Be absolutely certain you spray the pan with PAM "for baking" (with flour) or Wilton baking spray. Sprays WITHOUT flour makes cones for some odd reason. Don't know why. Something in the chemisrty of it all. And any other greasing method makes for probs (butter, oil, etc.) This pan is made to take half a standard mix. Mix it, split it in half, then dump one half into the pan. The angled flange keeps it all in while you use a spatula to spread it into the half spheres. Be sure the half balls are filled completely. They SHOULD overflow a bit but not all over the oven. If they peek through or overflow a bit (into yummy little cups) you know you had the right amount of batter. If it overflows all over the place, the overflow blocks the convection & keeps the ball from baking up fully. Not sure why people have problems with it. I get completely round balls every time if I use the prescribed method. But I have deviated from the instructions and a number of things have happened (too flat, too dry, etc.) Hope this helps!
