These no bake key lime pie cups are one of my favorite make-ahead desserts for spring and summer entertaining. They’re creamy, tangy, layered with graham cracker crumbs, and topped with whipped cream, lime zest, and a fresh lime slice for a dessert that feels so pretty without being hard to make.
I love these because they solve so many party dessert problems at once. Since they’re made in individual dessert cups with lids, they’re easy to store, easy to transport, and perfect for bringing to a Mother’s Day brunch, baby shower, bridal shower, picnic, beach day, or summer party. They feel special and bakery-style, but they’re actually very simple.
If you love key lime pie but want something easier to serve for a crowd, these mini key lime pie cups are such a good option. No slicing, no messy serving, and no baking. Just layer, chill, top, and bring them wherever you need an easy dessert.

How to Make No Bake Key Lime Pie Cups
Start by crushing the graham crackers. You can place them in a zip-top bag and crush them with a rolling pin until they turn into fine crumbs.
In a bowl, mix together half of the sweetened condensed milk and lime juice mixture until smooth.
In a separate bowl, whip the heavy cream with the sugar and vanilla until medium peaks form. Then fold 1 cup of the whipped cream into the key lime mixture to make the filling light and fluffy.
Set out 8 clear dessert cups. Add 1 1/2 tablespoons graham cracker crumbs to the bottom of each cup. Spoon or pipe in the key lime filling until each cup is about halfway full. Add another 1 1/2 tablespoons graham cracker crumbs, then top with more key lime filling almost to the top.
Transfer the remaining whipped cream to a piping bag or piping tool and pipe a swirl onto each cup. Finish with a sprinkle of graham cracker crumbs, a little lime zest, and a half-moon slice of fresh lime.
Chill until ready to serve.
Make-Ahead Tips
These key lime pie dessert cups are such a good make-ahead dessert because they can be assembled in advance and kept chilled until you need them. I especially love using dessert cups with lids because you can cover them, stack them in the fridge, and bring them right to a party.
They’re perfect for:
- Mother’s Day brunch
- baby showers
- bridal showers
- summer parties
- backyard cookouts
- picnics
- beach days, as long as they stay chilled in a cooler
Storage

Store these no bake key lime pie cups covered in the refrigerator for up to 3 to 4 days. For the best texture, they’re especially good within the first 1 to 2 days. Because they contain dairy, they should not sit out for more than 2 hours, or 1 hour if it’s very hot outside.
Tips for the Best Key Lime Pie Cups
- Use cold heavy cream so it whips up properly.
- Don’t over-whip the cream.
- Fold the whipped cream gently into the key lime mixture to keep it light.
- Dessert cups with lids make these much easier to transport.
- Add the lime slice right before serving if you want the freshest look.
