whip attachment, combine heavy cream, remaining ¼ teaspoon vanilla and powdered sugar. Whip at high speed until stiff peaks form. Spread whipped cream over the pie. Garnish with shaved chocolate and additional banana slices.

To make the chocolate curls, just use a vegetable peeler and shave off thin slices of chocolate from a premium white and dark chocolate bar. The best curls will come from using chocolate with a high fat content (we used Ghirardelli’s).
