When I don’t feel like baking a whole cake (even a small one), I often make a pie or tart. I had almost forgotten that I have a great key lime pie recipe.

I just rarely have it and make it. I was in Florida last month and couldn’t resist, but order a key lime pie in every restaurant that we went to. So I had key lime pie for dessert almost every day.

When I came back, I had to make my favorite recipe and share it with you.

This Key Lime Pie Recipe {Lightened Up}, used thick and creamy Greek yogurt, condensed milk, egg yolks, fresh key lime juice and key lime zest. The sweetness from the condensed milk makes is just perfect. And the flavor from the fresh key lime juice is amazing!

I’m a huge fan of citrusy desserts. Make sure you check out this Tangerine Layer Cake With Tangerine Curd And Cream Cheese Filling, Blood Orange Cheesecake Squares and Classic Lemon Bars With Shortbread Crust.

Key Lime Pie Recipe {Lightened Up}. Homemade Key Lime Pie, healthy, easy, impressive and tasty summer dessert. In a tin, topped with key limes and light whipped cream.

You actually don’t need to squeeze the key lime juice yourself, you can use store bought. But I’m the type of person, who loves cooking from scratch, when I have the time. Luckily, my local grocery store carries key limes almost year round, so I was able to use them in the recipe. If you can’t find key limes, you can use regular limes.

The perfect slice of key lime pie. Easy, healthy and delicious, effortless homemade summer dessert. Southern dessert.

By the way, what is the difference between key limes and limes? Key limes are much smaller, which makes extracting the juice  and zesting them a little harder. (I use this citrus juicer and my microplane zester for this). Key limes also have seeds inside (not fun!). These are the main differences between key limes and limes that I’m aware of.

For the crust, I used graham crackers and melted butter. I baked it for 10 minutes, before adding the filling. I rarely use sugar, when I make graham cracker crust. I just prefer my desserts less sweet, actually my whole family does. I’ve included sugar as an optional ingredient in this Key Lime Pie Recipe.

And here it is – the topping. Should you use a topping on a key lime pie? If you had asked me a few years ago, I’d say – YES! But I’ve chosen to skip the topping lately. As much as I like it, it is just extra calories. And there is no need of extra calories in a “lightened up” recipe.

Light, lower calorie key lime pie recipe. A slice of Key Lime Pie, on a metal plate, with lime zest on top.

If you decide to use topping, I’d suggest that you use fresh homemade whipped cream, instead of cool whip. Totally optional.

This lightened up key lime pie is super easy to make. Ready in under 1 hour. Tangy and refreshing, perfect for summer. Serve it at your next barbecue or a beach (pool) party.
