Creamy Blackberry Mousse

We have mango mousse, cherry mousse, peach mousse, and even cranberry mousse.  And now this blackberry dairy free mousse joins the cool club!  

Likely when you hear the word mousse, you immediately go to a chocolate mousse.  But chocolate shouldn’t have all the fun when it comes to one of the easiest and most delightful desserts.  Fruit is transformed into a dreamy dessert anytime you combine it with whipped cream!

Why You’ll Want To Make This Velvety Dessert

  • Only 6 ingredients! – And that includes the water!
  • Super creamy – The whipped coconut cream makes the mousse luxuriously smooth and velvety.
  • Bright fruit flavor – Blackberries are definitely the star in this creamy fruit dessert, since they are the only key ingredient!
  • No-bake summer dessert – I’m all for a dessert that doesn’t require me to turn on the oven on a 90 degree day!
  • Portable – The mousse is simply sweet in flavor and style!  I’m a fan of carrying around too cute desserts – just like my strawberry smore’s parfait.

Everything You Need To Make Blackberry Mousse


  • Blackberries – I recommend fresh blackberries, especially when in season.  You can use frozen if you prefer.
  • Lemon Juice – The lemon juice brings out the brightness of the fruit.
  • Honey – I like to pair honey with fresh blackberries because of its floral and fruity notes.  You can use any sweetener you prefer.
  • Water – The water is to bloom the gelatin.
  • Gelatin – Use unflavored powdered gelatin.  
  • Unsweetened Coconut Milk – A can of unsweetened coconut milk does double duty in the mousse – to thicken it and as a topping.  Canned coconut cream will also work.  

Kitchen Equipment

  • Blender – A good blender is a great kitchen investment!
  • Mixing Bowls – This includes a small prep bowl for the gelatin.
  • Strainer – A fine mesh strainer to get the seeds out of the fruit puree.
  • Serving Glasses – Or serving bowls – whichever serving dish you prefer!

Tips For Super Creamy Blackberry Mousse

  • Strain the fruit – Especially with a fruit like blackberries, you will want to take the extra step to get all of the seed out.  Unless you’re a fan of chewing on the crunchy seeds!
  • Use coconut milk – Dairy milk will certainly work.  However, I find when a can of coconut milk is whipped into a cream, it is much more thick and creamy.  Which is probably why I use it so much when I want whipped cream!
  • Give it time to chill – We want to give the gelatin time to help the mousse set, and that will take some time.  Just think of how long you had to wait to eat the Jell-O your Mom made when you were a kid! 
  • Top with extra whipped cream – For a little extra cream, but the whipped cream also makes for a pretty dessert.

Is Dairy Free Mousse Just As Creamy

It certainly is!  In fact, I will go as far to say it is creamier. 

Now, I love traditional whipped cream.  I even love to put it on my fudgy brownies.  But I do find dairy whipped cream deflates much faster than whipped coconut cream. 

I’m sure it has something to do with the fat content, and the fact that we are whipping straight coconut solids.  But what is even better (in my opinion!) is that whipped coconut cream will actually get firmer when it is chilled in the refrigerator.  Which makes eating spoonful’s of it delicious or making your overnight oats ridiculously creamy!

FAQ’S: How to Make Dairy Free blackberry Mousse

Can this recipe be doubled?

It certainly can!

It’s not blackberry season. Can I use frozen fruit instead?

Yes, you can. You may want to defrost the frozen berries slightly so they are easier to strain. Otherwise, follow the instructions as written.

Will flavored gelatin powder work?

While it may work, the flavor will likely overpower the fruit.

Can I swap in a different sweetener?

You can. I would taste test as you go to get your desired sweetness.

Can I make the mousse vegan?

You can swap the honey for a different sweetener. And while I don’t have experience with it, you can try using agar agar instead of the gelatin. Follow the instructions on the package to substitute.

Do I really have to let the mousse chill for 4 hours?

I recommend it if you want a creamy mousse. The gelatin needs time to firm up. Otherwise, while still delicious, it may eat more like a yogurt than mousse.

Blackberry Mousse

Yield: 2 Servings
Creamy, dairy free blackberry mousse is your answer to a beautiful summer dessert without all the effort!  With only 6 ingredients needed – and that includes water! – the fruit mousse is incredibly easy to make, with no baking required.  The mousse is bright, velvety, and a certain showstopper at your next summer event!
Prep20 minutes
Chill4 hours
Total4 hours 20 minutes




  • In a blender, add the blackberries, lemon juice, and honey. Puree until light and smooth. Keep in the blender and set aside. Optional – Reserve some blackberries as a topping.
    8 ounces fresh blackberries, 1 teaspoon lemon juice, 3 tablespoons honey
  • In a small prep bowl, add the water. Sprinkle the gelatin over the top, let sit for 5 minutes to allow the gelatin to bloom – it will resemble a firm gel when ready. Then, heat the bloomed gelatin to a liquid in the microwave – only about 5 to 10 seconds.
    1 ½ tablespoons water, 1 teaspoon unflavored gelatin powder
  • Pour the liquified gelatin into the blackberry puree in the blender and mix for another 30 to 45 seconds – until all ingredients are thoroughly blended.
  • Strain the blackberry puree through a fine mesh strainer set over a bowl – to remove the seeds. Cover the bowl and chill in the refrigerator until is starts to thicken. About 1 hour. 
  • While the blackberry puree is chilling, make whipped cream with the coconut milk. Add the coconut cream solids to a medium mixing bowl. Using a hand held mixer, beat until soft peaks form. Set aside in the refrigerator until ready to use. Note – Sweetening the whipped coconut cream is optional. If you prefer a sweeter dessert, add a tablespoon of honey to the whipped cream as you are whipping it.
    13.5 ounces unsweetened canned coconut milk, full fat
  • Once the blackberry puree has thickened, add 3/4 cup of the whipped coconut cream. Gently fold the mix together until no streaks remain. The mousse will be the consistency of the whipped cream and will continue to firm as it chills. Set aside any remaining whipped cream in the refrigerator, to use as a topping.
  • Equally portion the mousse into the serving glasses. Cover and chill for at least 3 hours to allow the mousse to set. When ready to serve, top the mousse with the reserved whipped cream and blackberries. Enjoy!

  • Serving Size – This is intended to be a recipe for two people.  For a larger batch, the recipe can easily be doubled.
  • Whipped Cream – I prefer whipped coconut cream for a creamier whipped cream.  However, you can swap in dairy whipped cream.
  • Sweetener – Swap in any sweetener of choice.  Taste test as you go and add more sweetener to get desired sweetness.  Keep in mind, the fruit is inherently sweet and too much sugar will overpower the fresh fruit flavor.
  • Chill Time – Refrigerate for at least 4 hours total to give the mousse time to set.  Overnight is also a great option.
  • Strain the Puree – I recommend straining the fruit puree to remove the seeds and for a super smooth mousse.
