In a large mixing bowl, cream together butter and sugar until light and fluffy.
Add the egg, molasses, and vinegar and mix until roughly combined.
Add flour, baking soda, ground ginger, cinnamon powder, cloves powder, nutmeg powder and mix until combined. Use your hands, if necessary to bring the mixture together into a ball of dough.
Chill dough in the fridge for 1 hour.
Divide the dough into 2 portions and work with one portion at a time. It's just easier this way. I keep the unused portion in the fridge until I am ready to use it.
Roll dough between 2 sheets of parchment paper. Mine were about ½ inch thick. If you make them ¼ inch thick, they are crispier.
Use a tree shaped cookie cutter to make cut outs.
Remove excess dough around the shapes.
Transfer sheet of parchment paper with the cut outs to a baking tray.
Bake at 350 degrees F for 10-12 minutes or until edges are firm and center is slightly soft but not jiggly.
Remove from oven and let them cool completely in the tray.
Then, gently remove cookies from parchment paper.
Filling a piping bag with melted chocolate and cut a small slit at the pointy end.
Drizzle chocolate on top of each cookie.
Stick m&m candies before the chocolate sets. Enjoy!
