Vanilla And Chocolate Buttercream Food

CHOCOLATE SHEET CAKE WITH VANILLA BUTTERCREAM

Steps:

• Preheat oven to 350 degrees. Butter a 9-by-13-inch baking pan. Line bottom with parchment; butter parchment. Stir together boiling water, cocoa, and chocolate; let cool 10 minutes. Meanwhile, whisk together flour, baking powder, baking soda, and salt in another bowl.
• Beat butter with sugar on medium-high speed until fluffy, 2 to 3 minutes. Beat in eggs, one at a time, beating to combine after each addition and scraping down sides of bowl as needed. Beat in vanilla, then chocolate mixture. Reduce speed to low; beat in flour mixture in two batches, alternating with sour cream, until just combined. Scrape batter into prepared pan, smoothing top with an offset spatula.
• Bake until a tester inserted in center comes out with a few moist crumbs, 35 to 40 minutes (top will not spring back). Let cool in pan 10 minutes. Invert onto a wire rack and remove parchment; let cool completely. Cake can be made up to 1 day ahead and stored at room temperature, wrapped in plastic.
• Spread buttercream evenly over top and sides of cake. Sprinkle with chocolate curls. (Leftovers can be refrigerated, wrapped in plastic, up to 3 days; return to room temperature before serving.)

CHOCOLATE AMERICAN BUTTERCREAM

Steps:

• Combine the butter and cocoa powder in the bowl of a stand mixer fitted with a paddle attachment (or in a large bowl if using a handheld electric mixer). Mix on low speed until combined. Add the vanilla and salt. Continue to mix on low speed, adding the sugar a cup at a time and alternating with additions of the milk. Increase the speed to medium-high and mix until smooth. Use immediately, or refrigerate in an airtight container up to 3 days. Allow to come to room temperature and mix on medium-high until smooth.

VANILLA AND CHOCOLATE BUTTERCREAM

Steps:

• In a heatproof mixer bowl set over a pot of simmering water, whisk together sugar and egg whites until sugar is dissolved and mixture is very warm to the touch, about 5 minutes. Remove from heat. Beat on medium speed until completely cooled and stiff peaks have formed, about 10 minutes.
• With mixer on medium speed, add butter a few tablespoons at a time until completely combined. Add vanilla. Beat on low speed until smooth, about 5 minutes.
• Measure out 2 cups vanilla buttercream; set aside. Add chocolate to remaining buttercream; mix on low until combined.
• Divide reserved vanilla buttercream into thirds; tint one yellow and one pink. Add 1 to 2 tablespoons chocolate buttercream to the third to make a light brown for piping a contrasting border. Use immediately.
