EATS: Birthday Cake!

December birthdays kind of have it rough. I mean, with all the holidays that happen towards the end of the year, it's kind of hard to schedule a birthday party. Which is why the December birthday have to do it between Thanksgiving and Christmas/Hannukah/Kwanzaa or just not at all. But what fun would that be? My good friends Natalie and Hess both celebrated their birthday early in December, and so I decided to make them both birthday cakes! One was a success and the other one was very much the opposite of that (more on that later). Either way, they were both learning experiences. Starting with my successful cake, I made my friend Natalie a yellow birthday cake with chocolate ganache frosting from Joanne Chang's new cookbook, Flour. Luckily, Joanne has been very generous with her recipes over the years, so I am able to post her recipe here. But the cake! Buttery, vanilla-y, home-y. So good. Like the box version, but much better. And the grown-up spin is the dark chocolate ganache which compliments yellow cake so nicely. Happy Birthday Natalie! I wish I could post the picture of Natalie with her birthday cake, but my friend Eric can't seem to get it off his phone. Oh well. I will instead post a couple of pictures that I think are representative of her.

Natalie is smart.

Natalie is beautiful

And, she has the the sweetest, sunniest personality!

For the cake: * 1 1/2 cups (3 sticks/342 grams) unsalted butter, at room temperature * 2 cups (400 grams) granulated sugar * 3 eggs * 3 egg yolks * 1 teaspoon vanilla extract * 3 cups (360 grams) cake flour * 1 teaspoon baking powder * 1/2 teaspoon baking soda * 1/2 teaspoon kosher salt * 1 cup (240 grams) nonfat buttermilk

For the chocolate ganache frosting: * 12 ounces (340 grams) semisweet chocolate, finely chopped * 1 cup (240 grams) heavy cream * 1 cup (2 sticks/228 grams) unsalted butter at room temperature * 1 cup (140 grams) confectioners' sugar * 1/4 teaspoon kosher salt * 1/2 teaspoon vanilla extract

For the cake: Position a rack in the center of the oven, and heat the oven to 350 degrees. Butter and flour two 8-inch round cake pans. Using a stand mixer fitted with the paddle attachement (or a handheld mixer), cream together the butter and granulated sugar on medium speed for 3–4 minutes, or until light and fluffy. (This step will take 8–10 minutes if using a handheld mixer.) Stop the mixer a few times and use a rubber spatula to scrape the sides and bottom of the bowl and the paddle to release any clinging butter or sugar. in a small bowl, whisk together the eggs, egg yolks, and vanilla just until combined. On low speed, slowly pour the egg mixture into the butter mixture and mix just until incorporated. Scrape the bowl and paddle again, then beat on medium speed for 20–30 seconds, or until the mixture is homogeneous. In a medium bowl, sift together the flour, baking powder, baking soda, and salt. On the lowest speed, add about one-third of the flour mixture to the egg-butter mixture and mix just until barely combined. Immediately pour in about half of the buttermilk and continue to mix on the lowest speed until the buttermilk is almost thoroughly incorporated. Stop the mixer and scrape the sides and bottom of the bowl well. Again on the lowest speed, add about half of the remaining flour mixture and mix just until barely combined. Add the rest of the buttermilk and mix just until combined. Be careful not to overmix. At this point, it is best to finish the mixing by hand. Remove the bowl from the mixer stand and, using the rubber spatula, fold in the remaining flour mixture just until the batter is homogeneous. As you fold, be sure to incorporate any batter clinging to the sides and bottom of the bowl. Divide the batter evenly between the prepared cake pans. Bake for 40–50 minutes, or until the tops are golden brown and the cakes spring back when pressed in the middle with a fingertip. Let cool completely in the pans on wire racks. (The cooled cakes can be tightly wrapped in plastic wrap and stored in the freezer for up to 1 week. Thaw at room temperature, still wrapped tightly in plastic wrap.) For the chocolate ganache frosting: While the cake layers are cooling, put the chocolate in a medium heat-proof bowl. In a small saucepan, scald the cream over medium-high heat (bubbles start to form around the edge of the pan, but the cream is not boiling). Pour the hot cream over the chocolate and let sit for about 1 minute, then slowly whisk together the chocolate and cream until the chocolate is completely melted and the mixture is smooth. Let sit at room temperature for 1–2 hours, or until completely cool. (Or, refrigerate the ganache until cool, about 30 minutes, whisking every 10 minutes). Fit the stand mixer with the paddle attachment (or use a handheld mixer) and beat the butter on medium-low speed for 10–15 seconds, or until smooth. Add the confectioners' sugar, salt, and vanilla and continue to beat on medium-low speed for about 2 minutes, or until the mixture is fluffy and smooth. Stop the mixer a few times and use a rubber spatula to scrape the bowl and the paddle to release any clinging butter or sugar. On medium speed, add the cooled ganache and beat for about 2 minutes, or until completely combined. Stop to scrape the sides and bottom of the bowl. Turn up the mixer speed to medium-high and beat for about 1 minute, or until the frosting lightens in color and thickens. You should have about 4 cups. (Use the frosting the day you make it, or cover and store in the refrigerator for up to 1 day, then bring to room temperature and paddle again for a few minutes until smooth before using.) Remove the cooled cakes from their pans. (Be sure they are completely cool. If they are even the slightest bit warm, the frosting will melt and you will have a mess.) Using a long, serrated knife, trim the top of each cake to level it (the layers will have rounded a bit in the oven; the trimmed scraps make great nibbles). Place one cake layer on a cake plate or cake pedestal (if you have a revolving cake stand, use it). Spoon about 1 cup of the frosting on top and use an offset spatula to spread it evenly to the edges. Carefully place the second cake layer, top-side down (so the even, sharp edges will be on the top of the finished cake), on top. Spoon about 1 cup of the frosting on top and spread it over the top and down the sides of the cake, smoothing the frosting as well as you can and covering the entire cake with a thin layer. This is the crumb coat that will keep any loose crumbs from migrating to the surface of the finished cake. Spoon a heaping cup of frosting on top of the cake, and spread it evenly across the top and down the sides. This is the finishing layer of frosting. If desired, spoon any remaining frosting into a pastry bag fitted with a small round or star tip and pipe a decorative line along the top and/or bottom edge of the cake. The cake can be stored in an airtight container at room temperature for up to 2 days.
