I made these and gave them out (and ate one or two, and stuck the end pieces in my freezer). First time I have gone to Caribou just for 2 shots of espresso.
I got 12-16 brownies out of a 9×13 pan (so these are big). And rich. And needs ice cream (or milk).
1 lb unsalted butter
20 oz semi-sweet chocolate (next time I would add in more dark)
1 cup flour
1 T baking powder
1 tsp salt
2 1/2 cups sugar
2 T vanilla
2 T espresso
6 oz semi-sweet chocolate chips
1 heaping cup chopped walnuts
350, 9×13 pan lined with foil, sprayed with pam
Melt the butter and 20 oz of chocolate. Whisk together dry ingredients. Beat eggs and sugar for about 5 minutes until light in color and frothy in texture. Add vanilla and espresso. Mix in melted chocolate. Fold in chips and nuts.
