Bananas and peanut butter go together perfectly and this dessert is no exception. A delicate butter crust is the base for this rich and delicious dessert. The crust is then topped with layers of pastry cream and sliced bananas before a creamy peanut butter whipped cream is spread across the whole thing. A sprinkling of peanuts adds a bit of crunch that balances out the dessert. If you want something even more decadent, drizzle melted dark chocolate over the whole pie.
