In a mixer fitted with a whisk attachment, combine butter, powdered sugar, milk and vanilla.
Start on a slow speed. Once everything is combined, turn in on medium/high for 3-5 minutes or until it is light and fluffy.
Remove 1/3 of the icing and place in a separate bowl.
Add a few drops of green food coloring and place the bowl back on the mixer. Mix on low speed, and add more green food coloring if needed.
Cut a piece of parchment or wax paper 6" wide by 13" long.
Prepare a piping bag fitted with a small round tip. I used Wilton #3
Remove 3 -4 tablespoons of white icing and place it in the prepared piping bag.
Take out the krispy treats and place parchment in the center where your green section will be. If it is not sticking, use a little green icing on the corners to make it stick.
Use the remaining white icing to frost the sides of the krispy treat that is showing. This will be your stands.
Use a spoon to add sprinkles. Use the back of the spoon to press down the sprinkles into the icing.
Now you need to remove the extra sprinkles. Over a sink or baking sheet, place one hand on a 9" side of the pan and then other on the parchment paper in the middle of the treats. Carefully, using the hand that is on the 9" side, tip the pan up so the extra sprinkles all fall towards the other 9" side and eventually out of the pan.
Remove the parchment and ice the middle green. (See the tips in the post to make it super smooth)
Place the ruler on the sprinkles and mark the middle of the field and where your other lines will be. I did mine 2" apart.
Pipe your lines and numbers on the field. (See the tips in the post how to make your lines straight)
Take the almond and pipe one long horizontal line and three small vertical lines.
Place almond in the middle of the field.
