Chocolate Layer Cake Filled with White Chocolate Ganache~

by Liz Berg on January 8, 2013

I can hardly believe it’s been 26 years since I gave birth to my oldest. He wasn’t due till after New Year’s Day so since Bill was scheduled to make rounds over the holidays, I hopped in my little red Toyota and drove over the snow covered interstate to visit my parents. After celebrating  Christmas with my family, I returned home to work a full evening shift on the oncology ward…Bill and I were both exhausted  as we fell into bed late on the 26th after a full day of caring for patients. Hours later I awoke to labor pains and little Thomas was born before noon the next day…with a head full of wild brown hair and his dad’s beautiful eyes. I was smitten.

Like his father, he was an instant fan of chocolate….well, it did take a few months before he first indulged. As a toddler, I remember him pounding on the refrigerator door saying, “puddy, puddy, puddy” over and over. The stash of chocolate jello pudding cups I kept on hand for quick snacks had become a favorite treat. Birthdays demanded some sort of chocolate cake or pie….so when I spotted Diva Entertain’s Best Dark Chocolate Cake last month, I was reminded of this old favorite. I tweaked the recipe by adding a thick, decadent filling of white chocolate ganache and an extremely rich chocolate buttercream frosting. Although hubby jokingly declared the frosting to be “a chocolate party in my mouth” (after I told him, “good, really, really good” didn’t make for a very interesting blog quote), it was full of air holes, so not picture perfect. Still the combination of cake, filling and icing made for one spectacular tasting cake…maybe not up to my picky standards when it comes to looks, but definitely worth sharing due to the amazing flavor.

I sent the leftovers home with the grown up version of the guy below…and he and one of his roommates elected not to share it with any of their friends. I consider that the highest compliment!

Chocolate Layer Cake Filled with White Chocolate Ganache

Ingredients

  • 5 ounces semisweet chocolate, chopped
  • 1 1/2 cups very hot coffee
  • 3 cups sugar
  • 2 1/2 cups flour
  • 1 1/2 cups cocoa powder, sifted
  • 2 teaspoons baking soda
  • 3/4 teaspoons. baking powder
  • 1/2 tsp. salt
  • 3 whole eggs and 1 egg yolk, at room temperature
  • 3/4 cup canola oil
  • 1 1/2 cups buttermilk
  • 1 teaspoons vanilla
  • Filling:
  • 12 ounces white chocolate, chopped
  • 1/2 cup cream
  • Chocolate Buttercream Frosting (you may choose to make your favorite chocolate icing instead...it should be enough to frost a layer cake):
  • 2 cups butter, at room temperature
  • 7 cups powdered sugar, sifted
  • 1 cup cocoa powder, sifted
  • 1/2 cup cream (more or less depending on desired consistency)
  • 2 teaspoons vanilla

Instructions

  1. To make cake: Preheat oven to 325º. Coat three 8 or 9 inch cake pans with non-stick spray and then line bottom of pans with rounds of parchment paper.
  2. Put very hot coffee into a medium bowl. Add chocolate, let sit 5 minutes, then whisk until fully melted Set aside.
  3. In a stand mixer, combine 3 eggs and 1 extra yolk with the sugar and beat until light and pale yellow, approximately 3 minutes. Add the oil, buttermilk and vanilla and beat until combined. Add flour, cocoa powder, baking soda and powder and salt and beat until combined. Add chocolate mixture and mix until just fully incorporated.
  4. Divide batter between pans and bake in middle of the oven until a toothpick inserted in a center comes out clean, about 40-45 minutes. Remove to cooling rack. Cool for 5-10 minutes, then remove from pans and allow to cool completely. Carefully peel off parchment. Wrap and freeze one of the 3 layers to use at a later time. You can make a 3 layer cake, but you will need more filling and frosting.
  5. To make filling: Melt cream and white chocolate in microwave, stopping and stirring at 30 second increments till smooth and melted. Refrigerate mixture till cool and thick (you do not want the filling to be hard, but if it is too runny, it will run down sides of cake when second layer is placed over it).
  6. To make frosting: Beat butter with mixer till light and fluffy. Add powdered sugar, cocoa, cream and vanilla and mix till smooth and creamy.
  7. To assemble cake, place bottom layer on serving plate. Put filling in center of cake and spread to within 1/2 inch of edge. Top with second layer, flat side up. Ice top and sides with buttercream icing.

OMG, Lizzy! Not only does this cake look and sound amazing because I love white chocolate with chocolate cake, but I really, really love that you don’t skimp on the frosting and filling! Those thick layers of each are driving me crazy! I wish it was sitting right in front of me this very minute. Just give me a fork and I think I could eat half of it now..the rest later!

Happy Birthday to your son!! What a perfect birthday cake and treat. Lizzy, you worked until the last day of your pregnancy… tipping my hat off to you. I can’t imagine being on my feet that last month of pregnancy as a nurse. I know you are a hard worker…. I see all the hard work you put into your fabulous blog and all amazing things that come out of your kitchen. You are a force to reckon with… take a bow Mom… I think Moms forget to get patted on the back on a child’s birthday. You did all the hard work after all. ;)

Happy Birthday Thomas! My mom has her 3 baby’s birthdays this month. My brother just turned 34 yesterday, my sister is 29 today and I am 28 on the 19th! She was just telling us how much she can’t believe that she is old enough to have kids that are all so grown up!

What a lovely birthday cake!! I wouldn’t have shared it either! ;-)

I know exactly what you mean about the air holes in the frosting! I often have that problem especially with buttercreams! Looks great though, and we can’t even tell!

The cake looks amazing! My hubby would love it and his birthday is next month, so guess what he’s getting.

I enjoy reading the story about the day your son was born… so cute that he loves chocolates since when he was young. As a mom we remember some interesting moment of our kids and we treasure it even when kids are older… Happy Birthday to your son and I love your chocolate ganache filling!

Looks so…………. yummy!!!! Wow, I can see why they didn’t want to share it. I think our Nicks have similar tendencies when it comes to sweets. One time when my Nick was in college, I made a LARGE pound cake for him to share with his housemates. They never saw it because he hid it. He did share a bit with his girlfriend (who’s now his wife) but she told me that he only gave her a few “slivers”. What a brat! :)

Love the quote. Sometimes you just have to put a husband’s words back into his mouth and tell him to try again. I’m glad Tom(my) has gotten to the age where he realizes he doesn’t have to share everything. The cake looks delicious and very, very picture-presentable.

So your oldest has just turned 26? My oldest is about to turn 20. Both seem to have a healthy appetite for chocolate. What a gorgeous looking cake and I love how the centre is filled with a white chocolate ganache – it just adds to the decadence of this wonderful treat xx

Happy birthday to Tom and what a cake – no wonder they didn’t share, hehe. Yes, it also has to be said here that I could hardly believe it myself that you have a 26 year old when I met you in Paris last summer. You’re such a belle famille and the only layers you’ll find around you is with cakes!

Happy birthday Thomas. Time does fly, my eldest is almost a teen so it won’t be long before she grows up and flies the nest. The cake is stunning and so decedent. I love the white chocolate ganache filling too, that creamy touch of extra chocolate. Perfect.
