1 guirardelli box of brownie mix, 1/3 cup all-purpose flour, 1/4 cup vegetable oil, 2 large eggs, 1/2 tsp salt
Fold in the chocolate chunks then using a small cookie scooper (2 tablespoon scoop) scoop out the cookie dough, and place it on the cookie sheet making sure to leave enough space between each cookie because they will spread.
4 oz chocolate chunks
Bake for 9-10 minutes, or until the edges are set and the centers are slightly puffed. The cookies should still be soft in the center.
Remove the baking sheet from the oven and let the cookies cool on the sheet for a few minutes. They will firm up as they cool.
Transfer the cookies to a wire rack to cool completely before serving.
