Step 1

Make the Crust: In a medium bowl, stir together the graham cracker crumbs, brown sugar, and salt, ensuring no lumps of brown sugar remain. Drizzle the melted butter over the graham cracker mixture and toss to combine with a fork, ensuring that the mixture is evenly moistened. Press the crust mixture evenly into the bottom and up the sides of a 9-inch pie plate, and pack tightly using the back of a measuring cup. Place in the freezer for at least 15 minutes.

Step 2

Assemble the Filling: Arrange the sliced bananas on the crust, then spread the dulce de leche over top of the bananas using an offset spatula or back of a spoon.

Step 3

Make the Coffee Whipped Cream: In a large bowl, whisk the espresso powder into the heavy cream until dissolved. Add the sugar and vanilla and, using an electric hand mixer or stand mixer with whisk attachment, whip on medium speed until frothy and beginning to thicken (2 to 3 minutes). Increase the speed to medium-high and beat for another 30 seconds to 1 minute, until still peaks form (the cream should look billowy and there should be distinct trails left by the whisk in the whipped cream).

Step 4

Spread the whipped cream over the filling and garnish with chopped hazelnuts (or peanuts) and shaved chocolate, if desired, and serve. Cover leftovers with plastic wrap and refrigerate for up to 3 days.
