Prep Time 1 hour hr 15 minutes mins
Cook Time 14 minutes mins
Total Time 1 hour hr 30 minutes mins
- 1 ½ cups graham cracker crumbs about 12 full sheets, crushed
- ⅓ cup granulated sugar
- 6 Tablespoons butter melted
- 2 14 oz cans sweetened condensed milk
- 4 oz cream cheese softened
- ¾ cup key lime juice
- Zest of 2 regular limes or 4 key limes
- Fresh whipped cream for topping (optional)
Make the crust: Combine the graham cracker crumbs, sugar, and melted butter. Press firmly and evenly into an 8-inch square baking pan.
Bake the crust at 350°F for 10 minutes. Let it cool before adding the filling.
Make the filling: Beat the softened cream cheese until smooth. Add both cans of sweetened condensed milk, the key lime juice, and the lime zest. Mix until smooth.
Pour the filling over the cooled crust and bake at 350°F for 10 minutes.
Cool at room temperature for about 30 minutes, then refrigerate for at least 3 hours before serving.
Top each square with a dollop of fresh whipped cream, if desired.
Lime juice: Juice about 20 small fresh key limes, OR use a bottled key lime juice (such as Nellie & Joe's), available at most grocery stores.
Chill time: The 3-hour minimum chill is separate from the listed prep/cook time. For the firmest, cleanest slices, chill overnight.
Make ahead: Bars keep up to 3 days in the fridge. The crust can be made several days ahead and stored at room temperature or chilled.
Freeze: Cover the pan tightly with plastic wrap and foil; freeze up to 3 months. Thaw overnight in the fridge before serving.
Feeding a crowd: Double the recipe and bake in a 9×13-inch pan.
