Banoffee Pie: The Complete Guide to Britain's Favourite No-Bake Dessert
Banoffee pie is one of the rare British desserts with a documented invention story and an exact date: created in 1972 at The Hungry Monk restaurant in East Sussex, it has since become one of the country's most beloved desserts, built from just a handful of ingredients layered into something far greater than the sum of its parts.
The origin story
Banoffee pie was invented by Nigel Mackenzie and Ian Dowding, owners of The Hungry Monk restaurant in Jevington, East Sussex, who developed the recipe by adapting an American "toffee pie" from a Sixties cookbook, replacing the filling with a combination of banoffee — the name itself a portmanteau of "banana" and "toffee" — using boiled condensed milk to create the toffee layer. The dish quickly caught on beyond the restaurant and spread across British menus through the 1980s and 90s, eventually becoming a staple of home baking too, prized for how little actual cooking it requires.
The three essential layers
A proper banoffee pie has three clearly defined layers, and getting each one right matters more than any fancy variation: a buttery biscuit base, a thick toffee layer made from boiled or reduced condensed milk (dulce de leche, essentially), and fresh sliced banana under a generous layer of whipped cream, usually finished with a dusting of grated or shaved chocolate.
Ingredients (serves 8)
- 250g digestive biscuits, crushed
- 125g butter, melted
- 397g tin of condensed milk (or a ready-made tin of dulce de leche/caramel)
- 3-4 ripe bananas, sliced
- 300ml double cream
- 1 tbsp icing sugar (optional)
- Dark chocolate, grated or shaved, to finish
- A squeeze of lemon juice (to stop the bananas browning)
Method
1. Make the base
Mix the crushed biscuits with the melted butter until fully combined and the texture resembles wet sand. Press firmly into the base and slightly up the sides of a 23cm loose-bottomed tin or a pie dish, using the back of a spoon to compact it evenly. Chill for at least 30 minutes to firm up.
2. Make the toffee (safely)
The traditional method is boiling the unopened tin of condensed milk in a large pan of water for 2-3 hours, topping up the water regularly so the tin is always fully submerged — this is genuinely risky if the tin runs dry, as it can explode, so it needs constant attention. A much safer, faster alternative: empty the condensed milk into a pan and heat gently, stirring constantly, for 10-15 minutes until it thickens and turns golden-caramel, or simply use a ready-made tin of dulce de leche or caramel to skip this step entirely.
3. Layer the pie
Pour the toffee over the chilled biscuit base and spread evenly, then chill again until firm, at least an hour. Toss the sliced bananas in a little lemon juice to prevent browning, then arrange them over the set toffee layer.
4. Top with cream
Whip the double cream (with icing sugar, if using, for a touch of sweetness) to soft peaks — don't overwhip, or it will turn grainy once spread. Spoon or pipe the cream generously over the bananas, then finish with grated or shaved dark chocolate.

Ingredients
Method
- Mix the crushed biscuits with melted butter. Press into a 23cm tin. Chill for at least 30 minutes.
- Gently heat the condensed milk in a pan, stirring constantly, for 10-15 minutes until thick and golden, or use ready-made dulce de leche.
- Pour the toffee over the base and chill until firm, at least an hour. Toss the banana slices in lemon juice and arrange over the toffee.
- Whip the cream to soft peaks and spoon over the bananas. Finish with grated dark chocolate.
Troubleshooting: why is my toffee grainy or too runny?
Graininess usually means the condensed milk was heated too quickly or at too high a temperature, causing the sugars to crystallise — low, gentle heat with constant stirring is essential. A toffee that stays too runny generally just needs more time on the heat, or more chilling time afterward, since it continues to firm up considerably as it cools.
Variations
Add a layer of crumbled honeycomb or a drizzle of salted caramel for extra texture and flavour. Some versions include a thin layer of melted chocolate spread directly onto the biscuit base before the toffee goes on, adding a subtle bitter contrast to the sweetness above.
Make ahead, storing and freezing
The biscuit base and toffee layer can be made up to 2 days ahead and kept chilled and covered. Add the bananas and cream as close to serving as possible — bananas discolour and the cream can weep if left too long once assembled. Banoffee pie doesn't freeze well once fully assembled due to the fresh banana and cream, though the base and toffee layer alone freeze fine for up to a month.
Serving suggestions
Best served slightly chilled but not straight from the fridge — a short rest at room temperature brings out the flavours better. A cup of strong coffee alongside cuts nicely through the sweetness.

Frequently asked questions
Is boiling the tin of condensed milk actually safe?
It's a long-standing traditional method, but there is a genuine risk of the tin exploding if the water level drops and the tin overheats; the safer alternative of gently heating the condensed milk in an open pan achieves the same result with far less risk.
Why do my banana slices turn brown so quickly?
Bananas oxidise naturally once cut; tossing the slices in a small amount of lemon or lime juice before layering slows this down considerably.
Can I make banoffee pie in individual portions?
Yes — build the same layers in small glasses or jars for an easy dinner-party dessert; this also solves the slicing-and-serving challenge of a full pie.
Banoffee pie proves that a dessert doesn't need to be complicated to become a national favourite — just three well-executed layers, and a name good enough to remember.
