Instant Pot Key Lime Pie is a small slice of heaven. This perfectly tart, smooth, sweet recipe tastes exactly like its classic big brother, but in a perfect single portion.

Key lime pie for one

Key lime pie is an ideal treat for a late summer afternoon relaxing in the sun. But what about when you live alone, or just need enough dessert to satisfy your craving without ruining your health and fitness goals? 

I’m sure you know the struggle: you want to bake, but no one else will eat your creations. What then? Eat an entire pie yourself? Let the rest go to waste? Both options aren’t the best!

I completely understand and I have a solution! The individual key lime pie.

This single portion key lime pie recipe from my new cookbook is designed to make just one serving, but you can adjust for however many servings you want!

The result is a cute, perfectly portioned mini key lime pie with a delicious graham cracker crust.

Easy key lime pie

Not only is this pressure cooker key lime pie perfect for one serving; it’s really easy! Because this key lime pie recipe uses condensed milk, it has loads of rich sweetness without tons of effort on your part.

This pie bakes in a small ceramic ramekin (I use these!), rather than a traditional pie pan. So you don’t have to worry about buying a mini pie pan. 

Instant Pot key lime pie bites

Key Lime Pie Bites are a fun twist on this recipe! These little bites transform a traditional dessert into a creative, refreshing appetizer. They’re super easy to bring to gatherings—a guaranteed crowd pleaser.

To make Instant Pot key lime pie bites is simple!

  • Make the crust and divide it evenly in a silicone egg bite mold (about 1-2 teaspoons per bite)
  • Make the filling as detailed in the recipe and fill the mold with however large you want each bite.
  • Follow the recipe to cook the bites the same way you’d cook the pie in a ramekin.

You can expect to make 5- 7 bites.

How to make Instant Pot key lime pie

Let’s get to it: how do you make mini key lime pies in an Instant Pot? 

You’ll note that the ingredients are divided into crust and filling. Mix up the crust ingredients first and press into a ceramic ramekin, then mix up the filling and pour it over the crust. 

To cook, cover and steam your mini pie in the Instant Pot for 10 minutes with a natural pressure release, then let it cool to room temperature.

It does require 4-6 hours in the fridge before serving, so be sure to make it ahead of time. I find that it’s a great treat to make on Sunday morning—it’s chilled and ready by dinner time!

  1. I lost my limes at the last minute, BUT I did have lemons (for zest) and lemon juice on hand. So I substituted the lime zest and juice with lemon to make a mini lemon pie. It was SO GOOD! Still can’t wait to try it with limes though because I do love key lime pie. I also recommend homemade whipped cream. YUM. It was the perfect size treat.

    I’ve made this several different times, it’s amazing! My only comment is that one can reduce the amount of Graham cracker crumbs.

  3. In your new cookbook, amount of sweetened condensed milk calls for 1/2 cup. On website recipe calls for 1/3 cup. Which is it?

      Hi Helen! The amount for the pie is 3.5 oz, but my publisher rounded up to 1/2 cup (.4375 cup). I find it’s better with just a touch less, so I go with 1/3 cup on my website (2.7 oz). Any amount between 1/3 and 1/2 will work. Hope that helps.

  4. Target in Alaska does not have your book, cooking for one. I have not used Amazon since I purchased two large air fryer ovens for Christmas gifts that did not work as advertised, and some crooks in Florida used my credit card number to purchase “boner” pills. The only card I have is a cash card from Walmart. I had to cancel the card, and just lost the money. Amazon would not refund the loss to my cash card for the theft for “boner” pills, but after four months of one test after another on the large air fryer ovens, they finally did refund the purchase of the large air fryer ovens. So last years ruined Christmas, and the cancelled cash card Amazon is not where I would try to get your cooking for one cook book. But as you can probably guess, from the two large air fryer orders for Christmas presents, I wanted to get two copies of your cooking for one cook book. But I won’t risk ordering from Amazon, and Target does not have your book in Alaska. But thank you very much for writing it anyway. I ordered my pressure cooker because of you, and another for my friend. We both live alone at separate places about five miles apart. We have a number of friends who live alone like we do, and your cooking for one would be great gifts for all our friends. If you can find where to go in and buy them in Alaska please let me know. Maybe I can get a number of them and give them as gifts. Thank you for your help. Don Hart [email protected]

    Hi Lisa, I’ve had my instant pot for a couple years, and yours was the first site that I learned from. I normally cook for just one, and I also have your book! I love the soup recipes especially.

    I love to make the key lime pie, but I bought a set of 8 oz ramekins on Amazon and your recipe almost fills two of that size. I’m not complaining because it helped me learn the proper amount if I’m cooking for multiple people, but I was wondering if you could link the 8 oz ramekin that you bought. Or is it possibly bigger in the picture? I want to try your molten lava cake and it calls for the same size…. I definitely want it all in one serving so I don’t have to share!
