What a busy baking week. Rigby celebrated her 14th birthday on Friday and she needed cookies for the school music department bake sale. A couple dozen cookies and a cake, should be easy, right? Sure. Friday morning loomed and I was out of bed making Rigby some cinnamon roll pancakes for breakfast before school. At the same time, I whipped up her favorite S'mores cupcakes for her to enjoy with dinner that night. The actual birthday cake was for Saturday when my parents came.
So pancakes are made, cupcakes are cooling, and Rigby is delivered to school. Now it's time to make my contribution to the bake sale the school music department was having on Saturday as well. Cookie are made and packaged up and now it's time to deliver the Caramel Pecan Rolls I made the day before. Then back home to make the cake. At her request, I made a Marble cake with chocolate frosting. Not just any frosting, but chocolate Swiss meringue butter cream. Swiss meringue butter cream is tricky to make to begin with, but add melted chocolate to an already delicate recipe.... Thankfully the frosting turned out and the cake was delicious as well. Over all Rigby's birthday was a success. Her big gift, a guitar.
Marble Cake
- 3 cups sifted all-purpose flour, plus more for dusting
- 1 tablespoon baking powder
- 3/4 teaspoon salt
- 1 cup milk, at room temperature
- 2 teaspoons pure vanilla extract
- 1 1/2 sticks unsalted butter, softened
- 2 cups granulated sugar
- 4 large eggs, at room temperature
- 4 ounces bittersweet chocolate, melted and cooled
Preheat the oven to 350°. Butter two 9-by-2-inch round cake pans and line with parchment paper; butter and dust with flour. In a bowl, mix the 3 cups of flour, baking powder, and salt. In a cup, mix the milk with the vanilla.
Beat the butter at medium speed until light and creamy. Add the sugar and beat until fluffy. Beat in the eggs, one at a time, scraping down the bowl. Beat in the dry ingredients in 3 batches, alternating with the milk mixture and scraping down the bowl.
Mix 2 cups of the batter with the melted and cooled bittersweet chocolate. Scrape the remaining batter into the pans. Dollop the chocolate batter over the batter in the pans and swirl with a knife. Bake in the lower third of the oven for about 35 minutes, until springy. Let cool for 15 minutes, then run a knife around the edges and invert onto a rack. Peel off the paper, turn the cakes upright and cool completely.
Chocolate Swiss Meringue Butter Cream
4 large egg whites
1 1/4 cups sugar
1 cup (2 sticks) unsalted butter, cut into tablespoons, room temperature
1 teaspoon vanilla extract
1/2 cup melted and cooled semisweet or bittersweet chocolate
3 tablespoons unsweetened cocoa powder
Put egg whites and sugar into the top of a double boiler over a pan of simmering water. Whisking constantly, cook until sugar has dissolved and mixture is warm (about 160 degrees). The egg whites will start to foam and grow as you heat them.
Pour heated egg whites into the bowl of an electric mixer fitted with the whisk attachment. Beat egg white mixture on high speed until it forms stiff (but not dry) peaks. Continue beating until fluffy and cooled, about 7 minutes.
Switch to the paddle attachment. With mixer on medium-low, add butter two tablespoons at a time, beating well after each addition. Increase speed to medium-high; continue beating until frosting appears thick, about 3 minutes.
Reduce speed to low; add vanilla extract, chocolate and cocoa and continue beating 2 minutes to eliminate air bubbles.
