Make the brownies. Mix the brownies up according to the package instructions. Pour the brownie mix into a greased pan and top with half of your candy. The candy tends to sink as the brownies cook so I save the other half of the candy until the last 5 minutes of baking.
Bake. Bake the brownies according to the instructions on the back of the package. 5 minutes before the brownies are finished baking pull the brownies out of the oven and add the rest of the candy to the top of the brownies, pressing it down into the brownies lightly. Finish baking.
