Those bright orange silicone pans look and feel like toys. The traditionalist in me just cringes at the sight of them -- having baked for decades in sturdy, non-reactive Pyrex glass.

And, yeah, the bigger pan didn't work in all the ways you mentioned. The center was still raw and the edges were cement hard. The dogs enjoyed it all though. It didn't go to waste.

Peanut butter??? OMG!! The Weasel dips peanut butter out of the jar with his finger and eats it that way. He has his very own peanut butter jar for that, because I think that's disgusting. If he hears about peanut butter on banana bread, he'll turn into an Elvis-clone.
