I happened to catch "Best Thing I Ever Ate" on the Food Network the other night. The food judge, Alex, called out a brownie from a Long Island bakery named "Baked". It looked SO teriffic... oooey, semi-liquidy flor de sel caramel oozing out of the middle, so luscious looking. So I went hunting via google, and found something similar. No, it doesn't have the ooey caramel center, but it IS the BAKED bakery's brownie recipe and can be easily adapted to add the caramel center, though I wanted to just test out the brownie recipe first.
I can't tell you how good a brownie it is! I'm pickey and finikey when it comes to what I like. I've tried many, many brownie recipes over my half-century or so of brownie-eating. These are by far the best I've ever had. Now, to be sure... I used some good Valhrona chocolate, 'cause I only made a half-batch and it only needed 5.5 oz and I happened to have some in the house. But I used regular supermarket butter, a mix of Gold Medal & KA a/p flour, my normal Nielsen-Massey vanilla that I use all the tiime, 1 Tbls Valhrona cocoa, espress powder, the mix of brown & white sugars the recipe calls for, normal super-market eggs and nothing else special. I think these brownies would turn out great with any good chocolate. They're rich and they're fudgy without being under-baked.
I've also found a recipe for a BAKED's Flor de Sel caramel - but a sauce (it's part of BAKED's Sweet & Salty cake that I also can't wait to try). I'm gonna try it and see if it looks like what's in the brownies shown on the tv show and if so, I'll give that a try. It's gonna take something like par-baking half the brownies, adding the caramel, then adding the rest of the brownie batter and finishing baking. I'll let you know how they turn out!
Anyway... you can find the brownie recipe here if you want to give it a try
