Easy Watermelon Sugar Cookie Ingredients
Butter: You need ½ cup of butter for rich and flavorful cookies.
Shortening: Add 6 TBSP of butter flavored shortening to give the cookies more fats needed to stay moist while baking.
Sugar: Make the cookies sweet & chewy by adding ½ cup of granulated sugar to the dough.
Powder sugar: To create incredibly soft and tender cookies, use ½ cup of powdered sugar.
Milk: Adding 1 TBSP of milk gives the dough a bit more moisture to stay soft, but not crumble.
Egg: Help bind all the ingredients together well by adding 1 egg to the dough.
Baking soda: Using ¼ tsp of baking soda in this dough helps the cookies puff up and rise as they bake.
Cream of tartar: You need ¼ tsp of cream of tartar to create chewy and delicious treats.
Salt: Balance all the wonderful flavors in this dough by adding ½ tsp of salt.
Flour: The structural base of this recipe is 2 ¼ cups of flour.

Buttercream Frosting

Vanilla extract: Enhance the flavors in the frosting by adding 1 ½ tsp of vanilla extract.
Powder sugar: You will need about 4 cups of powdered sugar for a smooth and sweet frosting. The final amount depends on the consistency you want.
Milk: Add 3-4 TBSP of milk to help combine all the ingredients and create a smooth and creamy texture.
Sprinkles: Using a pinch of chocolate “Jimmie” sprinkles for each cookie will be just enough “seeds” for each slice of watermelon.
Food coloring: You need red & green food coloring to create these fun & tasty treats.
How to make Watermelon Sugar Cookies
How can I add watermelon flavor to the frosting for cookies?
To create watermelon-flavored frosting for your sugar cookies, you can add a few drops of watermelon flavoring or extract to your favorite buttercream frosting recipe. Alternatively, you can mix in some finely chopped watermelon or watermelon juice to achieve the desired flavor. It is important to note that adding too much liquid to your frosting can affect its consistency, so make sure to adjust accordingly.

How long are frosted sugar cookies good for?
To keep your Watermelon Sugar Cookies fresh, store them in an airtight container at room temperature for up to 3 days. If you want to keep them longer, you can freeze them for up to 2 months. When thawing, make sure to let them come to room temperature before serving.
Do I need a piping bag for this recipe?
While using a piping bag can help you achieve a more professional look, it is not necessary for this recipe. You can also use a zip lock bag for the piping of the green frosting, just snip off a small corner and go to town!
Tips for making perfect sugar cookies
To ensure that your sugar cookies turn out perfectly every time, make sure to follow the recipe instructions carefully. Use room temperature ingredients, and don’t overmix the dough. Finally, make sure to keep a close eye on the cookies while they bake, as they can easily overcook and become dry.
