The following recipe comes off of Pinterest as well. You may see this often. I feel it is my duty to try out some of these recipes and report back. Its pretty good and it really does taste like a brownie. Its a nice mixture of cake like and fudge like as well.
Brownie Cookies – Serves 20
Whisk together brownie mix, flour and sugar. Using a wooden spoon, stir in eggs one at a time, followed by butter and 2 TB water. If the batter appears like there is too much flour, add 1 more TB of water. The batter should be very thick!
Fold in chocolate chunks. Cover and refrigerate 2 hours.
Preheat oven to 350 degrees. Grease a cookie sheet and drop heaping teaspoons of dough on cookie sheet. You want thick cookies here to get the brownie feel. Press down slightly, but don’t flatten. Bake for 10 minutes. Remove from oven and allow to cool for 2 min before transferring to a wire rack.
