- 11 graham crackers
- ⅓ cup white sugar
- ½ teaspoon cinnamon
- ½ cup key lime juice. (It MUST be key lime! This can be found in the cocktail section of the grocery store, or you can order it online. I always get the brand Nellie and Joe’s.)
- 1 can sweetened condensed milk (in the baking aisle of the grocery store)
- 6 tablespoons melted butter
- 2 tablespoons sour cream
- An egg
đź’ˇ Frugal Tip
This pie is already very inexpensive to make! But to save even more, look for sweetened condensed milk at Aldi. Their store brand is just fine! If you are picky and like eagle brand, you can get a case of 6 at Costco as well.
❤️ Let’s make it together
Making the graham cracker crust
First of all, you can of course buy a pre-made graham cracker crust. I won’t judge you. But it’s really easy to make your own!
Preheat the oven to 375 degrees with the rack in the center.
Just crush the graham crackers in your food processor until they look like, well, crumbs. You may need to break up some stubborn pieces with your hands. Then add the sugar, cinnamon, and melted butter. Pulse a few times until the mixture looks like damp sand.
Pour it into your pie dish and gently press, making sure you cover the bottom and the sides. Bake the crust by itself for 7 minutes. It will not brown, but don’t overtake or it will be very hard to cut.
Let it cool to room temperature. While it’s cooling, make the filling!
Making the filling and baking the pie
The hardest part is over. To make the filling, just mix the sweetened condensed milk, the key lime juice, the sour cream, and the egg. Combine them well, and then cover and chill the filling while the crust finishes cooling.
Once the crust is ready to fill, preheat the oven to 350 with the rack in the center.
Pour the lime filling in and smooth it out with a spatula or wooden spoon. Bake the pie for 10 minutes to set the filling. Allow it to cool to room temperature, then cover it and chill it in the fridge for at least 3 hours
Making and piping the whipped cream topping
Once the pie is chilled, let’s make the whipped cream! Don’t let homemade whipped cream scare you, it couldn’t be easier.
Start with cold heavy cream and put in the bowl of your mixer and fit it with the whisk attachment. Add the vanilla, sugar, and cream of tartar. Turn the mixer on high and beat for 1-2 minutes until the cream is fluffy and beautiful.
Now to get it on the pie, you can either dollop it on and spread it out flat, or you can get fancy and pipe it.
The pie will hold just fine in the fridge a few more hours if you want it ready to go, or you can serve it right after topping.
