Key Lime Mousse

Happy St. Patrick’s Day!  I thought I’d share a green dessert to celebrate the holiday {smile}.  Be sure to swing by and pick up your Irish Blessing printables too!  Hope you have day filled with many blessings!

Now, let’s talk a little bit about desserts!  Desserts make everything better, wouldn’t you agree?  Well, certain desserts can make things better for me!  Hee-hee.  Hmmm, like the Key Lime Cheesecake from the Cheesecake Factory, a Hot Fudge Sundae from McDonalds with extra peanuts, the Cookie Monster from Cheddar’s or even a Cinnamon Scone from Starbuck’s.  Those are just to name a few too!  I have a love for desserts — and saving room is a must!

Well, a few weeks ago, I shared a lunch date with the hubs to Houlihan’s.  We ordered their Key Lime Mousse to share.  Friends, it was to die for -and- it was served in a mason jar.  I think that made it even better!  Mason jars are so much fun and incredibly versatile.  Anywho,  it dawned on me that I might be able to make a comparable copycat dessert.  Guess what?  That’s exactly what I did and  it was amazing!  Creamy, tart perfection!  It was so good that I ended up making another batch over the weekend so I could enjoy more than just a taste test due to my diet.

  • 1-1/3 cup sweetened condensed milk
  • ½ cup Key Lime Juice
  • 1 cup heavy whipping cream, whipped
  • Green Food Coloring, optional
  • Lime, optional

Key Lime Mousse
  1. In a large bowl, beat the cream cheese, milk and juice until smooth.
  2. Fold in whipped cream.
  3. Add food coloring to desired color, optional.
  4. Refrigerate overnight (minimum of 3-4 hours)
Crumbled Graham Cracker Crust
  1. Preheat oven to 375-degrees.
  2. Place graham crackers in a gallon-sized Ziploc bag. Remove air and seal tightly. Using a rolling pin, smash the crackers and roll out until you have very fine crumbs.
  3. In a medium-sized bowl, combine crumbs, sugar, and butter until all the crumbs are evenly moist.
  4. Press crumbs into a jelly roll pan.
  5. Bake for 7 minutes in preheated oven.
  6. Allow the crust to completely cool.
  7. Use a spoon to break up the crusts and place crumbles into jars or bowls for serving.

  2. Add Key Lime Mousse.
  3. Garnish with whipped cream and slice of lime.
  4. Sprinkle with additional graham cracker crust, optional.
Serving size: 1 jar
I used Ball Wide Mouth 8 oz mason jars. Feel free to use 4 oz. jars to make your mixture serve a larger crowd.
Feel free to fill the jars and refrigerate overnight. The crust will not get soft.

Key Lime Mousse with livelaughrowe.comDessert in a jar!  Key Lime Mousse with livelaughrowe.comYou could easily serve this Key Lime Mousse without the crumbled graham cracker crust.  Feel free to use the crust recipe your next Graham Cracker Pie Crust too!  You would simply press the crust into your pie pan and bake as shown in the recipe.  Easy peasy!

        Sounds sooo good ! I have some fresh Meyer lemons and I am wondering if I can juice them and use their juice in place of the lime ?

        Thanks for the recipe !

    Just made this- I love the taste of lime in this, and the texture turned out perfectly. What a creative twist on key lime pie! Bringing these to a family gathering tomorrow- I’m sure they will be a hit!

      Update: My whole family LOVED this!! They turned out absolutely brilliantly. Oh my goodness, it is just the right amount of everything! We added whipped cream and dark chocolate sprinkled on top as well to balance out the tart flavor of the key lime. Delicious and I think this will become a family classic!
