• Whisk the cake flour, baking powder, baking soda, and salt together in a large bowl. Set aside.
• Using a handheld or stand mixer fitted with a paddle attachment, beat the butter and sugar together on high speed for 3 full minutes.

• Add 1/2 of the cake flour mixture/dry ingredients and 1/2 of the milk and beat on low speed until combined. Add the remaining dry ingredients and milk and beat on low speed until combined. Do not overmix this batter. The batter will be smooth, velvety, and slightly thick. You may need to whisk it all by hand to make sure there are no lumps at the bottom of the bowl.
• Spread the cake batter into the prepared pan. Smooth it out into a thin, even layer. For a 12×17 inch sheet cake, bake for 20-22 minutes or until the top is lightly browned and a toothpick inserted in the center comes out clean. For a 9×13 inch sheet cake, bake for 36-40 minutes or until the top is lightly browned and a toothpick inserted in the center comes out clean. With either size, make sure you rotate the cake pan once or twice during bake time.
• Remove from the oven and allow the cake to cool in the pan placed on a wire rack. As the cake cools, make the frosting.
• Using a handheld or stand mixer fitted with a paddle attachment, beat the butter on high speed until pale, smooth, and creamy, about 2 minutes. Using a fine mesh strainer or sieve, sift the confectioners' sugar and cocoa together. Add the sugar/cocoa mixture to the butter, then beat on low speed for 20 seconds. Stop the mixer, then add the milk, corn syrup, vanilla, and salt. Beat on medium-high speed for 2 minutes. If the frosting is too thick, beat in an extra splash of milk.
