3 Ingredient Key Lime Pie
This key lime pie is tangy, sweet and creamy. It is just 3 ingredients and features a no bake filling that doesn't require any eggs. This is a very easy, stress-free pie to make for a cool and refreshing dessert.
Ingredients
- 1 frozen pie crust
- 1 cup (8 fl oz/237 ml) lime juice, see note
- 2 (14 oz) cans full fat sweetened condensed milk
Instructions
- Preheat the oven to 375°F (191°C). Let pie crust soften to room temperature, about 10-15 minutes. (Most frozen pie crust brands recommend a higher baking temperature in their instructions, usually 400°F, but I found that baking at a lower temperature for a few extra minutes helps prevent too much shrinkage).
- Use a fork to prick the bottom of the pie crust several times (I did about a dozen times). You want there to be holes fairly evenly spread across the bottom. This will prevent the pie crust from puffing up during baking.
- Bake pie crust for about 15 minutes or until golden brown and cooked. Let pie crust cool fully.
- While crust is cooling, prepare the filling. Add lime juice and condensed milk to a large mixing bowl. Whisk until lime juice is fully incorporated. Your mixture should be thick, like a pudding.
- Once crust is fully cooled, pour the filling into the crust. Place pie in the fridge for several hours (at least 2-3 hours) to set. I like to refrigerate overnight. Keep pie in the fridge until ready to serve. You can also decorate the pie with fresh whipped cream before serving.
Notes
- This recipe uses two full (14 oz) cans of sweetened condensed milk, or a total of 28 oz. 28 oz refers to weight and not volume.
- For the most authentic key lime pie, you want to use juice from key limes. However, you can use regular limes. You can also use store bought lime juice. There are brands that sell pure key lime juice but they are harder to find at the grocery store. If using store bought, make sure that the only ingredient is lime juice. Just because it is labeled "100% lime juice" does not necessarily mean there aren't other ingredients in the bottle so make sure to check the nutrition label. I have made this pie successfully with Santa Cruz Organic 100% lime juice and Whole Foods 365 Organic Lime Juice. The RealLime brand will not work.
- I like using Wholly Wholesome* or Marie Callender's* frozen pie crust which comes already preshaped in a pie baking pan. You want to use pie crust already shaped in the pie pan because there will be much less shrinkage when it is baked.

- Dairy-free condensed milk substitutes like oat milk or coconut condensed milk will not work. The pie filling thickens up because of the interaction of the acid from the limes and the milk protein in the condensed milk.
