Using a black edible marker, draw the watermelon seeds on the red macaron shell.
Remove watermelon ice cream from freezer to soften a little.
Pair similar sized green shell with a red colored shell together to form the cookie sandwiches.
Using a spoon, add about 2 teaspoons of watermelon ice cream onto each green shell.
Carefully sandwich the cookie with it’s pair, being careful not to break the shell.
Repeat to assemble all the cookies
Once all the cookies are assembled, enjoy immediately or store the macarons in the freezer for at least 24 hours to mature.
Enjoy your hard work!
