If you love the tangy flavor of a classic Key Lime Pie, you’ve got to try this single serving version. It’s everything you want in a pie: refreshing, creamy, and packed with citrus flavor in a portion that’s just right for one person.
I make this recipe when I want something sweet that doesn’t take much time or effort. The buttery graham cracker crust pairs perfectly with the smooth lime filling, and a dollop of whipped cream on top makes it feel extra special.

- Graham Cracker Crumbs: These make up the crust base. Use graham crackers or substitute with gingersnaps, vanilla wafers, digestive biscuits (UK), or Arnott’s Granita biscuits (Australia). Leftovers? Use them in no-bake single serving cheesecake, baked s’mores dip, or single serve peanut butter pie.
- Egg Yolks: Provide the creamy texture in the filling. Save the egg whites for egg white recipes like single serving coconut macaroons or our small pavlova recipe.
- Lime Juice: Fresh lime or bottled both work. For classic flavor, use key lime juice if available.
- Sweetened Condensed Milk: Sweetens and thickens the filling. Freeze leftovers for up to 3 months or use in single serving chocolate ice cream, small tres leches cake, small batch mint chocolate chip ice cream, or our small batch microwave fudge recipe.

This recipe was just what I was looking for! A single key lime pie treat for myself. Very easy to make, delicious and satisfying. I actually had some key limes but did not want to make a whole pie. Thank you!
I’m so glad you enjoyed the pie, Judy. Thank you so much for your feedback.
Great recipe
Will using key limes and regular limes make a big difference? I also cant wait to make this, they look delicious, already bought the ingredients and more to make multiple times!
No, just use the same amount of lime juice as called for in the recipe. Enjoy!

I absolutely love key lime pie, this is so delicious!
This looks amazing! I’m not the biggest fan of Key Lime pie but my boyfriend LOVES it. I’ll have to surprise him with this and it’s perfect since it’s for one!
I love finding a good “for one” recipe, saves me from eating an entire pie to myself! Loved this one!!
OMG this is great!
