One of my intentions for this new year was to create, revisit and post some classic recipes here on the blog. As a self-taught baker, after mastering the basics, I spend a lot of time trying to come up with new recipes with unique flavor combinations and realized I tend to leave out the classics that we all love so much. To fix that, I’ve been posting some of my favorite classic recipes for you guys that I use daily in my kitchen. So far, I’ve shared with you my classic vanilla cupcake recipe, classic chocolate cake recipe and today, this classic key lime pie recipe!

I’ve always been a citrus fan but surprisingly key lime pie was never on my favorite list until last year when I had a killer slice at a local restaurant that changed everything and since then I’ve been chasing all things key limes everywhere. Even on a recent trip to Whole Foods in DC where I tried their mini key lime pie tarts and just had to make myself a pie when I got home. (Totally off topic: I don’t live in a city with a Whole Foods Market, which is extremely sad. So whenever I travel to another city, it’s a destination to ravel in! Consider yourself blessed my friends if you have a whole foods in your city/town).

When researching recipes for homemade key lime pie recipe, I realized all the classic recipes use sweetened condensed milk. This is not a usual ingredient in my kitchen (no reason at all) so I was skeptical at first but I knew it must be the secret to a killer key lime pie, so I went with it. Most of the recipes are similar; graham cracker crust, condensed milk, egg yolks and key lime juice. Seems easy if you ask me. So I adapted a few… more for the ratios and I added a bit of coconut cream as well to mine because you know coconut and lime = freaking amazing.

For a more classic key lime pie recipe, you can leave the coconut cream out, as I did in the recipe below.

The resulting pie is a creamy, sweet, tart pie with a rich key lime flavor.

Yield: 1 9-inch pie
  • 1 ¼ cup graham cracker crumbs (1 sleeve graham crackers)
  • 2 tablespoons granulated sugar
  • 5 tablespoon butter, melted
  • 1 14-oz can sweetened condensed milk
  • 4 large egg yolks
  • ½ cup key lime juice (freshly squeezed or bottled)

  3. Bake crust for 8-10 minutes, or until golden. Remove crust from oven and let cool completely.
To make the filling:
  1. In a medium bowl, whisk together the condensed milk and egg yolks until smooth and slightly thickened. Add in key lime juice and zest. Whisk mixture for about a minute, until well combined and thickened.
  2. Pour the filling into the prepared cooled crust and bake for 15 minutes in 350 degrees F. Transfer pie to a cooling rack and let cool completely at room temperature before chilling for at least 3 hours or overnight until set.
  3. When ready to serve, beat the cold heavy cream until soft peaks form. Top pie with whipped cream.
For a coconut key lime pie, add ⅓ cup coconut cream to the filling. Top pie with toasted coconut flakes when ready to serve. It's really good!!
