Pour the caramel brownie batter into the dish and bake for 35-45 minutes. DO NOT OVER BAKE. Check at 35 minutes with a toothpick. The moment the toothpick comes out mostly clean, remove from the oven. The brownies continue to cook a little as they're cooling, but you don’t want them to be overcooked.
Allow the brownies to cool completely. Cut into 12 large, 18 medium, or 24 small squares. Clean the knife with a paper towel in between cuts to insure the edges are as smooth as possible. Carefully remove the homemade brownies with a spatula.
