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 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

For The Crust:

  • graham cracker crumbs
  • butter

For The Key Lime Filling:

  • egg yolks
  • lime juice
  • sweetened condensed milk

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.

Steps

  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.
  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.
  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.
  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.
