To make dulce de leche, place Sweetened Condensed Milk (14 ounce) in a saucepan and cover with water.
Boil on medium heat for 2 1/2 to 3 hours. Remove the can and wait until is cool slightly before opening it.
In a medium size bowl, mix together the Graham Cracker Crumbs (2 cup) and Butter (8 tablespoon). Mix until it looks like wet sand.
Spread on the bottom and sides of a tart pan or pie plate and chill in the fridge.
In a medium bowl, add Heavy Cream (1 1/4 cup) and Granulated Sugar (1/4 cup) and whip it up. Refrigerate until needed.
Spread the Dulce de leche (toffee) over the crust. Slice up a couple of Banana (2) on top of toffee. Spread over the whipped cream. Cover with plastic wrap or aluminum foil. Place it in the fridge for 2-3 hours.
Garnish with Chocolate (to taste), serve and enjoy!
