This chocolate brownie mousse trifle has gone all Willy Wonka on you! Absolutely overloaded with chocolate, there’s crumbled brownies at the bottom smothered in velvety smooth chocolate mousse, and topped off with some milk and white chocolate curls.

Chocolate Brownie Mousse Trifle
You all are going to laugh your asses off at me and my stupidity because, let’s just say, this dessert isn’t as it was intended to be!
I did a Cadbury shop with #cbias and made sure that I was on time by completing my shop a few days before its due date. I even made the brownie bottom part of this dessert in the daytime so I had time for the mousse to set too.
Since I was doing a Cadbury shop (Mmmm, Cadbury), I thought I’d go the whole hog and buy their wonderful rich and indulgent dark chocolate, specifically Cadbury’s Bournville.
The giant man-baby is that much of a chocolate fiend that sometimes I have to stash chocolate away from him, run off and eat it under a blanket or something. He’s terrible. If he finds any of the chocolate that’s marked mine (because he’s already ate his portion), he’ll eat mine then deny it. Pffttt. Operation ‘hide chocolate’ is now underway!
My original intentions were to create some bars. A thin crispy brownie base covered in thick chocolate mousse and topped off with a thin layer of ganache and some chocolate curls then cut into bars. Sounds great doesn’t it? I thought so too.
Made the thin crispy brownie cookie-esque base, everything went fine. But I thought I’d freeze the brownie base for 15-30 mins to create some sort of a barrier so the mousse didn’t make the brownies soggy – kind of like a crisp brownie cheesecake bottom.
Opened the freezer and there wasn’t room, so with one hand I’m trying to rearrange the freezer and holding the brownies with the other hand.
The brownie pan had a removable base for ease of removing after everything had set, so I’m guessing you can imagine what happened next…
I dropped it!! Not only that, but it landed upside-down too! Argghh! 🙁
Thankfully the brownies landed on a clean area so I tried to salvage, but because it wasn’t cold it just tore into shreds… e.v.e.r.y.w.h.e.r.e!
I just stook there wondering what the heck to do next. There wasn’t time to make anymore brownies.
Then it hit me, why not crumble the brownies at the bottom, and make some sort of a trifle with the chocolate mousse?
It was decided.
But since time was not getting on and the deadline was so very close, I started panicking. Panicking is not good in the kitchen. And as my mother always used to say, “more haste equals less speed.”
Isn’t she always the wise one? I managed to lose tools, couldn’t find ingredients and even dropped a whole drawers of tools onto my feet. 😳
But all in all this dessert turned out great despite the stars not aligning for me. The mousse is wonderful and the brownies divine.
Such an indulgent luxurious treat even if it didn’t go the way I wanted. I can sit down and relax with a nice big chocolate brownie trifle or two. That should take the traumatic events away!

Chocolate Brownie Mousse Trifle
Yield: 4
Prep Time: 30 minutes
Cook Time: 30 minutes
This chocolate brownie mousse trifle is absolutely overloaded with chocolate. A crumbled brownie layer at the bottom, smothered in velvety chocolate mousse, then topped off with some milk and white chocolate curls.
Ingredients:
Brownies
- 200g (7oz) Cadbury Bournville dark chocolate, chopped
- 45g (3 tbsp) unsalted butter
- 2 eggs
- ⅔ cup granulated white sugar
- 1 tsp vanilla extract
- ¼ cup plain (all-purpose) flour
- ¼ tsp baking powder
Chocolate Mousse
- 200g (7oz) Cadbury Bournville dark chocolate, chopped
- 4 eggs, separated
- 2 tbsp caster (super-fine) sugar
- 225ml double (heavy) whipping cream
Directions:
- To make the brownie base, grease and flour an 8-inch square pan and set aside.
- In the microwave, melt the butter and chocolate in 1 minute increments or alternatively, in a double boiler. Whisk until smooth and allow to cool to room temperature.
- Using an electric mixer, beat eggs, sugar and vanilla until thick and pale – about 10-15 minutes.
- Fold in flour, baking powder and melted chocolate. Mix to combine. Set aside for 10 minutes to allow the batter to thicken.
- In the meantime, preheat oven to 180°C, 350°F, Gas Mark 4.
- Pour batter evenly into the square pan helping it along into the corners if need be, and bake in the oven for approx. 20-25 minutes.
- Allow to cool completely in the pan then transfer to a large bowl. Using a fork, crumble the brownies into a mixture of small and medium sized crumbs then place the crumbs in each trifle or dessert bowl, approx. ¼-⅓ full.
- To make the chocolate mousse, ut the chocolate into small chunks and place in a microwave safe bowl. Microwave in 30 second intervals until the chocolate has completely melted. Take care not to burn the chocolate. Allow to cool a little, then add the egg yolks, one at a time until fully incorporated.
- In a separate bowl, whisk the 4 egg whites until they start forming peaks. Add the sugar and continue whisking until stiff peaks form. In another bowl, whisk the cream until soft peaks form. Add the chocolate/yolk mixture to the cream in three stages until fully mixed, and fluffy.
- Using a big metal spoon or a spatula, fold in the egg whites into the cream/chocolate mixture until incorporated.
- Pour or spoon the chocolate mousse over the brownie crumbs until almost full then top with white and milk chocolate curls. Or whatever else you fancy.
- Place the desserts in the fridge for at least 3 hours to set, and enjoy.
