I use a regular box of brownies. Using the small scoop and the mini muffin pan 1 box of brownies usually makes 3 dozen brownies. Since the 2nd batch is only half of the pan you will need to fill the other unused spots with water. Anyway, I baked it at the same temp as on the box for 12-14 min. I just check it after 12 mins. and adjust the time accordingly.
