Start by making the graham cracker crust. Lightly crumble the graham crackers as you add them to a food processor. Then, add the brown sugar, and cinnamon. Thoroughly pulse these ingredients in the food processor. After that, add the applesauce and pulse again until the crust is combined.
Transfer the graham cracker crust from the food processor to your pie dish. Form the crust in your pie dish and press it together using your hands and the bottom of a measuring cup. Thoroughly press it together in the pie dish to form the crust.
Bake the graham cracker crust at 350°F for 10-12 minutes. Once baked, let the crust cool. Allow about 15-20 minutes for it to cool.
While the crust cools, make the pudding. Add the cold milk to a large bowl along with the vanilla instant pudding mix. Use an electric hand mixer to combine these ingredients to form the pudding, this will take about 3 minutes.
As an option, mix the vanilla extract into the whipped cream.
Peel and slice the bananas just before assembling the pie so they don’t get brown.
Once the crust has cooled and you are ready to assemble the pie, start with a layer of banana slices. Then, add a layer of pudding. After that, add a final layer of banana slices and pudding. Thoroughly cover the bananas with the pudding when layering, however, you may have some pudding left over. You don’t have to add all of the pudding to the pie. You can use leftover pudding to make an individual serving.
Chill the pie in the refrigerator for at least 2 to 3 hours, to allow the pudding to set.
Once chilled, top the pie with whipped cream. Then, cut it into eight slices, serve, and enjoy!
