Here’s a tip a friend recommended:
Before putting your cake in the oven, wrap a thick, wet towel around the filled cake pan. Pin the edges of the towel closed over the top. This moist heat will help your cake rise more evenly.
You’ll want to keep an eye on your oven when you do this, just in case! If your towel is wet, it shouldn’t pose a fire hazard. But it would certainly put a damper on the whole cake-eating experience if you had to invite the fire department to have a slice, too!
