Chocolate Raspberry Charlotte Cake

Hello again!

I have had an extended absence from the blogging world, and for that, I am sorry! It has been a crazy last month and a half. Since my last post (almost a month ago! Agghh!) classes have ended, final exams are over, graduation is done, and I have been to, and am back from, Edmonton, where I marked diploma exams for a week.

After I got back from Edmonton, I got sick with a cold for a week, got better, went to Lethbridge, and began to clean out and move my classroom.

With all that insanity behind me, I decided to make something a little fancy before the insanity starts again. I have a friend’s wedding coming up, and I am making centerpieces and the cupcakes.

A charlotte cake is French in origin, usually with a sponge cake of some kind at the base, and ladyfinger cookies surrounding a fluffy smooth mousse filling.

I decided to make my own version of a charlotte. I did use recipes I found for all components, but put all the recipes together for my own version. I used the sponge cake and raspberry mousse filling from this site, and the chocolate mousse from here. Honestly, I should have halved the chocolate mousse recipe, because it made so much. I have reflected the proper measurements below, but if you want just a chocolate charlotte, double the recipe and use just the chocolate mousse as a filling.

The recipe I used consists of the following: a ladyfinger cookie outline surrounding the pan, a sponge cake base, a raspberry mousse, a chocolate mousse, and a middle layer of ladyfinger and sponge cake trimmings.

Here is a fancy dessert that (other than the sponge cake), requires no turning on of your oven. In fact, some versions of a charlotte use more ladyfingers as a base instead of a spongecake. This is a perfectly fine, and the only reason I didn’t use ladyfingers was because I ran out, so I made a sponge cake base. Them’s the breaks.

I will warn you: this dessert is not for the faint of heart! It’s a time and labour intensive dessert, but SO worth the effort.

Ingredients

Yield: 1 9 inch cake

For the sponge cake:

4 large eggs, room temperature
2/3 c. sugar
2/3 c. flour
¼ tsp. baking powder
3-4 tbsp. raspberry preserves, jam, or liqeur

For the raspberry mousse:

2½ c. frozen raspberries
½ c. sugar
2 tbsp. lemon juice
1 tbsp. unflavoured gelatin
2 c. heavy cream
6 tbsp. icing sugar

For the chocolate mousse:

6 oz. semi-sweet chocolate chips
1 c. heavy cream
¼ c. milk
¼ c. plus 2 tbsp. butter, at room temperature
3 eggs, separated
¼ c. sugar

For the lining and garnish:

2-3 dozen ladyfinger cookies (more if you use ladyfingers as a base as well as the lining)
1 c. heavy cream
Fresh raspberries (if desired)
Chocolate shavings (if desired)

To prepare, line the bottom of a 9 inch springform pan with parchment paper, and the sides of the springform pan with plastic wrap. Trim ladyfinger cookies ½ inch, so there is one flat edge. Place upright in the springform pan, sitting on the flat edge. If desired, line the bottom of the pan with more ladyfinger cookies, and use the cut pieces to fill in gaps.

If not lining the cake pan with ladyfinger cookies, begin preparation by making the sponge cake. In a 7 inch cake pan, line the bottom with parchment paper. Preheat oven to 350°F.

In the bowl of a mixer fitted with the whisk attachment, whip the eggs for 1 minute. Add the sugar, and beat again on high speed approximately 7 minutes, until light, fluffy, and 3-4 times the volume.

Sift together the flour and baking powder. Sift the flour mixture into the egg mixture in two additions, folding after each addition. Be thorough, and catch any hidden flour pockets, but keep the air in and do not over-mix.

Pour batter into the prepared pan and bake in the preheated oven for 23-25 minutes, until top is golden and springs back when poked lightly.

Let cool completely, then slice cake in half. My cake did not slice evenly, so I had one even layer, and I turned the remainder into a secondary “crumb” layer with my ladyfinger pieces in the middle.

For the raspberry mousse, combine the frozen raspberries and sugar in a medium saucepan. Cook, stirring occasionally, until the raspberries reach a jam-like consistency. Remove from the heat and strain through a sieve into a bowl, pressing on the fruit to extract as much liquid as possible.

Into the strained raspberry juice, stir in the lemon juice and gelatin. Transfer back to the saucepan, and over the warm burner whisk together until gelatin dissolves, then take back off the heat and let cool to room temperature.

In the bowl of a mixer with the whisk attachment, beat the heavy cream and the icing sugar together until thick and spreadable. Once the raspberry syrup is at room temperature, fold into the whipped cream a ¼ at a time, until all of the raspberry syrup is incorporated. Set aside, at room temperature.

For the chocolate mousse, in a heat-proof bowl add the chocolate, and melt over a double boiler or in the microwave for 30 second blasts, stirring constantly.

Add the milk, and whisk completely. Add the butter, and the egg yolks, whisking again until fully incorporated.

In the bowl of a mixer fitted with a whisk attachment, whip the cream until fluffy and thick. Fold in the chocolate mixture.

In a clean mixer bowl (with no grease whatsoever!), whip the egg whites until soft peaks form. Add the sugar, and whip egg whites into stiff peaks.

Fold egg whites into the chocolate mixture until cohesive.

To assemble the charlotte, in the prepared springform pan lined with ladyfingers, place the sponge cake in the base of the pan. Brush with the raspberry preserves, jam, or liqueur if using.

Spread half of the raspberry mousse in an even layer, and place in the refrigerator for 10-20 minutes to set up. Top with half of the chocolate mousse, and refrigerate again to begin setting up. Be careful not to knock the ladyfingers out of place.

If desired, use another layer of ladyfingers and cake crumbs on top of the chocolate mousse layer.

Top with remaining raspberry mousse, set for 10-20 minutes again, the remaining chocolate mousse, and refrigerate 3-4 hours until set.

To garnish, whip the cream into soft, thick peaks. Fill a piping bag with a star tip, and the whipped cream. Pipe onto charlotte, and garnish as desired with raspberries or chocolate shavings.
