These Mini Key Lime Pies are the perfect individual dessert for your next party or group event. Freshly squeezed key lime juice perfectly balances the sweetness of the sweetened condensed milk. Top with fresh-made whipped cream (don’t worry – that recipe is included down below) to give these the perfect finishing touch.
Components and Ingredients
There are three components to this recipe: the graham cracker crust, the key lime filling, and the homemade whipped cream. All of these steps are relatively easy and go quickly. In all fairness, it is a bit tedious to hand squeeze each key lime, but I promise you that you won’t get the same flavor from regular limes or bottled juices. This really is the “key” (pun intended!) to this recipe – so don’t skimp here.
Graham Cracker Crust
The graham cracker crust is made of crushed up graham crackers, light brown sugar, a bit of salt, and a few tablespoons of melted unsalted butter. This is the perfect opportunity to break out your immersion blender to blitz the graham crackers. Check out my recommended immersion blender here. It makes quick and easy work of getting a really fine crumble for the crust. If you don’t have one, you can put the crackers in a zip-top bag and crush them with a rolling pin, tenderizer, or an empty wine bottle. As long as you end up with very finely ground graham crackers, the method you use isn’t very important.
Mix all of these ingredients together until you reach a slightly moist, sandy consistency. Line a muffin tin with paper cups, then place a tablespoon of the crust mixture into the bottoms. Press down on the crust with the bottom of a cup, glass, or measuring cup (anything that will fit) to flatten and compact the crust. Place them in an oven preheated to 350°F for 5 to 7-minutes to set the crusts. The crusts should be dry to the touch and look slightly toasted, but not totally browned.
Key Lime Filling
Freshly squeezed key lime juice takes center stage for this dessert. While it’s possible to use regular limes or bottled juice, you will not get the same punchy, tart, and distinct flavor that fresh-squeezed key limes provide. They are more tart and brighter than regular store-bought limes (which are actually called Persian Limes), and bottled juices are typically made from concentrate. Neither of these options provides the same flavor you get when using fresh fruit.
The filling ingredients consist of sweetened condensed milk (not evaporated milk – these are usually sold next to each other, so be careful you don’t grab the wrong kind), fresh squeezed key lime juice, sour cream, lime zest, and salt. Zest several of the limes, then squeeze them for the juice. Combine all of the ingredients in a bowl, and use a ¼ cup measuring cup to portion the filling into your prepared cupcake pans. You will likely have several unused crusts. Bake for 10 minutes. Remove from the oven and allow to cool to room temperature. Cover and place in the fridge for a minimum of two hours, or up to overnight, to completely set the filling. Be sure to serve these chilled. These can be stored covered in the refrigerator for 4 to 5 days.
Homemade Whipped Cream
Finishing off this dessert with homemade whipped cream really brings this whole dish together. With two ingredients, it’s insanely simple and can be made in a minute or two right before serving.
Add heavy whipping cream and two tablespoons of powdered sugar to your stand mixer or to the bowl of a hand mixer. Whisk with moderate speed until you get medium stiff peaks, about 2 to 3-minutes. You can make this ahead of time if desired. This will store in an airtight container for a day or two in the fridge until you are ready to serve.
Right before serving, top each pie with a dollop of whipped cream (or use a piping bag if you are feeling fancy!), then sprinkle with some lime zest and a small pinch of granulated sugar.

I have made these a few times and they are always a hit! Perfectly tangy and sweet!

Thank you Amy! Happy to hear that you liked them!

I like this recipe! However, I found I only needed one pound of key limes and two bags of graham crackers gave me about double the amount of crumbs I needed!
Spencer Klickman
I’m glad you liked the recipe! That’s interesting to hear about the limes. The ones in our grocery store are about 1-inch in size. It’s possible it could take less limes if yours are bigger. I’ve made this several times while testing the recipe, and it has always taken about two pounds of 1-inch limes to get the amount of juice indicated. I’ll update the recipe to include the actual size of the limes that I use.
I’m also aware that the graham crackers will yield more crust than is actually needed for the filling. I’m currently working on getting those amounts more precise in order to eliminate any waste. I’ll be sure to update the recipe soon!
Thank you for your feedback!
