Method
Make the Biscuit Base
- Lightly grease a 9-inch (23cm) tart pan with a removable bottom or a 9-inch springform pan. A removable-bottom pan makes the finished pie considerably easier to serve.
- Crush the digestive biscuits in a food processor and pulse until they resemble fine crumbs. Alternatively, place them in a sturdy zip-top bag and crush them with a rolling pin. If you're using prepared graham cracker crumbs, simply measure them into a bowl.
- Mix the crumbs with the melted butter until evenly moistened. Press firmly across the bottom and approximately 1 inch (2.5cm) up the sides of the pan. The bottom of a measuring cup works well for pressing the crust evenly without compacting it excessively.
- Refrigerate the crust for at least 30 minutes while you prepare the toffee.
Make the Toffee Filling
- Place the butter and brown sugar in a medium heavy-bottomed saucepan over medium-low heat. Cook gently, stirring, until the butter has melted and the sugar has mostly dissolved.
- Add the sweetened condensed milk and bring the mixture to a gentle boil, stirring continuously. Once bubbling, cook for approximately 2–3 minutes, continuing to stir constantly. The mixture should become slightly darker and noticeably thicker. Remove from the heat and stir in the vanilla and salt.
- Allow the toffee to cool for approximately 5 minutes and pour it into the chilled biscuit crust and spread it into an even layer. Refrigerate for at least 3 hours, or until the toffee is completely chilled and firm.
Add the Bananas and Cream
- Shortly before serving, peel the bananas and slice them into rounds approximately 1/4 inch (6mm) thick. Arrange the banana slices over the chilled toffee.
- Pour the cold heavy whipping cream into a large bowl. Add the powdered sugar and vanilla. Whip until soft to medium peaks form.
- Spoon the whipped cream over the bananas. Spread it gently with the back of a spoon, leaving natural swirls and peaks rather than creating a perfectly smooth surface.
Finish and Serve
- Finish with finely grated chocolate, chocolate curls or a light dusting of cocoa powder. Keep refrigerated until ready to serve.
Notes
Press the biscuit crust firmly enough to hold together, but don't compact it excessively. A good banoffee crust should remain slightly crumbly when sliced.
Brit & Skillet Tip: Add the bananas relatively close to serving time. The biscuit base and toffee can be prepared well ahead, but freshly sliced bananas have the best appearance and texture.
