Preheat oven to 350F/177C. Grease a 12-hole square pan. Set aside.
In a bowl, stir butter, eggs, Fudge Brownie Mix until well blended.
Fold in ½ cup of chocolate chips. Divide the batter in three pans.
Repeat steps 2 and 3 with the Butterscotch Brownie Mix.
Scoop a chocolate brownie mixture into the holes and then scoop the butterscotch mixture beside the chocolate brownie dough to make brookies.
Bake brownies for 20-25 minutes or until baked. Loosen from the pans and let the brownies cool.
