Ah, the key lime pie – an American classic dessert – but sadly it isn't usually low carb. So when I was looking through Stacey Crawford's fantastic new book: Keto in an Instant – and saw a crustless version, I knew that I just *had* to make it!
It isn't just desserts in the book, by the way, there is SO much more! Highlights for me include Chile Queso Dip, Steamed Artichokes with Creamy Dijon Sauce, Bacon Cheeseburger Salad, Hawaiian Pulled Pork, and Slow Cooker Pizza Casserole! You can buy the book on Amazon (of course!) – and it's perfect for some wonderful low carb recipe inspiration!
Oh – and the other reason that I really wanted to try this recipe was that ages ago I bought a 7″ springform pan to fit into my Instant Pot – and never used it! Finally – I had a recipe for it! I started by lining it with parchment paper.

How to Make a Keto Crustless Key Lime Pie
In a stand mixer, I combined softened cream cheese, low carb granular sweetener (I used Swerve), coconut flour and vanilla extract until smooth. Then I slowly added two eggs and an egg yolk. Finally, I added some key lime juice (from a bottle, because fresh key limes aren't in season yet – and I just couldn't wait!), and blended again.
I poured everything into the prepared pan, covered it with a paper towel, and wrapped it in foil.
I placed a steam rack inside my Instant Pot together with some water, then put the springform pan onto the rack. I locked the lid down, and sealed it. I cooked it on Pressure Cook (high) for 44 minutes (very precise – but it seemed to work!). When the cooking time as complete, I let the pressure release naturally.
I carefully removed the pan, and removed the paper towel. When the pan was cool, I recovered it in foil and let it set in the fridge overnight.
The next day, I carefully removed the sides of the springform pan and the paper at the sides. For the topping, I beat some heavy cream and sweetener until stiff, then smoothed it over the pie (I didn't need quite as much as Stacey recommended in the book, but then again she does recommend slicing the pie THEN adding the topping!
To finish, I added some finely grated lime zest using my Microplane.
It looked really pretty, even if I do say so myself!
It tasted great, too – a perfect balance of creaminess, sweetness, and citrus!
