The Cake Slice Bakers: White Chocolate Cake + a bonus cupcake!

When I woke up this morning, I peered out my window to discover a world swathed in a blanket of pristine, glistening, pure white snow. Few seasonal panoramas can compare to the beauty of fluffy flakes falling delicately upon unadorned tree branches and layers of freshly collected, bright winter ground cover. It seems only appropriate that the treat I bring you today is in keeping with mother nature’s color palette- a decadent, luscious yet light White Chocolate Layer Cake, this month’s assignment for The Cake Slice Bakers. I’m so glad to be back in action, baking with my fellow blogging buddies, who I’ve missed dearly during my recent absence from Hot Oven, Warm Heart. I can’t wait to catch up and see how everyone dolled up their latest cake. For my own creative spin, I decided to utilize some leftover whipped white chocolate mousse as a filling, and according to my tasters, that element was the perfect addition to an already delicious confection. (You’ll find the recipe below.) Unique and refined with a subtle flavor profile, this elegant cake would be a lovely dessert to grace your holiday table. I guarantee it will disappear well before the snow!

Made of cocoa butter, sugar, milk solids, vanilla, and lecithin, white chocolate is technically not considered chocolate at all, due to its lack of chocolate liquor. It first appeared in Switzerland in the 1930’s, invented by the Nestle Corporation as a way to use up excess cocoa butter, and was later popularized in America with the distribution of Nestle’s Alpine White Chocolate Bar. To select a good quality white chocolate, make sure it contains cocoa butter rather than the substandard brands made with hydrogenated vegetable fat. The inferior preparations might be less expensive, but they also lack the cocoa butter’s characteristic rich, creamy flavor. The tell tale difference between the two is in the color- true white chocolate has a deeper ivory hue, in contrast to the bright white shade of the imitation variety. When working with white chocolate, a good tip is to treat it with care and always melt it over low heat, which will help prevent the common problems of scorching and seizing.

This month’s Cake Slice Baker’s selection features white chocolate in each of the cake’s components: a healthy dose in the batter, more mixed into the cream cheese frosting, and in my case, a little extra in the improvised mousse filling. Instead of baking in the recommended 9” pans, I decided it was the ideal opportunity to break out my adorable new 6” rounds and give a miniature sized version a go. Of course, I called upon my super knowledgeable friend Steph of the famed A Whisk and A Spoon, who has graciously acted as my personal source for any and all baking 911 needs, and she shared her always reliable tips and tricks. I learned that you can pretty much take any standard 9” cake recipe, and successfully cut it in half to produce an irresistible 6-incher, perfect for a small gathering or in my case, just two grateful tasters. Steph pointed out that the key with such recipe modifications is in the baking time. It can vary greatly from the larger version (she recommends checking about 10 minutes early) OR be nearly identical. That was the case with my mini white chocolate cakes, which were ready to come out of the oven at 27 minutes (right in line with the 25-30 minutes suggested in the recipe instructions.) To test for doneness- I recommend adhering to the instructions- the cakes are ready when golden brown, spring back when touched gently in the center, and are beginning to pull away from the sides of the pans. I guess I should have headed the warning mentioned in the book’s Baking 101 section that said checking a cake too soon with a toothpick can cause it to collapse. Whoops! That’ll teach me to be overzealous! But the slight imperfection of a thin concave marking was easily hidden with mousse and frosting, and the cake was none the worse for ware. As with every baking experience, I learned for next time.

And I can’t forget about the bonus cupcake I promised you- it is most definitely a keeper! When my aunt requested something chocolate for her 60th birthday celebration, I knew immediately I had just the thing. By revamping my most-well received cake (of all time!) into cupcake form, I created a batch of knock-your-socks off Super Fluffy Chocolate Cupcakes with White Chocolate Mousse Filling and Fudgy Milk Chocolate Frosting. If the name is any indication- they were a hit! I feel privileged to share this very thoughtful and incredibly kind comment my dear cousin Sheila left on Hot Oven, Warm Heart after the party (It ended up on the “About” page, since I hadn’t posted yet about these yummy morsels. I’m glad to put it in it’s rightful home! Thanks so much Sheil, your words mean the world to me- I love you!)

“Wow is all we can say about the wonderful chocolate cupcake filled with delicious white chocolate mousse! A work of art, but more than that, an explosion of flavors in our mouths. You are truely an artist. Would love to have Gourmet Magazine taste these. Hmmmmm yes indeed. If we still had our restaurant, you would be our baker. Thank you and keep baking, and of course we will be your tasters.

Here are the recipes I used, which I highly recommend you try!

Ina Garten’s “Beatty’s Chocolate Cake” recipe
*This recipe makes exactly 2 dozen cupcakes- I’ve baked them this way twice, and both times they took 22 minutes (a toothpick should come out with no crumbs attached- don’t worry, they shouldn’t collapse!). It’s most definitely my go-to chocolate cake recipe, and has never let me down!

White Chocolate Mousse
from Sky High: Irresistible Layer Cakes by Alisa Huntsman and Peter Wynne

Ingredients:
4 ounces white chocolate, chopped
1 cup heavy cream
1 egg white
1 tbsp sugar

Directions:
Melt the white chocolate with ¼ cup cream in a double boiler. Whisk until smooth. Remove from the heat and let the white chocolate cream cool to room temperature.

When it has cooled, beat the remaining ¾ cup cream until soft peaks form. In a clean bowl whip the egg white with the sugar until fairly stiff peaks form.

Fold the beaten egg white into the white chocolate cream, then fold in the whipped cream until blended. Be sure not to over mix.

*I only used half of this recipe to fill the cupcakes, but if you have any left over, don’t let it go to waste! Before I had my light bulb moment when I thought to put the rest in my White Chocolate Cake, I planned on making these Whoopie Pies– which will still be on my list!

Cook’s Illustrated’s Foolproof Chocolate Frosting
as seen on America’s Test Kitchen

Note: This frosting may be made with milk, semisweet, or bittersweet chocolate. (*For these cupcakes, I prefer a frosting made with milk chocolate.) Cool the chocolate to between 85 and 100 degrees before adding it to the butter mixture. The frosting can be made 3 hours in advance. For longer storage, refrigerate the frosting, covered, and let it stand at room temperature for 1 hour before using.

Makes 3 cups to frost one 9-inch 2-layer cake (or about 2 dozen cupcakes)

Ingredients:
20 tablespoons (2 1/2 sticks) unsalted butter , softened (60 to 65 degrees)
1 cup confectioners’ sugar (4 ounces)
3/4 cup Dutch-processed cocoa
Pinch table salt
3/4 cup light corn syrup
1 teaspoon vanilla extract
8 ounces milk chocolate , melted and cooled slightly (see note)

Directions:
In food processor, process butter, sugar, cocoa, and salt until smooth, about 30 seconds, scraping sides of bowl as needed. Add corn syrup and vanilla and process until just combined, 5 to 10 seconds. Scrape sides of bowl, then add chocolate and pulse until smooth and creamy, 10 to 15 seconds. Frosting can be used immediately or held (see note).

If those cupcakes don’t put a smile on your face, take a look at my baby in her holiday best! Much love to you all and warmest wishes for a glorious holiday season!

  1. Um, hi, YUM.

    Joy, your cake looks delicious! I can’t wait to read the write up. And can we talk about the text on the pictures?

    I’m glad you’re back!

  2. Hi Joy, a white chocolate cake sounds divine; I’ll look forward to reading more about it. I hope you are feeling better.

    I actually stopped by to tell you that I made David Lebovitz’s toffee recently, after you had recommended it, and just posted about it. I’m so happy you had posted the recipe when the SM group made toffee. I have to say, it was a much more pleasant candy-making experience and a keeper of a recipe!

  3. Hey Joy,

    As always a wonderful post, and an even more wonderful treat. The white chocolate cake was as good or maybe even better than it looks in the pictures. The smaller size was perfect for your two always available tasters. Every morsal was eaten.

    As for the cupcakes, I heard a few people at the surprise party (that you made them for), say that they were only going to have a little taste, as they were expecting them to be too rich. Inevitably each and every one, was eaten down to the cupcake liner, and I had to hid one to take home with me.

    I never have to hesitate to take something that you make with me to share, as each and everything is total YUM!! (I only have to be willing to part with the treaures)
    Love you,
    Mommy

  5. Hi Joy. You’re back!! Yay! I hope you’re feeling better.

    I love *real* white chocolate. Your cake and cupcakes look delicious. How nice of you to make them for your aunt’s birthday 🙂

    I’ve been keeping busy. Baking a lot. Especially now that my kitchen remodeling is done (check out before and after pics on my blogs). I’m totally loving my new convection oven 🙂

    Happy holidays and a blessed 2010.
    Looking forward to hearing from you soon.
