Ingredients

For the Crust
  • 1 ½ cups Graham cracker crumbs about 11 full size crackers
  • 2 Tablespoons granulated sugar
  • ⅓ cup unsalted butter melted
For the Topping
  • 6 ounce cream cheese room temperature
  • 14 ounce can sweetened condensed milk
  • 4 large egg yolks
  • 1 Tablespoon key lime zest
  • ½ cup key lime juice juice of 4-5 limes
  • ½ teaspoon vanilla extract
For the Garnish
  • limes
  • lime zest
  • Whipped Cream

Instructions

    Cup of Yum
  1. Preheat oven to 325℉. Line a 9”x9” baking dish with parchment paper.
  2. In a food processor, pulse graham crackers (about 11 full size crackers) to make 1 ½ cups.  Combine the graham cracker crumbs and the granulated sugar. Add the melted butter and stir until combined. 
  3. Using your spoon or your hands, firmly press the mixture into a 9 x 9 baking dish.
  4. Bake crust for 10 minutes. After baking, remove the baking dish from the oven and increase the temperature to 350℉.
  5. In a large mixing bowl, beat cream cheese and sweetened condensed milk with a mixer until smooth.  Add egg yolks, one at a time, mixing well after each addition. Add lime zest, juice and vanilla extract. 
  6. Pour filling over the hot crust and return to the oven to bake for an additional 15-20 minutes. The filling should jiggle slightly in the center when shaken. It should be firm to the touch, but should not be brown. It will continue to solidify as it cools. 
  7. Cover and chill in the refrigerator for 4 hours or until ready to serve.
  8. Garnish with lime slices, lime zest and whipped cream.

Notes

  • Key Limes- Key limes can be hard to find, so if you're not able to track them down you can use regular limes instead. The flavor won't be exactly the same but they'll still be tasty! Look for limes that are plump and juicy. You will need 4 to 5 limes for this recipe.
  • How to garnish. Serve bars with a dollop of whipped cream and a slice of lime. Grate a bit of lime zest on top for a special touch.
  • Storing. These bars keep well covered and refrigerated for up to 5 days. Can also be frozen in airtight container.
  • Do not overbake! The center of the bars should still be a bit jiggly and not browned when you take them out of the oven. The bars will continue to set as they cool.
