Recipe:

- ½ cups Fresh squeezed lime juice (about 3-4 limes)
- Zest from 1-2 limes (about 2 tsp)
- Pinch of salt
Graham Cracker Crust Ingredients:
- 10-12 graham crackers (full piece)
- 15 ritz crackers
- 8 tablespoons unsalted butter (melted)
- ⅓ cup granulated sugar
Directions:
To prepare the graham cracker pie crust: using a food processor- grind the graham crackers and ritz crackers or use a ziplock bag and rolling pin. Add sugar and pinch of salt. Melt the butter and pour into the food processor while on low speed. Or you can mix by hand in a medium bowl. The mixture will be coarse.
Evenly distribute the graham cracker mix two 9” springform pan and firmly press down using either your hands or back of a measuring cup to make sure it is evenly and firmly packed. Bake the crust for 10 minutes or until fragrant and the crust begins to brown. Allow to cool completely before filling. Cooling for 20-30 minutes before adding the filling.
*The crust doesn’t have to be baked- chill in the refrigerator for 2 hours before filling for a no bake crust.
While the crust cools- start making the ice cream batter.
- In a stand mixer with the whisk attachment or hand held mixer on medium speed- beat the heavy whipping cream until medium peaks form. Add the lime juice and beat on low-medium for 10 seconds or until evenly distributed.
- Fold in the sweetened condensed milk, salt and lime zest.
- Evenly distribute the whipped cream mixture to your 2 prepared pans/pie crust.
- Using an offset spatula, ensure that the top of one of the pie’s is flat and smooth. This will be the bottom layer of the cake. Using the offset spatula, create texture on the top of the second pie. This will be the top of the cake.
- Freeze for 8-12 hours
- Stack the two pie layers with the smooth topped pie on the bottom. Add fresh sliced lime to garnish and decorate the ice cream cake!
- Sit at room temperature for 15-20 minutes before cutting and serving! It’s best slightly melted and a bit soft.

The limes in the photos are Persian limes. Key limes are very small and yellow. It would take more key limes to make 1/2 cup of juice.
That is correct- you can use 1/2 cup of any limes of your choice.
Delicious! I used Nellie and Joe’s key lime juice because I couldn’t get fresh key limes and it turned out wonderfully. Thank you!
Thank you for the feedback! I’m glad you found an alternative that worked so well.
