What Makes This Dish Special

There's a good reason everyone loves this Key Lime Pie. The silky filling strikes the perfect balance between tart lime and creamy condensed milk, while the graham base gives you that satisfying crunch in every bite. Don't worry if you're new to baking—this is so simple anyone can nail it. You can also switch things up with different crusts or add your own special touches on top.

What You'll Need

  • Graham Crackers: 1½ cups smashed into fine crumbs for your base.
  • Butter: 6 tablespoons melted to hold your crust together.
  • Sugar: ¼ cup for crust mixture, another 2 tablespoons saved for the cream topping.
  • Condensed Milk: 2 cans (14 oz each) sweetened for that luscious texture.
  • Key Lime Juice: ¾ cup squeezed fresh or from a bottle for that real deal flavor.
  • Egg Yolks: 4 large ones to make everything stick together nicely.
  • Heavy Cream: 1 cup to whip into a fluffy cloud for the top.
  • Lime Zest: From 2 limes to sprinkle and add extra zing.

Crafting Your Base

Set Up Your Baking Area
Turn your oven on to 350°F (175°C). Rub some butter or spray around a 9-inch pie dish.
Mix Your Crust Stuff
Grab a bowl and stir together your graham crumbs, melted butter, and sugar until it looks like damp sand.
Shape It Just Right
Push this mix firmly into your dish, covering the bottom and working it up the sides. A measuring cup works great to pack it down evenly.
Quick Bake
Pop it in the oven for about 7-8 minutes till it's slightly golden. Pull it out and let it cool while you work on the next part.

Whipping Up The Lime Mixture

Blend Your Filling
Grab a big bowl and mix the sweetened condensed milk, Key lime juice, and egg yolks until everything's nice and smooth.
Kick Up The Taste
Throw in a tablespoon of lime zest to give it more punch and add tiny green flecks throughout.
Into The Oven
Pour everything into your cooled crust and bake for 15-18 minutes, until you see tiny bubbles popping on top and it's just barely set.
Check If It's Done
Give the pie a gentle shake—it should wobble a bit in the middle. Don't cook it too long or it'll get tough. It'll firm up more as it cools.

Finishing Touches

Let your pie cool all the way down before you wrap it with plastic and stick it in the fridge for at least 2 hours. When you're ready to dig in, cut it into eight pieces and add a swirl of fresh whipped cream on each one. Scatter some lime zest on top or add a skinny lime slice to make it look fancy.

Keeping It Fresh

This pie keeps really well. Just cover it with plastic or put it in a container with a lid and it'll stay good in the fridge for up to 4 days. Want to save it longer? Wrap it tight in foil and plastic, then freeze it for up to 3 months. Just move it to the fridge the night before you want to eat it. You can also make this a day early, which comes in handy when you're planning a get-together.
