Raspberry Mousse (Cake Filling and Dessert)

This post may contain affiliate links. Please read our disclosure policy. As an Amazon Associate, I earn from qualifying purchases.

Thick and creamy with the sweet, fruity flavor of raspberries, our raspberry mousse recipe makes a delicious cake filling and a standalone dessert.

The recipe begins with a sauce made from fresh raspberries that will leave you with plenty of extra for drizzling onto the mousse or serving alongside another dessert, like this lemon raspberry parfait or our flourless chocolate cake. This is one for your recipe box.

Fresh or Frozen Raspberries

When it comes to making this fluffy, whipped dessert, you have the flexibility to choose between fresh or frozen raspberries. Both options work marvelously in this easy recipe.

Fresh raspberries are ideal when the berries are in season. On the other hand, frozen raspberries are a convenient choice that allows you to whip up this luscious dessert year-round.

Either way, you’re on track to creating an easy, gluten free, dessert that will delight everyone.

Raspberry Cream Mousse

We love serving this mousse in individual dessert cups, but many of our mousse recipes also make great cake fillings!

This raspberry mousse sets up firmly and is similar to our white chocolate mousse filling in that it’s perfect to pipe or spread between two fluffy cake layers.

The sweet, fruity flavor of raspberries pairs beautifully with a variety of cake recipes, from a white chocolate cake to our coconut cake and this 6-inch yellow cake recipe. It even goes well with our perfect chocolate cake.

And while we also have a raspberry white chocolate mousse recipe, this recipe uses more raspberries and you can drizzle it with extra puree or even some ganache. 

Why this Raspberry Mousse Recipe Works

The mixture of mascarpone, heavy cream, and raspberries gives this dreamy raspberry mousse a rich and creamy consistency that remains light and fluffy.

Our raspberry mousse is:

  • Delightfully fruity with a perfect balance of sweetness and just a hint of tartness from the raspberries.
  • Quick and effortless to prepare.
  • Super versatile and great for enjoying on its own or as a filling in a cake!
  • This dessert is perfect for enjoying all year round, and you even have the option to use frozen raspberries.

How to Make Raspberry Mousse

We start by making a puree with the raspberries. You will not use all of the puree in the mousse but don’t toss it out because it is great drizzled on top or used in other recipes.

If you plan to serve this easy raspberry mousse as dessert, just pour that leftover sauce on top. It creates a beautiful red swirl and gives it an extra punch of fresh flavor.

If you’re making the mousse for a cake filling, save the extra sauce for strawberry ice cream, sourdough pancakes, crispy yeast waffles, or lemon ricotta cake.

Here’s a look at how to make raspberry mousse (scroll down to the bottom of the page for the printable recipe card and all of the details):

  1. Make the sauce: Cook the raspberries with the sugar and pour it through a strainer then discard the pulp and seeds.
  2. Bloom the gelatin: Before dissolving and liquefying the gelatine, it is important to allow it to bloom (or hydrate.)
  3. Beat the cream: Use a chilled mixing bowl to mix the mascarpone cream with the sugar. Don’t over beat the mascarpone. Add the cream and whip to stiff peaks. Pour in the fresh raspberry sauce and fold it with a wide spatula.
  4. Serve the raspberry mousse: Divide it into individual dishes (we like to pipe it into glasses) or use it as a cake filling. If you plan to serve it as a dessert, drizzle the extra sauce on top and garnish with fresh raspberries.

This is perfect for brunch recipes or a Mother’s Day dessert. It is easy to make and only requires a few simple ingredients. It’s one of those recipes that looks impressive but doesn’t take a lot of time.

Recipe Tips for Success

  • Chill the cream and mascarpone. You will also get better results if you chill your mixing bowl. Just pop it in the fridge while you make the sauce.
  • Do not over whip the mascarpone. If you whip it to much, it will break and curdle. This is actually the trickiest part because the mascarpone is so easy to over beat.
  • Let the gelatin hydrate or bloom before you heat it to dissolve the granules.
  • Do not get the gelatin too hot. Blast the gelatin in the microwave in 3-second increments just until it is liquid. If gelatin gets too hot, it will not set up properly.
  • Serve in pretty glasses: wine glasses or champagne glasses make a beautiful presentation!
  • Let it chill: It will get thicker after it chills in the fridge.

Frequently Asked Questions

How long does fruit mousse last in the fridge?

Our raspberry mousse will last up to five days in the fridge. It will get thick and firm when it chills for at least 4-6 hours.

What is the difference between pudding and mousse?

A big difference between mousse and pudding is that pudding gets cooked and it is often thickened with corn starch.

Mousse does not usually need to be cooked. Whipped cream or whipped egg whites give it a fluffy, lighter consistency than pudding.

Raspberry Mousse

Yield: 8 servings (4 cups)
Prep Time: 20 minutes
Cook Time: 12 minutes
Total Time: 32 minutes

Thick, creamy raspberry mousse makes a beautiful dessert piped in glasses or uses the mousse for a cake filling. Since the mousse sets up firmly, you can put a thick layer between cakes.

When you make the raspberry sauce, you will end up with 1-1/4 cups to 1-1/3 cups of sauce. You will only use 1 cup of sauce to make the mousse and you can use the remaining sauce to drizzle over the top of the mousse when you serve it.

Ingredients

Make the Raspberry Sauce

  • 24 ounces fresh or frozen raspberries
  • 1/4 cup sugar
  • 1 tablespoon lemon juice

For the Raspberry Mousse

  • 2-1/2 teaspoons unflavored powdered gelatin
  • 1/4 cup water
  • 3/4 cup (6 ounces) mascarpone cheese, chilled
  • 1/2 cup sugar
  • 1 cup heavy cream, chilled

Instructions

  1. Place a mixing bowl and whisk in the fridge to chill while you make the raspberry sauce. You will use the chilled bowl when you whip the mascarpone and cream.
  2. Place the raspberries, sugar and lemon juice in a saucepan. Cook over medium heat, breaking it up with a fork or potato masher. Cook, stirring frequently for 10 to 12 minutes. 
  3. Place a strainer over a bowl and pour the raspberry mixture into the strainer. Push the mixture through the strainer to get as much juice and pulp into the bowl as possible. You should have 1-1/4 cups to 1-1/3 cups of sauce in the bowl. Toss out the seeds. 
  4. Measure out 1 cup of the raspberry sauce and place it in a bowl. Save the remaining puree to drizzle over the top of your mousse when you serve it. 
  5. Place 1/4 cup of water in a small microwavable bowl. Sprinkle the gelatin over the top of the water and let it sit for 3 to 5 minutes. 
  6. Place the bowl in the microwave for 6 to 12 seconds stopping to stir every 3 seconds until it gets liquified. Do not cook the gelatin mixture too much as high heat will destroy the thickening power of the gelatin. 
  7. Stir the gelatin mixture into the bowl with raspberry puree. 
  8. Add the mascarpone cream and the sugar to a chilled bowl and beat on low speed just until the sugar gets incorporated, about 30 seconds. 
  9. Pour in half of the heavy cream, beat for 30 seconds to 1 minute until the mixture looks liquid. Stop the mixer and scrape down the sides of the bowl.
  10. Pour in the rest of the cream and beat on medium-low speed until the mixture reaches soft peaks. 
  11. Pour in the raspberry/gelatin mixture and beat on medium-low speed until stiff peaks form. If it reaches stiff peaks before the raspberry is fully incorporated, stop whipping and use a wide spatula to fold the mixture until the raspberry is completely combined.
  12. Divide among six to eight dessert glasses or use as a cake filling. Use any remaining raspberry puree to drizzle on top of the mousse. 
  13. Keep chilled until time to serve. The mousse will thicken even more after 4 to 6 hours in the fridge. 

Notes

  • Make sure the cream and mascarpone are chilled as well as the bowl.
  • Don't whip the mixture too long or the mascarpone will break and look curdled. As soon as you see the mixture reach stiff peaks, stop the mixer. If the raspberry puree is not fully incorporated by that time, you can use a spatula to gently fold the mixture.

I love this raspberry mousse! I made a chocolate chiffon cake for my husbands bday and split it into three layers and filled with this mousse. I did forget to pick up mascarpone cheese so I used philidelphia cream cheese instead and it came out perfectly. Everyone who tried it thought it was fantastic and this includes some fairly picky eaters! I am wondering if I could use this base for other flavours. Strawberry, chocolate, cherry? I hate those mousses that use raw egg and will not take that chance so I hope to make these flavours as well. Any changes I might need to make here?

Certainly! You can definitely use this recipe as a base for a variety of flavors. When switching to different fruits, keep in mind that the water content can vary significantly, which means you might need to adjust how long you reduce the fruit puree. For a chocolate version, melt some chocolate and fold it into the mousse base. Your successful substitution of cream cheese for mascarpone will continue to work well with these flavor variations.
