1
Preheat oven to 350 degrees F. Grease a jelly roll pan (12x17) with butter.
-
2
You can dust the pan with flour, but I dont like how it makes the brownies white on the bottom so I use loose cocoa powder instead.
-
3
Melt together the 1 pound of butter, 8 oz of unsweetened chocolate, and one 12 oz bag of semisweet chocolate chips on top of a double boiler.
-
4
If you dont have a double boiler, just boil about 3 inches of water in a sauce pan and place a glass or metal bowl (with the butter and chocolate) on top of the pan with boiling water.
-
5
This will keep the chocolate from burning.
-
6
Once the butter and chocolate is melted, cool slightly.
-
7
Stir together eggs, espresso, vanilla and sugar.
-
8
Stir in the warm chocolate and cool to room temperature.
-
9
Stir together 1 cup of flour, baking powder, and salt.
-
10
Add to the cooled chocolate mixture.
-
11
Toss the remaining 12 oz bag of chocolate chips with the remaining 1/4 cup of flour.
-
12
Add to the chocolate batter and pour into the prepared pan.
-
13
Warm the caramel in a microwave for 20-30 seconds just so its soft and a little oozy.
-
14
Pour evenly over the brownie mixture.
-
15
Take a knife and cut the caramel into the brownies.
-
16
Do this by cutting vertically and horizontally through the entire pan.
-
17
It will create a nice swirl pattern that looks elegant once baked.
-
18
Bake for about 30 minutes, or until a toothpick comes out clean.
-
19
Do not overbake!
-
20
Cool thoroughly.

You can refrigerate if you like, but just wrapping with plastic wrap is sufficient.
