Yellow Birthday Sheet Cake with Chocolate Frosting
If I could only eat one cake for the rest of my life, I would pick this homemade yellow cake with fudge frosting every single time. It's got all those nostalgic yellow birthday cake vibes without any of the fuss. Just bake in a 13- x 9-inch pan, let it cool, and frost. No fussy decorating needed. This is a from-scratch cake well worth the (minimal) effort.
