Like everyone else I have been binge watching TV series during lockdown and had got back into Dexter, and an episode put Key Lime Pie back in my head.
The pie is usually made with a digestive biscuit (graham cracker) crumb base, but I’ve made mine with an Oreo crumb base mainly because I just like the contrast in colour (please don’t be tempted to add green food colouring the lime layer) . I’ve also added a whipped cream topping which you can leave out if you don’t like creamy desserts. A traditional pie apparently never had cream because it was difficult get and keep cream fresh in the Florida Keys where the pie originally came from. I also used supermarket own of Oreos which worked out to be much cheaper. Some places sell ready made Oreo pie cases, so if you’re short on time you could also use one of these.
Feel free to revert to the original pie, but I’ve only ever had thumbs up for this version. It’s really good as a dessert that you can make a head and take out of the fridge when you are ready to serve, or treat yourself and enjoy a slice with your afternoon coffee.
For the Crust
400 Grams Oreos
70 Grams Butter (melted)
For the Filling
1 x 397 Can of Condensed milk
3 x Egg yolks
4 x Limes (juice and zest)
300 ml Fresh Cream (whipped)
1 Tbsp Icing sugar
Extra Lime zest to decorate
- Add the Oreos to a food processor and whizz until you have fine crumbs. I had to do this in 2 batches but it will depend on the size of your processor. Transfer the crumbs to large bowl and stir in the melted butter. Pre heat your oven 180 degrees (Celsius)
- Line the base of a 21-22 cm spring form cake tin with baking parchment and grease the sides of the tin with butter.
- Pour the Oreo mix into the tin and with a glass or the back of a spoon press the crumbs up the sides of the tin, until there is a crust of around 4-5cm. Make sure the base is well covered too. Bake for 15 minutes and allow to cool
- Add 3 egg yolks to a bowl or mixer and whisk until the yolks lighten in colour and increase in volume
- Add the condensed milk, and lime juice and zest and whisk for 2-3 minutes
- Pour the filling into the cooled pie base and bake at 160 degrees (Celsius) for 15 minutes before removing from the oven and allowing to cool
- When the pie is completely cool, whisk the cream and icing sugar together until it forms soft peaks. Spread over the top of the baked pie and add some finely grated lime zest for a finishing touch
