1-Line an 8″x8″ baking pan: with aluminum foil and spray with cooking spray to keep everything from sticking.

2-Prepare the brownie mix: as directed on the package and bake it according to the instructions, which typically takes about 20-30 minutes.

3-Allow the brownies to cool completely: which should take around 1.5 hours, so they hold their shape when you cut them.

4-Remove the brownies from the pan and cut them into 12 triangles: by making three rows and then cutting in alternating diagonals for that tree shape.

5-Unwrap the candy canes and cut them into 1.5-inch pieces: to serve as tree trunks, then press the sharp end into the bottom of each brownie triangle.

6-Spoon about half of the icing into a bowl and mix in 40-50 drops of green food coloring: until you get the shade you want.

7-Transfer the green icing to a sealable plastic bag: and snip off a small corner to make piping easier.

8-Starting at the top of each brownie triangle, pipe the icing in a zigzag pattern: going downward to look like tree branches.

9-Decorate with small round sprinkles: and add a small star sprinkle on top of each tree for a finishing touch.

10-Optionally, let the icing harden overnight in an airtight container: to keep everything fresh.
