Preheat oven to 350 degrees
In a large mixing bowl, combine the brownie mix and the flour
Mix in the eggs, oil and mint extract until combined
Using an ice cream scoop, scoop some of the batter onto the cookie sheet. You should be able to fit on about 12 cookies
Bake in the oven for 8-12 minutes
While the cookies are baking, unwrap your dove chocolate and set aside
Once the cookies are baked, let them sit on the counter to cool for about a minute
Place a dove chocolate onto the center of the cookie and lightly push down
Allow the cookies to cool for about 30 minutes. The chocolate will start to melt and cover almost the top of the cookie
While the chocolate is still melted, add 3 green M&M's onto the top of the cookie to create a shamrock
Add the a small amount of the green icing into the piping bag and cut the tip off
Pipe a stem under the M&M's
Allow cookies to cool for another 30 minutes before enjoying with a large glass of milk or a large cup of coffee!
