Why You’ll Love This
This would be a great dessert to treat your mom on Mother’s Day or for a crowd-pleasing Easter dessert.
Seriously it doesn’t get much easier than this pie recipe!
A few simple ingredients are whisked together and poured into the crust, and baked for about 10 minutes.
The most time-consuming part is squeezing those little key limes. It usually takes about 17-18 Key limes for me to produce a 3/4 cup of juice.
This Key Lime pie receives rave reviews every time I serve it to my guests.
See the recipe card below for a full list of ingredients and instructions.
- Key Lime Juice – Key limes are tarter than regular Persian limes, giving this pie much more flavor.
- Sweetened Condensed Milk – The condensed milk is what makes this pie set up without using eggs. You will need two 14-ounce cans.
- Sour Cream – Sour cream adds a rich, thick texture and a little tangy flavor to the pie.
- Graham Cracker Crust – A homemade graham cracker crust is super easy to make, but you can also use a store-bought pie crust.
- Whipped Cream – Use our homemade whipped cream or store-bought.
Easy Key Lime Pie
Ok, so you know the drill for preparing a homemade graham cracker crust, right?
Preheat oven to 350 degrees F.
In a medium bowl, mix the graham cracker crumbs, melted butter, and sugar until moist and combined. Press the crumb mixture into the bottom and sides of the pie pan. Bake the crust for 8-10 minutes.
In a large bowl, stir the sweetened condensed milk, sour cream, key lime zest, and fresh lime juice until smooth.
Pour the Key lime pie filling into the prepared graham cracker crust.
Bake for 10-15 minutes until tiny bubbles start to form on the surface. Remove and cool to room temperature on a wire rack.
Chill for at least 3 hours before serving; overnight is best.
When ready to serve, whip the heavy cream, powdered sugar, and vanilla together until it forms stiff peaks. Garnish as desired.
I use the stand mixer with the whisk attachment to make this step easier.
I use a piping bag fitted with a large star tip to decorate the pie with whipped cream and sprinkle a little extra grated lime zest over the top.
Serve and enjoy this delightful, super easy eggless Key lime pie!
- I beg of you to use fresh Key lime juice for the best Key Lime pie. It makes all the difference in this pie. Most grocery stores carry fresh Key limes.
- Choose plump limes that give a little when you squeeze them. They will produce more lime juice.
- Zest the limes before you juice them.
- You can use a store-bought graham cracker pie crust instead of making a homemade crust.
- You can also use a traditional pie crust, but a graham cracker crust is so easy to prepare.
- Be sure to chill the pie for at least 3 hours before serving.
- You can substitute full-fat Greek yogurt for sour cream.
- You ‘can’ use regular lime juice or bottled Key lime juice, but the flavor will be slightly different.
- You can use store-bought whipped cream instead of homemade whipped cream.
- If using graham crackers, pulse them in a food processor until crumbs are formed.
Yes. This pie will keep well for 48 hours in the fridge. I recommend not garnishing with whipped cream until ready to serve. The whipped cream can weep after it sits for a bit.
Cover the cooled pie tightly with plastic wrap and refrigerate for up to 3 days.
Yes, but don’t garnish the pie with whipped cream. Wrap the pie tightly with plastic wrap and then with aluminum foil. Freeze for 1 to 2 months for the best quality. Thaw in the refrigerator overnight.
