Served this last night at a dinner party. Everyone loved it, a perfect dessert for a hot summer evening and I don’t think I have ever made a dessert recipe as easy as this before.

I like to serve this mousse in mini dessert dishes, but small Mason jars are fun too. Really, any small dessert dishes, bowls, jars, or even drinking glasses will work.
I can get 10-12 small servings from this recipe, but it really depends on the size of serving dish you use.
For a gluten-free version, simply omit the graham cracker crust–or if you’re like my husband and don’t care for graham cracker crust. It’s always nice to have gluten-free options, and this recipe makes it easy.
This dessert is perfect for any spring celebration, from Easter to Mother’s Day. And it’s so elegant looking and tasty, no one will believe how easy it is to make.
This was delicious! So very rich and fruity. I was excited to make it for my St. Pat’s bunco. It was a hit!

I like to garnish this mousse with lime wedges, but it’s also pretty and delicious served with fresh berries and mint.

I wonder how far in advance can you make this without it collapsing or separating?

How far in advance can you make this ?
Danelle
I would say a day or two.

Just made this with Mexican limes my husband bought at the supermarket. So delicious! I actually left out the Graham cracker crumbs to save a calorie or two and we loved it.
Danelle
Wonderful! Thank you.

Your recipe has become one of my “go-to” quickies for dessert. When serving guests who are gluten-free, i substitute almond or coconut flour for the Graham crackers. Most of the year we have an abundance of Key Limes from our tree so its a perfect way to use them. 5/5!
Danelle
Thank you! It’s my go-to gluten free dessert as well. So glad you like it!

This was delicious! So very rich and fruity. I was excited to make it for my St Pat’s bunco. It was a hit! I’m thinking of experimenting to adapt this for chocolate mousse.
Danelle
Awesome, thank you! If you come up with a chocolate version, I’d love to hear about it. Or, the Easy Chocolate Mousse recipe on my site is truly easy and never fails me. Good luck!

Years ago, I was taught a fail-proof chocolate mouse, just like this.
Beat a pint of heavy or whipping cream to stiff peaks and fold in one bag of melted and cooled semisweet chips. Chill immediately.
Works every time.

This is my new go-to dessert. It’s simple and delicious!
Danelle
Thank you!

I did not have any curdling issues. This was excellent!!! We made this for a recent beach trip and used animal crackers for dipping.

won’t the key lime juice curdle the condensed milk? really want to try it out but I’m skeptic about this part 😛

I’ve never had an issue with that. It’s a pretty common combination in lemon and key lime pie recipes.
The sweetened condensed milk just doesn’t react the same way as regular milk, so it should be fine!

I love key lime and this looks terrific. Nice post!
