In the bowl of a food processor, combine all the ingredients except butter. Place the lid and process until mixed.
Remove the pusher and while the appliance is running, slowly pour in melted butter through the feeder tube.
Process until it resembles something similar to damp sand. To know if it’s the right consistency - take a measuring spoon, compress the mixture, drop it in your hand, and if it holds its shape, then it’s fine.
Drop the mixture into a 9-inch non-stick springform pie plate – if you don’t have a non-stick one, lightly grease it with butter.
Using the bottom of a small measuring cup or glass, press crumbs firmly up the sides as high as possible and evenly on the bottom.
Transfer the pie plate to the preheated oven and bake for 5 minutes.
Remove from the heat and place it on a wire rack. Set aside to cool completely while making the whipped cream.
FILLING
When the pie crust is at room temperature, pour in dulce de leche, and using a spatula, spread it out evenly.
Place banana slices on top before sprinkling on pieces of toffee bits.
TOPPINGS
Evenly spread whipped cream on top of the pie and garnish with toffee bits.
Refrigerate pie for 2 hours before serving.
Cover leftovers and store in the fridge for up to 2 days.
