Since we are still talking about muffins here is some info I hope
will be useful for you.
Choosing the Right Muffin Tin
Muffin pan sizes vary, and baking times vary with them: A mini
muffin will tyake 10 - 12 min; a standard-sized muffin, 15 - 18 min;
and a jumbo muffin, 22 - 25 min. Fill the muffin cups to any level
you wish. The standard is about 2/3 full, but you can fill them to
the rim for giant muffins. Batter for 12 standard muffins will make
48 miniature muffins, but only 6 - 8 jumbo muffins!
