This No-Churn Key Lime Pie ice cream is the creamiest, easiest, and most refreshing treat you’ll ever make. No ice cream maker needed!

This ice cream is tart and sweet, super creamy, with lime and chunks of graham crackers. It’s like eating a Key Lime Pie but in frozen form!

Ingredients you’ll need

This easy ice cream needs some pretty basic ingredients that you probably already have at home:

Heavy whipping cream: When whipped, it creates air‑filled volume and a light texture that mimics the creaminess of churned ice cream without the machine.
Sweetened condensed milk: Adds sweetness and a smooth base that helps prevent ice crystals, so the ice cream stays creamy and scoopable.
Key lime juice: Provides the bright, tangy citrus flavor that makes this taste like a true key lime pie in frozen form.
Key lime zest: Adds concentrated lime aroma and flavor — the zest gives a fresh punch that complements the juice perfectly.
Vanilla extract: Enhances and rounds the citrus notes, giving depth to the overall flavor without overwhelming the lime.
Salt: A small amount brings out the sweetness and citrus, balancing flavor and making each bite more interesting.
Graham crackers (crumbled): Mimic the pie crust texture of a key lime pie — the crunchy bits contrast the creamy ice cream and bring that nostalgic pie‑feeling

Instructions

Chill your heavy whipping cream so it whips up easily. Using a stand mixer or hand mixer, whip the cream until it reaches soft to medium peaks — you want it visibly thick and holding shape, but still smooth and slightly glossy (this helps keep the final texture airy).

In a large mixing bowl, combine the sweetened condensed milk, key lime juice, key lime zest, vanilla extract, and salt. Stir until everything is well‑blended and smooth — the mixture may look a bit thin at first, but it will integrate well.

Take about half of the whipped cream and fold it gently into the lime‑condensed milk mixture. Use a spatula and cut through the center, then lift and fold — this helps keep the air in. Add the remaining whipped cream and fold until thoroughly combined, making sure there are no streaks of plain cream.

Gently fold in the crumbled graham crackers so they’re distributed fairly evenly throughout the mixture — you don’t want to crush them too much, so you retain some texture contrast.

Pour the mixture into a freezer‑safe container (a loaf pan or shallow freezer dish works well). Smooth the top with a spatula. If you like, sprinkle additional graham cracker crumbs over the top for a crust‑like finish.

Cover tightly with plastic wrap or a lid. Freeze for at least 6 to 8 hours (overnight is best) until firmly set.

Remove from the freezer and let rest 5–10 minutes at room temperature before scooping — this helps soften it just enough for easier scoops. Serve in bowls or cones, and garnish with extra lime zest or graham cracker crumbs if desired.

Expert Tips

Chill your bowl and beaters for the cream if you can — the colder they are, the faster your cream will whip and the more stable the peaks.
Whip to medium (not overly stiff) peaks: this ensures the mixture remains light and airy; if you over‑whip to extremely stiff peaks, you may lose some of the lightness and end up with a denser texture.
Use fresh lime juice and zest rather than bottled for the best flavor; the fresh zest especially makes a big difference.
After folding in the whipped cream, don’t over‑stir — keeping as much air as possible gives the best soft texture.
For best scoopability, let it freeze overnight and serve after letting it soften slightly at room temperature — very cold ice cream straight from the freezer can be too hard.
If you like a more crusty texture, reserve a little of the graham cracker crumbs to sprinkle just before serving so you get a fresh crunch.

Frequently Asked Questions

What does No-Churn mean?

No-Churn ice cream means there’s no need to use an ice cream machine to make your ice cream with a creamy and soft consistency.

Usually, you use sweetened condensed milk and whipped cream as a base to obtain the creaminess after freezing. This makes it convenient, easy, and quick to make.

What’s the difference between key lime and Lime?

The key lime, also known as “Mexican lime”, is smaller, more acidic, thinner, and has a stronger aroma than the regular lime. It has a lighter yellow color when ripe and contains more seeds. They don’t store as well as regular limes; therefore, try to use them within 2-3 days.

I like this recipe more with key limes, but if you can’t find them, just go ahead and use regular limes. Overall, the flavor will be almost the same, and you won’t be disappointed.

How long will the ice cream keep in the freezer?

When stored in a well‑sealed container, it should keep for several months. That said, for optimal texture and flavor, I recommend enjoying within 1‑2 months.

Why did my mixture separate or look watery after adding lime juice?

If the lime juice is added too vigorously or before the cream is folded in properly, the mixture can look slightly separated. Keep mixing gently until it smooths out, then proceed to fold in the whipped cream.

Can I add mix‑ins like chocolate or nuts?

Definitely — while the graham cracker crumbs give the classic pie‑crust experience, you could fold in chopped toasted pecans or bits of white chocolate for a twist. Just fold them in gently so you don’t deflate the mixture.
