Preheat the oven to 350ºC (180ºF).
Grease the bottom of an 8-inch square pan, then line it with wax paper.
In a bowl, combine Maya’s Decadence Fudge Brownie Mix, water, vegetable oil and egg. Mix until well blended (you can do this by hand or with an electric mixer).
Wipe the cherries well with paper towels, then slice them in halves.
Add the cherries, nuts and chocolate chips to the mixture. Pour into prepared pan.
Bake in the preheated oven for 40-45 minutes or until toothpick inserted in the center comes out clean.
Let cool, then cut into squares.
