Simple rainbow sugar cookies made from a circle cookie cutter! We'll share two ways to decorate them with buttercream frosting. So colorful and delicious!
For the semi-circle rainbow cookies, cut out circle cookie shapes then slice each circle in half using a pizza cutter or knife.Use a small round cookie (or biscuit) cutter to cut out a small section in the center for the arch.
Bake cookies and let cool completely.
Whisk ingredients together for frosting. Seperate into bowls and add food coloring.Fill pastry bags with frosting and desired frosting tips. Use a #5 or #7 tip for the rainbow colors and a #18 tip for the white clouds.
Pipe rainbow onto cookie using frosting bags filled with buttercream frosting.Add clouds by piping on small white stars to each cookie.
For the round rainbow cookies, cut out circle cookie shapes. Bake cookies and let cool completely.Outline cookie in blue frosting. Fill bottom with blue frosting.
Fill in top half of the cookie with rainbow colors. Swirl clouds onto each cookie using the white frosting and star frosting tip (#18).
