Thirty Minute Yellow Cake Recipes

Steps:

• Preheat the oven to 350°F (180°C). Grease and line 2 9-inch (22 cm) round cake pans with parchment paper.
• In a large bowl, cream the butter and sugar with an electric hand mixer on medium speed until light and fluffy, 3-5 minutes, stopping to scrape down the sides of the bowl 2-3 times. Add eggs and the egg yolk, 1 at a time, beating for 30 seconds between each addition, or until just combined. Add the vanilla and beat until incorporated.
• In a medium bowl, whisk together the flour, baking powder, baking soda, and salt.
• Add ¼ of the dry ingredients to the batter and beat on medium speed for about 30 seconds, or until fully combined. Add ¼ of the buttermilk and mix for another 30 seconds, until well incorporated. Continue alternating with the remaining dry ingredients and buttermilk. Beat for 3 minutes more.
• Divide the batter evenly between the prepared pans. Bake the cake for 25-30 minutes, or until a toothpick inserted in the center comes out clean. Remove the cakes from the oven and let cool slightly, then remove from the pans and let cool completely on a wire rack.
• Make the frosting: In a large bowl, cream together the butter, cocoa powder, and salt with an electric hand mixer on medium speed until very thick and well incorporated, about 3 minutes. Scrape down the sides of the bowl.
• Turn the mixer speed to low and gradually alternate adding the powdered sugar and milk. As the sugar is incorporated, increase the speed of the mixer. Add the vanilla and beat until the frosting is smooth and fluffy, about 1 minute.The frosting will keep in an airtight container in the refrigerator for up to 1 week. Bring to room temperature before frosting the cake.
• Add a small dollop of frosting to a cake stand. Arrange four pieces of parchment paper around it. Place 1 cake round on the stand. Add a large dollop of frosting to the top of the first cake and spread evenly. Add the remaining cake layer on top and frost completely.
• Decorate the top with rainbow sprinkles, if desired.
• Remove the parchment paper. Slice and serve.
• Enjoy!

Steps:

• Place a rack in middle of oven; preheat to 350°. Butter two 9"-diameter cake pans and line each bottom with a parchment paper round; butter parchment. Using an electric mixer on low speed, mix 3 cups (345 g) cake flour, ¾ cup (150 g) granulated sugar, 1 Tbsp. baking powder, 1 tsp. baking soda, and 1 tsp. Diamond Crystal or ½ tsp. Morton kosher salt in a large bowl until combined, about 30 seconds.
• With the motor running, add ¾ cup (1½ sticks) unsalted butter, room temperature, cut into pieces, then increase speed to medium and beat until butter is in small pieces and mixture looks sandy, about 3 minutes.
• Turn off mixer and add 4 large eggs, room temperature, 2 large egg yolks, room temperature, 1½ cups buttermilk, room temperature, and 1 Tbsp. vanilla extract. Beat on medium-high speed until pale yellow and fluffy, about 1 minute (be careful not to overmix batter). Divide batter between prepared pans and smooth tops with an offset spatula.
• Bake cakes until tops are golden and spring back when gently pressed, 30-35 minutes. Transfer pans to a wire rack and let cakes cool in pans 15 minutes. Run a small knife or offset spatula around inside of pans to loosen cakes, then turn out onto rack. Remove parchment and let cakes cool completely, about 1 hour.
• While the cakes are cooling, sift 4 cups (440 g) powdered sugar and 1½ cups (126 g) unsweetened Dutch-process cocoa powder into a medium bowl. Using an electric mixer with clean beaters (or paddle) on medium speed, beat 1½ cups (3 sticks) unsalted butter, room temperature, and ¾ tsp. Diamond Crystal or ½ tsp. Morton kosher salt in a large bowl until creamy, about 4 minutes. Add half of dry ingredients and beat on low speed until incorporated. Add remaining dry ingredients and ¼ cup plus 2 Tbsp. buttermilk, room temperature, and beat until thoroughly combined. If frosting is too stiff, thin with more buttermilk (1-2 Tbsp.) until it reaches a spreadable consistency.
• Using a large serrated knife, slice domed tops from cakes. Place 1 layer on a large plate or cake stand and spread a thick layer of frosting on top with an offset spatula. Place second cake layer on top and generously frost top and sides of cake with remaining buttercream. Smooth sides and create decorative swoops and swirls on the top.
