About this time of year, I start to wonder if I’d rather hang on to summer a bit longer or see fall make it’s arrival. I feel like we’ve had a relatively mild summer, but it’s definitely pretty warm this time of year and I’m never sad to see fall temperatures. However, it’s been one crazy busy summer and I don’t feel like we’ve gotten to fully enjoy it. I’m still hoping that in the next few weeks, we’ll get a chance to get out on the lake and enjoy a day with the sun on our skin.

Not to mention that I’m not entirely sure I’m ready to say goodbye to some of my favorite summer flavors. I love all the fresh fruit of summer and I’m already sad to see less of it available and not so much on sale. And then there’s the tropical flavors of summer like pina colada and key lime. Is it even possible to get tired of those? I think not.

So today I’m holding onto summer just a bit longer with this No Bake Key Lime Cheesecake. And if you live in an area where heat + turning on your oven = no good. This cheesecake is even better for you. It’s easy to make, cool and refreshing. Bring it on!

This cheesecake gets started with a classic graham cracker crust. I like to add a touch of sugar to my crusts, which I did in this one. It just takes it up a notch and I’ve never been one to shy away from a touch more sugar. 🙂 I did happen to bake this crust, but you absolutely can pass on that step if you prefer and want it truly, hard-core no bake. I just like to bake it quickly because the crust holds together better when you cut into it. Your call though.

And then there’s the filling. It includes the best parts of a key lime pie in cheesecake form – heavenly sweetened condensed milk and of course all the key lime flavor of key lime juice and zest. Key limes themselves can be hard to find, so feel no shame in buying the bottled juice. It’s what I do and it’s always delicious. If that’s what you decide to do as well, you can use regular limes for the zest and decor. It’ll be fine and still taste like key lime, I promise. 🙂

Top the cheesecake off with some swirls of whipped cream and slices of key lime (or limes) and you’ve got an easy, super tasty and fun treat! We all loved how smooth, creamy and delicious it was!
