With just a little extra effort a plain brownie can be made fancy enough for a holiday tray.
Use your favorite basic brownie recipe, or simplify like I did and use a brownie mix. I baked two 9 x 13-inch pans of brownies, then cut them into 2 x 3-inch pieces.
I used green Wilton candy melts, mini M & M's in red and green, and regular M & M's in yellow. I used a squeeze bottle to apply the candy melts.
On each brownie I applied a line shape to resemble a Christmas tree.
For each brownie, I used 3 red and 3 green mini M & M's on the tree and one yellow M & M on the top of the tree.
The candy melts dry quickly and hold the M & M's in place, so these brownies are also suitable for packaging.
