If there was ever a cake that really made me think of my mom, it’s this cake. Chocolate mousse is one of her favorite desserts. Anytime I ask her for a suggestion on what to make, 9 times out of 10 she replies, “how about a healthy chocolate mousse?”.

She’s big on trying to avoid any added sugars, so the January desserts are always her favorites. As you can imagine, she was overly excited about the layer mousse cake.

Her message back to me after sharing the photos with her was simply, “LOVVVE❣️”.’

The facts

While this cake is not vegan, it is gluten-free and and free of any added sugar. I used maple to sweeten it up, and extra dark chocolate to keep the sugars as low as possible.

This is a very rich and creamy cake with notes of espresso and vanilla throughout, which we really love. It does take some time to make, but it’s mostly chill time!

And lastly, you do need a pretty high powered blender. I use my Vitamix or food processor to get the mousse nice and creamy!

Bake the crust

I wanted this to be like a fudgy chocolate cake, just a bit thinner. It’s a mix of maple, coconut oil, and almond butter, with an egg mixed in to keep the cake light.

Cocoa powder adds the chocolatey flavor, and almond flour bulks it up. Just bake and let it cool.

Make the chocolate mousse

It’s really is important to take the time to boil the cashews and let them soak. Because of this, the prep time on the cake is a little longer, but it’s by no means hard.

Once the cashews are soaked, they’ll be easier to blend into a creamy mousse. And trust me, this mousse is creamy. Because of all the nuts, it’s a little heavier than traditional mousse, but in the best way.

I added some instant espresso or coffee powder to bring out those rich, vanilla chocolate flavors.

The mousse does need time to chill, so plan ahead!

Finish it up

A simple chocolate layer on top to seal up that mousse and provide a chocolate “crack” with every bite. My one piece of advice here is to slice the cake before the chocolate top becomes too hard. This will make the cake easier to cut through.

I found that if I let the chocolate topping get too hard, it made the cake messy to cut. Since mousse can get soft at room temperature.

My moms verdict? She LOVED it, saying the espresso was possibly here favorite touch. It makes the cake just right.

Ingredients 

Crust

Mousse

Instructions 

  • 1. To soak the cashews. Place the cashews in a pot and cover with water. Bring to a boil over high heat. Boil 2 minutes, then cover and remove from the heat. Let the cashews soak for at least 30 minutes or overnight. Drain.
    2. To make the crust. Preheat the oven to 350° F. Line an 8-inch springform pan with parchment paper.
    3. In a bowl, whisk together the maple syrup, almond butter, coconut oil, egg, and vanilla. Stir in the cocoa powder, almond flour, and instant coffee. Press the mixture into the bottom of the prepared pan. Bake 10-12 minutes, until set on top.
    4. To make the mousse. Combine the soaked cashews, coconut milk, cocoa powder, maple syrup, instant coffee, vanilla, and salt in a high-powered blender or food processor. Pulse until smooth, scraping down the sides as needed, about 5 minutes. Pour the mousse over the crust. Cover and place in the fridge. Chill for at least 4 hours, or overnight.
    5. Melt together the chocolate and peanut butter in the microwave. Let cool 5 minutes and then spread the chocolate over the cake. Return to the fridge to set, about 15-10 minutes then slice. The chocolate will not be totally set, but slicing is easier this way. Keep the cake stored in the fridge.

Notes

Loose Mousse: If the mousse is too loose or messy, you can keep the cake in the freezer and remove it 10 minutes before eating to thaw.
To Make Sweeter: Taste the mouse before pouring over the crust, you can add up to 3 tablespoons additional maple syrup.

    Made this tonight! Everything turned out good except the mousse I made looks much lighter and has a much thicker layer than the picture. Perhaps I over blended.. I have a ninja and blended for the 5 minutes.

    Must be a coffee lover for this one! Base layer is delicious and fudgy ?

    1. halfbakedharvest says:

      Hey Meagan,
      Happy Sunday! I am thrilled to hear this recipe was enjoyed, thanks so much for making it! xTieghan

  2. Sarah B says:

    To make this fully vegan, do you think substituting a flax egg for a real egg will work? Can’t wait to make this!!!

    1. June says:

      I used bob’s red mill egg replacement powder and it worked great! I think the flax egg would work well too. I’m gonna try that next

      1. halfbakedharvest says:

        Hey June,
        Happy Sunday! I am thrilled to hear this recipe was enjoyed, thanks so much for making it! xTieghan

    2. halfbakedharvest says:

      Hi Sarah,
      So sorry, I have not tested this, but let me know if you give it a try! I hope you love the recipe! xTieghan

  3. Katie says:

    This looks incredible!! And thank you for a grain free dessert recipe ?. Could you sub coconut sugar for the maple syrup?

    1. halfbakedharvest says:

      Hey Katie,
      Thanks so much! Sorry, I probably would not recommend that. I hope this recipe turns out amazing for you, please let me know if you give it a try! xTieghan

  4. Cathy M says:

    I’m having a hard time correlating the 4 stars for this recipe, when I look at the comments, and no one has even made it

    1. halfbakedharvest says:

      Hi Catherine,
      Anyone who rated the recipe with stars gets averaged to the overall rating of the recipe. Whether or not they made it is out of my control. Please let me know if you have any other questions! xTieghan

  5. Shelby says:

    This is my first time making one of your dishes and I’m currently partly through mixing the cake/crust togethet- the recipe says 2 TBL of almond flour, but then the recipe instructions says to “press” the crust into the spring form pan. I’m confused because as currently written, the crust is a thick cake batter consistency- is this right or do I need to add more almond flour? Thank you!

    1. halfbakedharvest says:

      Hey Shelby,
      That is correct. Please let me know how the cake turns out, I hope you love it! xTieghan

  6. Joleen Huyck says:

    5 stars
    This looks amazing. I want to try it. I wish it truly was free of sugar. Maple syrup is sugar. Maybe I can find a substitute?

    1. halfbakedharvest says:

      Hi Joleen,
      Sorry, I haven’t tried without the maple syrup, you would really be needing to make some adjustments. Let me know if you give the recipe a try! xTieghan

  7. Barbara E Qualls says:

    How far in advance can this be made and refrigerate without loss of flavor/texture? Is 2 days too long? Can’t wait to make it!

    1. halfbakedharvest says:

      Hey Barbra,
      That should be just fine for you to do, I would probably freeze through step 4 and then finish the recipe when you want to serve. I hope you love this recipe, let me know if you try it. xTieghan

  8. Clo says:

    Hi,
    This looks fabulous and decadent. As a previous comment asked 1/2 cup maple syrup is that correct. Thank you. Happy weekend!

    1. halfbakedharvest says:

      Hey Clo,
      Fantastic! I love to hear that this recipe was a winner, thanks so much for giving it a try! Have a great weekend:) xxT

  9. Mari says:

    My daughter is allergic to cashews and almonds. What could I substitute especially for the mousse? Is there a different mousse I could use? I can figure out a crust that will work but not sure about the mousse. She can eat peanuts

    1. Ann Marie says:

      Wow! Saw this first thing this morning and I’m in. Perfect sweet for a frosty cold weekend. So interested in the crust. Only 2 tablespoons of almond flour? Can’t wait for it to come together.

      1. halfbakedharvest says:

        Hi Ann Marie,
        I hope you love this recipe, please let me know if you give it a try! xTieghan

        1. Paula says:

          Wondering if the amount of flour in the crust is correct?

          1. halfbakedharvest says:

            Hi Paula,
            Yes, that is correct. Please let me know if you give the recipe a try, I hope you love it! xTieghan

  10. Keri says:

    Looking forward to trying this for my gf/df sister! All ingredients & proportions look perfectly perfect to me.

    1. halfbakedharvest says:

      I hope you love the recipe Keri, let me know if you give it a try! xTieghan

  11. Violetta says:

    This cake looks delicious
    I was excited to make it , but noticed some of the ingredients were nut based. Due to nut allergies, are there any ingredients I can use to substitute the cashew butter, almond flour and peanut butter? I guess I’m asking for suggestions on any substitutes that would work well.
    Thanks and keep those wonderful recipes coming!

    1. Ashleigh says:

      For everyone asking for a cashew replacement, make the mousse like a normal mouse with heavy cream. The cashews are a dairy-free substitute to lighten it up!

    2. Susannah says:

      1 star
      This is really not healthy at all

  12. Shaun-Marie Jaramillo says:

    Can you substitute the cashew with another nut, I’m allergic

    1. halfbakedharvest says:

      Hey there,
      I think almonds would work well for you! Please let me know if you give the recipe a try, I hope it turns out amazing for you! xTieghan

  13. Kristiana says:

    Holy mother. This immediately was filed under splurge worthy desserts. It’s 6am and I’m salivating! Can’t wait to make soon.

    1. halfbakedharvest says:

      Hey Kristiana,
      Lol thank you so very much! I hope you love the recipe!! xTieghan

  14. Kate says:

    Maple syrup (not maple!) is added sugar just an fyi!

    1. Brenna says:

      Thank you for saying this. I was thinking both of these things. Maple syrup is refined sugar, made by refining maple sap. And “maple” can describe lots of other things… maple sugar, maple butter, maple candy… any gift shop in Vermont will demonstrate that. 🙂

      That said, this dessert looks delicious and I plan on making it asap with a different (vegan) chocolate cake layer, soy or cashew milk instead of coconut milk (no/less saturated fat), and date syrup instead of maple syrup (still refined, but uses the whole date, so you get the fiber, vitamins, minerals, etc.).

      1. Deanna says:

        I wouldn’t exactly call maple syrup refined- it is simply maple sap with most of the water boiled out of it to concentrate the sweetness. Maple syrup also contains minerals.

    2. Cindy says:

      Want to give this a try but I don’t have a “high power” food processor so will that be a problem?

      1. halfbakedharvest says:

        Hi Cindy,
        It depends what you have? Do you have a regular food processor? That should work! Let me know! xTieghan

    3. halfbakedharvest says:

      Thanks so much Kate!

  15. SEG says:

    Is it really 1/2 c maple syrup in the crust? That seems like a lot in proportion to the other ingredients.

    1. SEG says:

      I am asking because I would love to make it but do not want to waste any maple syrup!

      1. halfbakedharvest says:

        Yes, that is the correct measurements, no maple wasted:)

        1. SEG says:

          Thanks! I’ll give it a try soon!

          1. halfbakedharvest says:

            Awesome!

      2. ToniAnn says:

        Can’t wait to try this! You mentioned not to let the chocolate get too hard before slicing, can you recommend an approximate amount of time that would be best? Trying to time everything right. Thanks!

        1. halfbakedharvest says:

          Hi ToniAnn,
          It really depends on the type of chocolate you are using, but typically 10-15 minutes. I hope you love this recipe, please let me know if you give it a try! xTieghan

    2. halfbakedharvest says:

      Hi Suzi,
      Yes, that is correct. Please let me know if you have any further questions and if you give the recipe a try! xTieghan
