  • 1 package cream cheese softened 8 oz package
  • 1 can sweetened condensed milk 14 oz can
  • 1 container frozen whipped topping 12 oz container, thawed
  • 1 cup fresh key lime juice **See note


  • In a large mixing bowl, combine the softened cream cheese, sweetened condensed milk and thawed whipped topping and mix with your electric mixer until well combined.
  • Add the key lime juice and mix well until the mixture is thick and smooth.
  • Note: You can substitute juice squeezed from regular or Persian limes or 1 cup of frozen limeade in a can for the key lime juice called for in this recipe. If you want to be authentic and use key limes it will take the juice of about 20-24 key limes or a little more than a pound of key limes to make 1 cup. If you are using key limes, use a clean metal garlic press to make squeezing out the juice easier. I have to confess that I used 1/2 cup of frozen limeade and 1/2 cup regular lime juice when I made it because that's what I had on hand, and I couldn't see myself squeezing all of those tiny key limes...
  • Pour into 4 individual serving bowls or parfait glasses and chill thoroughly in the refrigerator before serving. Enjoy


**For a Key Lime Mousse Pie, simply pour the mixture into a pre-made graham cracker pie crust and chill before serving.
