What You'll Need for this Recipe

Key Limes, of course. Some folks will say there's no noticeable difference between key limes and regular limes but real ones know! Although they're much smaller, which means you'll need to use more of them, they're worth the effort. And as tiny as key limes are, they have the nerve to have a lot of seeds we're not trying to juice endless amounts of them so to boost the flavor factor, we are also using the key lime zest, which adds stronger taste and pretty green flecks of color to the ice cream.
If you can't find key limes or they're out of season, you can make this frozen dessert with regular limes just note the flavor will be slightly different.
Warming Spices like cinnamon and ginger add depth of flavor to graham cracker crust. While not part of the traditional key lime pie ice cream recipe, I highly recommend this twist because it's so easy and gives a lil' something extra that makes the ice cream unforgettable.

Substitutions & Variations
Graham Crackers or pre-made crumbs can work here depending on what's available to you and your preference. A pre-baked graham cracker crust can also work but you won't be able to add the spices with this option. They all work the same once you crush the graham crackers.
Vegan - Use plant-based sweetened condensed milk, cream--like coconut cream--and butter, as well as dairy-free and eggless graham crackers to make this vegetarian recipe vegan.
How to Make Key Lime Pie Ice Cream without an Ice Cream Maker

- Step 1: Mix up the graham cracker crumbs, spices, brown sugar, and butter.

- Step 2: Press the mixture into the bottom of a pan and bake until golden.
Pro Tip #1
This step can be done up to three days ahead of time. Just store the crust in an airtight container and refrigerate it.

- Step 3: Whip the heavy cream into whipped cream.

- Step 4: Zest and juice the limes then mix with sweetened condensed milk and vanilla extract, and combine with whipped cream.

- Step 5: Layer the ice cream base and graham cracker crust in a container then place it in the freezer.

- Step 6: A few hours later, it's ready!
Pro Tip #2
I like to bake the crust and make the ice cream in the same loaf pan, which makes for fewer dishes. Also, I recommend breaking up the graham crust and leaving half on the bottom of the pan then sprinkling the rest on top of the ice cream base. This will provide a bit of crust in every scoop!
Frequently Asked Questions
This ice cream can last in the freezer for up to six months, but the texture may become more icy after around one month.


How to Serve
Serve this treat ice and cold--just thaw it for a couple of minutes before scooping. Add whipped cream and a piece of graham cracker for extra razzle dazzle.
You can serve key lime-pie flavored ice cream in a bowl or cone but I personally love making ice cream sandwiches with a scoop of the ice cream and two graham crackers.
And key lime flavor is not just for desserts! Try mixing up my key lime margarita next.
