Old Fashioned Chocolate Layer Cake Americas Test Kitchen Recipe 385

Steps:

• Heat oven to 350*. Grease and flour 2 round cake pans. Combine chocolate, cocoa, & water in medium heatproof bowl; set bowl over saucepan with 1 inch simmering water and stir with spatula until chocolate is melted, about 2 minutes. Add ½ c. sugar to chocolate mixture and stir until thick and glossy, 1-2 minutes. Remove bowl from heat and set aside to cool. Whisk flour, baking soda, & salt in medium bowl. Combine buttermilk & vanilla in small bowl. In bowl of standing mixer fitted with whisk attachment, whisk eggs & yolks on medium-low speed until combined, about 10 seconds. Add remaining 1 ¼ c. sugar, increase speed to high, and whisk until fluffy & lightened in color, 2-3 minutes. Replace whisk with paddle attachment. Add cooled chocolate mixture to egg/sugar mixture and mix on medium speed until thoroughly incorporated, 30-45 seconds, pausing to scrape down sides of bowl with spatula as needed. Add softened butter 1 Tbsp. at a time, mixing about 10 seconds after each addition. Add about 1/3 of flour mixture followed by 1/2 of buttermilk mixture, mixing until incorporated after each addition (about 15 seconds). Repeat using half of remaining flour mixture & all of remaining buttermilk mixture (batter may appear separated). Scrape down sides of bowl and add remaining flour mixture; mix at medium-low speed until batter is thoroughly combined, about 15 seconds. Remove bowl from mixer & fold batter once or twice with spatula to incorporate any remaining flour. Divide batter evenly between prepared cake pans; smooth batter to edges of pan with spatula. Bake cakes until toothpick inserted into center comes out with a few crumbs attached, 25-30 minutes. Cool cakes in pans 15 minutes, then invert onto wire rack. Cool cakes to room temperature before frosting, 45-60 minutes. FROSTING: Melt chocolate in heatproof bowl set over saucepan containing 1 inch barely simmering water, stirring occasionally until smooth. Remove from heat & set aside. Meanwhile, heat butter in small saucepan over medium-low heat until melted. Increase heat to medium; add sugar, corn syrup, vanilla, & salt and stir with heatproof spatula until sugar is dissolved, 4-5 minutes. Add melted chocolate, butter mixture, & cream to clean bowl of standing mixer and stir to thoroughly combine. Place mixer bowl over ice bath & stir mixture constantly with spatula until frosting is thick & just beginning to harden against sides of bowl, 1-2 minutes (frosting should be 70*). Place bowl on standing mixer fitted with paddle attachment and beat on medium-high speed until frosting is light & fluffy, 1-2 minutes. Stir with spatula until completely smooth.

Steps:

• Break chocolate into pieces; place in small saucepan with 1/3 cup water. Stir constantly over low heat until chocolate has melted. Cool. (This can be successfully done in microwave. Go slow so as not to burn the chocolate.).
• Cream butter and sugar in large mixing bowl until very light and fluffy. Add eggs and vanilla; beat well. Blend in chocolate.
• Combine flour, baking soda and salt; add alternately with 1 cup water on low speed. Beat just until well-blended. Pour batter into well-greased and floured cake pans.
• Tip: outline a piece of waxed paper the size of the bottom of the cake pan and cut with sissors to size and place in bottom. No need to grease or butter pan.
• Bake at 350 degrees. Cake is done if toothpick inserted in center comes out clean. Cool 10 minutes. Remove from pans by inverting onto wire rack. If using waxed paper liner, remove and discard. Cool cake layers completely before frosting.
