I fell in love with these cookies from a Rainbows and Race Cars birthday party that was put together by Glory from Glorious Treats. The rest of the birthday party was absolutely adorable as well, but I just love the simplicity and bright colors on this cookie! You could use this design for so many different themes! So cute! Glory features the recipe and tips for her sugar cookies here and a decorating tutorial for icing cookies with royal icing here. You can also find the recipe for royal icing from Wilton here. Happy baking!
