Why is it called Neiman Marcus cake?
The name has been passed around for decades through community cookbooks, church potlucks, and recipe cards. The exact origin is a little murky (it is one of those famous recipe-card folklore stories), but you will also see it called gooey butter cake bars or cream cheese cake bars. Whatever you call it, the formula is the same: cake mix crust plus cream cheese topping.
Is this the same as St. Louis gooey butter cake?
They are close cousins. Traditional St. Louis gooey butter cake is often made from scratch with a yeasted or cake-style base. Neiman Marcus cake uses cake mix for a quicker crust and bakes up as easy-to-slice bars.
Can I use a different cake mix flavor?
Yes. Yellow is the classic, but butter pecan is unreal, and spice cake is perfect in fall. If you go chocolate, expect a richer, brownie-adjacent vibe.
How do I know when it is done?
The edges should look set and lightly golden, and the center should still have a slight jiggle. If you bake until the middle is firm, you lose the whole gooey magic.
My top cracked. Did I mess it up?
Nope. Small cracks happen if the top sets a little faster. A dusting of powdered sugar covers all sins, and the texture is what matters.
Can this sit out at a party?
Because it is cream-cheese based, treat it like a cheesecake bar. For food safety, do not leave it out longer than about 2 hours. If it is a long hang, set out a smaller plate and refresh from the fridge.
