Moms Know Best
Okay, Nic. Your mama wasn’t exactly wrong. True, any cake can give you a stomach ache if you eat too much, but all traditional cakes must be cooled before icing, or the icing slides off and melts. Still, this only tends to take about… 30 minutes, so the “next day” thing is ridiculous.
However, warm cakes with ooey-gooey chocolate are so delicious you can’t help yourself. I should know, as I made four lava cakes for the family one day and accidentally ate them all before anyone else got home. It’s a known phenomenon your mom was probably trying to help you avoid.
