Step 1: Prepare the Crust

1. Preheat your oven to 350°F (175°C).
2. In a mixing bowl, combine the graham cracker crumbs, white sugar, and melted butter. Stir the mixture until it’s evenly coated, and the crumbs begin to clump together.
3. Press the mixture into the bottom of a square baking dish or your preferred dessert vessel. Use the back of a spoon or your fingers to firmly pack the crumbs down to ensure an even layer.
4. Bake the crust in the oven for 6 minutes, then remove it from the oven and let it cool while you work on the next layers.

Step 2: Make the Banana Pudding

1. In a large mixing bowl, whisk together the cold milk and the instant banana pudding mix. Whisk for about 2 minutes, until the mixture thickens slightly.
2. Add the softened cream cheese to the pudding and mix thoroughly using a hand mixer or stand mixer. This will help break up any lumps and create a smooth, creamy texture.
3. After mixing, place the pudding in the fridge to chill while you prepare the whipped cream and the Banana’s Foster sauce.

Step 3: Prepare the Whipped Cream

1. In a mixing bowl, add the heavy whipping cream, powdered sugar, and vanilla extract.
2. Using an electric mixer with a whisk attachment, whip the cream on high speed for 3-4 minutes, or until stiff peaks form.
3. Once the whipped cream has reached the right consistency, place it in the fridge to chill until you’re ready to assemble the dessert.

Step 4: Make the Banana’s Foster

1. In a large skillet, melt the butter over medium heat.
2. Stir in the dark brown sugar, banana liqueur, vanilla extract, and ground cinnamon. Let the mixture bubble gently for about a minute.
3. Add the sliced bananas and chopped walnuts to the skillet, stirring to coat them in the sweet sauce. Let the mixture cook for 4-5 minutes, until the bananas become soft and caramelized, and the sauce thickens slightly.
4. Remove the skillet from the heat and allow it to cool for a few minutes while you prepare for assembly.

Step 5: Assemble the Dessert

1. Begin layering the dessert in individual serving glasses (such as wine glasses or dessert cups).
2. Start with a layer of the graham cracker crust at the bottom of each glass.
3. Add a generous layer of the creamy banana pudding mixture on top of the crust.
4. Follow with a layer of whipped cream, spreading it evenly over the pudding.
5. Spoon the warm Banana’s Foster mixture over the whipped cream, making sure to include some of the caramelized bananas and walnuts in each serving.
