Why Choose a No-Churn Ice Cream Pie?

  • No special equipment required—no ice cream machine needed.
  • Easy to prepare—simple steps and common ingredients.
  • Classic summer flavors—Key lime’s tangy punch, creamy texture, and a crunchy crust.
  • Impressive presentation—looks and tastes like it came from a pro bakery.

This recipe creatively merges the classic Key lime pie’s flavors with a frozen, mousse-like filling reminiscent of ice cream, yet requires just a whisk and a freezer.

What Makes Key Lime Pie Special?

Key lime pie is an iconic American dessert, especially beloved in Florida where the tiny, aromatic Key limes thrive. Its signature filling combines sharp, aromatic lime juice, sweetened condensed milk, and egg yolks, poured into a graham cracker crust and usually topped with whipped cream. The result: a balance of bright citrus, creamy sweetness, and buttery crunch.

This no-churn ice cream version pays homage to the original with the same fresh lime flavor and crunchy crust—but transforms the experience with a cold, creamy texture perfect for summer.

Recipe Overview: Components of No-Churn Key Lime Ice Cream Pie

  • Graham Cracker Crust: Buttery and crisp, provides the classic pie foundation.
  • No-Churn Key Lime Ice Cream Filling: Creamy, tart, and delightfully smooth.
  • Toppings (Optional): Whipped cream, lime zest, or extra graham cracker crumbs for texture and flair.

Required Ingredients

  • Graham crackers (or digestive biscuits)
  • Unsalted butter
  • Sweetened condensed milk
  • Heavy cream
  • Fresh lime juice (preferably Key limes)
  • Fresh lime zest
  • Pinch of salt
  • Optional: Whipped cream for garnish

Step-by-Step Guide: How to Make No-Churn Key Lime Ice Cream Pie

1. Prepare the Graham Cracker Crust

  • Crush graham crackers into fine crumbs using a food processor or a sealable bag and rolling pin.
  • Mix crumbs with melted butter and pinch of salt.
  • Firmly press mixture into the bottom and up the sides of a 9-inch pie plate.
  • Bake at 350°F (177°C) for 8–10 minutes until golden (optional for more crunch), then cool completely.

2. Mix the Key Lime Ice Cream Base

  • Combine sweetened condensed milk with lime juice and zest; stir until fully blended.
  • In a large bowl, whip heavy cream to medium-stiff peaks using a stand mixer or hand beaters.
  • Fold the lime mixture gently into the whipped cream, being careful not to deflate.

3. Assemble and Freeze

  • Pour the ice cream filling into cooled pie crust.
  • Spread evenly and smooth top using a spatula.
  • Cover loosely and freeze until firm—at least 8 hours, preferably overnight.

4. Garnish and Serve

  • Optional: Decorate with swirls of whipped cream, extra lime zest, or more graham cracker crumbs.
  • Slice with a heated knife for clean cuts.

Tips and Tricks for Success

  • Use cold cream: Chilled heavy cream whips faster and yields better texture.
  • Choose fresh limes: Freshly squeezed juice enhances flavor and aroma.
  • Don’t overmix: Gently fold cream to preserve air for a light filling.
  • Customize crust: Substitute ginger snaps or chocolate cookies for graham crackers for a flavor twist.
  • Freezing time matters: Overnight freezing ensures the pie is set and ready for serving.

Ingredient Spotlight: Why Sweetened Condensed Milk Works

Sweetened condensed milk is essential in no-churn desserts—it provides both sweetness and structure, yielding a smooth consistency even without churning. It creates a stable, scoopable ice cream pie that mimics the creaminess of custard-based pies and the velvet texture of traditional ice cream.

Flavor Variations

  • Lemon or Orange: Swap limes for lemons or oranges for a bright citrus twist.
  • Coconut: Fold in toasted coconut for tropical depth.
  • Chocolate swirl: Drizzle melted chocolate over filling before freezing.
  • Berry surprise: Add a layer of fresh berries beneath the ice cream filling.

Serving Suggestions

  • Serve directly from the freezer for neat slices and sharp flavor.
  • Top with whipped cream, lime zest, or a berry coulis for extra color.
  • Pair with iced drinks or citrus cocktails for a refreshing finish.

How to Store and Make Ahead

  • Wrap pie tightly with plastic wrap or foil; store in freezer for up to two weeks.
  • Individual slices can be pre-cut and stored in airtight containers for grab-and-go desserts.
  • If making ahead for a party, garnish just before serving to ensure whipped cream stays fresh.

Frequently Asked Questions (FAQs)

Q: Can I use bottled lime juice instead of fresh?

A: While bottled lime juice is convenient, fresh lime juice offers brighter, more aromatic flavor. Use bottled only in a pinch, and always check for pure juice—no additives.

Q: Do I have to bake the graham cracker crust?

A: Baking is optional but recommended for added crunch and more robust flavor. If short on time, simply chill the crust—just press firmly so it holds together.

Q: Can I make this pie dairy-free?

A: Substitute coconut cream for heavy cream and use dairy-free sweetened condensed milk. Ensure the flavor profile compliments the lime.

Q: How long ahead can I prepare the pie?

A: The pie keeps well in the freezer for up to two weeks. Garnish just before serving for best results.

Q: What’s the best way to slice frozen ice cream pie?

A: Dip a sharp knife in hot water, wipe dry, and slice through the pie. This creates clean, neat portions without cracking the crust.

Troubleshooting and Advanced Tips

  • Pie won’t firm up: Make sure the freezer is cold enough and that cream was fully whipped before folding.
  • Crust crumbles when slicing: Press crust firmly when making; consider an optional bake for extra bonding.
  • Too tart or too sweet: Adjust lime juice and condensed milk quantities to match your taste preferences.
  • Want extra crunch: Mix chopped nuts into the crust or sprinkle toasted coconut on top.
