Let the cake sit in the pan for exactly 10 to 15 minutes. That’s it. This is the "setting" phase. The steam inside the cake redistributes, and the structure firms up.
Why ten minutes? Because less than five, and the cake is lava. More than twenty, and the condensation starts making the bottom soggy. Nobody likes a soggy bottom.
What Happens Inside That Hot Pan?
When the cake bakes, the edges cook first. The center is still gooey and full of trapped steam. If you flip it immediately, the center collapses like a tiny, sugary earthquake.
During those ten minutes, the steam escapes gradually. The cake pulls slightly away from the pan walls. It’s like the cake is taking a deep breath and saying, “Okay, I’m ready for my close-up.”
Fun fact: A cake’s internal temperature is still rising for about two minutes after you pull it out of the oven. It’s called “carryover cooking.” Your cake is still baking on your counter!
