Salted Caramel Brownies

This was in a Food Network magazine.  They turned out pretty good - and rich!  I think Rachelle and Betty Ann could handle it, but normal palates, not so sure.  A couple changes I made: I used Paro instead of coffee granules since I didn't have coffee, and sprinkled coarse salt instead of flaked salt over top of the caramel since I didn't have flaked salt either.  (The salt and caramel on top is NECESSARY!  It's the finishing touch.)  These changes seem to have been okay 'cause they turned out good.  (Again, used the author's photo.)

1 c. butter
1 1/3 c. plus 1 c. semisweet chocolate chips, divided
3 oz. unsweetened chocolate
3 extra-large eggs
1 1/2 Tbsp instant coffee granules
1 1/2 Tbsp vanilla
1 c. plus 2 Tbsp sugar
1/2 c. plus 2 Tbsp flour, divided
1 1/2 tsp. baking powder
1/2 tsp. kosher salt
5-6 oz. good caramel sauce
2-3 tsp. flaked sea salt

1. Preheat oven to 350.  Butter and flour a 9x12x1 1/2 inch baking pan.
2. Melt the butter, 1 1/3 c. chocolate chips, and the unsweetened chocolate together in a medium bowl set over simmering water.  Allow to cool for 15 minutes.  In a large bowl, stir (do not beat) together the eggs, coffee, vanilla and sugar.  Stir the chocolate mixture into the egg mixture and allow to cool to room temperature.  (It is very important to allow the butter to cool before adding the chocolate chips, or the chips will melt and ruin the brownies.)
3. In a medium bowl, sift together 1/2 c. of the flour, the baking powder and salt and add to the chocolate mixture.  Toss the remaining 1 c. of chocolate chips with 2 Tbsp flour in a medium bowl and add them to the chocolate mixture.  Spread evenly in the prepared pan.
4. Bake for 35 minutes, until a toothpick comes out clean.  Don't overbake!
5. As soon as the brownies are out of the oven, place of the jar of caramel sauce without the lid in a microwave and heat just until it's pourable.  Stir until smooth.  Drizzle the caramel evenly over the hot brownies and sprinkle with the sea salt.  Cool completely and cut into bars.
