My darling daughter very recently turned two. The Nuni is growing up — getting more independent, more vocal, more affectionate, more skilled. She chatters and tumbles and climbs her way through life. The Nuni was quite pleased to have a birthday, especially one that involved bubbles and balloons and cake, and has been known to sing a rousing chorus of “HAPU CAKEY NUNI!” six or seven times a day.
I, on the other hand, now have to live with a two year old, which means that my life is now full of more drama than the Real Housewives of New York. Either a tutu is too short or a spoon is too shiny or I am not promptly answering some silent or intelligible command and then you better WATCH OUT. On the other hand, there are kisses and pretend play (“I cooking Mommy!” being my favorite, natch) and a constant source of entertainment. So it all balances out, I suppose.
But I digress. Birthdays are the name of the game, and if you are me, that means birthday cake, and homemade birthday cake at that. I asked the Nuni several times before her birthday party what kind of cake she would like — Strawberry cake? (She loves strawberries) Orange cake? (My personal favorite) Gateau d’Opera? Being two, she would only answer me with the cryptic “Green Cake”. Now I could have taken this in any one of a number of directions — all organic, local and sustainable ingredients? Chock full of spinach and zucchini? But I decided to treat this as simply a color request. I thought I’d stay simple, not only for my general sanity this year but also because I hope to establish a precedent of a rather basic cake that would become the standard, de rigeur birthday cake. (I shudder to think what I put my own mother through. My standard request throughout my childhood was something I called “purgatory cake” – angels food on top, devil’s food on the bottom, with a chocolate mousse filling and seven minute frosting. Can you imagine the number of bowls?)
I decided on chocolate cake, because, well, it’s chocolate cake, and no further explanation should be necessary. I scoured my cookbook library, websites and back issues of cooking magazines to find the perfect chocolate cake recipe, and I think this may just be it. It’s moist but structured enough to stand up to layering and frosting, chocolatey without being bitter or too intense, and relatively simple to mix (although it does take two bowls). It would take to a good chocolate frosting, but to accede to my daughter’s request for a “geen” cake, I went with a white frosting and green food coloring — cream cheese frosting because I like it better than buttercream, and white chocolate for richness and pizzazz. Finally, I dug out my old cake decorating chops and decorated it with chocolate plastic, in no small part because I can’t pipe frosting to save my life.
To make the cake, I adapted a recipe from Cook’s Illustrated — I changed the original to use ingredients I usually have in my kitchen and to up the chocolate factor. It has an unorthodox mixing method — instead of the typical “cream butter and sugar, add eggs, then alternate flour and liquids” you begin this cake by making a “pudding” in a bowl over warm water of cocoa, sugar, semisweet chocolate and water (water adds moisture without diluting the flavor the way milk would). Then, while this is cooling, you beat eggs and yolks with sugar until fluffy, then add the chocolate mixture, and only then do you add butter. Finally, add the liquid (in this case, buttermilk) and dry ingredients in alternating batches. Bake them in round cake pans with straight sides — this is important! Many cake pans have flaring sides, which makes them stack easily for storing, but makes the resulting cakes much harder to stack and frost).
The frosting comes together easily — just be gentle when you’re melting the white chocolate, as it has a tendency to seize. I usually melt chocolate in the microwave, but white chocolate is just fussy enough that it’s worth using the double boiler (or bowl over pan of simmering water.) To assemble the cake, spread a bit of frosting and jam on one cake layer, then stack them (and check before you start frosting to make sure they’re straight). Whenever you want a smooth frosting, or when you’re frosting a dark cake with light frosting, it’s always a good idea to use a crumb coat, which is a thinnish 1st coat of frosting that catches the crumbs and keeps them in place. You chill the cake with the crumb coat before applying the real coat of frosting, which should be smooth and blemish free. At least theoretically. Some cakes may need two crumb coats, and this is probably one, as if you look closely at the picture of the finished cake you can see a few flecks of dark chocolate in the frosting. However, I’m serving this as a birthday cake to friends and family, none of whom a) notice or b) care, plus perfection does NOT run in my blood, so I think I can live.
Chocolate plastic is a neat accessory to cake decorating — it tastes fantastic and doesn’t require any specialty ingredients — just chocolate and corn syrup. To make it, you melt chocolate and cause it to seize by adding corn syrup, then knead it until it’s smooth. If you’re a sculptor you can use it to mold into flowers or other shapes, or you can roll it out (on a surface dusted with powdered sugar or cornstarch), cut it into shapes with cookie cutters, and affix those shapes to your cake. It has a bonus of tasting pretty darn good if you use decent chocolate, unlike many things you can use to decorate cakes. I used gel food coloring to color both the frosting and the chocolate plastic, and used two sizes of round cookie cutters to cut shapes in the plastic.
I consider baking a homemade birthday cake to be a sacred duty. I want to lavish my girl with love and attention and celebration to mark her birthday, and to celebrate the day I became a mother. And if the milestones bring drama with delight, well, at least I can hole up with leftover chocolate cake.
- ½ c. Dutch processed cocoa, divided (Dutch processed cocoa is a lovely dark brown color, and reacts differently than standard Hershey's). You can buy it in most stores, or order from Penzey's.
- 4 oz. semisweet chocolate (chocolate chips will work in a pinch)
- 2 c. sugar, divided
- ½ c. hot water
- 4 large eggs
- 2 large egg yolks
- 2 tsp vanilla extract
- 12 T salted butter (1½ sticks), very soft
- 1½ cups + 2 T unbleached all-purpose flour (8¾ ounces)
- 1½ teaspoons baking soda
- 1 tsp table salt
- 1 cup buttermilk
- Baker's Joy, or extra butter and flour for preparing pans
- 1 8 oz. jar tart jam - apricot, raspberry or plum preferred
- White chocolate cream cheese frosting
- Preheat oven to 350 degrees, prepare 2 9" cake pans by spraying with baker's joy or buttering and then flouring.
- Combine chocolate, ¼ c. cocoa powder, and hot water in a heatproof bowl, set it over ; set bowl over saucepan containing 1 inch of simmering water and stir until the chocolate is melted. Add ¾ cup sugar to chocolate mixture and stir until thick and glossy, 1 to 2 minutes. Remove bowl from heat and set aside to cool.
- In a standing mixer with a balloon whisk attachment, whisk the eggs and yolks until combined, then add remaining 1¼ c. sugar, increase the speed to high, and beat until fluffy and pale yellow. Add the cooled chocolate mixture and vanilla and mix until thoroughly incorporated, then, while mixer is running, add soft butter 1 T at a time and mix until thoroughly incorporated.
- Combine the flour, soda, remaining ¼ c. cocoa and salt. Add about ⅓ of the flour mixture to the mixer, followed by half of the buttermilk mixture, mixing until combined after each addition, and repeat until flour and buttermilk are thoroughly incorporated. Divide batter evenly between prepared cake pans; smooth batter to edges of pan with spatula.
- Bake cakes until a skewer inserted into center comes out with a few crumbs attached, 25 to 30 minutes. Cool cakes in pans 15 minutes, then invert onto wire rack. Cool cakes to room temperature before frosting, 45 to 60 minutes, or make the cakes a day or two ahead and freeze the layers, wrapped in plastic wrap and aluminum foil, then frost the frozen layers.
- Place dab of frosting on cake platter to hold cake in place, Place bottom layer of cake on center of platter. Spread a thin layer of frosting on top of cake, followed by jam. Center 2nd layer of cake atop the first. Spread a thin layer of frosting on the cake, starting with the sides and then moving to the top. An angled spatula is your friend here, and a turntable is even better. Get the frosting as smooth as possible, but it's OK if it's not entirely opaque. Chill until firm. When the crumb coat has chilled, coat the remainder of the cake in frosting, starting with the sides and then smoothing the top. Get as smooth as possible, then chill until serving.
- Optional: decorate with chocolate plastic cut outs.
- 1 lb white chocolate, finely chopped (make sure to use real white chocolate here, that contains cocoa butter in the ingredients, and ideally one that contains over 25% cocoa butter, such as Callebaut or El Rey)
- 18 oz. cream cheese, at room temperature
- 8 oz. unsalted butter
- Melt white chocolate in a double boiler, and cool. Beat cream cheese and butter together until fluffy, add white chocolate and beat until smooth. Chill before using.
- 16 oz. white chocolate
- ½ c. corn syrup
- Melt white chocolate in a double boiler. When the chocolate has melted, add corn syrup, and stir. Mixture will seize, but keep stirring, and then knead, until the mixture is smooth and pliable. Set aside at room temperature for at least 1 hour prior to use.
what a really pretty cake, happy birthday to your little one 🙂
Now that is one impressive cake! I might need an in-person demonstration of the chocolate plastic. That sounds like something that would come in handy.
WOW. Looks fabulous!! So so impressed. Happy, happy birthday to the Nuni!! We celebrated my daughter’s first birthday yesterday with vanilla cupcakes and chocolate buttercream frosting. Hopefully, the Nuni wasn’t as messy as she was!
It’s like one big birthday party over at your house. Let me guess, no BD cake for you? I bake one cake for the hubs BD on the 3rd and it doubles as mine. How much cake does a family of 3 need anyway? Yours (Nuni’s) looks beautiful.
Wonderful job! For my baby’s 2nd birthday I made him an ice cream cake. I was lucky that he didn’t have any opinions about it and I could just make what I wanted (although he does love ice cream.) I think I need a few cake decorating lessons from you. It’s not my strong point.
Thanks for sharing, this looks amazing/delicious.
This looks beautiful! I have a certain 2yo b’day coming up and think I’ll make something like this!
“until the mixture is smooth and pliable. Set aside at room temperature for at least 1 hour prior to use.”
Kate – do you rest it prior to shaping it, or after shaping it, prior to putting it on the cake?
