In a mixing bowl, combine the crushed graham crackers, granulated sugar, and melted butter. Stir until the mixture resembles wet sand. Press it firmly into the bottom of a 9-inch pie pan to form a crust.
In another bowl, whisk together the whole milk, instant vanilla pudding mix, and vanilla extract for about 2 minutes until it’s smooth and thickened.
Arrange the sliced bananas evenly over the prepared graham cracker crust. Pour the pudding mixture over the bananas, spreading it out to ensure even coverage.
In a separate bowl, whip the heavy cream and powdered sugar until soft peaks form. Spread this luscious cream over the pudding layer evenly.
Cover the pie with plastic wrap and refrigerate for at least 2 hours to set. When you’re ready to serve, garnish with additional banana slices and crushed graham crackers.
Notes
For a gluten-free option, use gluten-free graham crackers. To lighten it up, substitute whole milk with almond or oat milk.
