Key Lime White Chocolate Mousse

Key Lime White Chocolate Mousse

Who doesn’t love a holiday where the primary foodΒ groups are salsa and margaritas?

Nothing screams Cinco de Mayo more than lime. Or key lime. So I’m doing it up today with this mousse! As it turns out, key lime isn’t just about pie.

This past week has been all about prepping kids for the upcoming AP tests. If you have a teenager in an AP class, you know what I’m talking about. If you don’t, then you clearly don’t care. And that’s fine! I didn’t care either, once upon a time.

Key Lime White Chocolate Mousse

When I was in high school, I made a choice to put aside overachievement in favor of socializing. You see, I come from a family of academic, high-achieving people, and they are a pretty intellectual bunch. Growing up, I thought I was stupid because I didn’t fit into that construct. It took years for me to understand that I was smart in a different way.

It’s hard to outgrow your childhood, that’s for sure. We all get slotted into roles fairly early in life: the geek, the emotional one, the sweet one. Do we ever stop being those people, deep down? I doubt it.

These roles are often assigned accidentally, but that almost makes it worse. Two kids can’t be the smartest, after all. So one of them inevitably becomes the one who is good with people, or the one who plays a better game of basketball. And unless you’re a very determined or confident person, there you stay, in that role.

I don’t have any answers. As hard as I try not to fit my own kids into roles, I can’t stop certain natural processes. I can only control what I do with dessert. You see, key lime is accustomed to being put into pie. That is key lime’s designated function. And I’ve turned it into mousse!

In case you didn’t hear about my raw egg aversion in this cappuccino mousse post, I make it a point not to make my mousse with egg. Instead, I whip heavy cream into stiff peaks, fold in my flavors, and call it a day. You could use Cool Whip, but the heavy cream tastes a little better. Or a lot, depending on your taste discernment.

This Cinco de Mayo, change up the book a little bit. Don’t be afraid to try a dessert you’ve only known in another role. And don’t be averse to embracing an identity you didn’t grow up with. We can’t stay the people we were as children, for better or worse. So let’s embrace the people we’ve become!


Key Lime White Chocolate Mousse


1 cup white chocolate chips
1 tablespoon key lime zest
2 tablespoons key lime juice
1/2 cup sugar
1 and 1/2 cups heavy cream


  1. Place the white chocolate chips in a heatproof bowl. Set aside.
  2. In a small saucepan, heat the sugar, key lime zest, and key lime juice on low until the sugar dissolves, about two to three minutes. Remove from the heat.
  3. Pour the sugar mixture over the white chocolate chips. Wait 1 minute, and then stir until the white chocolate is melted and the mixture is smooth.
  4. In the bowl of a stand mixer, whip the heavy cream until stiff peaks form. Fold the white chocolate mixture into the whipped cream until all is smoothly incorporated.
  5. Spoon the mousse into margarita glasses or bowls. Chill until set, at least one hour. Garnish with lime wedges and serve.





I fulfill many roles in life: wife, mother, teacher, everlasting learner. This site is dedicated to one role that expresses my creativity in ways that I find consistently challenging and rewarding: baker. Inventing new ways to enhance food, especially if that food involves chocolate or peanut butter (or both!), is a passion of mine. I look forward to sharing my ideas with you.

    What a great idea to make key lime mousse, Mir! I love your creativity with honoring Cinco de Mayo! I’m also loving the white chocolate in here, too. Sounds absolutely perfect!

      Thanks, Gayle! Key lime should go into a lot more than pie!

  2. Erin @ Miss Scrambled Egg

    I love this post, Mir. As the youngest child, I always was in my sister’s shadow. She did it all: captain of the volleyball team, tons of AP classes, and leadership roles in NHS and the FFA. Although I did play volleyball for two years, I gave it up to volunteer at a nature center and build bird boxes at the park. I took a few AP classes, but didn’t study as hard as some of my peers. I stayed in state to go to college. It was hard to find myself, but I think I was able to discover my voice and be true to myself. This key lime mousse speaks for itself. I want it all. This is the perfect way to celebrate Cinco de Mayo. I’ll be at a wedding that night, but I might have to make these this weekend.

      It’s a very slippery slope to imitate older siblings, because we’re all different people and need to celebrate that! As a teacher, I get frustrated when I see kids in one family all being encouraged to do the same things. It makes me mad!
      Oooh, a wedding is a fun way to celebrate, Erin! You can try this another time. πŸ˜‰

  3. Alice @ Hip Foodie Mom

    Mir, yeah, I think you are right. Who we are is kind of in our genes from the beginning. . and ha! my brother and sister were brainiacs and always did great in school. . I was always middle of the road as far as academics were concerned. . took some time for me (and my parents) to accept it but we did. And I was that shy, awkward, geeky, chubby kid in school. . As I’ve grown older and more comfortable in my skin, I’m more out-going. . it’s a process. . πŸ™‚ ok, I love what you are suggesting for Cinco de Mayo!! Change it up! LOVE this key lime mousse!!! brilliant!

      We all had awkward beginnings. Or the best of us did, right? I think having a harder time earlier helps strengthen you for adulthood. I was definitely awkward, Alice! Thanks!

    Well, this sounds just about perfect. I wouldn’t mind a vat of this mousse!

      Everything should be served in a margarita glass, Erin!

  11. Dorothy @ Crazy for Crust

    Why couldn’t you have been my honors english teacher? I was in honors for one year and I dropped out because he made me feel so stupid. I never got to experience an AP test…but hearing the name still scares me. This mousse…OMG!!

      That is such a shame, Dorothy! And you’re such a good writer, too. You would have been a great AP student. πŸ™‚ Thanks!

  12. Stacey @ Bake.Eat.Repeat.

    Yeah, I can’t use raw eggs in food either. It’s just not possible. This mousse looks amazing, love the key lime flavour!

      Oh, I hope he likes it, Kate! Let me know if you make it, and how it went!

  14. Heather - Butter & Burlap

    I personally think the moose is a great alternative than having the pie. It’s like a lighter, summertime version of the pie – delicious! Can’t wait to try it, great recipe Mir!

      Yep, no crust. I’m a fan of lighter when the weather warms up, Heather!
