Begin by preparing your brownies in a square pan according to the package instructions. If you want to make them thicker, you can pour two batches of batter into a single pan and cook a bit longer. Be sure to spray your pan well so that the brownies will come out once cooled.
Once the brownies are done baking, set them aside to cool completely.
Turn the brownies over onto a sheet pan so that they come out smoothly.
Cut your brownies into tree shaped triangles.
Use the green decorator’s icing to create green garland in a zigzag pattern across the front of each brownie tree, beginning at the bottom and working toward the top..
Push the straight end of a mini candy cane into the bottom of each brownie tree with the curved end sticking out.
Place a star shaped cake sprinkle on the top of each brownie Christmas tree and decorate the trees with holiday colored candy pieces.
Finish your brownie Christmas trees by adding some holiday colored crystal sprinkles.
