A creamy keto key lime pie with cream cheese crust is simple to prepare! The low-carb filling is no-bake and sets up after a few hours in the refrigerator.
If you have been following my blog for a while, you know that I tend to favor the quick and easy low carb recipes. Like most working mothers, I don't have a lot of spare time for cooking and baking healthy food.
I believe that relying on fast or processed foods results in excess body weight and health issues. That's why I continue to make most of our food from scratch with only an occasional pre-made mix or heat and serve frozen meals.
My biggest weakness is still having a sweet treat after dinner. So I made a low carb key lime pie with cream cheese to share at a recent family gathering. It has a softer and lighter texture than a keto key lime cheesecake.
This recipe is made with simple ingredients. The pie filling blends heavy cream, sweetener, cream cheese, and key lime juice. For the crust, a blend of almond flour, cream cheese and sweetener is used.
I came across several traditional key lime pie recipes with cream cheese based fillings. But most called for sweetened condensed milk which is very high in sugar.
I decided to substitute the condensed milk with whipped cream to make it keto friendly yet still have the sweet creamy texture. To make up for the sweetness, I added a low-carb sweetener. The combo was a perfect substitute!
Rather than use a my almond flour pie crust, I added in some cream cheese for taste and texture. It's a fantastic base for this homemade keto key lime pie!
To make this simple keto dessert, you'll need to prepare the crust then add in the sugar-free key lime pie filling.
Cream Cheese Crust
I was very surprised at the results of combining cream cheese with almond flour and a little sweetener. The fat from the cream cheese turns the almond flour into a thick paste that was easily spread onto a pie pan.
However, the pie crust dough can be a little sticky if not chilled first. But using a pastry roller will make it easy to smooth out into the pan.
I baked the crust in the oven to make it more like a regular flour crust. It did puff up a little, so I recommend poking the dough with a fork before baking.
Keto Key Lime Pie Filling
The filling for this low-carb pie is no-bake. And, the taste was just what I was looking for!
You just need to combine cream cheese, powdered sweetener, and key lime juice with a hand mixer in a large bowl then fold it into whipped heavy cream. To up the key lime flavor, you can also add in a little key lime zest. The result is a light and airy key lime mousse that's really smooth and creamy.
For a true no-bake keto key lime pie, you could use a crust that requires no baking like a pecan crust or one make with low-carb graham crackers. You could probably just mix up some melted butter, almond flour, sweetener, and maybe a bit of cinnamon then press it into a pie plate.
