Watermelon Sugar Cookies

Watermelon reminds everyone of summer, so I thought a watermelon sugar cookie would be a great treat to add to a summer picnic.
This recipe should yield two dozen cookies.
Ingredients:
Flax egg- 2 tbsps ground flax meal, 6 tbsp water
1 cup Nondairy butter (softened)
1 cup Cane sugar
1 tsp Vanilla extract
2 2/3 cups Unbleached all-purpose flour
2 tsp Baking Soda
1 tsp Salt
1 1/2 tbsp Almond milk
Frosting:
2 1/2 cups Powdered sugar
1-3 tbsp water (for consistency)
1/2 cup Mini chocolate chips(Enjoy Life brand is allergy and vegan
friendly)
Red and green food coloring
Directions:
In a small mixing bowl, whisk flour, baking soda, and salt
Use a hand or stand mixer on medium speed to cream butter and sugar until fluffy. Add milk, flax egg, and vanilla mix well.
Add flour mix a cup at a time, mix well in between adding flour
Add drops of red coloring to the dough until you achieve the color you want.
Form a ball with the dough, cover, and chill in the refrigerator for 2 hours.
Preheat oven 375F
Divide the dough in half and roll out on a lightly floured surface to 1/4 inch thickness. Cut dough with a 3 inch round cookie cutter. Cut the circles in half, and place on an ungreased baking sheet. Repeat with remaining dough.
Bake in the oven for 8-10 minutes or until cookies are slightly browned and set. Allow cooling completely before decorating.
Making the Frosting:
With a hand or stand mixer, mix powdered sugar and water until smooth. Add drops of green food coloring as you desire. Blend well.
You can frost the edges by dipping the cookie into the green frosting or use a pastry bag and pipe the edges with green frosting.
Strategically sprinkle the mini chocolate chips on the cookie to look like seeds.
Enjoy!
