Culinary Foreshadowing

I mentioned in my last ramble that we are having overnight guests twice in the coming week, and that I would be spending my week stressing over the food. This evening I wanted to get a little jump on the dessert, so I baked, or rather, tried to bake some blond brownies, the "best ever", guaranteed-not-to-fail recipe.  Uh huh.  Right.  I took them out of the oven after 25 minutes, just like the directions said, because they were pulling away from the edge of the pan AND they passed the toothpick test.  Forward about 1/2 hour.  The kids have gone to bed, and I am going to sneak one, just a little corner piece. No!  It's like batter inside!! So I heat up the oven again, and stick the pan back in. Can you do that?  Will it work?  Apparently not. Twenty minutes later they are still goo inside, but I have decided to go to bed instead of having a baking marathon tonight.  I do hope this is not a portent of things to come....
