Raspberry and Vanilla Bean Mousse Cake

Do you ever think of an idea for a dish, maybe one that's a little more complex than your usual so you're kind of worried about messing it up big time, but then you totally pull it off and it's exactly what you imagined?!

I did that.

Not to toot my own horn too much, but this cake is my newfound pride and joy. I came up with the idea of a raspberry and vanilla mousse cake a few weeks ago, but it was just a vague idea. Over the course of a week, I finalized what I wanted the components to be and how I wanted to decorate it. I searched my many many books for recipes that I wanted, tweaked some to fit my needs, and just went for it!

First try was a total fail. The gelée didn't have enough gelatine in it so it was too liquidy when it thawed, which meant that the whole structure of the mousse cake was off. You cut into it and then bleeeuuurrrghh - out comes the gelée kind of like blood, which was creepy. And then it's all over the plate and you're just left with diplomat cream that had too much gelatine and the whole thing is just not working.

So, I rethought the recipes and tweaked them over the course of the next week, and tried again the next weekend. If this didn't turn out, I was probably going to abandon the idea because I get kinda spiteful when it comes to failed desserts.

But then it turned out perfectly! Like, exactly perfectly! Perfect texture, perfect taste, perfect contrast, perfect look! I can't remember a time when I nailed it this good

This might just be my ideal mousse cake. I love mousse and custards (I think most of the posts on this blog contain mousse and/or custard), so to say this is my favourite is big. The sweet creaminess of the light vanilla diplomat cream is the perfect foil for the tart and flavourful gelée (that is not like jell-o, I promise). A bit of crunch from the sablé and then another hit of raspberry from the spongey but intensely raspberry-y cake.

I want everyone to make this cake. Heck, I want to make this cake again just so I can eat it again. I want someone to have a party so I can make this cake in a big version, but everyone else is health conscious so I eat the majority of it. I want to stare at these photos all day and bask in the feeling of "Man, I nailed that". I want to carry photos of this cake in my wallet and when people proudly show me photos of their kids, I can pull out my photos and say, "Yeah, but look what I made." 

Too much? Naaah.

Diplomat Cream

300 g pastry cream

5 g gelatin sheets

Crisp Meringue
Recipe adapted from Frozen Desserts

75 g egg whites
75 g granulated sugar

To finish

White cocoa butter spray
Neutral cold glaze

First, line four 3-inch rings with acetate and place on a silpat lined baking sheet. 

To start, make the raspberry cake. Place a silpat on a half sheet pan and spray the border with non-stick oil spray. Preheat the oven to 320 F.

Sift the flour, baking powder, and vanilla powder in a bowl. Set aside.

Cream the butter in the bowl of a stand mixer until pale and creamy. Scrape down the bowl and add the sugar, beating until combined. Then add the eggs, beating until combined. Slowly add the raspberry purée, scraping down the bowl halfway through.

Fold in the dry ingredients. Pour the batter into the sheet pan and use an offset spatula to spread the batter in an even layer.

Bake for 12 to 15 minutes, until the cake springs back in the middle when you apply gentle pressure with your fingertips. Remove the cake from the oven and cool to room temperature.

Cut out 3 inch circles from the raspberry cake and place them inside the rings.

For the raspberry gelée, place four 2.75 inch rings on a silpat lined baking sheet. 

Combine the raspberry purée and icing sugar in a saucepan and heat over medium heat. Bloom the gelatine sheets in ice water to soften.

Once the gelée is hot but not boiling, remove from the heat. Squeeze the excess water from the gelatine and add to the purée, whisking to dissolve. Pour 50 g of gelée into each ring. Place in the freezer and freeze until solid, about 4 hours.

Once completely frozen, remove from the rings and reserve in the freezer.

For the sablé, sift the all-purpose and cake flour together.

Cream the butter, salt, icing sugar, and almond flour together on medium speed in an electric mixer bowl fitted with the paddle attachment. Scrape the seeds from the vanilla bean and add to the mix. Mix until a homogenous mass is obtained, about 2 minutes.

Stop the mixer, add the eggs and mix for a few seconds on low speed until the eggs are completely incorporated.

Stop the mixer, add the sifted flours, and mix for a few seconds, pulsing the mixer at first to keep the flour in the bowl. Mix just to obtain a homogenous mixture. 

Shape the dough into a flat square and wrap with plastic wrap. Chill for 1 hour.

Preheat the oven 325 F.

Roll the dough out to a rectangle 3mm thick, then chill again until slightly firm, 10 to 15 minutes. Cut out four 3-inch circles and place on a baking sheet lined with a silpat or parchment paper and refrigerate until firm, about 30 minutes. Wrap the leftover dough tightly in plastic wrap and freeze to use at another time.

Bake the sable for 12 to 15 minutes, until there is only a slight bit of golden brown on the underside of the sablé. Remove from the oven and let cool completely.

Place the sablé on top of the raspberry cake in the rings.

For the pastry cream, combine the egg yolks, sugar, and cornstarch in a medium bowl. Whisk until slightly paler in colour.

Scrape the seeds from the vanilla bean and add to a medium saucepan along with the milk.

When the milk mixture has come to a boil, slowly pour a small amount into the yolk mixture, whisking continuously. Continue tempering the yolks with the milk mixture, then transfer all of back into the saucepan. Cook over medium-low heat, whisking continuously, until the mixture has thickened, about 4 minutes. Continue to cook for another minute, then strain through a fine-mesh sieve into a clean bowl. Whisk in the butter.

Set the pastry cream over an ice bath to cool. Once it has reached room temperature, place a piece of plastic wrap directly on the surface to prevent a skin from forming and refrigerate for 2 hours.

For the crisp meringue, preheat the oven to 200 F. 

Place the egg whites in the bowl of a stand mixer and whip on medium-high speed until the egg whites are frothy. Slowly stream in the granulated sugar and whip to stiff peaks. Fold in the icing sugar.

Spread the meringue on a silpat in a thin even layer using an offset spatula. Bake the meringue until crisp, about 1 hour. Do not let the meringue bake too long or it will colour and no longer be white.

Remove from the oven and cool completely, then break into irregular shards. 

For the diplomat cream, bloom the gelatine in ice water to soften. Place a 50 g of the pastry cream in a bowl set over a bowl of simmering water and stir often. Once it has reached 60 C, squeeze the excess water from the gelatine and add to the pastry cream, whisking to dissolve. Remove from the water bath and quickly fold into the remaining pastry cream.

Fold one-third of the whipped cream into the pastry cream. Fold in the remaining two-thirds and transfer to a piping bag. 

Pipe the molds halfway up with diplomat cream. Place the frozen raspberry gelée disk on top, pressing gently in so the surface of the gelée is flush with the diplomat cream. Pipe diplomat cream to fill the ring, then smooth the top with an offset spatula. 

Place in the freezer and freeze for at least 6 hours, or preferably overnight.

Remove the rings and the acetate. Spray an even layer of white cocoa butter spray onto the cakes and freeze for 10 minutes to set. Reserve in the fridge to thaw.

When ready to serve, decorate with shards of crisp meringue. Halve a raspberry and brush the inside with neutral cold glaze and arrange on the cake, along with a whole raspberry.

    1. Thanks! I love making individual desserts, they're so much cuter and more special than one big one!

  2. where did you get the cocoa butter spray? i try to find it but the shipping cost is so high.

    1. I work in a patisserie so I was able to order it through one of our suppliers! Sorry it isn't much help! The cake will still look nice without the cocoa butter spray.

    2. Is that how you get the texturing on the outside of the cake? The spongy look.

  3. This is beautiful and just the sort of beautiful entremets that I love to read about and attempt to create myself. A stunning dessert, I love it!

    1. Thank you! I've been drawn more towards making entremets now that I work in a patisserie. Seeing all the amazing desserts that we have at work inspires me so much!

  4. Good for you for sticking with it- congrats! This is too pretty to eat. Your photos (as always) are amazing! Well done!

    1. Thank you so much! I sometimes have a tough time with trying a dessert after I've failed at it. I get super spiteful and angry and I just give up. But I knew this could be a good one if I got it right, so I kept at it!

  5. beautiful and so creative!

  6. "You cut into it and then bleeeuuurrrghh - out comes the gelée kind of like blood, which was creepy"

    hahahhaha. this was awesome. I can imagine the gelee bllleeuurgghhh-ing out of the cake.

    oh and the end result looks beautiful :)

    1. Haha thank you, I'm glad you understand what I mean! I use sounds waaay too often to describe actions, even in my writing! But sometimes sounds explain things so much better.

  7. Wow, this is just amazing. Your photos are great, and the instructions are so easy to follow! I will definitely try to make this one!!! Your blog is a great place for inspiration!

  8. Hi! Really lovely! Do you have a recommendation for the baking rings? I'm just a home baker, and wasn't sure where to get rings that are high enough but also different diameters (on amazon.co.uk there are sets that sell rings of different diameters but then the height seems rather low or are called cake rings. The ones that look higher are called cooking rings (sometimes) but come in sets of uniform diameter. And is the acetate necessary to use with these rings, or can I sacrifice perfect appearance by just using the rings without? Thanks! Really excited to try out your recipes - stumbled across your blog by way of the smores individual cakes :)

    1. No problem! It can be confusing for someone who has never seen the exact kind of pastry ring used for built cakes, especially since most baking stores won't have them!

      I use an awesome pastry supply store for most of my baking equipment now, it's called www.dr.ca. They have tons of different sizes and diameters of pastry rings, it all depends on what size you want. The ones I've used for this cake are 3 inches wide and 1.75 inches high, but you can get almost any size you want. http://www.dr.ca/mousses-and-entremets-ring-moulds-5-75-and-less.html is the link to the rings I bought, just use the drop-down menu to select the sizes you want.

      Acetate is pretty necessary because without it, I don't know how cleanly (or if at all) your cakes will come out of the rings. The acetate is there so the rings can just slide right off and then when you peel the acetate off (like peeling plastic off new electronic stuff), you're left with a clean and neat surface on your cakes. I get my acetate from the pastry supply store that I mentioned above (http://www.dr.ca/acetate-roll-0.002.html) and it's not too expensive. If you reeeeeally don't want to buy acetate, I would use a handheld torch to release the rings from the frozen cakes, but I don't know how well that would work.

      Hope this helps!

  9. What a beautiful cake! It is gorgeous inside and out. I bet it is really delicious too. Definitely sharing!

    1. Thank you! It was definitely one of the best tasting things I've made :)

  10. How versatile is the cream when it comes to different flavors? I have really wanted to learn this type of cake technique and am having a hard time pinning down recipes made for this presentation.
