Ingredients

  • 8 ounces cream cheese softened
  • 1 14 oz can sweetened condensed milk
  • ¾ cup key lime juice
  • 1 8 oz. tub Cool Whip or whipped cream - see notes
  • 1 box graham crackers 3 sleeves

Topping

  • 1 8 oz. tub Cool Whip fresh whipped cream or cream cheese whipped cream also work - see notes
Makes: 9 x 13inch rectangle

Instructions

  • In a large bowl, whip 8 ounces cream cheese until it is creamy and lump free.
  • Mix in 1 14 oz can sweetened condensed milk a little bit at a time, until it is fully incorporated.
  • Add the ¾ cup key lime juice and mix until uniform.
  • Fold in 1 8 oz. tub Cool Whip.
  • Layer 1 sleeve of graham crackers on the bottom of a 9x13-inch pan. Top with half of the key lime mixture.
  • Repeat with another layer of graham crackers, the rest of the key lime mixture, and the last layer of graham crackers.
  • Spread 1 8 oz. tub Cool Whip or the topping of your choice over the top of the graham crackers.
  • Cover and chill for at least 4 hours (overnight preferred) before cutting into slices and serving.

Notes

  • You can use regular lime juice instead of key lime juice if you want to.
  • If you are juicing fresh limes, save a little bit of zest to sprinkle over the top.
  • If you prefer to use fresh whipped cream, replace each tub of Cool Whip with 1½ cups heavy cream, 3 Tablespoons of powdered sugar and 1 teaspoon of vanilla extract.
  • I also like using cream cheese whipped cream as the topping. The cream cheese adds both flavor and stability to the mix. 
  • You could also spread a tub of partially melted vanilla frosting over the top to mimic an eclair cake more closely.
