I often find myself craving the taste of a creamy and rich key lime pie or other dessert that I remember making for my kids. Now that I cook for a smaller household, I really don’t want to have leftover desserts in the house for days.

Single serving recipes are perfect for me now and I’m excited to share with you the best key lime pie recipe for one!

This key lime pie recipe is ideal for those very moments. It’s easy to make and I think this recipe makes the absolute best key lime pie in a single serving portion!

One of the reasons I love this pie in addition to its size is the fact that the tartness of the pie filling is perfectly balanced by its sweetness.

What Is Key Lime Pie?

Key lime pie is an American dessert made with key lime juice. It is typically made with a graham cracker crust and is a specialty of the Florida Keys.

What Is The Difference Between Key Limes and Regular Limes?

Key limes are more aromatic and tart than regular limes. They are slightly yellow and contain more seeds.

Can I Use Regular Lime Juice In This Key Lime Pie Recipe?

Yes, you can use the juice from regular limes in this key lime pie recipe.

How To Make Key Lime Pie

Like a traditional key lime pie, this mini pie has a graham cracker crust.

Scroll down to the recipe box for the ingredient amounts and complete recipe instructions.

Ingredients In A Key Lime Pie For One:

For The Crust:

  • graham cracker crumbs
  • butter

For The Key Lime Filling:

  • egg yolks
  • lime juice
  • sweetened condensed milk

Step 1

Mix together 1/4 cup of graham cracker crumbs (approximately 2 large sheets of graham crackers) and melted butter.

Pour the crumbs into an 8-ounce ramekin and bake for about 15 minutes to set the crust.

Step 2

After the crust has baked, pour in the key lime custard which is a mixture of sweetened condensed milk, two egg yolks and lime juice.

Pro Tip: Key lime juice is wonderful if you can find key limes and if you can, by all means use them. When I can’t find key limes, regular limes will do just fine or use bottled key lime juice.

Step 3

Bake the pie in the oven for about 15 minutes.

Remove from the oven to cool a bit and chill in the refrigerator for at least 1 hour.

Step 4

Top with whipped cream and enjoy!

For this Key Lime Pie For One recipe, I use a ramekin that holds about 1-cup. For best results, please use a baking dish of similar size.

    I absolutely love key lime pie, but my fiance isn’t a fan, so a small portion just for 1 is perfect! I’ll have to try it soon!

  3. 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!

  4. OMG this is great! My hubby loves Key Lime Pie but I don’t eat it, and being able to make just one mini pie for him would be fantastic! Thanks so much for sharing, can’t wait to try this!

  5. Sometimes I really want a dessert, but I don’t want to make a ton of it because it’ll go to waste. I love that you made a recipe that is just for one person, I feel like it’s perfect for me. It looks delicious!

  6. One of my favorite deserts is key lime pie. The fact that I can whip this up just for myself when the craving hits is amazing! I have pinned the recipe and cannot wait to try it 🙂

  7. This is perfect! Sometimes you want a little treat, but don’t feel like making an entire dessert (because you’ll end up eating the whole thing!). I can’t wait to try this for Summer!

    Key lime pie has been one of my favorites since I was a kid. Thank your son Stephen for me for inspiring you to make this single-serving recipe!

  11. I love that this is a single portion. It is my favorite way to make dessert and does not stress my willpower to the limit.

  12. Kirsten/ComfortablyDomestic

    Key Lime Pie is my husbands absolute favorite dessert! This recipe could be a dangerous thing for him.

  13. Erin @ Texanerin Baking

    That’s so neat that you’re teaching your kids to make individual serving desserts. 🙂 And this one looks amazing! I’ve been working on a key lime bar recipe and I’m so sick of having aaall those bars around. I much prefer this!
