I don’t know about you, but the last thing I want on a baking hot summer’s day is a warm, heavy dessert. The best summer desserts are light, chilled and packed with the fresh flavours of berries or citrus – oh, and being able to be made quickly is an added bonus!
That’s where this delicious key lime pie comes in. Cool and creamy with just the right amount of bite, this pie is sure to become an instant favourite. With a perfectly balanced oat and brown sugar crust, and filled with a tangy, creamy lime filling, this is one summer dessert that’s sure to impress.
One of the things that makes this pie really special is the base. The trick? It’s made from a homemade oat biscuit recipe baked as a single giant cookie, then crumbled together to make the base. Pushed for time? Then simply skip this step and use store bought biscuits instead.
The added bonus? Despite being incredibly delicious, the filling is made of just four ingredients – cream cheese, condensed milk, egg yolks and lime juice; it couldn’t be much easier. Remember to add a little green food colouring to the mixture to get it that beautiful green colour you expect from key lime pie.
This pie would go perfectly along with a glass of your favourite infused water combination or a cheeky summer cider served in these gorgeous Chandelier glass jug and tumblers. The perfect summer treat!
