What is Gooey Butter Cake?

Gooey butter cake is a yummy dessert that originated in St Louis, MO around the 1930s.

There’s a cake layer on the bottom and a soft cream cheese layer on top that earns it the gooey name. So you get the effect of a soft crust topped with a cheesecake like topping.

I wasn’t sure about warm ooey gooey cake, but it was pretty darn good. So feel free to warm a piece to try… or use this as a license to not let your cake cool completely before you dig in. I’m not judging!
