complicated chocolate peanut butter cake

Biscuit Joconde Imprime/Entremet – Peanut Butter and Chocolate all Decked Out

“You’re going to love the January Daring Bakers Challenge”.  That’s what Lis, the co-founder of The Daring Kitchen, said to me one day last December.  I was tied up in cassoulet, confit and a computer crash at the time, so the thought of baking anything was a welcome diversion, especially something I would love.  I’m very late in posting this – 4 days to be exact.  The freezer makes a great pause button.
The January 2011 Daring Bakers’ challenge was hosted by Astheroshe of the blog accro. She chose to challenge everyone to make a Biscuit Joconde Imprime to wrap around an Entremets dessert.
On reveal day, I think I squealed.  An entremet!   Plus, an entremet with a joconde (a decorative design baked into a light sponge cake providing an elegant finish to desserts/torts/entremets – formed in a ring mold,  Add a ‘La’ and joconde is the French name for the Mona Lisa – did she sponge off of people?  Bah Dum Bump) and decor pattern paste!  Ok, let’s go back a little further.  Once a year (I think), the Food Network televises the World Pastry Championship.  I watch in awe as tall toque topped teams of pastry chefs from many different countries compete to hold this honor… from the individual chocolates (bonbons and pralines) and plated desserts, to the sugar sculptures and chocolate showpieces, it’s all pretty amazing, but there’s one round that always holds my attention completely – the entremet.
A compilation of two of the three joconde imprimes I made.  Obviously, number three (bottom left) was the only one salvageable.
These pretty cakes of mousse, creams, genoise’s, feuilletines, dacqouise’s et al, are stunning works of art.  The flavors and fillings are always above and beyond your typical creative juices and they really are legitimate pieces of art!  The chefs, with their industrial strength, electric spray guns, (LOVE when pastry chefs find uses for the stuff you find at Home Depot or your local hardware store.  Joe with the dirt under his nails and half arm tan standing behind Pierre in his Burberry jacket with buffed nails, both purchasing a blowtorch), blasting bombes of mousse with chocolate and cocoa butter, while another pulls sugar into perfect, delicate flowers, gently placing them atop the shiniest caramel mirror you’ll ever see.  This is heaven to me.
Salted Peanut Dacquoise
Now, could I make an entremet that comes even a little, itty bit close to those?  Probably not, as my kitchen isn’t equipped with any electric spray guns, and I’m not equipped with those kinds of skills, but, I do have acetate, and chocolate transfer sheets!  It’s like playing grown-up when you’re a child – I was going to the land of make-believe to take on the role of a French pastry chef.  Oui Oui!
Naturally, as you’ve all come to expect on this blog, a few things went wrong before I could start building my entremet.  THE SQUIRRELS ATE MY JOCONDE PASTE RIGHT OFF THE DANG SILPAT.  Let me explain.  My freezer simply wasn’t freezing the design laden paste as hard as I felt it needed to be, so..since we’ve been hammered with snow and freezing weather the past 2 weeks, I decided to cover the baking sheet with the paste and my hard fought scraped out designs, and plant it on the snow outside.  Since when do squirrels like chocolate, seriously?  An hour later I go to get it and squirrels scatter, the top baking sheet covering pushed over, and only a minuscule corner of chocolate paste swirl left.  There were some chocolate, squirrel paw prints across the silpat..OK I though about it for a second, but only a second!
I really, really, really – REALLY wish I had  designed my joconde to match the chocolate transfer design on the hearts.  Simple scribbles with the wooden spoon handle, and the shoes would have matched the purse.
I didn’t freak, since I had plenty of paste left over for another try.  Again, I carefully scraped out a few designs on it, getting creative using biscuit cutters, a potato masher etc. I noticed everything was frozen solid on the second shelf of my freezer, so I moved everything and jammed the baking sheet in (yep, jammed, when a baking sheet doesn’t fit, so you find a way) and went on to make the sponge.  No snafu’s, no caveats, no problem!  I spread the sponge on top of the paste and into the oven it went.  Everyone said the baking time in the recipe that was provided to us by our host, was wayyy too long, as in crispy joconde too long, as in…divide baking time in half too long.  I obsessed and only baked it 6 minutes, not wanting to inch close to burnt spots - this sponge is all about the aesthetics. right!  The damn sponge tore when I gently pulled the silpat off.  SHEEET!
I had just enough paste left to make one more, but I had to make the sponge again. I was NOT spending time on intricate designs again – so, Lisa meet wooden spoon handle, wooden spoon handle, meet Lisa.  Squiggle, squaggle, sqwawggle.  Good enough.  If this one doesn’t work, I might actually give up on one of my most favorite challenges ever.  It tore a little (I’ve come to the conclusion that I need new silpats, they’ve been used to the point of silicone revolt and retreat), but I had enough to line the mold.  I had to piece together more than one strip, but it wasn’t too bad.  Not my original vision, but, hey, it’s amazing how quickly that changes when you have squirrels with refined palates.
Now that I’ve taken up almost a whole page with squirrel sabotage and other disasters, on to the good stuff.  My original vision for my entremet was ‘exotic’ fruit, sort of leaning toward tropical.  In fact, I even made some of the components for that first vision, but a peanut butter- milk chocolate theme struck like lightning and I couldn’t let it go.  I kept recalling this amazing peanut butter and milk chocolate mousse parfait created by The Dessert Truck in NYC.  Let’s just say, if you’re a fan of peanut butter, this is one of those desserts that haunt your senses forever once you’ve tried it.  Initially, I was going to add a fruit gelee insert and/or topping to add a peanut butter and jelly aspect to it, but then decided peanut butter and chocolate PLUS fruit gelee would sort of distract the palate from sinful and rich.  I was feeling the contrast in texture, but not so much in flavor.  I wanted pure peanut butter – chocolate goodness.  A chocolate gelee mirror was my last minute, final decision, after mulling for days and days over fruit or caramel (remember when Greg Brady didn’t choose Marsha or his GF for head cheerleader?).  Below are the components of my chocolate peanut butter entremet.
  • Biscuit Joconde
  • Milk Chocolate Ganache
  • Salted Peanut Dacquoise
  • Peanut Butter Milk Chocolate Feuilletine
  • Milk Chocolate Cremeux
  • Cocoa Genoise
  • Peanut Butter Mousse
  • Cocoa Glace (A nice, shiny chocolate ganache is great too.  Equal parts chopped chocolate and heavy cream, with a touch of light corn syrup.)
I was all over the place as far as the amount of ingredients for each component goes.  I used base recipes, changed them around, and hoped it was the perfect amount without any leftovers.   However, the genoise and chocolate cremeux (set with gelatin, which is not usually the norm, but it needed to be to carry the weight of the other components.  Didn’t affect the texture in a negative way) leave some leftovers, but is that really a bad thing?  Cocoa genoise - chocolate cremeux parfaits!  Also, the peanut butter mousse is a little different in that the heavy cream is not whipped and folded in.  However, it’s so light and creamy, you would never know it.  As rich as this entremet sounds, it’s actually quite light and not too sweet.  Wait, how could I forget the finale?
Asbestos handmade caramelized sugar corkscrews, ground salted peanut brittle (Equal parts sugar and water..cooked to a light caramel.  Stir in ground salted peanuts and cook until deep amber.  Spread on a parchment or silpat lined baking sheet and cut before it sets completely, or break apart when set), and tempered chocolate, which I poured and spread on a transfer sheet of gold scribbles, then cut out hearts, hearts because this baby was made with L-O-V-E .  A dusting of cocoa, and voila, my first, complete entremet.
By the way, below – can you tell which are the challenge recipes and which are not?  I’m metrically stunted – conversions make me cringe.

Milk Chocolate Ganache
1/2 cup chopped milk chocolate
1/4 cup heavy cream
Salted Peanut Dacquoise
- recipe by Nancy Olson via Food & Wine

1/2 cup confectioners’ sugar
2 large egg whites
1 Tablespoon granulated sugar
1/2 cup salted roasted peanuts, coarsely chopped
Milk Chocolate Peanut Butter Feuilletine
1/2 cup creamy peanut butter
2 tablespoons unsalted butter, softened
6 ounces good quality milk chocolate, chopped
*1 cup paillete feuilletine (OR rice krispies, or corn flakes, or crushed sugar cones) Although I suggested cornflakes as an acceptable substitute for paillette feuilletine, to me the taste and texture are quite different (they’re crushed french lace crepes called gavottes and are sweet with a caramel tone).  I purchased mine online, HERE.

2 Tablspoons water
1 cup milk
1 cup heavy cream
5 egg yolks
3 Tablespoons sugar

Peanut Butter Mousse
inspired by the NYC Dessert Truck dudes

2 teaspoons powdered gelatin or about 2 1/2 leaves gelatin
1/4 cup cold water
2 1/2 cups heavy cream
5 large egg yolks
5 Tablespoons sugar
1/2 cup salted smooth peanut butter
Cocoa Glace- courtesy of Daring Bakers, from the Yule Log challenge, Dec ’09
1 1/2 teaspoons powdered gelatin or 2 leaves gelatin
1/4 cup heavy cream
5 Tablespoons granulated sugar
1/4 cup water
1/3 cup unsweetened cocoa powder
1.In a clean mixing bowl whip the egg whites and white granulated sugar to firm, glossy peeks. Reserve in a separate clean bowl to use later.
2.Sift almond flour, confectioner’s sugar, cake flour. (This can be done into your dirty egg white bowl)
3.On medium speed, add the eggs a little at a time. Mix well after each addition. Mix until smooth and light. (If using a stand mixer use blade attachment. If hand held a whisk attachment is fine, or by hand. )
4.Fold in one third reserved whipped egg whites to almond mixture to lighten the batter. Fold in remaining whipped egg whites. Do not over mix.
5.Fold in melted butter.
6.Reserve batter to be used later.
1.Cream butter and sugar until light and fluffy (use stand mixer with blade, hand held mixer, or by hand)
2.Gradually add egg whites. Beat continuously.
3.Fold in sifted flour.
4.Tint batter with coloring to desired color, if not making cocoa variation.
Place the chopped chocolate in a stainless steel bowl. In a saucepan, heat cream over medium high heat until it just starts to boil. Immediately remove from heat and pour over chopped chocolate. Let sit for 2 minutes, then stir until uniform. Let sit until it reaches a soft, spreadable consistency.
Trace a 7-inch circle onto a sheet of parchment paper and lay it on a baking sheet. In a food processor, pulse the almonds with the confectioners’ sugar until they’re finely ground. In a bowl, using an electric mixer, beat the egg whites at medium speed until soft peaks form. Add the granulated sugar and beat until the whites are stiff and glossy, about 2 minutes. Using a rubber spatula, fold in the almond mixture. Spread the meringue on the parchment to fill the circle. Sprinkle the chopped peanuts on top. Bake for about 20 minutes, until lightly browned and firm. Turn oven off, prop the door open with a wooden spoon, and let dry in the oven for about an hour or two.
In a medium bowl set in a saucepan of simmering water, heat the peanut butter with the butter and milk chocolate, stirring constantly, until smooth and melted. Remove from the heat and fold in pailette feuilletine. Spread the mixture on top of the salted peanut dacquoise. Transfer to the freezer and let cool completely.
Bring the milk and the heavy cream to a boil in a saucepan. Meanwhile, whisk together the yolks and sugar; temper the yolks into the warm milk-cream mixture. Cook the custard, whisking constantly, until it coats the back of a spoon and registers 182 degrees on a thermometer. Add the melted chocolate and mix with an immersion blender. Stir in the melted gelatin and let cool until it thickens somewhat.
Preheat the oven to 375°F. Sift together the flour and cocoa powder. Place a heatproof mixing bowl over a pot of gently simmering water, combine the eggs and sugar, whisking constantly, until the mixture is lukewarm. Remove the bowl from the simmering water, and whip until cool. Fold in the dry ingredients, and then fold in the melted butter. Pour the batter onto a Silpat-lined sheet pan and bake for 6 minutes, or until done. Cut out one 6 to 7-inch round.  Save the rest for other preparations, or just snack on it.
1. In a bowl, dissolve the gelatin in the water and let stand for 5 minutes. In a saucepan, cook the cream over moderately high heat until it bubbles around the edge. In a medium bowl, whisk the egg yolks with the sugar. Gradually whisk the hot cream into the egg yolks. Pour the mixture into the saucepan and cook over moderately low heat, stirring constantly, until thickened, 3 minutes. Remove from the heat and whisk in the peanut butter. Melt the gelatin for 15 seconds in the microwave, then stir into peanut butter mousse base.  Let sit, stirring occasionally, until it thickens slightly.
Soften the gelatin in cold water for 15 minutes.  Boil the rest of the ingredients and cook an additional 3 minutes after boiling.  Add gelatin to the chocolate mixture. Mix well.  Let cool while checking the texture regularly. As soon as the mixture is smooth and coats a spoon well (it is starting to gelify), use immediately.
NOTE – This sets very quickly, so make it as soon as you remove the entremet from freezer for the last time.
1. Line an 8-inch cake ring or springform pan with acetate or parchment paper – make sure it’s at least 2-inches in height above the edge of cake ring – the peanut butter mousse will spill over, if not.  Line with strip of biscuit joconde, cut about 1-inch shorter in height than the top of the cake ring.
2.Place the circle of joconde biscuit at the bottom of the cake ring.  Spread or pipe with all the ganache then press the dacquoise - feuilletine disk on top of it. Pour partially set chcolate cremeux on top then freeze for about an hour.
3.  Remove entremet from freezer.  Brush both sides of the cocoa genoise with cocoa simple syrup then press on top of the chocolate cremeux.  Pour thickened peanut butter mousse on top of genoise. Freeze for another hour or two.
4.  Remove from freezer and pour cocoa gelee, slowly, over the top.  Let set, then refrigerate until ready to serve.
By the way, just found out the Peanut Butter Exhibition is up and running again, so I couldn’t resist, and entered this emtremet. Be sure to check it out and join up! Click the badge below to read about it and enter.
This was definitely a challenge, but so enjoyable and well worth the awe appeal, taste and layers of texture.  Surprise friends and/or family with one of these beauties at your next holiday, birthday celebration, or dinner party!  To see some of the most gorgeous entremets created by my fellow Daring Bakers, click on the links to their blogs, HERE.  Au Revoir, until next time!
