What is Gooey Butter Cake you ask? It is a super-sweet, rich, St.Louis original treat! I have made this recipe hundreds of times to rave reviews. My fiances co workers even go as far as to trade work for Gooey Butter Cake! But what's someone from out-of-town, or in my case, relocated Las Vegas, to do? Follow This Recipe! It's super easy...anyone can make it! ENJOY!
