Chocolate Truffle Cake

You didn’t think I’d let my Moms birthday go by without a cake, did you?

I usually decide on a type of cake myself, but this time I decided to ask my mom what she wanted. She said chocolate, chocolate mocha. So I got to work looking for the perfect recipe. The perfect recipe turned out not to exist, but I was inspired by two chocolate truffle cake recipes, one from Food and Wine and the other from Anna Olson. I used Anna’s cake recipe so that the cake would have some coffee flavour, and I used the ganache filling from the Food and Wine recipe. I added espresso powder to the dark chocolate layer, and kahlua to one of the white chocolate layers. Unfortunately I don’t think I used enough coffee, the chocolate flavour kind of took over. Despite not being very mocha-ey, the cake was delicious.

Before I get to the recipe, I have a blog award to share. Alina at Russian Season was kind enough to give me the Stylish Blogger Award.

Alina’s site is full of great Eastern European dishes, if you haven’t already you should definitely visit her site. So I’m giving the award right back to her and to these blogs I’ve recently discovered.

  4. In a separate bowl, beat eggs on high-speed for 1 minute. Slowly add the oil, buttermilk and vanilla.
  5. Alternate adding the flour and coffee mixture to the eggs.
  6. Taste the batter, it’s like pudding.
  7. Pour the batter into the prepared pan, bake for 25 to 30 minutes then let cool completely.
  8. Make the chocolate ganache. Heat the cream until small bubbles start to appear. In a small bowl pour over the chocolate and stir until the chocolate has completely melted and is shiny. Chill for 1 hour.
  9. Make the white chocolate Kahlua ganache: Melt the white chocolate over a double boiler. Heat the cream and butter until small bubbles appear then pour into the melted chocolate. Stir until completely combined. Stir in the Kahlua. Chill for 1 hour.

Spread the white chocolate Kahlua ganache on the cake. Top with the third layer of cake, and spread the white chocolate ganache. Top with the final layer of cake and ice with the remaining ganache.
  12. Let the cake set for at least 1 hour. When serving slice with a hot knife.
