Banoffi Pie

Cook the condensed milk in a nonstick pan over a medium heat until it starts to look a little thicker and caramel-y. Don't cook it too long or it will be chewy when it's cold. Butter 8-inch flan tin (pie pan or tart pan -- whatever you've got) and line with a thin layer of pastry. Bake blind until crisp (I give it the ol' stab-with-a-fork routine before baking). Whip the cream with the coffee and sugar until thick and smooth. Empty toffee mixture onto the baked crust and spread. Layer the chopped (or sliced) bananas and top with the whipped cream.
