Let Them Eat Toast

I need catharsis right now.  Or maybe just some sympathy.

I made this recipe for spiced pumpkin muffins with a streusel topping.  I highly recommend it, as it's been a pleasant part of my venture into soaking flour (you can read more about my dilemma here).  And it usually works great, like this:

Yesterday's nice, plump muffin.

Today, they looked like this:

I found walnuts at the bottoms of the muffins.  I think they got streuseled.

A few of them made it to the cooling rack, but we may be eating toast for breakfast.

I did do a couple things differently.  I was out of butter last night, so I soaked the flour only in kefir, not in the kefir/butter/honey combo.  But I've done that before and haven't had problems.  I also melted the butter shortly before adding it into the batter, so maybe I should have let it cool.  Not sure, but I do wish we had pigs!

I will, of course, try this recipe again since it's worked so well before and I like to compete against myself.  And I'd welcome any troubleshooting ideas!
