The backstory.

This is my husband's absolute favorite key lime pie-and since he requests it A-LOT during the summer, I had to find a way to make it without heating up the whole kitchen. So I adapted it for the crockpot, and honestly? I might never go back. Same creamy, tangy filling and buttery crust we love, just made easier (and cooler) with the slow cooker.

It's a must make.

When dessert is this simple and this good, there's no reason not to make it on repeat:

• Crockpot convenience - no oven needed, just mix and let it slow cook.
• Make-ahead dessert - prepare in advance and refrigerate for stress-free serving.
• Delicious flavor - tangy key lime juice balances the sweetness of condensed milk for just the right zing.
• Crowd pleaser - chilled lime pie topped with whipped cream is perfect for summer gatherings.

What you'll need.

Here are the ingredients you will need to make this slow cooker key lime pie:

• Graham crackers: crushed into cracker crumbs to form the crust with butter and sugar.
• Butter: melted to bind the graham cracker crumbs together for the base.
• Sweetened condensed milk: essential for the rich, creamy filling.
• Sour cream: helps balance the sweetness and adds a silky texture.
• Key lime juice: fresh or bottled, it provides the signature tang.
• Lime zest: brightens the filling with citrus aroma.

Customize it your own way.

This key lime pie in the slow cooker is delicious as-is, but here are creative ways to mix it up:

• Swap graham cracker crumbs with gingersnaps for spice.
• Use vanilla wafer crumbs in place of graham crackers for a sweeter crust.
• Add shredded coconut to the crust for tropical flair.
• Stir in cream cheese for a cheesecake-style pie.
• Drizzle white chocolate over the top for indulgence.
• Swirl in raspberry purée for fruity contrast.
• Add sea salt to the crust for a sweet-salty balance.
• Top with toasted coconut or candied nuts for crunch.
• Try lemon juice instead of lime juice for a citrus twist.
• Bake as a mini version in ramekins lined with parchment paper.

Kori's tips.

• Always use a towel under the lid to prevent condensation from dripping onto the pie.
• Don't skip the chilling time-it ensures the pie sets properly.
• Use parchment paper if baking directly in the crock-it makes removing the pie easier.
• Watch closely at the end of the cooking time-look for bubbles, not browning.
