This cake is a super moist and delicious chocolate sheet cake that is made in one bowl. It's fuss free and so quick to put together. And the chocolate yogurt fudge frosting is a dream! You can easily serve 16-20 people with this cake so it's a great recipe to make for a crowd. Here are the links to my 1-min TikTok and Instagram video tutorial.
