Ingredients
For the crust:
12 full-size graham cracker sheets (about 6½ oz), crushed into fine crumbs
2 tablespoons granulated sugar
½ teaspoon kosher salt
8 tablespoons (1 stick) unsalted butter, melted and cooled
For the filling:
8 ounces cream cheese, room temperature
¾ cup boiling water
1 (3-ounce) box lime gelatin mix
1 (14-ounce) can sweetened condensed milk
½ cup bottled or fresh Key lime juice (about 10 Key limes)
¼ teaspoon kosher salt
Whipped cream (optional, for topping)
Instructions
- Prepare the crust:
- Line an 8×8″ pan with parchment paper, creating a sling with 2 sheets.
- Crush the graham crackers into fine crumbs.
- Stir in sugar and salt, then mix in melted butter until evenly moistened.
- Press firmly into the pan, reaching corners and edges.
- Make the filling:
- Whisk gelatin mix into ¾ cup boiling water until dissolved. Let cool ~5 minutes in fridge—don’t let it set.
- Process room‑temp cream cheese, condensed milk, key lime juice, and salt until smooth.
- With the food processor running, pour in the cooled gelatin and blend until fully incorporated.
- Assemble bars:
- Pour the filling atop the crust, smoothing the surface.
- Cover and refrigerate until firm—about 6 hours or overnight is best.
- Serve:
- Carefully lift the chilled dessert from the pan using the parchment paper sling and place it on a cutting board.
- For clean, professional-looking slices, use a sharp knife and wipe it clean between each cut.
- Optionally, top with a swirl of whipped cream before serving.
Notes
Ensure cream cheese is at room temperature for a smooth filling.
Don’t let gelatin sit too long before blending—it should be cool but still liquid.
For extra lime punch, add zest to the filling or crust.
Store chilled and covered for best texture.
