Here's one I LOVE from Nigella Lawson's cookbooks. It has 3 sticks, plus 2 tablespoons of butter. Need I say more? I make these for almost every birthday, family gathering, etc. If I don't have white chocolate chips on hand, I just use extra chocolate chips, like I did here.
The only way these could possibly get any better would be to top them with a scoop of vanilla ice cream and some caramel sauce.

I don't have a 9x11 pan like she uses, so I use either a 9x13 (bake for about 30 minutes), or an odd 8x10 (bake for 50 minutes).
