August 31 is my friend Christine's birthday. And on Sept 2, it is my cousin-in-law Matthew's birthday! On Sept 1, we have a dinner party at my place and I made this cake to celebrate their birthday together in this occasion. Since my friend Christine does not like cheesecake, and Matthew is OK with anything. I decided to make them a chocolate mousse cake. And chocolate mousse cake is also one of my favorite desserts of all time!!! ^_^
(9" Square cake)
For the chocolate cake layer:
1 stick (112 g) unsalted butter
1 1/3 cups (257 g) sugar 1/2 cup + 2 tablespoons (56 g) cocoa powder
2 large eggs
2 oz (56 g) dark chocolate, melted
1 3/4 cups (210 g) all-purpose flour
1 teaspoon (4 g) baking powder
3/4 teaspoon (3 g) baking soda
1/4 teaspoon (1 g) salt
1/2 cup (118 ml) water
1/2 cup (118 ml) milk
For the dark chocolate mousse:
1 teaspoon (3 grams) powdered gelatin
2 tablespoons water
1/2 cup (105 g) whole milk
6 oz (175 g) good quality dark chocolate, finely chopped
1 1/4 cup (280 g) heavy cream
For the white chocolate mousse:
1/2 cup (105 g) whole milk
6 oz (175 g) good quality white chocolate
1 teaspoon (3 grams) powdered gelatin
2 tablespoons water
3/4 cup (180 g) heavy cream
For the chocolate glaze and sauce: (I follow this recipe, but the glaze melt)
4 oz (112g) dark chocolate, finely chopped
1/2 cup (80g) heavy cream
3 tablespoons light corn syrup
1 tablespoon vegetable oil
1/2 teaspoon vanilla extract
(I will try to use gelatine next time to settle the glaze layer)
3g (1/2 packet) gelatin
15g (1 tablespoons) water
Directions:
Make the Chocolate Cake base:
(I use cake mix this time-lazy and lack of time)
- Preheat oven to 325 degrees F.
- Melt the chocolate. Melt it in the microwave in 30-second
intervals. Chocolate burns easily, so stir between every zap. Set it aside for the moment.
- Using a tabletop or handheld electric mixer, beat the butter, sugar, and cocoa
powder together on medium high speed until smooth, creamy and fluffy, about 3 minutes. Hard to see with the cocoa in
the bowl, but this is what it looks like 3 minutes later.
- Add the eggs, one at a time, until each one disappears into the mix.
- Pour in the melted chocolate.
- In a medium bowl, stir together the dry
ingredients, which include flour, baking powder, baking soda and salt. Stir ‘em
up good.
- Combine the milk and the water and microwave until hot, about 45 seconds.
- Drop the dry ingredients into the mixing bowl and mix on low speed until MOSTLY combined, and then, with the machine still running, pour in the hot
water/milk mixture
- Pour it into pan that’s been first sprayed with nonstick
cooking spray and lined with parchment. Bake in your preheated oven for about 18 minutes.
(Cake layer can be made a day ahead, if you’d like to break up the labor of
this recipe. Wrap the whole thing, sheet pan and all, with plastic very well,
and refrigerate.)
Make the dark
chocolate mousse:
- First we’ll rehydrate the gelatin (otherwise known
as “bloom” the gelatin.) Sprinkle it evenly over a small bowl with the
water. In 5 minutes, it’ll have slurped up the liquid and will look, well, gelatinous
- Next heat up the milk to a simmer in a small sauce pan. Turn OFF the heat (This is important. When subjected to high heat, gelatin
deteriorates and turns grainy) and then scrape the gelatin blob into the hot
milk. Swirl the pan around until it’s completely dissolved.
- Pour this milk/gelatin concoction over the finely chopped chocolate and let it rest for 2 minutes. The heat from the milk will melt down the
chocolate. Whisk it up into a smooth pool of goodness. Set it aside and let it cool to
lukewarm.
- Now, with a clean whisk, whip the cream.
- A soft peak is perfect. This texture is easiest to
fold into the chocolate.
- Scoop about a third of the whipped cream into the
chocolate. Since the chocolate is kind of dense and heavy, this will help
lighten it up. When we fold in the rest of the cream, it won’t deflate as
much.
- Then add the rest of the whipped cream, and gently
fold that in.
- Pour the mousse into the molding pan. Put the
whole tray in the freezer while you make the white chocolate mousse.
Make the white
chocolate mousse:
- Here are the ingredients. They’re pretty much the
same as the dark chocolate mousse, except there’s less cream to whip.
- The method is also the same as the dark chocolate
mousse, and will feel like old hat by now.
- Again, we bloom the gelatin.
- Simmer the milk
- scrape in the gelatin, and let it dissolve.
- The gelatin/milk mix gets poured over the white chocolate and we whisk it up into a smooth pool.
- Whip the cream to soft peak stage and fold a third of it in to lighten.
- It gets poured into the molds, most of the way up.
Leave some space on top, about 1/8″ – 1/4″ for the chocolate glaze. Pop the tray
back into the freezer while you make the glaze and garnish.
chocolate sauce/glaze:
- bloom the gelatin
- Pour the heavy cream, corn syrup and oil into a
microwave-proof cup and nuke until almost boiling (you might be able to see it
gurgling in the cup), about 45 seconds. It will look curdled but pay it no mind.
Stir it up to blend.
- scrape in the gelatin, and let it dissolve.
- Pour over the chocolate and allow to sit for a minute to
melt it all.
- Whisk everything until completely
smooth.
- Wait until the sauce cools to lukewarm (so it doesn’t
melt down the mousse), and carefully pour sauce onto the tops of your molds.
It’s going to start setting almost immediately on contact from the cold, so work
fast. Back into the freezer they go for at least 4 hours, to fully set. Once
set, if you plan to keep them frozen for a while, be sure to wrap the tray very
well to keep the cakes from absorbing strange freezer
flavors.
Gettin’ ready. You can see how sweaty my
eggs are in the photo. All cold ingredients should be at room
temperature for better incorporation. Preheat oven to 325 degrees F.
