The last two camps this month benefited from this recipe, right off the back of Heath Bits o’ Brickle Toffee Bits. They’re a challenge to get out of the pan (even though the recipe says to spread the toffee mixture to within 1/4″ of the edges, it spreads all the way, anyway, and fuses there!), and I recommend cutting them into 48 pieces instead of 36 — really rich, and you know you’re going to have two anyway!
Yesterday when I opened the back door after we returned home from errands and lunch out, I could hear something that sounded like perhaps the furnace had thrown a bearing. (I don’t know what that means, exactly, but it was a loud and frightening roaring!) It wasn’t the furnace, it was my main computer, at the other end of the house, sounding like a semi was idling in the room. I bumped it when I was preparing to clean the wood floor in the office and because I hadn’t turned it off before I started moving things around, something really, really bad has happened. I can work, but the noise is annoying and clearly a sign of trouble sooner or, hopefully, later. If I had the right tool I could remove the back panel to see what’s happening (I already blew a disturbing amount of dust out of the tower), but I’m pretty sure it would be like opening the hood of the car: hands on hips + furrowed brows = get out credit card.
In the meantime, I’ll have another cookie to ease the pain.

Oh no! I hope you have solved your computer problem. My DH has spent the last 2 hours trying to revive an electrical outlet that quit working before we left on vacation. Once the new one was installed and tested, I went to vacuum up the mess using a different outlet and they both stopped working. A call has been placed to my electrician friend.
As for your bars, I’ve seen Giada or Ina use foil to line the pan leaving over-hang on all 4 sides of the pan. Then, just lift the whole thing out and cut.
