Sometimes, we all desire a sweet, maple-y dessert in autumn, which brings us to maple mousse. Smooth, rich, sweet. (It's even better with a caramelized walnut on top.) It might sound hard to make, but actually, it's quite simple!
Looking for more mouthwatering fall desserts? We love this maple walnut bundt cake and these pumpkin pie bars.
Ingredients
Curious what ingredients you need to whip up this easy fall dessert? Grab these key ingredients, and you'll be ready to make this tasty maple mousse!
- Maple Syrup: This is by far the most important ingredient! Be sure to choose a high quality, real maple syrup for the best flavor. (If you're like me, use one from Canada! 🍁)
- Gelatin: This is what helps the mousse set. Either gelatin sheets or powdered unflavored gelatin will work here.
- Heavy Cream: You'll whip this up to make homemade whipped cream. This makes the mousse light and creamy.
- Egg Yolks: This thickens the maple syrup and adds richness to the mousse.

How to Make Maple Mousse
Measure out the ingredients: maple syrup, gelatin powder, water, egg yolks, and heavy whipping cream.
- Stir together the gelatin and water and let it stand for 5 minutes so the gelatin can "bloom." (image 1)
- Pour the maple syrup into a small saucepan and let it warm up over medium heat. Whisk the gelatin mixture until dissolved, then bring the syrup to a gentle simmer. (image 2)
- Slowly pour the hot syrup into the egg yolks, whisking quickly. (image 3)
- Dump the mixture back into the pan and whisk over medium heat until the mixture reaches 160°F. Pour the syrup into a bowl, then place in an ice bath for about 10 minutes, or until it has cooled to room temperature and has thickened considerably. (image 4)
- While the syrup is cooling, whip the heavy cream until stiff peaks form. The cream shouldn't fall out of the bowl if you turn it upside down! (image 5)
- Dump the syrup into a large bowl and stir in two large spoonfuls of whipped cream. Don't worry if there are a few lumps at this stage. (image 6)
- Gently fold in the rest of the whipped cream. Keep folding until no white streaks or lumps remain--it will take a minute or two! (image 7)
- Divide the mousse among glasses or bowls, cover with plastic wrap, and chill for at least 2 hours before serving. Decorate the mousses with caramelized walnuts if desired and serve cold. (image 8)
Recipe FAQs
To make a mousse, you need two parts: a base (which provides the flavoring) and an aerator (which makes the mousse light and fluffy). The base can be anything from melted chocolate to puréed fruit, while the aerators are usually whipped cream, meringue, or eggs. In this recipe, we're using maple syrup as our base, and whipped cream as the aerator. Read more about bases and aerators if you're curious.
Many mousses take about 15-30 minutes to set. Chocolate mousse sets more quickly because chocolate naturally hardens in the fridge. Since this mousse doesn't contain chocolate, it takes about 2 hours to set.
Make Ahead: You can make this up to 24 hours in advance and keep it in the refrigerator until needed. I wouldn't let it sit longer than that, as it may start to get watery from the whipped cream.

Expert Tips
- When you pour the hot maple syrup mixture into the egg yolks, make sure to go slowly and whisk the yolks briskly to prevent them from curdling.
- If you do happen to get a few lumps of egg, just pour the liquid through a sieve to remove them.
- Make sure the whipping cream is cold. Warm or room-temperature cream won't get as much volume when it's whipped.
- Fold the whipped cream into the maple syrup mixture gently. Avoid stirring it to keep the mousse airy and light.
- Be sure to allow sufficient time for the mousse to set--no less than 2 hours.

How to Make Maple Mousse
Ingredients
- 2 ½ teaspoons unflavored gelatin powder, 1 envelope
- ¼ cup cold water
- ¾ cup maple syrup
- 3 large egg yolks
- 2 cups heavy whipping cream
Instructions
- Stir the cold water into the gelatin until dissolved, then let stand for 5 minutes. The gelatin will absorb the water and begin to set (called "blooming").
- Pour the maple syrup into a small saucepan over medium heat. Let the syrup warm up for a minute, then whisk in 1 tablespoon of the gelatine until dissolved. For an extra firm mousse, use all of the gelatine.
- Bring the syrup to a gentle simmer, then very slowly pour it into the egg yolks, whisking them continuously as you pour. Dump the mixture back into the pan and cook over medium heat until the mixture reaches 160 F on a candy thermometer.
- Pour the maple syrup mixture through a sieve into a small bowl to remove any lumps. Set it inside an ice bath for 10 minutes, stirring occasionally, until the liquid has thickened to a syrupy consistency and has cooled to room temperature.
- Meanwhile, beat the whipping cream until stiff peaks form. The cream should be thick enough not to fall out of the bowl when it's turned upside down.
- Pour the maple syrup mixture into a large bowl, then stir two large spoonfuls of whipped cream into it. Add the rest of the whipped cream and gently fold it in with a silicone spatula until no lumps or white streaks remain.
- Pour the mousse into glasses or bowls and chill in the fridge for at least 2 hours. Garnish with caramelized walnuts and serve immediately.

Notes
- Temper the mixture slowly. Pour the hot maple syrup mixture slowly onto the eggs, whisking constantly. Going too fast might scramble the eggs.
- Got lumps of egg? Pour the mixture through a mesh sieve to remove them.
- Use cold whipping cream. Room-temperature cream will not whip as high as cold.
- Fold gently and avoid stirring to keep the mousse light and airy.
- Let the mousse set for at least 2 hours, or it will not be very firm.

Question on steps 3-4: once you pour syrup over eggs and temper- how long do you whisk/temper eggs before returning mix back to stove ? How do you know when to put back on stove ? If the mousse is being used to fill a cake do you recommend using all the bloomed gelatin? And is gelatin powder or sheets better for a sturdier mousse ? I have never used either so any tips appreciated ! Thank you !
Emma Fajcz
- You can pour the tempered mixture back into the pot and heat through as soon as the syrup is mixed into the eggs.
- I wouldn't use more than 2 to 2 1/2 tablespoons of the set gelatin, even if you're filling a cake with it, or the mousse may be too rubbery. I haven't tested the mousse in a cake so I can't guarantee the amount is right.
- Either gelatin powder or sheets work well--they're just different forms of the same thing. I use the powder because I can't get sheets in my area.
Hope this helps, Jenna! Happy baking.

Hi,
I would like to use your maple mousse recipe to fill a cake. I mean, like, a hole in the middle of a cake that was undercooked, so I scooped out the middle. The cake layers are currently frozen. Would you suggest filling and sticking back in the freezer, allowing to set, then filling, mixing set/unset mousse with cake crumbs, then allow to set in the fridge/freezer, other?
Thanks for your help!
p.s. Sorry I did not leave any stars... I haven't tried making the recipe, yet!
Emma
Yes, you can try that if you'd like. I wouldn't mix cake crumbs in the mousse; it would create an unusual texture. Let it set in the fridge for a couple of hours. Let me know how it goes!

This looks very elegant. The shard of caramelized walnut on top is nice. The maple flavor is not too strong.🍁🍁
Emma
It was fun making those caramelized walnuts! I'm glad that you liked the mousse, too. 🍁
