If you didn’t know already, I have an absolute obsession with cake. Coconut Cake, Ice Cream Cake, Polenta Cake . . . it doesn’t matter—I love it all! But sometimes nothing will do except rich, moist chocolate cake slathered with creamy, chocolate buttercream frosting, and this cake is exactly that. It’s at once homey, impressive, and deeply satisfying to eat. Adults and kids both love it because . . . chocolate. It’s the cake that strikes that nostalgic pang in my heart when I think of childhood birthday celebrations with balloons and streamers in primary colors. So go ahead: Make the time investment, bake this Chocolate Birthday Cake with Chocolate Frosting and eat your heart out, even if it’s only your un-birthday.
Notes: I used the cake batter to make 12 cupcakes, (for a birthday play-date with a few besties,) and a small 6-inch double layer cake to enjoy with the family. I’ve also included instructions for using the batter to make all cupcakes, a 9×13 cake, or an 8-inch 3-Layer cake: Don’t be scared off by all the text! I love the included recipe for Chocolate Buttercream Frosting because it stays beautifully shiny and creamy even as it sits out, and it’s not cloyingly sweet. If the frosting begins to curdle as you are beating it, switch to high speed and keep whipping it until it looks smooth again. Don’t worry, just keep whipping, and I promise it will come together. The cake is best at room temperature and will keep for 3 days without refrigeration . . . if it lasts that long!
