You may have to pick the green candies out of a regular bag of candy-coated chocolates.
Preheat the oven to 200 F. Line a cookie sheet with wax paper.
Place the pretzels on the cookie sheet. Place a chocolate morsel on each pretzel. Place the cookie sheet in the oven. Allow chocolates to melt until they become soft. Remove the cookie sheet from the oven and promptly press the chocolate flat on the pretzel. Add three green candies to the pretzels to form a three-leaf clover. Allow the pretzels to cool completely.
In a mixing bowl, add the sugar, butter, and milk. Add food coloring until you achieve the desired color. The consistency of the mixture should feel like moldable clay. You can keep adding sugar until you achieve desired consistency. Pinch off a piece of the icing and roll the stem of the clover with your fingers, and then add to the pretzel. Enjoy!
