Key Lime Pie

Now that Spring is here it’s time to start thinking about summer desserts – well, at least it is around here! I don’t know about you, but the last thing I want on a stinking hot summer’s day is a warm, stodgy  dessert.

Obviously, we’re not quite at that stage yet – we’re only four days into Spring – but there’s no harm in getting a bank of fail proof summer recipes prepared ahead of time! So that’s exactly what I’ve been doing – coming up with a list of delicious summer recipes that can be made super quickly!

And I’m in love with the first one – a delicious key lime pie!

Cool and creamy with just the right amount of bite, this pie has become an instant favourite in our house. This key lime pie is a perfect balance of oat and brown sugar crust, and tangy, creamy lime filling – perfection!

One of the things that makes this pie really special is the base – something you don’t hear often, I know! The trick with it is it’s made from a homemade oat biscuit recipe baked as a single giant cookie, then crumbled and combined into the final base mixture. While you could certainly use store bought biscuits instead, there’s something incredibly satisfying about knowing the entire thing has been made from scratch. Bonus? It tastes delicious too!

After preparing the filling and pouring it into the base, simply pop the pie in the oven for ten minutes. That’s right – it only takes ten minutes to bake! Then it’s just a matter of cooling it down; first to room temperature on the bench, then nice and cool in the fridge.

Before serving I finished my pie with a wee puff of whipped cream – the perfect complement to the tangy pie filling. From the very first bite this pie got the seal of approval from everyone who tasted it – this is one recipe that will definitely be getting a thrashing this summer!
