Vanilla Birthday Cake with Chocolate Buttercream Frosting is a light and fluffy classic, worthy of celebration.
Happy Birthday Superman Cooks! This week we celebrate our blog’s fourth birthday, and we are doing it in style, thanks to this Vanilla Birthday Cake, courtesy of Smitten Kitchen. We are huge fans of Deb Perelman’s site and her recipes, so it just made sense to rely on her expertise when it came to baking a classic cake.
It is hard to believe that four years have passed since we started our blog. We have come so far and learned so much. We honestly had no idea what we were doing when we started (which is sometimes the best way to start anything). I believed that Keith had a unique talent for cooking that people would be interested in, and I hoped that I could capture his art accurately with a camera. These beliefs still hold true today, as we continue this adventure together.
As we indulge in this gloriously fluffy and moist Vanilla Birthday Cake, topped with rich chocolate buttercream frosting (as only the best cakes should be), we are taking some time to reflect on our journey and to make plans for the future. Keith’s cooking and artistry continues to impress me on a daily basis. It inspires me to become a better photographer, to find new ways to communicate just how good this food really is.
We are truly grateful for the support we have received over the years: for our dedicated readers and followers; for the brands who have sponsored us; for every person who has made one of our recipes. Perhaps most of all, I am grateful to have discovered this passion in my life, and to share this incredible journey with my best friend.
