This healthy Key Lime Pie Mousse Recipe is light and fluffy, just the way a dessert should be!

Except unlike most desserts, this one is extra healthy and full of healing properties and nutritional benefits.

Healthy Key Lime Pie Mousse Ingredients


This dessert reminds me of key lime pie, hence the name, but I just used regular limes here because key limes can be a little hard to come by. Key limes and what most people know as regular limes (technically called Persian limes) are really similar. Key limes are sweeter, so I simply added honey to this dish to balance out the tanginess of the lime and mask the flavor of the avocado. Use fresh lime juice just squeezed from the limes, none of that bottled stuff.

Soaked Cashews

Soaked cashews add a wonderful creaminess to raw vegan dishes. If you have a cashew allergy, you can replace these with the flesh of one more avocado.


Avocados pretty much do it all. They work in savory dishes, sweet dishes and are even great plain with a little bit of sea salt. Avocados are a fantastic source of healthy fats, vitamins, minerals, and antioxidants. They’re a no-brainer and make desserts much healthier, plus the honey and lime mask the flavor so you can’t even taste it here.

Raw Honey*

Raw honey is full of natural enzymes, vitamins, and minerals—it’s one of the most nutritious foods on the planet. I prefer raw honey in this dish as the floral notes of the honey complement the lime and texture of the dish.

*Honey isn’t technically vegan but some people who choose the vegan lifestyle still consume it for its healing properties. Hard-core vegans may still avoid honey as it comes from bees. If that’s the case for you, use 100% real maple syrup or your vegan sweetener of choice to make this dish completely vegan.

Fresh Ginger

Fresh ginger has strong antimicrobial and anti-inflammatory benefits. Plus, it’s delicious! It really makes this dish pop and I recommend it, but feel free to leave it out if you know you don’t love it.

Sea Salt

Always add a pinch of sea salt, especially in desserts. From a culinary perspective, a pinch of salt makes sweet things taste sweeter. From a nutrition perspective, sea salt adds trace minerals to your food without the anti-caking agents and preservatives found in regular table salt.

I love this decadent dessert after dinner, but it’s healthy enough to eat for breakfast, too.

  • Author: Elizabeth Rider
  • Prep Time: 5 mins
  • Cook Time: 10 mins
  • Total Time: 15 mins
  • Yield: 8 1x


Units Scale
  • 1/3 cup lime juice (from freshly squeezed limes)
  • 1 cup unsalted, unroasted (raw*) cashews, soaked overnight or quick-soaked
  • 2 large avocados (or 3 small), pitted and flesh scooped out
  • 1/4 cup raw honey**, or real maple syrup
  • 1/2 cup filtered water (more or less to blend smooth)
  • 1/4 teaspoon sea salt
  • 1/41/2 teaspoon freshly grated ginger (optional, but recommended)
  • 1 teaspoon lime zest, for garnish


  1. Zest the lime and set aside for garnish.
  2. Blend the rest of the ingredients in a high-speed blender, such as a Vitamix, until smooth. I find a high-speed blender to be the best tool to get this mousse smooth.
  3. Spoon into ramekins or serving dishes (I used mini martini glasses here) and top with a pinch of lime zest for garnish.
  4. Serve immediately or refrigerate. Will keep in the refrigerator up to 24 hours and freezes well.
  5. Serving size: about 1/4 to 1/3 cup.


How to soak cashews: You can choose to soak your cashew nuts overnight; otherwise you can do a quick soak, where you use hot water and soak for 1 hour.

*Technically cashews are never raw because they’re steamed to remove a toxic coating before packing. In this instance, raw means not roasted and not salted.

**I prefer raw honey in this dish as the floral notes of the honey complement the lime and texture of the dish. Use 100% real maple syrup to make this dish completely vegan if desired.
