Ingredients
For the cake layers:
- 2 1/3 cups cake flour
- 1 1/2 tsp baking soda
- 1 tsp table salt
- 1 oz unsweetened chocolate, coarsely chopped
- 1/2 cup (1 stick) unsalted butter, at room temperature
- 2 1/3 cups light brown sugar, firmly packed
- 3 large eggs
- 2 tsp pure vanilla extract
- 1 cup sour cream
- 1 cup boiling water
For the ganache frosting:
- 24 oz bittersweet chocolate (70% or 72% cacao), finely chopped
- 1/2 cup (1 stick) unsalted butter, at room temperature, cut into 8 pieces
- 2 1/2 cups heavy whipping cream
- 2 tsp pure vanilla extract
- 1/4 cup light corn syrup
For the truffle filling:
- 8 oz semi-sweet chocolate, coarsely chopped
- 3 oz unsweetened chocolate, coarsely chopped
- 1 1/2 cups (3 sticks) unsalted butter, at room temperature
- 1/2 cup heavy whipping cream
- 6 large egg yolks
- 2/3 cup powdered sugar, sifted
- 1 tbsp pure vanilla extract
- 2 tbsp Grand Marnier orange liqueur (optional)
Instructions
- To make the cake: Preheat oven to 350° F. Arrange 2 oven racks in the upper and lower third positions of the oven. Line 2 12×17-inch baking sheets with parchment paper or silicone baking mats and coat with non-stick baking spray. Set the pans aside.
- Sift the flour, baking soda, and salt into a medium bowl and set aside.
- Place the chocolate in a medium heatproof bowl and microwave at 30 second intervals, stirring between each one, until the chocolate is completely smooth.
- In a stand mixer fitted with the paddle attachment, beat the butter and sugar at medium-high speed until light and fluffy, about 2 minutes.
- Add in the eggs one at a time, beating for 30 seconds at medium speed after each addition, and scraping down the sides and bottom of the bowl as needed. Mix in the melted chocolate and vanilla until fully incorporated.
- With the mixer on low, stir in the flour mixture and sour cream in 5 alternating additions starting and ending with the flour, beating each one at medium speed for 20 seconds. With the mixer on low, slowly pour in the boiling water and slowly turn the mixer up to medium until the water is completely incorporated, about 30 seconds.
- Pour the batter in a large measuring cup and then pour half of the batter into each of the prepared baking sheets. (Alternatively, you can use a kitchne scale to weigh the batter in the pans to ensure they are equal.)
- Bake for 7 to 12 minutes, until the center of cake is springy when lightly touched and a toothpick comes out clean from the middle of the cake. Transfer the baking sheets to wire racks and allow the cakes to cool for at least 30 minutes.
- To make the ganache: Place the chocolate and butter pieces in a medium heatproof bowl. In a small saucepan, heat the cream over medium heat just until it begins to form tiny bubbles around the edge of the pan and it starts to steam. Immediately pour the cream over the chocolate and butter and let it sit for 2 minutes. Stir until the chocolate is completely melted. Mix in the vanilla extract and corn syrup until the chocolate is smooth and glossy. Allow the ganache mixture to sit at room temperature for at least 2 hours. Do not refrigerate it to speed up the process or it will become too hard.
- To make the truffle filling: Add both chocolates, the butter, and the cream to a medium heatproof bowl and microwave at 30 second intervals, stirring between each one, until the chocolate is completely smooth and all are fully incorporated. Allow the mixture to cool completely.
- In a stand mixer fitted with the whisk attachment, whip the egg yolks at high speed for 5 minutes, until thick, glossy, and light in color. Add in the chocolate-butter-cream mixture and beat on medium-high for 1 minute. Add the powdered sugar, vanilla extract, and Grand Marnier (if using) and whip on medium speed just until incorporated.
- To assemble: Place a layer of wax paper over the top of each of the cooled cakes and invert the cakes onto a work surface. Cut each cake into three long 4-inch wide pieces (you’ll cut the cake from short end to short end in 3 long pieces).
- Place 1 cake layer on a serving platter and spread 1/5 of the frosting on top and top with another cake layer. Repeat with the remaining cake layers and frosting, ending with a cake layer. Cover the cake with plastic wrap and refrigerate until firm, about 2 to 3 hours.
- Remove the cake from the fridge and frosting the top and sides with the ganache. To make clean slices, dip a serrated bread knife in hot water each time you make a slice. Slice the cake horizontally (short-ways).
Do Ahead: The ganache can be made the night before you need it and kept at room temperature (covered) until you’re ready to serve the cake. The entire cake can be made and kept in the fridge for up to 3 days or in the freezer for up to 1 month before serving.
Storage: Keep leftovers well-wrapped in the refrigerator for up to 1 week or in the freezer for up to 1 month.

Wonderful post, Tara!! I love it! 🙂
You hit on a huge part of the blogging puzzle. Community is a major piece of it. We all have our neighborhoods in the blogging community, but as a whole, we understand each other and why we do this. Beautifully written! Best of luck to you!
Great post! 🙂
lovely post have fun
What a lovely ride you’ve had through the past few years! I’ve had so much fun getting involved in the blogging community.. its refreshing and exciting to find so many people out there who love food as much as I do 🙂 Good luck with the challenge- that cake looks decadent and delicious!
Beautiful post! Good luck-
Billie
this is a great post tara 🙂 can’t agree with you less on the effect of community on food blogging. all the best!
Great post Tara! Good luck!
Great post! I’m so glad the cake I chose turned out to be what it was for you. And I loved seeing your progress throughout the years.
Stopping by to see who else has entered the competition. I had the same problem, trying to find the right words. Afterall, to say all you need to say in one post? Quite a challenge!
But your cake? Deeeeelish and very drool worthy!
Anyway, looks great, reads well and good luck!!
As a fellow FB FP involved with PFB (wow – lots of acronyms!), I’m loving this contest already. Despite the inherently competitive nature of a competition dangling a $10K grand prize, it’s given me the opportunity to find bloggers (such as yourself) that I may never have stumbled across. Good luck to you, I look forward to reading more of your posts in the future!
Well, I’m certainly you found this community! Great to know you better and I’m daydreaming about that cake!
What a wonderful post and quite a different angle than some of the other PFB posts I have read. I wish you the best of luck with this challenge and hope you get to stick around for quite a few rounds :o)
Beautiful post. You nailed it-the community is what makes food blogging so special. I am learning all about that now! Good luck!
P.S. I too started the challenge a hundred times only to erase it and start again!
Great post! Good Luck !
Wow! You do have what it takes to go to the next phase! Can’t wait to see your next post!
What a great post. I’m a new food blogger, but I can already tell that I’m part of a great community and I have a LOT to learn!
Lovely post! Good Luck!
You are a great storyteller…weaving your thoughts through your experiences.
Excellent work on the first challenge! I can see how far your blog has come and how you have grown as a food blogger. And I’d love to have a slice of that cake! 🙂
What an excellent post! I love all the stories of community!
Best of luck in Project Food Blog!
And, what a beautiful cake!
I’m also participating in PFB and looking forward to reading everyone’s great entries! Good luck!
Such a wonderful inspiring post! Isn’t it amazing what we can accomplish when we have such a supportive community? Good luck in the contest!
I agree with you, it was the hardest post I have ever written… Tooting my own horn is not something I am accustomed to and I am sure I skirted the question. 🙂 Your post is wonderful, really inspiring!
I love the idea of us all being part of a community – one that so far I have found mostly supportive 🙂
Great post, I was thinking the same thing when I wrote mine! Happy to send you one of my votes! Good Luck, wishing you the best! Btw, you have some amazing photos, I’m a little envious!

It really is all about community! The challenge has opened so many new-to-me bloggers who I look forward to following. I’d like to see you in the next round and am casting one of my votes.

Darling Dear… you for sure have my vote… and you are right… that cake is TOTALLY 7th Heaven! ♥♥♥ Megan@foodalution.com
OMG, that cake! Please send two slices, ASAP! Seriously, though, I really like the community theme of this post and how important the community is to you and how important you are to the community. Community is such a rewarding part of blogging both for the pat on the back when you’re having a down day and for encouraging you to go outside your comfort zones. Best of luck in the challenge – hope to see us both in Round 2! -Sarah
