I love how this ice cream combines the creamy richness of homemade ice cream with the tart, refreshing flavor of key lime pie. Sweetened condensed milk balances the citrus beautifully, while heavy cream and whole milk give me a smooth and creamy base.
I also enjoy the crushed graham crackers throughout the ice cream. They bring in the familiar flavor of a graham cracker pie crust and give each serving a little extra texture.
Another reason I make this recipe is the simple no-cook preparation. I only need to whisk the base together, chill it, churn it, and freeze it until firm. There are no eggs to temper and no custard to cook on the stove.
Ingredients
(Note: All ingredient amounts are listed in the recipe card below.)
1 1/2 cups Whole Milk
1/2 cup Key Lime Juice
Zest of 1 Lime
1/2 cup Heavy Cream
Dash of Salt
1 (14-ounce) can Sweetened Condensed Milk
6 Graham Crackers (1 1/2 cookie sheets), coarsely crushed, divided
Graham Cracker Pieces
Key Lime Wedges or Lime Zest
Directions
I add the whole milk, key lime juice, heavy cream, salt, and sweetened condensed milk to a large bowl. I whisk everything together until thoroughly combined. I also incorporate the lime zest so its fresh citrus flavor is distributed throughout the base.
I cover the bowl containing the ice cream base with a lid or plastic wrap. I transfer it to the refrigerator for 4 hours or up to overnight. Although this chilling step is not required, I prefer it because starting with a thoroughly chilled base helps during churning.
Once chilled, I pour the key lime ice cream mixture into my ice cream maker. I churn it according to the manufacturer’s instructions, typically until the mixture has a thick, soft-serve-like consistency.
After churning, I stir 1/3 cup of the graham crackers into the ice cream. I spoon the ice cream into a freezer-safe container, cover it, and freeze it for 1 hour or until firm.
When I am ready to serve, I sprinkle each portion with 1 teaspoon of graham crackers.
I finish each serving with key lime wedges or lime zest for a fresh citrus garnish.
Servings and Timing
This recipe makes 6 servings.
Yield: 6
Prep Time: 5 minutes
Churning Time: 30 minutes
Freezing Time: 1 hour
Total Time: 1 hour 35 minutes
I keep in mind that the optional but recommended refrigeration period of 4 hours or up to overnight is not included in the listed total time. If I choose to chill the base before churning, I plan accordingly.
Variations
I can make this ice cream even more reminiscent of key lime pie by adding extra coarsely crushed graham crackers. I like reserving some for serving so every bowl gets a fresh, slightly crunchy topping.
For more citrus intensity, I can garnish each serving with additional lime zest. I find that fresh zest adds plenty of lime aroma without changing the texture of the ice cream.
If I want more texture, I can create layers of graham cracker pieces as I transfer the churned ice cream to its freezer container. This gives me little pockets of graham cracker flavor throughout each scoop.
I can also serve the ice cream in small bowls with lime wedges and extra graham cracker pieces on top. For a fun presentation, I like crushing graham crackers more finely and sprinkling them generously over each serving to mimic a pie crust.
Storage/Reheating
I transfer the churned key lime pie ice cream to a freezer-safe airtight container before freezing it until firm. Keeping the container tightly covered helps protect the ice cream from absorbing other freezer odors and reduces the formation of ice crystals.
For the best texture and flavor, I prefer enjoying homemade ice cream within about 1 to 2 weeks. It can remain frozen longer when properly stored, but its texture may gradually become firmer or icier.
If my ice cream becomes very firm in the freezer, I don’t reheat it. Instead, I place the container at room temperature for about 5 to 10 minutes before scooping. This gives the ice cream enough time to soften slightly while keeping it frozen.
I also keep the container toward the back of my freezer when possible, where the temperature tends to remain more consistent than near the door.
FAQs
Do I need to cook the key lime pie ice cream base?
No. One of the reasons I enjoy this recipe is that the base requires no cooking. I simply whisk the ingredients together, chill the mixture if desired, and transfer it directly to my ice cream maker.
Do I have to chill the ice cream mixture before churning?
The chilling step is not required, but I recommend it. I can refrigerate the covered base for 4 hours or up to overnight before churning. I find that beginning with a cold mixture makes the churning process more effective.
Can I make key lime pie ice cream without eggs?
Yes. This recipe does not require eggs. I use sweetened condensed milk, whole milk, and heavy cream to create the creamy base, which means I don’t need to prepare a traditional cooked custard.
Why does this ice cream use sweetened condensed milk?
I use sweetened condensed milk to provide both sweetness and richness. It pairs particularly well with the tart key lime juice and helps give the no-cook ice cream base its creamy character.
When should I add the graham crackers?
I add 1/3 cup of graham crackers after the ice cream has finished churning. I stir them into the ice cream before transferring it to a freezer-safe container. I reserve additional graham crackers for sprinkling over individual servings.
How long should I churn the ice cream?
The listed churning time is 30 minutes, but I always follow the instructions for my particular ice cream maker. Different machines can require slightly different amounts of time.
How long does key lime pie ice cream need to freeze?
After churning, I transfer the ice cream to a covered freezer-safe container and freeze it for about 1 hour or until firm. If I prefer firmer scoops, I can leave it in the freezer longer.
What can I use to garnish key lime pie ice cream?
I like using graham cracker pieces, key lime wedges, or fresh lime zest. The graham crackers reinforce the key lime pie flavor, while the fresh lime garnish adds color and a bright citrus aroma.
Why is my homemade ice cream too hard to scoop?
Homemade ice cream can become quite firm after spending several hours in the freezer. When that happens, I leave it at room temperature for about 5 to 10 minutes before scooping rather than trying to scoop it immediately.
Can I make key lime pie ice cream ahead of time?
Yes. I actually find this recipe convenient to prepare ahead because the base can be refrigerated before churning, and the finished ice cream needs freezer time to firm up. I keep the finished ice cream tightly covered in a freezer-safe container until I am ready to serve it.
Conclusion
This key lime pie ice cream is a dessert I love for its balance of creamy sweetness, tart citrus, and graham cracker flavor. The no-cook base keeps preparation simple, while key lime juice and fresh zest give every scoop the refreshing flavor I expect from a classic key lime dessert.

Instructions
Add the whole milk, key lime juice, lime zest, heavy cream, salt, and sweetened condensed milk to a large bowl. Whisk until thoroughly combined.
Cover the bowl with a lid or plastic wrap and refrigerate for 4 hours or up to overnight if desired. Chilling is optional but helps the mixture churn efficiently.

Notes
Chilling the ice cream base for 4 hours or overnight before churning is optional but recommended for best results.
For additional graham cracker flavor and texture, layer extra crushed graham crackers into the ice cream as it is transferred to the freezer container.
Extra fresh lime zest can be added as a garnish for a stronger citrus aroma.
Store the ice cream tightly covered in a freezer-safe airtight container, preferably toward the back of the freezer where the temperature is more consistent.
For the best texture and flavor, enjoy within 1 to 2 weeks.
If the ice cream becomes too firm to scoop, leave it at room temperature for 5 to 10 minutes before serving.
