RECIPE BIRTHDAY CAKES RECIPES

Steps:

• Place a rack in center of oven; preheat to 325°. Using your fingertips, grease bottom and sides of a 9" round cake pan with vegetable oil. Line bottom of pan with parchment paper, smoothing to eliminate air bubbles. (It may sound fancy, but making a parchment circle is easy! Place pan on a piece of parchment, trace circumference with a pencil, then cut it out.)
• Whisk 1⅓ cups all-purpose flour, 1¼ cups granulated sugar, 1¾ tsp. baking powder, ¼ tsp. baking soda, and 1¼ tsp. kosher salt in a large bowl. Sift ½ cup cocoa powder into bowl, then whisk to combine. (You can stop here and package these dry ingredients in an airtight container to create a sort of DIY cake mix if you want!)
• Whisk 2 large eggs, ¾ cup vegetable oil, and 1 tsp. vanilla extract in a medium bowl until well combined and creamy, about 30 seconds. Using a spatula, mix egg mixture into dry ingredients until fully incorporated. It will be thick and pasty, that’s okay!
• Warm 1 cup milk in a small saucepan over medium heat until it comes to just a bare simmer—make sure it doesn’t come to a boil. Whisk warmed milk into batter until lump-free and just combined; do not overmix.
• Immediately transfer batter to prepared pan. Tap pan a few times on work surface to encourage some of the bubbles to escape.
• Bake cake, turning pan halfway through, until a cake tester (or toothpick!) inserted into the center of cake comes out clean, 40–50 minutes. Transfer to a wire rack and let cake cool in pan.
• Meanwhile, make the frosting: Fill a medium pot with 1" water and bring to a bare simmer over medium heat. Combine 4 oz. chocolate chips and ½ cup heavy cream in a heatproof medium bowl, place over saucepan, and reduce heat to low (make sure bottom of bowl is not touching water). Stir occasionally with a spatula until chocolate is melted and mixture is homogeneous and thick. Chill ganache until cool to the touch, about 25 minutes (you can mix with a spatula to encourage cooling). Alternately, mix chocolate and cream in a microwave-safe bowl and microwave in 10-second bursts until melted.
• Using an electric mixer on medium-high speed, whisk 4 oz. (room temperature!) cream cheese, ¼ cup powdered sugar, and remaining ¾ tsp. vanilla extract and ¼ tsp. kosher salt in a large bowl until very smooth and no lumps remain. Beat in cooled chocolate ganache on medium speed, scraping down sides of bowl as needed, until frosting just holds its peak and is well combined and a little thicker, about 1 minute. You don’t want to overbeat because the frosting can become too stiff.
• Run a butter knife around edges of pan. Invert cooled cake onto a plate and peel off parchment. Invert again onto a platter.
• Top cake with frosting, spreading evenly across the surface. Make some decorative swooshes with a spoon, if desired. Slice and serve.

Steps:

• Preheat the oven to 350 degrees F. Butter and flour a 12 by 18 by 1 1/2-inch sheet pan.
• To make the cake, cream the butter and sugar on medium-high speed in the bowl of an electric mixer fitted with a paddle attachment until light and fluffy, about 5 minutes. On medium speed, add the eggs, 2 at a time, then the sour cream, vanilla, and lemon zest, scraping down the bowl as needed. Mix well. Sift together the flour, cornstarch, salt, and baking soda. With the mixer on low speed, slowly add the flour mixture to the butter mixture and stir just until smooth. Finish mixing by hand to be sure the batter is well mixed. Pour evenly into the pan, smooth the top with a spatula, and bake in the center of the oven for 25 to 30 minutes, or until a toothpick comes out clean. Cool in the pan to room temperature.
• For the frosting, place the chocolate chips and heavy cream in a bowl set over a pot of simmering water, stirring occasionally, until the chips are completely melted. Off the heat, add the corn syrup and vanilla and allow the chocolate mixture to cool to room temperature. In the bowl of an electric mixer fitted with the whisk attachment, whisk the chocolate mixture and softened butter on medium speed for a few minutes, until it's thickened.
• Spread the frosting evenly on the cake. Have the children decorate the cake with chocolate candies.
