Baking Sunday: Concorde Cake


I was a big fan of Edd Kimber (aka The Boy Who Bakes) on the Great British Bake Off and he was a worthy winner of the show.  He has since released two baking books, both of which I really love.  This chocolate concorde cake is from the second of his books, Say It With Cake, which I'd thoroughly recommend.  In this day and age where anyone from telly that's ever appeared near an oven seems to have a baking book out, it's rare to find one with original ideas and definitive takes on classics.  What this book really excels at though is the big impressive show stopping numbers which I happen to love making.  I made this cake at an Edinburgh Bakers event rather a long time ago now (two further EB events have since passed, eep!), when the Edinburgh Bakers met the Glasgow Bakers.  With over twenty bakers attending there was a lot of cake that day!  There was friendly banter over which side would have the best cakes and the theme was, accordingly, show stopper cakes.  It was a fun theme to research with plenty of time spent on Pinterest and Tastespotting looking at beautiful cakes! I decided to make this cake as I was after something light but chocolatey and that would look beautiful and unusual.  This ticked all the boxes I think!  It consists of three layers of chocolate meringue, filled with a chocolate whipped cream mousse and covered with small meringue pieces.  I personally wanted to add a bit more of a wow factor and added an extra step of covering the cake in a chocolate mirror glaze before covering with the meringue pieces, which can be made in advance and reheated.  It adds another layer of texture to the cake and is darkly delicious.  I also added fresh raspberries between layers along with the chocolate mousse, just to freshen the cake up a bit.  It was a real hit on the day and I'm looking forward to when I have an occasion to make this again!

Concorde Cake
Recipe from Say it With Cake
Ingredients:
6 large egg whites
60g caster sugar
300g icing sugar
30g cocoa powder
icing sugar or cocoa powder, for dusting

For the simple chocolate mousse:
185g dark chocolate, finely chopped
500ml double cream

1 quantity of Chocolate Mirror Glaze, recipe below

Method:
1. Preheat the oven to 110° Celcius (90° fan oven) and line three baking sheets with baking parchment.  Using a 20cm cake tin as a template, draw a circle on each piece of parchment with paper, then turn it over so that the drawing is underneath.
2. Put the egg whites into a lcean, grease-free bowl, and, using an electric mixer, whisk until they form stiff peacks.  Slowly pour in the caster sugar and whisk until the meringue is stiff and glossy.  Sift the icing sugar and cocoa powder over the meringue and gently fold together, being as gentle as possible.
3. Spoon the meringue into a piping bag fitted with a 1cm wide plain piping tip and pipe three discs on the baking parchment using the drawn templates, piping in a spiral starting at the centre and working outwards.  Using the remaining meringue, pipe long strips onto theprepared rays alongside the discs.  Bake for about 1 hour and 40 minutes or until firm and crisp.  Turn off the oven and allow the merinuges to cool in the oven for two hours.
4. to make the mousse, melt the chocolate in a large heatproof bowl set over a pan of gently simmering water, making sure the base of the bowl doesn't touch the water.  Remove from the heat and leave to cool.  Whisk the cream to soft peaks the pour it into the bowl with the chocolate and whisk to combine.  The resulting mousse should be fairly thick and be able to hold its shape, but not so thick it can't be spread easily.  If it is too thick and looks overwhipped, pour in a little extra cream or milk and stir to loosen the mousse.
5. To assemble the cake, use a little of the mousse to stick the first meringue disc to a bardboard cake board or serving plate.  Spread about a third of the mousse over the meringue and then add another meringue and repeat the process.  Top with the final meringue and then coat the top and sides of the cake with the remaining third of the mousse.  Ensure the sides of the cake are smooth and even all over and freeze the cake for at least 30 minutes.
6. To finish the decoration, use a serrated knife to gently cut the meringue strips into pieces.  Take the cake from the freezer and slowly coat the cake with a third of the Chocolate Mirror Glaze.  Cover three times (if it becomes too sticky, reheat in the microwave on low for 30 seconds).  Freeze for 10 minutes and then trim the ends with a hot and sharp knife.  Lightly press the meringue strips over the cake, dust with either icing sugar or cocoa powder and place back in the freezer for an hour (this will soften the meringue slightly).  Thaw in the fridge before serving.

This looks amazing Katey, when is your book coming out? Ed's ombre cake is so pretty - I'd love you to make that :) xx

A-M-A-Z-I-N-G! You are a genius.

I got the first Ed Kimber book on your recommendation and use it a lot. Might have to buy the second one now too.

Thanks Marianthi :-) They're great books, the second one is perfect for special occasions (or just when you want to eat a massive and gorgeous cake). It also has biscuit recipes, I can't wait to make my own custard creams!

I am still thinking about that cake five months later! Your addition of raspberries was a stroke of genius :)
