In a small mixing bowl, combine the graham cracker crumbs with the sugar, then add the melted butter and stir until the crumbs are well moistened.
Press the graham cracker crumbs into the tart pan and then freeze for 30 minutes.
Spread dulce de leche into the frozen crust.
Place banana slices in a single layer on top of the caramel.
Beat the cream and tablespoon of sugar till stiff peaks form.
Spread the whipped cream overtop of the tart and refrigerate for 3-4 hours.
Keep refrigerated until ready to serve, then slice and enjoy!
Notes
Press the crumb crust up the sides of the pan before covering the bottom of the pan to ensure a more even distribution. Chill time can be reduced to an hour or two if needed but tastes best if chilled at least 3-4 hours.
