How long do you let it cool in the pan before removing it? With a moist cake, this is crucial! Thanks!
So funny you asked. I just baked this cake this morning. I was in a hurry, so I heavily sprayed the pan with Bakers Spray, and then spread it all over e inside with a paper towel so i made sure it was well coated. Then i sprinkled a lot of cocoa powder on the inside. I let it cool for less than 5 minutes-- I didn't want to be late for yoga class!-- and when I turned it onto the cooling rack, it plopped right out. I think the heavy pre-treatment was key.
i just made a similar recipe and left it in the pan for 30 minutes, as per the recipe instructions. I f you're not in a rush I'd err on the side of leaving it in there between 15 and 30 so it doesn't fall apart.
I'm with ChefOno, basically till it's just cool enough to get out of the pan. In addition, if you want to keep it moist, one trick is to let it cool on the rack for another 10-15 minutes and then wrap tightly in plastic wrap to chill (or freeze). Allowing your cake to cool this way improves texture and crumb significantly.
