For those of you who want to try the cake recipe I made for my birthday, here’s the site: https://pinchofyum.com/gooey-chocolate-caramel-cake
The site also has much better pictures than mine! Just looking at them just now made me crave the cake; fortunately I still have a few pieces left.
BTW, the only change I made to the recipe was to add some coarse salt to the top of the caramel. So it’s actually Gooey Chocolate Salted Caramel Cake!
