TWD ~ Vanilla Chiffon Chocolate Mousse Cake

Utterly delicious Vanilla Chiffon Chocolate Mousse Cake

This week, our recipe for TWD~Baking With Julia, is by contributing baker Mary Bergin. It is for the
very lovely, Vanilla Chiffon Chocolate Mousse Cake. There were a lot of steps to this cake but, in the end it was well worth it!
 First, making a nut paste with toasted walnuts, that is then mixed with the melted chocolate. This is where I made my only mistake with this cake, by not paying attention to the details, which were many!  My mistake…you ask? I processed the nuts, added the melted chocolate, then the egg yolks and sugar syrup.  All was going well!  Next, I beat the yolks and folded them into the chocolate. While I was doing this, I asked my hubby to wash out my other mixer bowl (this recipe calls for a lot of them) so that I could whip the cream! About 15 minutes after I refrigerated the mousse, I realized I forgot to whip the cream…Oh No! I pulled it from the fridge, where it was beginning to harden,  placed it into the microwave for 10 seconds and all was saved. Well, kind of. My mousse is delicious, but is not as smooth and silky as it should be.  Other than that, things went smoothly, but what a mess was left behind! This recipe called for the food processor, the stand mixer, and all kinds of bowls, pots and pans! Was it worth it? The answer is a resounding yes!

This was a delicious cake! Spongy and light! The mousse was utterly divine! I made the whole version, and used my 17x12 sheet pan. It makes a huge cake, and will definitely feed more than the 6 servings the recipe says it will. This cake also took longer to bake, than the 10 to 12 minutes it calls for.  Mine was in the oven for about 20 minutes.  I shared a piece with my hubby, and froze the rest to serve to my Bunco group this weekend! I’m sure this will be a hit with the ladies! Happy Tuesday everyone!

The cake had a wonderful spongy light texture…and tasted luscious!
And it looked so pretty!
Even though the mousse was not as smooth and creamy as it should have been
Utterly divine! 

For the Cake
1 1/2 cups sugar
1 tsp. baking powder
1 tsp. baking soda
1/4 tsp. salt
4 large eggs, separated
1/2 cup vegetable or safflower oil
1/2 cup water
2 tbls. pure vanilla extract
2 large egg whites

For the Mousse
1 2/3 cups walnuts, lightly toasted
2 Tbls. walnut or safflower oil
5 ounces bittersweet chocolate, melted
3 large egg yolks
1/3 cup sugar
1/4 cup water
1 1/2 cups heavy cream

To finish the cake
Confectioner's sugar
Unsweeted cocoa powder
Caramelized walnuts (optional)
Sprigs of fresh mint (optional)
Makes 6 servings
Preparing the cake: Position rack in center of oven and preheat to 350°. Grease a 17 1/2" x 12 1/2" jelly roll pan with vegetable oil spray, and line with parchment or waxed paper. Spray the paper lightly but completely with oil.
Sift together 1 cup of the sugar and the other dry ingredients onto a sheet of waxed paper. In a large bowl, whisk together all wet ingredients except for the egg whites until blended. Add dry mixture slowly, whisking all the while. In a separate bowl, whip egg whites at a low speed with an electric mixer until they are foamy and form soft peaks. Increase mixer speed and gradually add remaining 1/2 cup sugar until whites are thick and shiny and hold peaks. Fold 1/3 of the whipped egg whites into the yolk mixture to lighten it, then turn the yolk mixture into the whites and fold it gently but thoroughly.
Pour and scrape the batter into the prepared pan, spreading it evenly with an offset spatula. Bake the cake for 10 to 12 minutes, until the edges start to pull away from the sides of the pan. Transfer the pan to a rack and allow to cool to room temperature.
Preparing the mousse: Process the walnuts and walnut oil in a food processor, fitted with the metal blade, until the mixture forms a paste (scrape sides as necessary). Add melted chocolate and process until blended. Set aside. Whisk egg yolks lightly by hand in a heavy duty mixer bowl. Bring 2 inches of water to a boil in a saucepan to be used as a double boiler with the mixer bowl, reduce heat and keep at a simmer while you proceed. In a small saucepan, combine sugar and water and bring to a boil. Remove pan from heat, and very slowly add the boiling syrup to the egg yolks, whisking mixture constantly. Fit the bowl to the saucepan of simmering water and continue to whisk mixture until it is foamy and hot to the touch. Remove bowl from heat and fit it into the mixer. With the whisk attachment, beat mixture on high until it is pale, holds a soft ribbon and is cool to the touch. With a rubber spatula, fold in walnut paste. Whip the heavy cream until it holds soft peaks. Fold lightly but thoroughly into walnut mixture. Refrigerate, tightly covered, until needed. Stir before using.
To finish the cake: Lightly sprinkle top of cake with confectioner's sugar and cover with a piece of parchment or waxed paper. Place an inverted jelly roll pan over the cake and turn the cake over. Remove the baking pan, peel off the paper, turn paper over and reposition it over the cake, Invert the baking pan, press against the cake, and invert it again so that the cake is right side up and resting on the inverted pan. Trim edges of the cake with a long thin knife. Keeping the 17" side of the cake in front of you, spread the chilled mousse over the cake, leaving 1 inch of the cake bare along the side closest to you, roll the cake up into an even roll, using the paper to help you move it along. When you come to the edge of the roll, the edges of the paper should meet.. Grab the edges and use the paper to help you scoot the cake into the center of the pan. Use a fork to tuck edges of paper under the cake and refrigerate for 2 hours (overnight if wrapped well).
To serve: Cut 5 strips of waxed paper and lay across the cake at evenly spaced intervals. Dust the cake with cocoa powder and a hint of confectioner's sugar. Lift off the paper. Place 1 caramelized walnut (optional) on each undusted stripe. Using 2 spatulas, lift cake onto serving platter and garnish with sprigs of fresh mint (optional).

  2. Your Bunco group will love this!!! Now on to the Paris-brest :)

  3. Your cake looks great. Wish my cake part had turned out like yours - mine was a little too moist.

  4. Looks divine! I forgot to add the raspberries - your pictures reminded me...I bought them when I went shopping on Saturday and just found them sitting in the back of the fridge...

  5. raspberries-the perfect touch! nicely done.

  6. Very lovely, Kathy

    It didn't make my make again list, but Joe sure loved it. (So many dishes...)

  7. Love chiffon cake! Your cake roll with chocolate mousse looks divine!

  8. Your chiffon roll looks lovely!!
    I like your raspberries addition, it gives a lovely contrast with the mousse!!!

  9. The roll looks so beautiful Kathy! I am sure everyone will be more than happy to taste it!

  10. The roll looks wonderful. The raspberries really bring out the chocolatiness ( if there is such a word). Yes the baking time is not quite right.

  11. This is beautiful. Would make a lovely Easter dessert. I'll have to make sure my husband is around for cleaning help if I try it ;-)

  12. Dear Kathy, I think this cake looks wonderful. I know that it would not last to freeze with my son and daughter, not to mention myself.
    Blessings and stay warm and cozy. Catherine xo

  13. Classy and delicious, stay warm while eating this :D


  14. Beautiful roll. Looks gorgeous and yummy! I loved this recipe. Yes, there were definitely a lot of dirty dishes, but I think worth it. :)

  15. Kathy, such an elegant chiffon cake, and the chocolate mousse filling is incredibly delicious!! You 'Doristas' have your baking challenges set out for you, I must say!

  16. So many pans, but yes, o so worth it. I froze 1/2 of mine. Will enjoy it later - again.
    Yours looks great.

  17. Ha! I did the same thing. Somehow I forgot the cream - this I did not notice until I was writing my post and re-reading the recipe. I thought I had lost the fluffiness by reheating the mousse mixture - it was rock solid after being in the fridge. The mousse still tasted good and the cake looked pretty, but was rather plain tasting. Maybe that is why?

  18. This is such a gorgeous cake!! Super fancy!

  19. Sounds heavenly, Kathy. Good save too!!! I have never been able to make a cake roll without it looking like "who did it and ran." Yours looks lovely and I'm sure it tastes delicious! Thank you so much for sharing...

  20. Lucky bunco group! I wish I still had some of this in my freezer. I agree - thought it was totally worth the time and dishes.
